Takagi Tankless Water Heater Reviews

Do you need a new water heater? Chances are, you’re not well-versed in the area if you haven’t purchased one for your home in the past. There are several elements you’ll want to consider, especially when you’re deciding over a tank or tankless water heater.

We’ll get into the differences a bit more int he next section, but we’ll mainly be focusing on one company for this review: Takagi. Takagi is a Japanese company that sells tankless water heaters in the US, and they’ve become relatively popular with these appliances.

Ahead, we’ll give you some more information on Takagi and their water heaters, along with our verdict on whether or not these water heaters are the best choice for your home.

Advantages and Disadvantages of a Tankless Water Heater

Before we get into the review of the Takagi tankless water heater, we wanted to touch on the benefits of a tankless water heater in general.

Tankless water heaters won’t begin heating the water until you turn on the faucet. There’s a slight tradeoff here, with the disadvantage being that you have to wait a bit before you can receive hot water.

The benefit is a huge one, though. These water heaters use far less energy than their counterparts because they don’t store hot water.

Other water heaters need to continuously heat the water in the tank, so you always have hot water when you want it. Tankless water heaters, on the other hand, don’t face this issue. You will have to wait a few seconds before getting in the shower, but this will save you a lot of money on your energy bill.

These types of water heaters always run on gas - usually natural gas - which some consider being a drawback. Some will prefer to keep everything on their electricity bill, but a natural gas hookup isn’t as costly or irksome as you might think.

Overall, we think tankless water heaters are the way to go. They’ll save you money on heating costs with the slight tradeoff of having to wait a bit for hot water.

What Are Takagi Tankless Water Heaters?

takagi products

Like a lot of tankless water heater brands, Takagi is a Japanese company that teamed up with an American company to distribute their products in the states. The company Takagi has at its back is AO Smith, which is already known for making reliable water heaters in the American market.

Takagi has been around for over 70 years at this point, making all kinds of large household appliances for their customer. In the states, they’re mostly known for their tankless water heaters, which is what we’ll be focusing on today.

Like all tankless water heaters, Takagi appliances use a gas connection for power. This means you’ll need a gas source in your home, which is almost always natural gas. In some cases, you might need a new pipeline installed when you purchase your Takagi tankless water heater. Some of the models from Takagi, though, run on propane rather than natural gas. This is more expensive on the whole, but some people prefer it so they can save on some of the installation costs.

Takagi Tankless Water Heater Features

Now, let’s take a look at some of the standout features of the Takagi tankless water heater. There are several models that offer a few different specifications, but we’re going to focus on elements that apply to most - if not all - Takagi tankless water heaters.

Knowing that a water heater is decent isn’t enough - you’re probably looking to find out how it stacks up against the competition.

Well, we took a look at Noritz and Rinnai side-by-side with Takagi to see which brand of tankless water heaters came out on top.

Takagi Water Heaters Vs. Noritz Water Heaters

No products found.

Noritz is another reputable water heater brand that’s relatively popular. The energy rating and temperature settings are nearly identical, and both are highly efficient which will save you money on energy costs.

The Noritz models edge-out Takagi in their water flow, but do not have the same integrated temperature controller as the Takagi brand.

The warranty is another place where Takagi shines over the competition. Noritz has the industry-standard 12-year warranty, while Takagi will cover it for 15 years.

Takagi Water Heaters Vs. Rinnai

  • Ultra low NOx emissions

Rannai is one of the biggest competing forces to Takagi, and actually has the edge when it comes to energy efficiency. You probably want to take a hard look at Rinnai if saving on energy costs is the biggest concern for you.

Rannai is even mobile home certified, which means you can use it in a trailer without an issue. The warranty for Takagi is longer - 15 years vs. 12 years - but many of the other specifications tip on Rinnai's favor.

As you might expect, Rinnai water heaters cost more than Takagi heaters on average. The price difference isn’t too much, though, and we would give the nod to Rannai over Takagi for the few, small benefits.

What We Think

On the whole, we think Takagi presents a good value regarding tankless water heaters. There are only a few companies that we rate above Takagi (Rinnai, for instance), but it’s difficult to beat the energy efficiency, reliability, and affordability of a Takagi tankless water heater.

The warranty is one of the reasons the value is so great, here. Most of the other brands will cap you at 12 years, while Takagi covers their products for 15. This might not seem like a lot, but it shows how much confidence Takagi has in their water heaters and their ability to last over time.

Tankless water heaters are becoming more popular in homes as energy costs rise. You don’t have to pay to keep a tank full of hot water on hand, as long as you don't have a problem waiting a few seconds for the water to heat up.

All in all, Takagi is a solid manufacturer of tankless water heaters, and certainly worth considering if you need a new one in your home.

The technology that is integrated into the Rinnai systems allow you to receive maintenance alerts and the option for remote assistance. You can also control your system by installing Wireless Push Button, Wireless Motion Sensor, or even Voice Activation with Amazon Alexa.

The pros and cons of a Rinnai tankless water heater are:


  • Each system is energy efficient, some models more so than others
  • Some models are Wi-Fi and Amazon Alexa capable
  • Models can be controlled remotely
  • All models can be used for an entire home - no need for multiple units

  • to DIY
  • You must have natural gas or propane hook-up for any model

The Different Rinnai Models

Rinnai tankless water heaters use less energy and water and have an average 20-year lifespan. All parts are recyclable and replaceable.

There are three different series of models that Rinnai offers, the High-Efficiency Non-Condensing Technology, the Super High-Efficiency Condensing Technology, and the Hybrid Tank/Tankless Water series.

The High Efficiency, or HE, series has two models: HE Series V and HE +Series RL/RLX.

The HE Series V offers a low budget-friendly option for those trying to save some money. It has an energy efficiency rating of .81, and it can handle up to four running shower heads at a time. This option can be installed either indoors or outdoors and can run on natural or propane gas.

The second option in the HE series is the HE +Series RL/RLX. This is also a great budget buy option and has an energy efficiency rating of .81. This option is also good for up to four running shower heads.

This option also has Circ-Logic technology, which allows recirculation to deliver hot water faster than the HE V option. This technology also gives you Wi-Fi capability and voice activation when you connect your HE RL/RLX to your Amazon Alexa.

You are also able to control your water heater remotely. If necessary, you are able to monitor and diagnose remotely as well.

The next Rinnai series is the Super High Efficiency (SE) Condensing Technology series with the SE Series RUCS/RUS, the Sensei SE+ RUC/RU, and the RUR. All of these options are Energy Star qualified.

The SE series RUCS/RUS is a little more expensive than the HE series options. The energy efficiency rating is .81 and can support up to three running shower heads at a time.

The Sensei SE +RUC/RU series is also more expensive. This series has an energy efficiency rating at .92 and can support up to four shower heads at once. This option also has Circ-Logic technology, allowing it to have Wi-FI and Amazon Alexa capability.

This option also has the ability to control, monitor and diagnose the heater remotely.

The Sensei SE +RUR model is similar to the RUC/RU model in price range, energy efficiency rating and shower head support. It also has advanced technology, but instead of the Circ-Logic, it has the 360 technology.

The 360 technology is a more advanced version of Circ-logic, allowing all of the same features. This model is a great option for larger homes that use more water because of the ability to preheat the water.

The last Rinnai water heater series is the Hybrid Tank/Tankless Water series. This series has two options: RHS and RHS100, both are the most expensive option from Rinnai. These options do not have an energy efficiency rating, nor do they have a recommended shower head usage.

These models do offer faster hot water delivery option, and the RHS100 has the Amazon Alexa voice activation option.

It seems that the HE and SE series are the more efficient and better option for buyers.

The Rinnai water heaters come with flexible venting options for easier installation. The venting options allow for indoor or outdoor installation.

What Are Other Tankless Water Heater Options?

There are many other tankless water heaters on the market. Here are a few options to compare to the Rinnai series options.

The Rheem RTEX 13 Electric Tankless Water Heater is a compact unit that does not need a lot of power to run. It is an electric water heater, which allows people that don’t have a gas or propane option to still have a reliable source of hot water.

The Stiebel Eltron Tempra Plus 24-kW is an electric heater that has advanced flow technology that allows the temperature of the water to maintain stability even if you adjust the flow rate. It is a compact and quiet water heater that costs roughly $685.

The Atmor also has a water sensor that begins heating water for future use as soon as you turn on the hot water. Once you turn the tap off, the sensor goes off. This saves energy by not running unnecessarily.

How Do Rinnai Tankless Water Heaters Compare?

With the many tankless water heater options available, it seems that Rinnai still holds up to their competition.

Many other options are affordable options for small homes with one or two residents and not a lot of water usage. For the larger homes or businesses, Rinnai seems like a no-brainer.

Rinnai has several options to meet the needs of many different customers. They also offer versions for people that prefer more technology or for those that do not.

Rinnai is affordable, albeit some models are much more expensive than their competitors. A major difference and justification for the cost, is the amount of hot water the Rinnai can produce.

Many of the competitors are only good for one shower and one faucet running simultaneously. Rinnai has several options for larger homes to run multiple showers and faucets at the same time.

With Rinnai’s efficiency and many different options, this seems like a solid choice for a tankless water heater for your home or business. The only downfall is that it is only available for those with natural gas or propane availability.

