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. Tempra Plus models incorporate Advanced Flow Control that automatically reduces flow to deliver water at the set point if demand exceeds capacity. Regular Tempra models do not have this feature.

I used the area maps and usage diagrams to figure out which heater to purchase. Knowing I had 100 amp service this was the largest unit I could install in a seasonal house with one set of kitchen faucets, bathroom faucets, and one shower/tub. Installation was quite straight forward and went well.Usually one set of faucets would be used at a time, so I expected the unit to perform well. However, it didn't work very well with any one source of water usage turned fully on. Apparently the water flow was too much for the heater to keep up with. I closed the valve partially on the incoming water to reduce the flow to see if I got better results. It helped a tiny bit. Next by reducing the outflow when trying each different faucet system I was able to get a steady red light and constant 120 degree hot water from the heater. I think the problem is my water coming from my well is colder than the 42 degrees shown the map covering the state of Maine and the flow rate is too strong. In hindsight, If I could have afforded it, perhaps the Tempra 15 Plus might have worked better.

Rated 1 out of 5 by from Be extremely careful before buying. This device will not provide hot water for a tub in Canada or north of the Mason-Dixon Line. The sizing guide did not indicate anything about a tub (high flow device) not getting hot water. I put this in a cottage and the tub will not get anything but tepid water.

Rated 5 out of 5 by from Very Good Product Adjustable Temp. on front easy to use. I love It, Saves on my electric bill. Plenty Hot. I had a power star that was all that was available 5years + ago never did work right. I did my research this time and found this. It is what I should have had from the start. Fantastic Product. These do take a plumber and electrition to hook up. My house was built with hookups and special electrical in mind running these units is 220 with Two 40 amp connections. Farther North you will need the more amp units. But these are well worth the investment and they take up very little space. Hook up took about an hour, electrition plumber highly recommended.

what are the electrical panel requirements for this unit? how much would it cost to have it installed?

Asked by: Nadene17
You must have a 125AMP servi e coming into your home. If you have that an electrician can intal the two 40amp breaks.
