Powerful output, compact design, and remarkable energy-savings. Tempra Plus models feature Advanced Flow Control, patented in Germany and exclusive to Stiebel Eltron tankless heaters, that automatically maintains desired hot water temperature by slightly reducing flow when necessary. Self-modulating technology ensures the least amount of energy is used to heat the water. A Tempra 29 Plus provides hot water at a constant temperature for up to 3 bathrooms in warm climates, or 2 or 3 bathrooms in cool climates. See sizing guide to determine the best model for you. 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 our products to perform at the highest standards of comfort and reliability.

My home is 1700sq ft, with clothes washer, dish washer, 1 shower, 1 tub/shower, 4 BR sinks, one kitchen sink, and it operates perfectly. It takes a minute to get hot for the BR sinks, but once hot water is flowing it's perfect. We'll see as the family gets older, and demand increases, but I recommend it highly.

Takes a few seconds longer to get hot water than a hot water tank but we love the idea of not having to worry about water tank leaks anymore. No real savings in water or electricity noticed but it's still early.

The overview on this unit mentions 60 amp breakers in bullet one and 40 amp breakers in bullet 3. I’m confused now to the exact requirements snd wiring needed to install this when I order it. Rick

Asked by: Rick
3 40 amp breakers. If you call customer service they are very helpful. I ran into problems also when installing   Manual is a bit confusing

Does this unit have to be flushed with vinegar or other chemical on a yearly basis like the tankless gas water heaters? Is it possible to put a whole-house water filter which would make this flushing unnecessary?
Asked by: iwonder
Yes, if you have mineral in the water, you need to clean it with a descaling agent. Flow-Aide is a great product to use to do this. You can also use a whole house filter (stay away from a salt filter) too.

Asked by: Johnny
Tempra models typically are used for domestic hot water. You can use them for radiant floor but we would suggest calling our Technical Support Department at 1-800-582-8423 Ext 26 for some advice in sizing a unit for the square footage you have. Thank you.