Rinnai Rebates and Financing

Rinnai offers different rebates for several different product models. If you visit their website, you can find the rebate form, as well as the fine print. There are specific dates that you must have purchased your Rinnai product, as well as a cut-off time for your rebate form return.

Rinnai also partners with Service Finance Company, LLC to offer flexible financing options. This is a safe and secure paperless process that can be done from your computer, tablet or phone. The process provides quick approval decisions and allows same-day funding. Approval rates are high, as well. You have the easy loan management and no prepayment penalties.  

Noritz Tankless Water Heater Review

color gray water heater

Getting enough hot water, precisely when it’s needed, isn’t an easy task, even if you’re using a traditional tank. This difficulty is only amplified when you’re working in a cold environment or with a large number of bathrooms where the water might be needed all at once and in a more significant amount than a tank could provide, while still ensuring its temperature.

In these situations, a tankless water heater is the only way to ensure that you can keep a constant stream of hot water flowing to all of the bathrooms in the building. If you’re at home and you can’t get hot water, it sucks. But imagine paying for a hotel or an office and not getting hot water in the morning, that’s even worse.

Tankless water heaters aren’t typical in homes, although many large homeowners use them, they are very prevalent in larger buildings like hotels. In these buildings, it would be nearly impossible to have enough hot water stored up at all times to ensure that everybody is always happy with the water that they get.

Shower Filters from FilterWater.com

It’s necessary to heat the water at the source as it’s flowing to the endpoint to prevent issues. This system allows it always to be hot and prevents it from cooling down on the way to the bathroom where it’s needed. Overall, tankless water systems can be far superior in a large number of situations.

What is the Noritz Tankless Water Heater?

Noritz is one of the most famous brands in the water heating industry, perhaps an obscure award, but one that lets them know the quality of the product that you’re getting. For many years they have been producing a vast range of different products, including their popular indoor condensing direct tankless heaters.

That’s a lot of words, but all it means is that there isn’t a tanker of water that stores and heats water in the traditional manner. This heater is extremely efficient, reducing the amount of energy that is needed to heat the water and therefore saving you money every month of your power bill.

Each of these tankers is capable of heating enough water for two bathrooms in a southern climate and 1.5 bathrooms in a northern climate. For a homeowner that’s great. But as a hotel owner that might not sound like a lot. Fortunately, the cost of these devices is tiny when compared to many large-scale boilers and heaters.The heater itself is capable of heating up to 6.5 gallons of water every single minute, plenty if you’re using the shower or even filling up a huge bath. This device ensures that you and your guests are constantly getting a supply of newly heated water so that you can wake up happy, rather than cold water.

Noritz has been innovating in the industry for over 60 years, and these heaters are their latest venture into ensuring that we can use our homes with less effort than ever before. As the original creator of the modern electronically controlled tankless heater, you can be confident that you’re buying from an industry leader.

How Does it Work?

Tankless water heaters work uniquely when compared to the traditional tank systems that you are probably accustomed to. These older devices store a tremendous amount of water which is then heated to a high temperature and insulated in a large container for hours at a time.

This system is incredibly inefficient because most of the time you are not using hot water, but it’s still being kept ready for you. While this does have one advantage, you get your hot water a few seconds faster, the cost can be considerably higher, and it’s a waste of energy.

On the other hand, a tankless water system works by pushing regular water through an intense heating device where it increases to the precise temperature that you need. From there it’s pumped through to your bathroom for you to enjoy, albeit it might take a few seconds for the water at the faucet to heat up.

These tankless systems have a few advantages, primarily that they can reduce your energy usage by minimizing unnecessary heating of water in a tank. But they can also ensure that you have a constant supply of hot water.

While a tank system gives you hot water instantly when it runs out you need to wait hours for it to heat back up. Whereas a tankless system might require a few seconds to warm up, it will never run out because the water is heated on its way to your bathroom, therefore giving you a limitless supply.

Depending on whether you’re living in a small home by yourself, or with a large family or running a hotel, one system might be superior for you. If you find that your water is often cold, particularly when others are using it, you should highly consider switching to a tankless system which can fix this issue for you.

Whereas if you’re living by yourself, you might find that your hot water never runs out and your power bill is manageable. In this circumstance, you might not need a tankless system, particularly if you don’t foresee your water usage increasing in the future.

What Makes the Noritz Tankless Water Heater Unique?

The Noritz Tankless Water Heater was the first of its kind. As the industry leader, they have developed a specialized product that is capable of pumping a large amount of water to your bathroom while keeping it at the perfect temperature at all times.

Perhaps what separates this heater in particular from some other on the market is that it’s capable of producing 6.5 gallons of hot water every minute. 

Whereas many alternatives might only reach half this number, this ensures that you and other people can also enjoy steaming hot water at any time. Here are its main selling points:

  • Capable of 6.5 gallons of hot water per minute
  • Unlimited supply of heated water on demand
  • Affordable compared to large tanks
  • Can reduce gas costs over time

Even if you’re living by yourself or in a small house, this flow of water is critical. If you’re using the dishwasher or the washing machine, you might find that smaller heaters cause the shower to go cold, while this more powerful device can guarantee you a constant flow of hot water for up to 6.5 gallons per minute.

The device itself is also relatively small, especially when you compare it to the size of a traditional tank boiler. While this might not be important for some people, if you live in a very small house then every foot counts. By reducing the size of your heater, you can regain space for you and your family.

The pricing of these tankless heaters from Noritz can vary greatly depending on the supply at the time of purchase. At the time of writing, these heaters are available for slightly over $​$$ each, making them very affordable when compared to tank system but more expensive than some other tankless devices.

This system should last you for years to come, and many homeowners will find that they can save themselves money by reducing their power bill by not constantly heating water that they aren’t using.With little to no upkeep required, the device should last you for years to come without the need for maintenance of any kind. However, it’s likely that you will need to pay a professional to install the heater for you and to purchase some PVC piping and brass pipes for the water to flow through.

These expenses can differ drastically depending on what you are buying and how large your house is and therefore it’s unfair for us to unpack the cost and to include it in this pricing. However, keep in mind that it’s likely that you’ll be out of pocket more than the sticker price for the heater itself.

Noritz Tankless Water Heater Reviews

During our extensive research we found that while many of the lower cost alternatives had solid reviews, many problems came with them including the need for expensive stainless-steel venting and hot exhausts.

On the other hand, the Noritz heaters are high-efficiency and therefore can be used only with simple PVC venting while reducing the cost of your energy bill. Over time the expensive upfront cost of these more efficient systems pays itself off, leaving you with a lower price throughout decades.

One reviewer wrote an extremely detailed account of his experience with the system and found that it “fit [his] needs perfectly, especially considering the smaller size” of the device. Similarly, he was able to install it himself because it’s “not too difficult,” meaning that you might be able to save money on the cost of installation cost.But the primary reason for consumers to opt for this tankless heater over some of the cheaper alternatives is that it will save you money over time. According to him, his “natural gas consumption is about 10-20 percent lower” meaning that he can reduce his yearly bill by a fifth and therefore save money.

If you’re looking at a tankless system as a long-term investment, which you should be given it lasts for decades, it can be worth investing in a more expensive system upfront to save you money in the long run.

How it Compares


Takagi T-KJr2-IN-NG Indoor Tankless Water Heater, Natural Gas

Buy on Amazon

The most popular alternative to the Noritz tankless system is the Takagi T-KJr2-IN-NG which is a similarly powered and sized system which gives you instant hot water. The systems work in almost an identical fashion, but the difference is that the Takagi is a fraction of the price at around $$.

For this reason, many consumers choose to opt for the cheaper system because it requires them to spend less money upfront. However, it’s important to consider that it’s not a high-efficiency condensing system and therefore it will require more natural gas to produce the same results.

The effect of this is that while you may pay less money upfront, you’ll find that your bills are higher than they would have been otherwise. As a result, over a decade the cost to yourself will be higher with the Takagi than it could be with this heater.

Therefore, if you find yourself strapped for cash, then we would recommend opting for the Takagi heater which is a fantastic and durable product. However, if you can afford the extra few hundred dollars up front, then you’ll be able to save yourself money in the long run by using a high-efficiency water heater.

What We Think

It’s our opinion that the Noritz Indoor Condensing Direct Tankless Hot Water Heater is one of the best on the market, especially if you’re looking for a high-efficiency device that can reduce your energy costs over time. The reason for this is because the system is made of durable materials, is high efficiency and lasts for years.

Plus, during our research, we found many happy customers who had a fantastic experience with the product, including finding it surprisingly easy for them to install without any professional help. These added benefits can help to reduce your upfront cost, bringing it inline with a competitor while saving you money on gas.

It does have some small downsides, including the high upfront cost and by using plastic piping, which saves you money, it’s possible that there could be an increased chance of them breaking. However, these downsides are tiny in comparison to the huge flow of 6.5 gallons of hot water per minute.

This speed of water flow means that you can be using your shower on the maximum temperature and still utilizing the washing machine or dishwasher and not run out of hot water.

Plus, you get all of the standard benefits that come with a tankless heater including an unlimited supply of hot water because it passes a heating element on the way to your bathroom, rather than being pre-heated in a large tanker in a closet. Similarly, this can give you greater control over the water temperature, making it hot rather than just warm.

