Thankfully the Stiebel Eltron Tempra Plus is a silent runner, so quiet in fact that you may even forget that it’s there. What makes it so smooth?

The unit itself is only measured out at 9 x 4 x 13” which doesn’t occupy much space and would be perfect for smaller homes or studio apartments. While the unit is supplied by electricity, which isn’t the most inexpensive fuel source, it was the most convenient way to make this unit function, and you don’t have to worry about gas pipes or ventilation which costs more to install.

You’re allowed to set your temperature by merely twisting the single knob positioned on the front panel of the device. You’ll have an LED display that shows you at what temperature you’re sitting at ( In Fahrenheit) to guarantee the temperature you want.
Unfortunately, there is one major flaw concerning the RTEX, and that is that if you have a larger household where two or more people want to take a shower at the same time, the unit won't be able to keep up and you’ll run out of hot water. Despite this flaw, it seems that most individuals who purchased this model of water heater were thrilled with their purchase.

Despite the stigma about extra costs associated with installing proper ventilation for a natural gas water heater, this brand manages to break through that barrier by providing two venting options already pre-built into the system. You’ll have the choice of either concentric-PVC or twin piping to use depending on which one is easier to install.
Unlike many models of tankless water heaters, the Rinnai is a workhorse in comparison. The Rinnai is capable of taking on a flow rate of 9.8 GPM which means larger households would benefit significantly from purchasing this model.

The only problems that consumers seemed to have with this model of water heater are the fact that for one, it was bulkier than most current models on the market and it was more challenging to install. That said, it’s size is still a significant difference compared to a traditional water heater so you’ll still be able to take advantage of the new space you’ll get.
As for the difficulty in installation, you’ll likely have to hire someone to get the job done. While that can cost a bit up front, it will be an investment worth having.

Another great feature that Bosch has implemented into this system is that you can achieve installation in two different ways. It could be connected directly into your electrical system, or it can plug directly into an outlet. The Bosch Tronic requires 120 volts of power to run, however, so make sure that your area can support its energy needs.
The front panel has the temperature controls installed on it; a simple dial will be all you need to either set the temperature to a minimum or maximum level. This dial is also how you turn off the unit.
Unfortunately, many customers weren’t pleased that there wasn’t a digital readout to know what the temperature of the water would be, however, the price makes it worth the simplistic design. If this little tankless water heater is everything you’ve been looking for, you can find it on Amazon.
When it comes to deciding on your tankless water heater choice, check installation requirements and make sure that if you can’t install the unit yourself, then you’ll have the funds to hire a professional.
