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.

Customer Questions & Answers

i need it to be a 110 or 210 volt this is what we have in the U.S

Asked by: pat
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.

How many years is this water heater going to last? Will it eventually have to be replaced?

How many years is this water heater going to last? Will it eventually have to be replaced?
Asked by: Fish

Does this restrict the water flow at all?

Or do you get the same water pressure as without it?
Asked by: BeenthereDonethatDonethat
No but the water temperature will be maintained only if you don't exceed the maximum GPM.

This 5.46GPM, does this output be good for how many hours. Is this heater good to use with commercial washing machine?

Asked by: ray
As long as the water is flowing through the unit above the activation rate this heater will heat water to the set point. This could be for 10 seconds, 10 hours, or even 10 days straight. Don't forget that 5.46 gpm is at a 45 degree temperature rise so make sure the temperature rise you need will still give you the gpm you need. Also I'd suggest discussing your on cycle with your electrician. The current breaker recommendation is for non-continuous use and it sounds like you will exceed that standard and need breakers and wires sized for continuous load.

How big a unit I need is confusing.

I need a unit to handle a large house with an in-law suite. The house has a total of 3 baths without tubs, showers only, 3 single bathroom sinks, 2 kitchen sinks, 2 dishwashers, and 1 efficient, low water, front load washer. Two of the baths, 1 kitchen with sink and dishwasher, and the clothes washer are all upstairs. Do I need more then one unit? I live in NE Pennsylvania.

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.

Is everything electric or do I need a gas or prone line?

Asked by: Cholo
You do not need any gas or propane at all. Everything is electric. You will need at least 300 amp service to the house as this unit requires 150 amps just for itself. It does not pull that much power all the time but must have it available for maximum demand situations.

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 16.
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.

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.

Rated 5 out of 5 by from Easy to use and install! The hardest thing about installing this product was figuring where I wanted to mount it. It was easy to install and even easier to set up. I ran 4 sinks, 2 tub/showers and a washing machine simultaneously and it kept up.