What Is The Ecosmart Tankless Water Heater And How Does It Work?

Ecosmart Tankless Water Heater and How Does it Work?

The Ecosmart Tankless Water Heater is one of the largest and most energy-efficient units on the market. It is available in different sizes and has some impressive features. Its compact size makes it easier to install than tradition tank units but doesn’t affect its performance. There are several pros and cons to this unit.

Shower Filters from FilterWater.com

The Ecosmart Tankless Water Heater is one of the most powerful tankless water heaters on the market. It has been available for several years and has become popular with homeowners. Most people are used to using traditional water tanks in their homes and don’t put much thought into changing them.

This tankless water heater changes everything. It works by heating the water as users need it as opposed to traditional hot water tanks that heat the water ahead of time and store it in the tanks. They have to use additional energy to keep the stored water hot until someone uses it.

These units work differently. They don’t use any energy to heat the water until the water is needed. When the hot water is turned on to wash dishes, take a shower, or for any other reason, the water travels through a flow sensor. Users can control how much water flows through at a time to have more control over their energy usage.

The sensor signals for the electric element to start heating the water. As the water flows through the heat exchanger, it heats up. The heat exchanger adjusts to keep up with the amount of water being used, so the temperature stays consistent. The hot water travels from the unit to the faucet or appliance that needs it.

This specific water heater comes in the form of a compact white unit with a black control system. Inside the box are all the sensors and electrical components that heat the water. A dial on the outside of the box allows the user to control the temperature. The water heater is small so that it can be installed on a wall, under a cabinet, or even behind a door. It connects to the plumbing and plugs into the home’s electrical system.

Tankless water heaters are more energy-efficient than traditional tanks and also much smaller. The only water that is heated is the water that is needed at the time. That means no wasted energy. That is just one of the reasons tankless hot water tanks have become so popular. Anyone who cares about energy usage or has gone green will appreciate the efficiency of this device.

What Makes the Ecosmart Tankless Water Heater Unique?

A unique aspect of this product is its size. Most of us think of water heaters as big tanks that need a closet or hidden area. They are ugly eyesores that just don’t belong in plain sight. The tankless water heater is much smaller and less noticeable. There is no need to find a specific storage space; it just attaches to the plumbing and functions the same as a larger hot water tank. It produces plenty of hot water when you need it. On average, it can heat three gallons of hot water per minute. On colder days, or in colder areas, it may be necessary to pause between showers if you want to keep the water warm. Colder water takes longer to heat so the average output may be affected by lower water temperatures. Another unique aspect of the water heater is that homeowners can control the temperature. Temperature can be increased or decreased one degree at a time. The water heater does operate on a 220 amp service, so homeowners who do not already have this amp service installed may need to do so before purchasing this product.

The Ecosmart Tankless Water Heater is an affordable option for several reasons. The equipment itself is similar in price to a tank water heater, but it is much smaller. It’s also easy for homeowners to install on their own, which means no installation fees. It may require some minor plumbing knowledge, but the installation instructions are clear, and the process is relatively simple. The water heater is available in different sizes. Depending on your needs, you can expect to pay between $200 and $500 for it. The real affordability comes in the form of efficiency and energy use. The water heater has a 99 percent efficiency rating. That is enough to save you up to 50% off your current energy bill. Despite the high-efficiency rating though, the water heater is not Energy Star qualified. Due to the energy savings, most people have found that the water heater pays for itself in a short period.

Public Perception

Since the Ecosmart has been on the market for several years now, there are plenty of user reviews online. Most people are raving about that impressive energy efficiency rating. Owners are also impressed with the overall performance of such a small unit. Many are in disbelief that the Ecosmart can heat water better and faster than their traditional tank units.

One owner explained that she had owned her Ecosmart unit for several months and had already saved hundreds of dollars on her energy bills. She also revealed that the tank works better than her older, 50-gallon tank that she removed before installing the Ecosmart unit.

Consistency was another popular feature of the unit. Users found it convenient to control the temperature of the water digitally. They no longer had to worry about the temperature of the water changing in the middle of a shower. They just chose their preferred temperature before turning on the hot water, and the unit was able to maintain that temperature until they were finished.

It seems that many people were happy about the lifetime warranty offered with the unit. Several people wrote in their reviews that some of the parts had gone bad over time, but they were able to order the new parts at no cost due to the warranty. Of course, they still had to pay to have those parts installed on the unit, but the money they saved on the replacement parts covered the cost of labor in most cases. Some people did have warranty issues when electric or plumbing problems damaged the pieces.

When it comes to installation, users offered mixed reviews on the difficulty level. Some people were relieved that there were clear directions that allowed them to install the unit themselves. One user explained that he saved hundreds of dollars on installation costs. He admitted that he struggled with some aspects of the installation while doing it himself, but was also quick to say that the installation guide was a big help.

Other people felt like the installation process was beyond what the average homeowner can do on their own. There were also concerns about how installing the unit themselves could affect the warranty. Many said that they started to install the unit on their own but ended up calling in a professional to install the unit correctly.

A common complaint of many customers was loose connections. Many people complained that they were either hard to tighten initially, became loose over time, or popped off completely, causing a major mess. A few people even mentioned that they found puddles and mold around connections that they didn’t realize were loose and leaking.

How It Compares

product specs

The Ecosmart stands out among other tankless water heaters because of its energy efficiency.  While almost all tankless water heaters are more efficient than tank water heaters, few compare to the Ecosmart. It also has a sleeker and more modern appearance than similar units.

Some tankless water heaters are point-of-use heaters. That means they are connected directly to the appliance or faucet that they will heat. Some people may prefer these types of heaters, but the Ecosmart is far more convenient as a whole-home unit. Only one Ecosmart unit needs to be installed in the home, and it heats the water for various appliances or water output points.

The digital control panel is another thing that few other units offer. It’s much easier to use than a push-button unit, and it looks nicer too. The sleek design also makes it less noticeable than other similar tankless water heaters. It can be hidden easily and blends in well with other electrical outlets and device.

Another thing that sets the Ecosmart apart from other tankless water heaters on the market is the fact that it can heat numerous water sources at the same time. It can run up to four showers and a sink at simultaneously. That means no more fighting over hot water in the morning.

What We Think

Ecosmart is a big name in the tankless water tank industry. They offer some of the most efficient and affordable units on the market.  They have excellent customer service, and they seem to take pride in their products.

Their units may have mixed reviews, but for the most part, they seem to perform well. The energy efficiency has been mentioned several times, and there’s no doubt that it is a notable feature and selling point for these units. Everyone wants to save money and for many people, energy bills are their most significant monthly expenses. If a small unit can bring 50% savings, why not give it a try?

A lot of people are put off by the initial cost of the unit and even intimidated at the thought of installing it themselves. It’s important to look at the unit as an investment and understand that it can pay for itself in a short period. While it is designed for owners to install themselves, that doesn’t mean you have to do it. If you aren’t comfortable with the installation process, you always have the option to call a professional.

It performs better than most people expect. It’s easy to look at this small unit and get the impression that it won’t be able to heat as well or as much water as a large tank unit. After a couple of months of using it though, it becomes clear that it’s a powerful little water heater. Most people are beyond impressed with the performance after owning it for just a short time.

It’s great for large families and people with more than one bathroom. It can keep up with busy lifestyles and the fact that it can heat water for several different sources at a time is very convenient. It is essential for buyers to choose the right size for their home as there are several options available. Buyers also have the option of selecting one unit that can heat water for the entire house or multiple tankless heaters that they can install throughout the home.


The water heater comes with a lifetime warranty. While that’s a pretty impressive warranty, buyers should be aware that it only covers parts and not labor. It also only applies if a qualified person correctly installs the water heater unit. That might stop the average homeowner from doing it themselves. Some people reported installing the water heater themselves and having no issues with the warranty. Others said they were denied the warranty claim because they had installed the water heater themselves and the company claimed the defect was due to installation issues. Still, the warranty is nothing to scoff at. Knowing the piece can be replaced if there are issues, can give homeowners some peace of mind.

Coupon and Deals

Coupons, discounts, and special offers are often available from Ecosmart for their tankless hot water units. You can sign up for email offers and check their website for sales events. Many of the stores that sell these units also offer specials and deals. You may also want to check Groupon and other coupon websites regularly to see if they are offering any special coupons that could help save you money on these units.

Rheem Water Heater Reviews

Rheem Water Heater Reviews

Rheem Manufacturing is an HVAC company that offers a full line of top rated water heaters ranging from electric, gas, hybrid, and solar options. If you've never heard of the company, you may be a newbie to the heating and cooling industry. Rheem Manufacturing has been producing water heaters since 1908 and has gained a reputation for brand recognition as a top performer in numerous category rankings. Do Rheem's assortment of hybrid, gas, and electric water heater systems live up to their claims? It's helpful to understand the many distinctions among Rheem water heaters and learn more about the warranty information, lifespan, price point, durability and performance of these popular water heaters to answer this question. Read on for an unbiased, in-depth analysis of Rheem's top selling water heater systems so that you can decide for yourself.

What Is a Water Heater and How Does It Work?

A water heater is a standard device in most homes, used to heat your home's water supply to a temperature that is comfortable for bathing, showering, and essential for in-home laundry. That figure hovers around 120 degrees Fahrenheit.

