Stiebel Eltron Tempra 15 TrendElectric Tankless Water Heater

The Stiebel Eltron Tempra 15 Trend electric tankless water heater is popular in Canada for low flow or point of use applications where high flow rates are not required. With 14.4 KW of heating power it provides endless hot water at low flow rates even in our Northern climate.

The Tempra 15 Trend features Stiebel Eltrons true microprocessor-controlled temperature regulation and full power modulation based on both incoming water temperature and flow rate required. This means the Tempra 15 Trend will measure the flow rate of whatever applications you have turned on, determine the incoming water temperature, and apply the appropriate amount of power to heat the water to the temperature you have set it to. A dial on the front of the unit allows you to set the output water temperature anywhere between 30°C and 60°C. The Tempra series of electric tankless water heaters are one of only a few tankless water heaters available today that feature a true thermostatic temperature and full power-modulation experience. This means no fluctuating water temperatures.

The Stiebel Eltron Tempra Series electric tankless water heaters feature the most precise temperature control of any tankless water heater on the market today!

Steibel 15
Installed the unit according to the directions and it did not work at first. I think because the water pressure needed time to reach normal in the unit. It now works fine to heat our master bath fixtures - Stephen K

E Tankless Water Heater
Love it, works great & company very helpful when ordering. - Janice

Great heater
When my home was built 25 years ago, this was the hot water heater. You might be thinking that a hot water heater should justifiably last an easy 25 years. I have well water, and 1 filter before the heater. This statement says more. I absolutely had to get the same one. It is a little taller so a tiny bit of plumbing and tada, easy to install. I am pretty old fashioned so the extra options are not important to me, but all I did was set it to 110 degrees with the dial, done. In 25 years I will get another if it is needed. I had a GE tank break after 2 years and the insurance stuck it to me. Personally I am so very sick of garbage on the market. This unit in my home has a proven track record and I am all about proof. - Steve A

stiebel eletron tempra 15 trend tankless water heater
Heater is working flawlessly. Excellent quality. Very good instructions for installing heater. The unit is for one full bathroom (tub and sink). I live in southern Maryland and the water heater keeps the water a constant 115 degrees at 2.8GPM with no issues. Thanks - Vincent Beatrez

Finally we have UNLIMITED Hot Water, Thank you e-tankless!
Our water heater is in the garage and our Master Bath is on the other side of the house. We have a Taco recirc pump but our 66 gallon water heater tank couldn't provide enough hot water for long relaxing showers. We bought the 29B (refurb) from e-Tankless. It looked brand new, came in the original packaging. It was fairly expensive ($2,100 USD) to run new 125A service to support this water heater but I am so glad we did. We now have endless hot water! I would recommend buying the isolation valve kit so you can easily flush the unit annually. I would highly recommend e-tankless! - Todd Simmons

Worth it
My old waterheater was in my attic which daily made me nervous to have 50 gallons that could leak at any time. I upgraded to tankless and I am very impressed the hot water works better much better now. - Shawn Lawson
