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.

We have had this unit only 1.5 years and the flow sensor has already gone bad. I called the company and they refuse to overnight me one unless I pay. This is unacceptable for an $800 unit that has only lasted 1.5 years. So now I have to wait 3-5 days without hot water until this replacement "flow sensor" arrives. Save yourself the headache and just buy a regular tank water heater instead. Some things shouldn't be reinvented. I will never buy a Stiebel Eltron unit again due to their unreliable nature and more importantly how I was treated by their customer service department.

One in our home and one in my parent's home. We also have a smaller unit in our home in the kitchen. We installed them ourselves. We like the way they work. Excellent choice! Works great!

Like any on demand system, this unit does have a longer lag time to get hot water to a tap than a continuously heated hot water system (tank). I cannot wait to see the saving only energy bill.

I had another electric instant water heater installed and it failed twice costing expensive repairs. I decided to purchase this unit and over the past year it has performed perfect. Highly recommend the unit.

I have to wait 2 mins 45 secs for the hot water to get to my kitchen sink. Can I use one of these to heat the water until the regular hot water gets there?
Asked by: meaty
You could use this unit closer to the sink which will reduce your hot water wait time. Once the hot water reaches this electric heater, the electric heater shuts off based on a temperature you choose. However, this is a large unit for just a kitchen sink. I use it for my whole house when my tank heater runs out of hot water.

if I have a 200amp box, can I run a Tempra 27 off of it? I have a walking in tub that hold about 55 gallons of water, which makes me need a lot of hot water fast.
Asked by: Saintroch33
Yes, a 200 amp service is more than adequate to provide power to this unit. My service is 200 amp and I have a three other 240 outlets and I have never had a problem.