Water heaters gained popularity roughly a century ago with the rise of the industrial age, and are now utilized by nearly every homeowner who maintains proper plumbing, heating and cooling systems.

Traditionally, water heaters were available in gas-fueled models that relied on large tanks to operate. While these types of water heaters remain a popular choice, today's options are available in tankless, electric, and hybrid models. They offer several advantages over the previous ones.

What is UEF? Is UEF Rating Different From High Efficiency?

UEF ratings are intended to represent performance, energy efficiency accurately, and simplify the process of selecting a water heater. UEF is not a new feature of water heating systems but condenses most rating criteria that have been in place for decades.

First Hour Delivery And First Hour Rating

The terms first-hour delivery and first-hour rating refer to the amount of hot water a water heater can yield within its first hour of operation.

First-hour delivery (commonly abbreviated FHD) is included in most water heater product specifications. First-hour rating, or FHR, is an alternate term for first-hour delivery.

Rheem Water Heaters

Rheem Manufacturing is an industry leader in both water heaters and air conditioning systems. For our purposes, we'll be focusing on Rheem's wide range of water heater systems. To explain how Rheem's water heaters work in detail, it's helpful to break Rheem's water heaters into their respective categories.

Rheem water heaters are available in four main types, including:

  • Gas and propane water heaters
  • Electric water heaters
  • Solar
  • Electric

These categories are further divided into classifications depending on efficiency, performance, and tankless models.

Generally speaking, Rheem's gas water heater models stand out among competitors as one of the most popular choices for homeowners in search of a mid-range price point, with varying class performance rankings.

Rheem's gas water heaters can be divided into the following categories:

  • Performance
  • Performance Platinum
  • Performance Plus
  • Professional Classic
  • Professional Prestige

These models rank incrementally: with Rheem's Performance water heater coming in with the lowest UEF rating, while Rheem's Professional Prestige model receives top ratings in UEF, warranty, and ENERGY STAR rating.

For single-family homes, the Rheem Performance gas water heater is a popular choice that efficiently accommodates the average homeowner with an output rate of 85 gallons/FHR. For families seeking an environmentally conscious yet affordable alternative, Rheem's Performance Platinum gas water heater makes the grade with .58 UEF and ENERGY STAR certification.

The Efficiency of Rheem Water Heaters

Rheem is also an industry leader when it comes to energy efficiency, and the brand offers numerous electric and hybrid electric models that receive top rankings.

The company's electric water heaters are also ranked by performance and class, falling into seven main categories:

  • Marathon series
  • Performance series
  • Performance Platinum series
  • Performance Plus
  • Professional Classic
  • Professional Prestige
  • Hybrid

As you can see, Rheem cuts no corners when it comes to offering an option to suit the needs of every homeowner, but do Rheem's electric water heaters live up to their efficiency and performance claims?

The short answer is yes—Rheem's electric and hybrid water heaters deliver on their ENERGY STAR ratings and performance expectations.

The more detailed, slightly longer answer is that Rheem's electric and hybrid water heaters often receive lower ratings when stacked up against hybrid and electric models offered by Rheem's closest competitors.

Depending on the series and model you select, ENERGY STAR and UEF ratings vary. During real-world performance tests, certain Rheem models earn less than impressive test scores for efficiency, output, and overall mechanical performance.

What Makes Rheem Water Heaters Unique?

Rheem stands out as a brand with a history dating back to 1908, first manufacturing water heaters and then moving on to produce air conditioning systems.

Rheem split into two sperate HVAC divisions around the year 1970, further developing each arm of their manufacturing centers and expanding product selection. The manufacturer has a reputation for producing durable water heaters at a mid-range price point.

Along with the durability Rheem has become known for, the company offers the largest selection of water heaters available and is the leading producer of water heating systems in North America.

Rheem offers a remarkably extensive line of water heaters that are classified by type, performance, and class. Rheem offers more ENERGY STAR rated electric and hybrid water heaters than any other manufacturer.

Rheem's products typically fall within the mid-range price point. While the company offers hybrid and solar options, these models weigh in at an increased cost over gas and electric alternatives.

Due to Rheem's extensive selection, the company can offer mid-range price point options for nearly every type of water heater they produce. Rheem offers more ENERGY STAR rated water heaters at low, mid-range, and high-end price points than any other manufacturer.

Rheem's Brand Reputation And Story

As mentioned, Rheem is a brand associated with durability and tradition. While the manufacturer's inception dates back to 1908, the company continues to produce modernized, contemporary water heating options to accommodate today's homeowner with ease.

Rheem is also a leader in corporate social responsibility, giving back the communities where they live and work.

Last year, Rheem opened an innovative hands-on training center located in Lewisville, Texas. The new learning center provides local residents with an opportunity to learn the ins and outs of the HVAC industry with Rheem's industry-leading know how.

The facility includes state of the art virtual reality diagnostic testing labs, live demonstrations, and product showrooms. Rheem's Dallas Metro Innovation Learning Center is one of five training centers across the United States and Canada.

Rheem furthers their commitment to corporate social responsibility by working to produce eco-friendly products that reduce environmental impact. In Southern California, Rheem partners with local natural gas companies to develop low emission water heaters, a primary concern for those living in regions with poor air quality across the state.

Rheem is a favorite brand of many technicians in the heating and cooling industry, who prefer to work with Rheem water heaters primarily because the maintenance that they require is simple and straightforward.

Overall, Rheem's water heaters carry brand recognition, impressive warranties, and require little maintenance.

How Does Rheem Compare To The Competition?

Rheem receives top rankings in nearly every category of rating including efficiency, performance, pricing, durability, and installation. Rheem is also favored for its extended warranty options.

Possible Disadvantages of Rheem Water Heaters

What We Think of Rheem Water Heaters: The Final Vote

Our verdict is that Rheem water heaters are a suitable, top-rated choice for the average homeowner and mid-size family that require little maintenance and stand out among competitors with the largest selection available.

That means that Rheem's wide range of water heaters will suit most families, but it doesn't necessarily mean that Rheem is the number one choice in every performance category, for all homes and families.

Factors including family size, indoor plumbing system, the size of your home, as well as the type of water heater you prefer will significantly impact your final decision and water heater purchase. For families in the market for a whole-house electric water heater, close competitors outrank Rheem models in efficiency and overall performance.

As previously mentioned, families who prefer to opt for electric or hybrid water heaters to reduce their environmental impact, especially large families, may find higher performance specs and grades on real-world testing from similar models offered by Rheem's competitors.

Outside of exceptionally large families and homes with highly specific requirements for their water heating systems, Rheem easily accommodates the needs of the average homeowner and offers the broadest range of models available at a price point to suit nearly every consumer's needs.

Ultimately, the durability of Rheem's water heaters and the reliability of its warranty and customer service reinforce Rheem's status as an industry leader.

Coupons, Deals, And Rheem Water Heaters At The Lowest Prices Available

An added advantage of Rheem's endless selection is that sales and discounts are frequently available when purchasing the Rheem water model that you are most interested in.

Navien Tankless Water Heater Reviews

navien tankless water heater

navien tankless water heater

If you need a new water heater, but space is limited, a Navien tankless water heater may help. Tankless water heaters save space and can provide just as much water heating as any competitor’s water heat​​​​er.

What Are Navien Tankless Water Heaters and How Do They Work?

Tankless water heaters are one of the smallest water heating units available. They can be wall mounted and heat water on demand instead of holding heated water in a storage tank nearby.

Shower Filters from FilterWater.com

When a user turns on a faucet or water system, the tankless water heater instantly heats the water passing through it. Other water heaters hold large amounts of pre-heated water in a tank, which must sit around your home taking up space. They also require maintenance of their own.

Tankless water heaters often need professional installation, because they need a dedicated ventilation system installed. They use larger natural gas pipes and equipment than other heating units, which can give them a higher initial installation cost.

However, they are one of the most energy efficient water heaters. Because they do not have a tank of water whose temperature they must maintain, they save significantly more money and energy over time. An average sized tankless water heater uses half as much energy in one year.

Navien is a company founded in Japan in 1978 to produce boilers. Navien has a North American headquarters in Irvine, California.

The modern Navien brand was bought in 2006 and has been bringing hot water to homes ever since. It is still tied to water heating going all the way back to 1982, however, when its predecessor launched Asia’s first condensed gas boiler.

Navien was the first company to adopt EN (European) standards for each of their water heating units. They also put their green energy units and energy efficient water heaters at the forefront of their marketing.

Their units can be found listed on the Energy Star website, an EPA run website which tracks the energy efficiency of household appliances like water heaters. Because they are one of the most energy-efficient forms of water heating, Navien intends to expand their catalog of tankless water heaters, and focus more on them in the future.

Almost all Navien tankless water heaters use natural gas and propane to heat water. They can be connected to either system and use either heating material interchangeably.

Navien tankless water heater units use steel coils instead of copper for heat exchange. Copper coils exchange heat more quickly but break down far faster. Stainless steel coils, on the other hand, last for far longer and use a natural layer of oxidation to avoid rusting due to water.

