Stiebel Eltron Tempra 36 TrendElectric Tankless Water Heater

The 36KW Stiebel Eltron Tempra 36 Trend is one of the most powerful electric tankless water heaters on the market. It was designed primarily for higher flow rate applications in cold climates like ours where the incoming water temperatures can drop below 5°C or for commercial applications.

The Tempra 36 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 36 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 Trend Series electric tankless water heaters feature the most precise temperature control of any tankless water heater on the market today!

Some codes require use of electrical sub-panel for installation, especially when heater is not mounted within line-of-sight of the main electrical panel. Wiring should be sized to maintain a voltage drop of less than 3% under load. Please consult your electrician for more details.

Stiebel Eltron Tempra 36 Trend Reviews

Excellent solution for on demand hot water
This purchase is a replacement for the previous model of the same specs we had installed in our condo about 15 years ago. The electrical elements do wear out in about 15 years, so we installed a replacement unit. The new unit is smaller and has a better screen than the old one. It works wonderfully, and we are just as happy with this one as we were with its predecessot. -

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

Tankless
Tankless So far it’s working great. If it goes well I will order four more for my other units - Mario Tridente

Owner
excellent product. easy to operate, user friendly - Chep Hon

Replacing on older Steibel Eltron unit
After about 15 years of faithful service my older model Steibel Ultron tankless water heater stopped heating the water effectively (lime scale). This new unit (Tempra 29) is the newest edition of the prior model. No issues installing although the size and spacing of the water inlets/outlets differed meaning a little extra work. New unit works like a charm now - Jeff
