Product Overview

Powerful output, compact design, remarkable energy-saving features: Our whole house electric tankless water heaters perform with the highest standards for comfort and reliability. Tempra Plus models feature Advanced Flow Control, exclusive to Stiebel Eltron tankless heaters. If hot water demand exceeds unit’s working capacity, Advanced Flow Control automatically maintains consistent temperatures by slightly reducing flow.

The Tempra 36 Plus provides hot water at a consistent temperature for 3-4 bathrooms in warm climates, or 2-3 bathrooms in cool climates. See sizing guide to determine which model is best for you (guide assumes 2 GPM or less per shower-head). Stiebel Eltron invented tankless electric water heating technology more than 90 years ago, and is still the industry pioneer and world leader. Our engineering and manufacturing tradition of excellence means you can depend on the performance and reliability of our products. Call Stiebel Eltron at 800-582-8423 if you have high flow showers or any sizing questions.

Answer: 
U.S. homes are supplied with voltages that are approximately 115 volt and 230 volt, but the actual voltage may vary on either side of that as much as 10 volts. These voltages are usually referred to as 110 & 220 volt or 120 & 240 volt. This machine needs to be connected to the higher voltage supplied to your house no matter what it's called.

Answer: 
The Tempra 36 Plus requires 3 separate 240 V circuits, like the single ones you might have on an electric clothes dryer or an electric cooking range. Each circuit can draw max 50 amps for a total of 150 amp max. This unit therefore requires a min 300 amp service to support it. There is no changing this requirement.

Answer: 
Overall this water heater heater will use about 15-20% less electricity than an electric tank water heater. But since it is heating water as you use it rather than storing it, it needs more power to work than a tank. At full power a Tempra 36 will draw 150 amps. This amount of power is only needed when the unit is run at maximum capacity. It has auto-modulation which will reduce the amount of power draw Read More

Answer: 
If you have an electric tank-type now this unit will save you about 20% on the hot water heating portion of your electric bill, assuming a similar amount of use. When it is not on, it is not drawing any power. However, it requires 3 separate 240 V circuits, each drawing a max 50 amps for a total of 150 amps. Much of the time it will modulate and draw somewhat less amps, but you need to size for the max Read More

Answer: 
The short answer is it depends on how much hot water you use. But... in general the answer to how much total electricity is it will use about 15-20% less electricity than a standard electric tank because there are no standby losses. If the question is about the total 150 amp draw, then the answer is the 150 amp draw only occurs when the unit first turns on and then is putting out maximum hot water. If Read More

If only a little hot water is needed, it draws a lot less electricity, only enough to heat the water you need as hot as you need it. The gas tankless guys call this "modulation." Read Less

Rated 5.0 out of 5.0 by Should have Purchased and Installed this Product years ago This product is very compact and freed up a very tight space where the water heater used to be.

Rated 5.0 out of 5.0 by Excellent Product for Us I was a bit pessimistic when we purchased this product but it proved me wrong. This is an excellent product, I'm glad we made his choice. We have a 3-bathroom, 2-story home and this product works great. Remember to use the correct voltage requirements and you won't go wrong. It's worth it ! January 14, 2014
Rated 5.0 out of 5.0 by Great I have three bathroom and the system is working great. I would recommend. The electric installation is the only issue that I had, you have to hire a electrician to get the new breakers installed. January 19, 2016

Rated 5.0 out of 5.0 by Love, love, love it! We have hot water within a few seconds, and the water stays hot no matter how many showers are in use. We had an electrician and plumber install it. We had to contact the tech support of Siebert-Elton because the water was taking a long time to get hot and would not stay hot. Tech support had us flush the water lines to remove any gunk/blockage which solved the problem. We have had hot water ever since. Great product! December 10, 2014