What Makes Navien Tankless Water Heaters Unique

Navien Advanced Series

Navien Tankless Water Heaters

Navien NPE series condensing tankless water heaters deliver an endless supply of hot water for any size home. Besides providing hot water where and when it’s needed, Navien NPE series condensing tankless water heaters offer homeowners the following benefits.

    A Navien tankless water heater can heat a continuous flow of water. This makes it capable of running large quantities of hot water that tankless heaters could not. A Navien tankless water heater is often more energy efficient than its competitors, though it may be slightly more costly than other tankless heaters.

    Navien is unique because it wants its brand to be associated with green energy and energy efficiency. Its units meet standards as high as 0.97UEF(Uniform Energy Factor)-0.99EF (Energy Factor), the highest energy efficiency in the market.

    Navien tankless water heater technology uses steel heat exchangers instead of the industry standard of copper material. Stainless steel heat exchangers are less likely to be damaged when the unit is used over a long period.

    Navien products are on the high end of tankless water heaters. They often have a button that recirculates the water in your pipes outside the unit, to remove any residual cold water.

    Almost all of their new models also have Wi-fi connectivity, so you can activate the unit and run hot water when you are returning home before you ever step through the door. These features can make them feel like luxury water heaters but do increase the price somewhat.

    On the practical side, a series of internal sensors track the condition of your Navien tankless water heater. They do a better job of warning you about malfunctions than other tankless units.

    Navien tankless water heaters have more optional accessories than many other brands. The HotButton is an accessory you can install to recirculate cold water, so your shower is hot the moment you turn it on.

    Because tankless water heaters can struggle to maintain flow to multiple devices at once, many Navien tankless water heaters can be cascaded. This means that if you connect multiple tankless units to the same system, they will work in sync to increase the flow of hot water to your faucets and appliances.

    The Navien Advanced Series comes with a space heating option. It uses an H2Air Kit to produce warm air and distribute it through ducts. This means some Navien tankless water heaters can act as heating units in your home, though they’re less efficient than dedicated heating units.


    Best price of the navien tankless water heater

    Image via: Pixabay

    Most Navien tankless water heater units cost between $1000 and 1500 dollars. These prices are primarily for new units and refer to the cost of the tankless water heaters themselves.

    Installation, which is often a necessary cost with tankless water heaters, can be between $500 and $1500 itself. The cost of installation varies based on some factors in your home.

    The biggest of these conditions is whether you install a tankless water heater on the inside or outside of your home. Most units need to install a ventilation system, but this is considerably easier if it is installed outside the home.

    Installing pipes to help recirculate cold water can make installation more costly. Installing a unit inside the home will require ventilation to the outside, and may take additional pipes and materials as well.

    Navien has several optional costs as well. The Navien Advanced Series has a remote you can buy which allows you to manually control water temperature and the recirculation timer.

    This remote can cost an average of $80. Another feature, the Navien HotButton, is an accessory that can be installed in your shower. One press of the button causes the water heater to reheat the water in your pipes. This feature can also cost around $80 though, and you may have to pay for installation.This remote can cost an average of $80.

    Public Perception

    Navien water heaters are considered a high end or luxury brand of water heaters. Several of their units match the highest standards in energy efficiency that tankless water heaters can have. As a result, they are especially beloved by green energy supporters and energy-efficiency activists.

    Because of their cost, they aren’t considered as accessible by the average household, however. They also feature many unique devices, such as the Wi-fi control system, which some reviewers complained was too technical for use in their home.

    Navien offers a 15-year warranty if you have the device installed by one of their licensed professionals. This has given them a good reputation among the Better Business Bureau since it primarily counteracts one of the biggest complaints about their units; mechanical failure in the first ten years.

    Overall, many testers said that Navien water heaters are the premier choice for anyone who wants to make their home more eco-friendly. They’re considered a bit more expensive than their competitors, but testimonies agreed that it was a fair increase in cost due to how energy efficient Navien units were.

    How It Compares

    Bosch 940 ES NG Tankless Water Heater, Natural Gas
    • 199,000 max input (BTU)
    • Highest capacity non-condensing model
    • 9.4 gallons per minute capacity at 35F degree rise
    • Vents vertically or horizontally with 3" or 4"...
    • Electronic ignition and patented burner design

    The main advantage of a tankless water heater is that it warms a continuous flow of water. If you need to run a large amount of hot water, such as for a bath, tankless water heaters are preferable.

    On the other hand, they sometimes only connect to one water line. If you don’t buy one of the larger tankless water heaters, it may only service a single faucet or area of your home.

    Tankless water heaters are often one-fifth of the size of any water heater with a standing tank. If you have limited space, they are far easier to squeeze into your home than other water heater styles.

    Navien doesn’t produce as many unique tankless water heaters as its competitors, such as Takagi or Bosch. They have a unit in each size range, however, so there should be a Navien tank in the right size for any home or building.

    As a company, Bosch is their largest rival. Bosch is a Global 500 company and produces far more models than Navien. Their units are often simpler, but they are larger and require more space inside the home.

    The reviews of many Bosch products indicate they’re good at producing low-cost or average water heater units. Bosch also produces electrical water heaters, while Navien exclusively produces gas and propane units.

    Takagi tankless water heaters, also known as AO Smith heaters, are also a rival of Navien. Takagi water heaters have one of the lowest rates of malfunctions in the first ten years. Navien, on the other hand, has one of the highest.

    Takagi T-KJr2-IN-NG Indoor Tankless Water Heater, Natural Gas
    • 140,000 BTU. Voltage: AC 120V
    • 6.6 GPM max flow rate. Water connection location-...
    • 4-Inch category III stainless steel venting...
    • Inlet, outlet thermistors for constant temperature...
    • Energy factor of 0.81-0.83

    They are the opposite of Navien in several ways. Takagi tankless water heaters are designed for whole households. Several of their models are EPA compliant, but other than that, they put no great emphasis on energy efficiency or eco-friendly design.

    Navien is considered a luxury brand of tankless water heaters. All of their units are highly efficient, and they produce some of the largest capacity models on the market. They are considered a top brand which many companies in the industry strive to compete with.

    However, their units are considered a bit too technical and are considered more prone to malfunction than their rivals. Perhaps because of the excessive sensors and technological features, they are prone to mechanical failure within ten years of installation.

    What We Think

    If you’re trying to make your home as energy efficient as possible, and have the money to do so, a Navien tankless water heater is a must. They are among the most energy efficient additions you can make to your home.

    They’re also a good choice if you’re building a Smart Home. If you want to run a bath the moment you walk in the door, you’ll love their connectivity. They allow you to track the amount of water passing through your system, recirculate cold water, and have many other Smart functionalities.

    Navien tankless water heaters might not be the right choice though if you’re on a budget. They require costly installation, though it’s no more expensive than other tankless water heaters.

    The units themselves are also not known for their longevity since more electronics means more likelihood of malfunctions. While their warranty covers this well, many users pointed out it is easily voided if the installation wasn’t done by a profession from the Navien company itself.

    Regarding the nitty-gritty though, the stainless steel coils and other innards of a Navien tankless water heater last far longer than copper coils and the parts of other heaters. So if you are fine letting a sensor blink out without fixing the electronics, it will still function well internally for many years. Just remember that you’re paying a higher initial cost for the unit due to those electronics.

    The last thing to consider is if you want a tankless water heater. Navien specializes in tankless units, which can take up far less space than a water heater with a tank.

    However, water heaters with tanks are better if you want to run multiple devices, like a washer and your faucet, at the same time. They are two devices designed for different purposes, so a tankless water heater isn’t necessarily an upgrade from one with a standing tank.

    One of the reasons for Navien’s reputation for high price tags is that they answer this challenge though. The ability to cascade their tankless water heaters to help provide water to multiple devices is rare in tankless heaters and sets the brand apart because Navien tanks can handle bulky water demands.

    What Is a Bosch Water Heater?

    Bosch is a German manufacturer located in Gerlingen, Germany. They started out way back in 1886 with founder Robert Bosch, and the company is ranked one of the leading choices for water heaters in Europe today.

    • Benchmark temperature stability achieved with an...
    • Inlet water filter featuring easy external access

    • Introducing the water heater mobile app for sizing...

    Known for their innovative, efficient, and reliable designs, Bosch quickly became a water heating industry leader. Today, they have over 350 subsidiary companies under their belt and the company functions in over 50 different countries.

    They perform quality work, and it shows through their water heaters and home appliances not only in Europe but worldwide. They create high-quality heating and air conditioning units as well as reasonably priced water heating solutions such as:

    • heat pump water heaters
    •  on-demand water heaters
    • wall-hung boilers
    •  solar thermal systems
    • so much more

    Bosch offers a wide range of on-demand or point-of-use water heaters for either residential or commercial use. Their models are cost-effective and energy efficient. Plus, depending on where you live, most of their units qualify for a federal tax credit of up to 30% of what you spent. When you factor in the high energy efficient rating Bosch carries, there’s no wonder people love this company.

    With gas tankless water heaters, Bosch creates products that are innovative and technically refined to meet all your needs. They’re always striving to create the best units on the market, and they even patented a new heat burner design that allows for added efficiency and durability.

    Comparison Table

    How Does a Tankless Water Heater Work?


