Stiebel Eltron has been a world leader in advanced water heating technology for almost 90 years. Our engineering excellence and high-quality manufacturing results in products fulfilling the highest expectations of performance & reliability. Tempra Series whole house tankless electric water heaters are 99% efficient and never waste energy storing hot water, but endlessly deliver it as needed. Tempras need no venting. Installation can be close to draw off points, making the wait for hot water as short as possible & maximizing energy savings. Tempras are sized based on the number of bathrooms. Tempras supply water at a constant temperature from 86 to 140 degrees F that is settable on the front panel. We recommend setting the actual highest temperature you use, typically 107 degrees for a shower.

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.

Also, set starting water temperature low, like 109, to prevent thermostats from cycling off and on. Causing shower water going from hot to cold, back and forth.

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.

I live in Milton, Ontario approximately 3000 sqft, 4 bath home running on well water, does anyone have this unit or similar one and how does it work any complaints, any energy savings?

Asked by: Dan2097
This would be the unit most commonly suggested for a home like this. We would also suggest having your well water tested for minerals to ensure the correct filter is installed if any are found in the water quality report.

What is the minimum flow rate required for the heater to kick in? Also what is the peak GPM that I can expect with a 5 degree Celsius cold water source?

Asked by: Mike
The Tempra 29 Plus requires a flow rate of .77 GPM to activate the unit. We try to suggest setting these units so you have a final output of about 110 degrees F (44 degrees C). With a 41 degree F inlet temperature (5 C) you should get about 3 GPM (Gallons Per Minute) from this heater. Please feel free to call our Technical Support Department at 1-800-582-8423 ext 6 with any questions. Thank You.

How many gpm does this heat?

Asked by: Bsplicer
The final GPM output depends on the incoming water temperature. In colder climates, this unit would range about 3 - 4 GPM, in warmer climates this unit would range around 5 - 6 GPM Please feel free to contact our Technical Department at 1-800-582-8423 ext 6 with any further questions. Thank You.
