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. Intelligent self-modulating technology continually ensures the least amount of energy is used to heat the water. 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.

Everyone talks about how great ths water heater is but no one has mentioned how much electricity it uses. so hpw much will this unit use?

Asked by: Skippypa
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 automatically to the lowest amount needed in order to heat the water being drawn with the least amount of electricity.

Single or double pole breakers???

I understand that this takes three 50AMP breakers but does those breakers have to be double pole or can you use single pole? Trying to save some space in my panel, so if single pole 50 AMP breakers would work that would be great. Thanks for your input.
Asked by: GuyinVA
50 Amp double breakers are required because this unit operates on 240V (each one of the 50A breakers must be 240V). Single pole breakers only give you 120V. To save space, most likely your panel is able to use tandem breakers. If this is the case you can replace multiples of your 15 and/or 20 amp single breakers with 15 or 20 amp tandem breakers (2 breakers in a single 1" space), gaining a single space each time. If you had no space left in your panel you would need a total of 6 tandem breakers (in any combination that replaces your existing single breakers) to gain enough open space for the 3 50 amp double pole breakers needed.

Tempra 36 Plus Advanced Flow Control and Self-Modulating 36 kW 7.03 GPM Electric Tankless Water Heater is rated 4.9 out of 5 by 17.
Rated 5 out of 5 by from 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. We would always run out of hot water and it was never that hot. We now have an endless supply of piping hot water on demand. Love it.

However I will recommend self - install unless you have experience in electrical wiring and plumbing. The unit is easy to setup and operate. The weekend after installing the Tempra 36 Plus, we had house guess and with 3 bath room, everyone had plenty of hot water. The Tempra 36 Plus is worth the investment of time and money.

Rated 5 out of 5 by from Be sure this is the unit you really need! This product works as advertised and is extremely well designed and well made, but may not be what you need. You need to determine how many amps your house is wired for, as this unit will need 150 amps when it draws at maximum (which is only briefly on start-up and at maximum flow). This means your house needs at least 300 amp service and most houses are wired for only 200 amps. Also the published 7 gpm flow rate is based (as is the case with all tankless water heaters regardless of manufacturer) on heating the incoming water only 35 degrees. Only southern Florida & Texas and the desert areas of the Southwest need that little heat input to get hot water. If you are anywhere else in the US, you will not achieve that flow rate as the water heater will need to add more heat to get your water up to temperature. And most people actually don’t need that kind of flow rate. Check the sizing guide or flow rate chart to make sure this model is the one that will do what you need. You actually might be better off with one of their smaller models.

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from Happy user Had ours for about a year now. Installation was not that difficult. However, did call in an electrician to complete the installation. Make sure you check to see if you have room in your circuit box for the three 50 amp breaks it needs. Had to move one of my breaks to keep these in line together. Unit works as advertised . There is plenty of hot water through out the house. Took us a couple of weeks to adjust the hot water temp to get the right water mix when multiple devices are used at once. Inlet water temp makes a big difference. We have our own well with a storage tank. Because of the storage tank the water in the winter is much colder. Still have plenty of hot water, but can only run one shower at a time in the winter. With that said this still is an excellent product. Nice to gain the space in garage used by the old hot water tank. Don't expect a big savings on your electric bill. It took a couple of months to see the difference.