    Most conventional water heaters will continuously heat water 24 hours per day and 7 days a week, no matter if you need hot water or not. Bosch’s tankless water heaters, however, are more energy efficient because they only heat the water when you need it. If you turn on a hot water tap around the shower or kitchen, for example, the water heater kicks on to deliver your needs.

    Not only does this mean these models are more energy efficient, but they will also keep your energy bill extremely low and potentially save you up to 50% on your current energy costs. For nearly half the price you pay in utilities now, you can save money long-term.

    However, the downside to saving money on your utility bill is that the upfront costs to install the water heater can be expensive. It is an investment in your future. If you buy the right water heater for your needs though, you will save money long-term.

    The tankless water heaters come in a variety of shapes and sizes, with different types as well. Some of their tankless models can also be used in solar, recirculation and space heating applications, mobile homes, or homes of all sizes. The most popular Bosch tankless water heater options include the following:

    •  Bosch C 950ES NG Greentherm
    • Bosch Therm ES 1210
    •  Bosch 940ESO NG Therm
    • Bosch 1210ES
    •  Bosch 5000 WH27 Tronic
    • Bosch 520
    •  Bosch 330 PN
    • Bosch 1050ES

    What Makes Bosch Unique?


    Bosch is an industry leader that offers the best water heating products available on the market today. Their gas water heating devices alone show how technologically advanced the company is, and Bosch has solutions for any type of customer’s needs. Their reputation stands strong.

    Prestige aside, the company can save you a ton of money on your water heating costs. Save over half your utility bill and receive a hefty tax credit back from the government when you buy a tankless water heater. They also reduce gas emissions, and with more than 90% efficiency, you can condense while saving more than ever.

    In fact, Bosch’s Greentherm 9000 series contains the industry’s highest energy efficient models available, with a factor of 0.99 and thermal efficient near 100%. The new Greentherm and Therm series models are more advanced, safer, and more reliable and durable than other water heaters out there.

    One of the coolest things about Bosch’s models is that if you find the tankless water heater isn’t performing fast enough for you, they offer tankless models that have a circulation pump built in to allow hot water to reach your tap faster.

    If the parts fail, they’re all serviceable and easy to replace. They’re convenient to use and the overall experience they provide is better than traditional water heaters found in many homes today. Although they cost more than conventional units, they were built to slash energy costs and last longer.

    Pricing Information


    Built with high-quality in mind, Bosch water heaters are built from the ground up and last around 20 years. That’s near twice the length of time many conventional water heaters last, which average around 6-12 years of use. So, these water heaters essentially pay for themselves over time.

    Most Bosch models will set you back in the upfront costs. The gas units range from the lowest prices at $$ with the Therm 830ES model to $$$ with the Greentherm 9900 WiFi model. Electric models, on the other hand, cost much less and range from around $ to $$, with the Tronic 5000C WH36 model as the most expensive option.
    With a wide range of prices from various online sellers as well, you may be able to find discounted rates from local sellers or around the web. A higher cost could reflect steep shipping costs that could add on another fifty to eighty dollars for a gas model or less or electric. Look for free shipping from online sellers to cut back costs. Westside Wholesale, for example, offers free shipping on most models.

    You can find deals easily online to save more money. ProWater Heater Supply also offers Bosch heaters on clearance, or you can easily find models on eBay or Amazon. If you want to play it safe, stick with purchasing through Bosch’s official website. Coupons and deals are everywhere, and you may be able to even find a refurbished product if you want to save an additional 10-15% on the original price.

    Keep in mind that you may also need to pay for the added water heater installation costs. A professionally licensed handyman could cost anywhere from six hundred to fifteen hundred dollars depending on your location, the professional’s pricing, and the scope of the project. Gas water heaters will typically cost more to install than electric, even though gas units typically have lower running costs.

    If you’re thinking about installing a Bosch water heater yourself, think again. The work is entirely dangerous, with the risk of shock from electrical units and explosive gas leaks or deadly carbon monoxide leaks from gas models. Bosch will also deny any warranty claims if the unit wasn’t properly installed by a licensed plumber or follows the strict specification guidelines.

    The best thing to do is hire a licensed professional to take care of the installation for you, so look for an installer that offers free quotes in your area. You may need to pay additional costs if the following installation factors affect you:

    •  Venting indoor units
    • Installation of gas line
    • Installation of piping for hot water recirculation
    •  Installation of 50-amp fuse or new electrical panel for multiple units
    • Installation of a 208/240V line
    • Bosch outdoor installation kit

    The company also offers complete customer satisfaction, and their hot water products come with a comprehensive warranty should any type of damages take place. This means you don’t need to worry about the money you’ve invested in your Bosch water heater, and you can rest assured that many other customers choose Bosch for this reason alone.

    This warranty lasts 15 years for gas models with a heat exchanger and 5 years for all general parts. Remember, Bosch will only accept warranty claims if you have a professional install the unit to ensure there are no important user mistakes.

    What the Public Thinks of Bosch Tankless Water Heaters

    bottle water

    Real customers love their Bosch water heaters. Many people say the Bosch Therm ES 1210 is the most powerful and best unit to buy from this manufacturer. Whether you are in a commercial or residential setting, it comes with an ultra-efficient gas burner and works well in large homes or when used for multiple applications. It can even take care of the needs of up to four bathrooms at the same time.

    If you’re looking for temperatures over 140 degrees Fahrenheit, the Greenthem C 1050 has the ability to reach as hot as 184 degrees Fahrenheit with its high temp kit installed. Both models are the same size that allows them to easily be mounted on the wall (even outdoors) and receive awesome customer ratings, but the Therm ES 1210 is the most energy efficient and has an Energy Star compliance.

    You can read more reviews on other top-ranked Bosch models via Tankless, a website on the world of tankless water heaters.

    How Bosch Compares to the Competition

    water in glass

    Compared to other brands like Rinnai, Takagi, Navien, or Rheem tankless water heaters, Bosch is a larger company with a large range of parts and other necessary equipment. Bosch offers all your water heating needs in one convenient location, and they focus on both gas and electric models. Instead of focusing on creating just one really good water heater, they offer a line of awesome options that set them apart.

    However, when compared to Navien and Rinnai, Bosch doesn’t offer as many high-performance or convenience features. The Greentherm and Therm series seeks to change that though with their built-in electronic control board and LCD screen display to monitor and control the temperature of your water.

    Rheem, EcoSmart, and a few other brands also offer both gas or electric models. This allows you the versatility to choose which feature you like the most and perhaps further cut back your utility costs.

    Most of these models from these brands have good ratings, ranging from mediocre to good. However, Bosch has excellent ratings all around. Some companies focus on creating one good model while Bosch works to make every unit reach perfection.

    No matter what the competitors throw out there, Bosch has a reputation as the leading supplier of heating systems for your home that no other company in the world can match.

    What We Think

    To sum up our thoughts, Bosch is an industry leader for a number of great reasons. The products they create are top of the line and come in a variety of shapes and sizes. No matter if you’re looking at gas or electric models, they have a great option to suit your every need. They’re also easy to install, maintain, and handle on a daily basis.

    But the best part about Bosch tankless water heaters is the amount of money you can save long-term. They’re entirely energy efficient and lower the energy and water consumption in any typical household or commercial business, even when you have four separate bathrooms running hot showers all at once.

    The savings don’t stop there! With the addition coupons and other deals, you can find online and the 30% tax cut, this is the most cost-effective option on the market. Sure, the upfront cost may be steeper than other options, but they’re built to last nearly double the amount of time as most water heaters. There really is no better choice.

    What To Look For In A Water Heater

    Heater meter

    You should look to invest in appliances that are energy efficient and help your home run more smoothly. The initial cost for a water heater and installation may have a significant price tag, but the cost breakdown will prove more economical in the long run if your water heater has certain features.

    Conventional models of water heater often draw on energy to keep water hot all day and night. However, if you choose a water heater that is on-demand only, tankless, or has robust insulation, you can reduce your energy costs between 50 to 70.

    A water heater that has high efficiency should enjoy a lifespan of 20 to 25 years, creates fewer emissions and energy demands, and should qualify for a tax rebate. The typical water heater that undergoes routine maintenance and frequent use has a lifespan of 8 to 12 years.

    Taking steps to upgrade an existing water heater by adding insulation around the pipes, making sure to flush it clean of sediment, and annually conducting a checkup can enhance longevity and performance.

    Consider well the needs of your household, and seek out methods to reduce water and energy consumption for the good of the planet and your pocketbook. A quality and efficient water heater from a reputable brand is best for your home.

    State Select offers five different models of high-efficiency water heaters, ranging from a 40-gallon capacity to an 80-gallon capacity.

    Types Of Water Heaters Offered By State Industries


    State Industries offers consumers electric or gas water heaters for residential use, either the Premier series or Select series. The Premier series is a bit more energy efficient than the Select series. However, the Select series offers more models.

    On average, the electric-powered tanks that are Select or Premier have a lifespan of 6 to 10 years. The Premier series offers the following features, which make it an attractive buy.

    • Ecologically-friendly gas burner
    • Automatic self-cleaning system
    • Energy Star compliance

    State Industries seeks to constantly push the envelope of innovation, as seen by their Power-Vent models, which have a 96% thermal efficiency with 129GPH recovery.

    A State Select water heater offers the following benefits.

    water bubble

    One to two heating elements using a minimum of 4500 watts each.
    A capacity of 2.5 gallons to 119-gallon tank size.
    A self-cleaning diffuser dip tube.

    Models may come in a small, medium, or tall size depending on household size and demand. Some Select models can even be installed under your kitchen sink for convenience.

    Most High-Efficiency State Select models of water heater come in a tall size and offer a 40 to 80-gallon capacity. One medium size tank is available with a 50-gallon capacity, and measure at 49 inches tall. Thanks to improvements on design, these water heaters can enjoy an extended lifespan of 10 years.

    The energy factor for efficiency models of Select water heaters is either 0.92 or 0.93, thanks to the use of heat traps, and 2.5-inch insulation with R-value.

    Additionally, to lower the incidence of a rotten egg odor, each efficiency model is outfitted with an aluminum anode rod instead of one made with magnesium.

    Electric Select water heaters are standard and come in 15 different types of models. The recovery rate is 21 F, and the energy factor ranges from a low 0.81 to 0.93.

    Table Top Select models are available only in a 26-gallon or 40-gallon model. These water heaters are unique because they have a rectangular shape and a flat top, hence the name. This type of water heater makes an excellent addition in the kitchen, as it can add to the counter space available. Table Top models have a 6-year warranty.

    Tiny houses or mobile homes require a Junior type of water heater from State Industries. The gallon capacity for Junior models range from 6-gallons to 38-gallon capacity tanks and can be installed under the kitchen sink out of sight.

    If a consumer wishes to purchase a water heater that only delivers small amounts of water, State Select offers a Point of Use model that comes in a capacity of 2.5-gallons. This model makes a good choice for an office, garage, or remote location.

    Regarding selecting a standard water heater that is under the Select series, a 40-gallon gas-powered tank is effective for most average households. This model offers many economical benefits and a low emissions rate, but it is not designated Energy Star compliant.

    This tank has a 6-year warranty, uses a 40,000 BTU gas burner, and has a recovery rate of 41 gallons for every hour. The energy factor is 0.62. This tank should fill up a tub within seven minutes and has a projected energy cost of $273.

    Other Types Of State Water Heater Models

    State Industries prides itself on offering a wide range of different models of water heaters. In addition to the Select series, there are other water heaters worth comparing.

    Tankless Models

    Tankless Models

    Tankless models of State water heaters are wall-hanging, compact, and powerful enough to accommodate a residential or small commercial space. The tankless models are suitable for both use indoors and outdoors and come with a 12-year warranty. Tankless models are available in either non-condensing or condensing.

    Hybrid Models


    State Industries provides hybrid models that are designed for thermal energy efficiency, which saves money, and encourages a faster recovery rate. Hybrid models combine the best of both features taken from tankless and tank water heaters.

    Solar Models


    A consumer can install a complete solar-powered water heater system from State Industries, consisting of a water storage tank, integrated solar pumps, and solar panels. The capacity of solar models reaches a maximum of 120 gallons and may come with backup heating elements.



    Depending on your geographical location, the price for purchasing and installing a State Industries Select series water heater may vary. You will have to contact your local plumber or retailer for a quote, which can be found via the State Industries website.

    Average reported costs for a new water heater and installation range between $1000 to $1200.

    The price you pay for your water heater should quickly pay itself forward with the warranty and customer service coverage for parts and labor in case there is a problem. Expect the monthly breakdown of maintaining and using a water heater for six years or more to show its economical value, especially if it is high efficiency.

    Public Perception


    When it comes to opinions on State Industries Select series of water heaters, there are mixed feelings all around.

    Some customers have experienced little to no problems with their installed water heaters, while others have met with varying circumstances.

    One of the biggest draws for State Industry water heaters is the fact that the warranty for part replacement is pretty good. Provided that your water heater is still covered under warranty, customer service will quickly come out and make any necessary repairs or adjustments.

    With the warranty, things can get hairy very quickly with State Industries water heaters. If you have a water heater that fails at the 5-year mark, the warranty gets transferred to a replacement model. If there are any problems, such as flooding due to a defective part, or a heating element has gone bad, you might be out of luck.

    There are some significant discrepancies when it comes to the manufacturing date for a lot of models of State Industry water heaters, which makes one question the retailer's source of water heaters installed for customers.

    It is too easy to misread the manufacturing label information. Either some people install a water heater that goes strong with no problems and minimal maintenance for 15 years, or the water heater cuts short all too soon.

    The cost of replacing parts can either be reasonable or make one question replacing the water heater with a different brand altogether.

    If anyone is looking for a cheaper option from State Industries, they may want to opt for a hybrid heat pump for hot water, and it's tankless.

    Select water heaters do stand out among the competition for being created with efficiency in mind. Certain features of the water heaters are applicable for LEED construction. The use of vents helps minimize heat loss, as well as foam insulation, heat traps, and glass lined tanks.

    Be forewarned, you may either get great customer service with no unexplainable extra charges, or you might suffer the dilemma of having the parts covered under warranty, but not labor.

    What We Think

    If you care about supporting an American-based company that has been in the business of creating water heaters and other products for decades, choose State for your water heater.

    However, there have been a lot of negative things to say about State Industries water heaters, which may have something to do with the retailer or plumbing service responsible for sale and installation, and not the actual product itself.

    Some customers have complained that their water heater died on them after reaching the 4 or 5-year mark, with only a handful saying positive things.

    It is good that there is still ins American-made water heater company providing a wide range of heaters that use eco-friendly energy sources to power up, or are made for thermal efficiency and improved recovery rates.

    State Industries does offer water heaters that are solar-powered, create low emissions, or are applicable to smaller residential and commercial spaces for both indoor or outdoor.

    If you don't mind utilizing the services of your local plumber to get a quote for installing a State Industries water heater, and you think your product will make it to 6-years under warranty without failure, give it a chance.

    There are other water heaters available, where there is more transparency about prices, and with longer lifespans beyond the 6-year mark. The Select series of water heaters from State Industries seems impressive on the surface, but there are too many negative reviews to fully endorse grabbing this brand of water heater with 100% confidence.

    Consider your options before you make a final decision on a brand of water heater. Sadly, State Industries, despite its boasted commitment to innovation and developing better more efficient water heaters fails to meet the hype.

    There are too many problems with faulty heaters that break down or suffer leaks within as little as 2 to 3 years, which is significantly less than a 10 to 12-year lifespan or longer. If a customer is going to be stuck constantly needing to replace their water heater, or paying for repairs, then any energy efficiency is going to go down.

    Unless you have a small space or have unique needs for an atypical water heater, you will want to pass on State Industries for a different brand.

    Customers can expect to spend more than they bargained for when labor and parts are needed, or they have to shell out for a completely new water heater. State Industries is providing products that are a gamble. Clogging and pilot light outages are a huge issue.

    Coupons And Deals

    There are no coupons or deals available for State water heaters. Customers can only purchase and get a water heater from State Industries installed after contacting an established plumber, and prices are subject to vary.

    GE Water Heater Reviews

    GE go spring
    GE geh50deedsr

    GE Appliances has a small line of hybrid water heaters. These appliances use a heat pump and heating elements to heat water in an energy-efficient manner. Here is what you need to know about getting a GE water heater.

    GE Appliances is known for making energy-efficient appliances, including fridges, washers, and more. The brand also has a line of water heaters. This brand is an excellent choice if you are looking for a hybrid appliance designed to help you reduce your bills and environmental footprint. Here is what you need to know about getting a GE water heater.

    What Is A GE Water Heater And How Is It Different From Other Appliances?

    GE Appliances recently replaced its entire line of water heaters with two versions of a hybrid model. The brand used to offer electric and natural gas appliances and some retailers still have some of these water heaters in stock.

    Shower Filters from FilterWater.com

    The older GE Appliances water heaters are worth considering if you want a traditional electric or natural gas appliance. These appliances are energy-efficient and built to last.

    However, the new addition to the water heater line is a better option if you want to reduce your energy use. GE Appliances offers two versions of the same hybrid water heater. One version has a 50-gallon tank while the other option has a capacity of 80 gallons.

    This hybrid water heater is an Energy Star certified appliance. It uses a heat pump to use the ambient temperature of the air to heat water.

    The installation is similar to an electric appliance. This means you can use existing hookups if your old water heater was an electric appliance. There are no significant costs associated with installing this appliance.

    This is a water heater worth considering if you want to reduce your bills and environmental footprint since it is on average 70 percent more efficient than a standard electric water heater.

    The first-hour delivery of this appliance is 69 gallons. This means that if you were to fill up the tank with cold water and let the appliance run for an hour, the water heater would deliver 69 gallons of hot water. This rating gives you an idea of how quickly the tank replenishes when you use hot water.

    A high first-hour delivery rate is important if you have a large family or are likely to run appliances such as a dishwasher or washing machine while taking a shower. The 50-gallon model is suitable for the needs of a household of three or four people while the 80-gallon model is a better choice if you have a household of five people or more.

    The uniform energy factor of this hybrid water heater is 3.25. The uniform energy factor is a rating that gives you an idea of how much energy an appliance uses.

    It is based on cycling and standby losses and recovery efficiency. This rating gives you an idea of how efficiently an appliance will generate hot water during a day of typical use.

    You can compare uniform energy factors between different appliances. The water heater with the highest energy factor will be the most energy-efficient one.

    You can use the uniform energy factor of a water heater to calculate the annual operating cost. Multiply 365 days by 12.03 kWh/day and divide the result by the number you obtain when you multiple the uniform energy factor of a water heater with the fuel cost in dollars per kWh. You should be able to find the cost of electric per kWh in your area by checking your bill.

    The heat pump is the standout feature of this water heater. It is more energy-efficient than the heating elements you will find in traditional electric water heaters. GE Appliances’ hybrid water heater combines this heat pump with two electric elements.

    You can choose from four operating modes and a vacation mode. The GE water heater features an LCD control panel so you can easily switch between modes or adjust the temperature.

    These controls allow you to choose the mode that is adapted to your needs and will contribute to the energy savings. These are the different modes you can choose from:

    • Heat pump mode only. This mode uses the heat pump to keep water hot and saves energy.
    • Hybrid mode. This mode primarily relies on the heat pump but will fall back on the heating elements to boost the recovery rate.
    • High demand mode. This mode is similar to the hybrid mode but features a more performing recovery rate. This is ideal for large families.
    • Electric mode. This mode relies entirely on the heating elements. It is recommended if you can’t use the heat pump due to low ambient temperature.
    • Vacation mode. This mode will maintain water at 50°F to keep it from freezing. You can set a time and date and have the water heater automatically reset when you come back from vacation.

    The hybrid water heater is Wi-Fi compatible. You can use a home automation app to control temperature settings or change modes, or simply use your phone to remotely adjust these settings.

    What Makes The GE Water Heater Unique?

    GE GEH50DEEDSR GeoSpring Hybrid Electric Water Heater

    The heat pump is what makes this appliance unique. This part uses heat from the ambient air to heat water. This technology uses far less energy compared to heating elements or burners. GE Appliances claims that the water heater is 62 percent more efficient than a traditional electric water heater.

    It is easier to maintain water at the desired temperature if the ambient air is warm. Savings are going to vary based on your area and climate.

    Being able to choose between four different modes is an interesting feature. You can select the option that is adapted to the needs of your family, and benefit from the heating elements if the temperature of the ambient air drops during the winter.

    The hybrid technology helps you save money and energy without impacting the recovery rate of your water heater thanks to these different modes.

    Choosing the heat pump only mode or hybrid mode will help reduce your environmental footprint. These modes will be sufficient for the needs of your family if you have a small household or make a conscious effort not to run appliances that use hot water while taking a shower.

    According to GE Appliances, you can save $160 to $330 a year with the 50-gallon tank water heater depending on the size of your family. You should be able to save at least $400 a year with the 80-gallon model.

    The water heater comes with a 10-year warranty for the appliance and a one-year warranty on labor.

    The brand has an excellent reputation and is known for making quality appliances. The fact that it has replaced its entire line of water heaters with these hybrid appliances speaks volumes about how energy-efficient and reliable the technology is.


    The 50-gallon hybrid water heater costs around $900. If you are interested in the 80-gallon model, you will have to spend around $1,100.

    Keep in mind that there might be additional installation costs if you have a professional install your new water heater.

    Public Perception

    The GE Appliances website has published several reviews from shoppers. The average rating is 4.7 out of 5 stars and most shoppers have selected the five-star rating.

    However, the water heater has lower ratings on Amazon. The 50-gallon model has a rating of 3 out of 5 stars on one product page and 3.3 out of 5 stars on another.

    The positive reviews talk about the water heater being reliable and energy-efficient. Shoppers talk about saving money and like the hybrid mode since it provides them with the hot water they need while reducing their bills.

    Some people also say that the appliance helps reduce humidity in the air and keeps their garage cool. They like the easy installation process and quiet operation.

    Some shoppers have written mixed or negative reviews because of leaks or faulty parts. The heat pump seems to create condensation that needs to be drained to prevent leaks.

    There are a few tweaks needed, such as installing a vacuum relief valve or dehumidifying pump to address this issue. Installing the appliance in an environment with a stable ambient temperature seems to prevent problems.

    How It Compares To Other Water Heaters

    There are other water heaters with similar energy-efficient technologies that are worth considering.

    This 50-gallon water heater uses two copper heating elements and a heat pump. It is an Energy Star-certified appliance and is 72 percent more efficient than a traditional electric water heater.

    The manufacturer says that annual operation costs can be as low as $114. This amount will vary depending on the size of your household and your needs.

    This appliance features four modes and has an interface that is similar to the hybrid water heater made by GE Appliances. The interface can diagnose problems and display error messages.

    The four modes include an efficiency, hybrid, electric, and vacation mode. This is similar to the features of the GE Appliances water heater other than the high demand mode being missing.

    This water heater comes with a 10-year warranty and has a recovery rate of 20.7 gallons in the first-hour. The uniform energy factor is 3.42, which is slightly more efficient than the hybrid water heater from GE.

    This water heater is compatible with the Energy Star Iris module. This is a connected controller that lets you control settings remotely and build routines in a home automation app.

    Rheem Performance Platinum 65 gal. 10 Year Hybrid High Efficiency Smart Tank Electric Water Heater

    Rheem Performance Platinum

    This water heater is pricier but represents an excellent investment. It uses a heat pump and heating elements.

    You can choose between three different models with tank capacities of 50, 65, and 80 gallons. The 65-gallon model is worth considering if the two sizes offered by GE Appliances don’t seem like good matches for your household.

    This appliance has a uniform energy factor of 3.70, which makes it more efficient than the GE water heater. It has an Energy Star certification and a 10-year warranty.

    The first-hour delivery rate is 72 gallons. You can select an energy saver and vacation mode, but this appliance has fewer modes and settings compared to the GE Appliances hybrid water heater.

    The Wi-Fi connection feature stands out. The water heater can send alerts to your phone when a leak is detected and will also send you maintenance reminders.

    Triangle Tube 36 gal. Indirect Hybrid Electric Water Heater

    triangle tube residential hybrid water heaters smart

    This energy-efficient water heater uses a different technology. It features two stainless steel tanks. The outside tank houses a smaller tank and is filled with boiler water that heats the water inside of the smaller tank.

    Heating water from the outside is more efficient compared to heating elements. This design requires very little maintenance and is an interesting alternative if you live in an area with low temperatures.

    The first-hour recovery rate is 180 gallons. You can use this 36-gallon water heater to meet the needs of a household of three or four people due to this high efficiency.

    Because there are no moving parts, this water heater can last as long as twenty years. There are other water heaters to look at if you want different modes or connectivity features, but this small water heater is an excellent investment if you want a durable appliance with a great recovery rate.

    What We Think

    How To Find The Best Water Heater

    A water heater should last between eight and 12 years. It is important to do some research before buying a new appliance since choosing a water heater adapted to your needs will help keep your energy bills down.

    Tank Capacity

    The size of the tank impacts the initial price of purchase as well as how much energy the water heater will use to keep water at a specific temperature. You need to assess the needs of your family to determine which tank capacity is best.

    Water heater tanks typically range from 20 to 80 gallons. You can install a small tank in a closet while a larger tank will only fit in a basement. The location of the existing hookups for your water heater might limit your options.

    If you live alone or in a home with two people, the best water heater for your needs will have a tank capacity of 20 to 36 gallons. An appliance with a tank of 36 to 46 gallons is recommended for a household of two to four people.

    A 50-gallon water heater is a good choice for a household or three to five people. You will need to explore appliance with a tank capacity that is somewhere between 56 and 80 gallons if there are more than five people in your home.

    Recovery Rate

    The recovery rate of a water heater is expressed in gallons per hour. This rating indicates how quickly the appliance can raise the temperature of the water by 90°F.

    A water heater with a low recovery rate might not sustain your need for hot water if you take a shower while using an appliance such as a dishwasher. You might also have to wait for the tank to warm up the water again once you are done taking a shower.

    Tankless Water Heaters

    Tankless water heaters tend to have a higher initial cost. They are more compact and can usually be attached to a wall near the point of use. They need to be installed in a well-ventilated area.

    If you want to get a tankless water heater, look at the flow rate and maximum temperature rise. A bathroom faucet requires a flow rate of at least 1.5 gallons per minute while a shower requires 2.5 to three gallons per minute.

    If you want to take a shower while you wash a load of laundry, you will need a water heater with a flow rate of at least five gallons per minute. Living in a cold state means you will have to invest in a more performing tankless appliance since you will need a better temperature rise performance.

    Fuel Type And Energy Efficiency

    Natural gas and propane water heaters require ventilation. Installation one of these appliances might not be a viable option if you don’t have the proper hookups or can’t use a well-ventilated area.

    You can generate enough hot water for your household with a smaller tank capacity if you choose a natural gas or propane water heater. For instance, you can meet the needs of three to four people with a 50-gallon electric water heater but would only need a 40-gallon natural gas appliance for the same household.

    However, natural gas and propane tend to be more affordable than electric appliances. These water heaters are usually more performing, which means you will save money on your energy bills.

    Electric water heaters tend to have a lower initial purchase price. You can find performing and energy-efficient appliances if you shop around, and repairs are typically more affordable.

    These tips and recommendations will help you find the best water heater for your needs. Remember to compare the features and specs of different appliances and to look at the annual operating cost besides comparing the initial purchase price.
