Rated 3.0 out of 5.0 by Steve Haven't had it long enough to give the great review I'm hopping to give.
Tempaputre dial: being able to just walk over and turn the dial to the water temp I want is great. I'm waiting to see the electric bill.

Rated 4.0 out of 5.0 by MES So far so good
I have had a few months now. This replaced a 50 gal tank. Electrician needed to install sub panel, add breakers, run wiring, and upsize home main breaker to 200amps. Did the plumbing myself. Flow is fine even in tub. Slight fluctuation in temperature when my boyfriend uses another fixture simultaneously, despite the claim to maintain constant temp. That is the reason for 4 stars. Still, awesome to not run out of hot water and I'm saving money on electric bills- $20-30 per mo.

Rated 5.0 out of 5.0 by RLS Best of tankless water heaters
Very easy to operate. Had to add another electric panel to accommodate the three 40-watt load from the heater.

Rated 5.0 out of 5.0 by Pats12 Electric Tankless Water Heater Stiebel Eltron
Great product, now for the nuts and bolts. Lets make sure one knows the reason for a tankless. 1) space 2) save money 3) the need for endless hot water. Now lets make sure one knows what it is NOT. Tankless is not instant hot water. For the record it takes longer to get to your faucet or tub than a tank unit. Why b/c of no reservoir and in order to make hot water the unit has to sense flow and how much flow.On electric you have flow determines the amount of current or scales the current back and forth. Gas units the burner uses more gas or less by flow of water. My electric Tempra 29 plus I had to run 3 separate 8 gauge wires. Breakers were 3 x 50 amp double pull. This unit delivering full power for hot water make up,l devours 120 amps. So far one month in I enjoy it. In coming water or ground water temperature in conjunction with how hot you want the water called (rise) dictates what size unit you go with. This will tell you gpm (gallons per minute) the unit will deliver. Beware of your electrical panel. The breaker space needed and service to handle the type and size unit you choose. Typically these should save you 15-20% on your electric bill. I like mine. I choose for space saving and money. One note you can use a small tank and tankless at the same time. The tank would heat water 20 to 30 degrees and the tankless would bring the temperature the rest of the way. I believe you would save money but space would be gone. I have 68 degrees coming in and heat to 118 to 120. If you call for more hot water than it can heat you still get hot but not as hot as you set it. Beats a tank unit when the water just turns cold.Hope this helps

Rated 4.0 out of 5.0 by chris I recommend this product over all other instant w/heaters
I have had the tempra 29 installed in my home for over 5 years now. All though i am not convinced that it is as efficient as they claim. i have over seen several alternative brands in homes that i have constructed from gas to electric installations and chose this particular brand and size for my own personal home and have been overall pleased with my decision. Your flows are limited when using these type heaters which means slower fill times. do the math. 30 minutes to fill a bath tub @ 14.4KW = 5,256Kw a year for each person in you home that baths daily. Thats more than a 50 gal tank heater uses each year. So my suggestion is to not install to save money but for convenience only. Further more by code you will need a 400amp service to install this beast in new construction.

Rated 5.0 out of 5.0 by Eslcsl1030 Excellent product! Works well for whole house!
Background: We originally had a 50 gallon propane hot water heater, coupled with a hydronic air handler for home heating. The combined usage made for very expensive propane bills, so we decided to upgrade to a tankless system. After reading reviews and doing some homework, we decided this was the best unit for us.
Homework: We live in the Pacific Northwest and our inlet temperature is around 40 degrees, so we were concerned that the resultant temperature rise would limit flow beyond usage but this system delivers! When deciding if this system is the right one for you, take into account that you will need room for 3 double throw 50 amp breakers(6 slots) and atleast a 200 amp electrical service to your home. Wiring requires 8/3 wire (w/o ground). If you are atleast somewhat competent with electrical work, you can install this yourself no problem. Took me about a day to do it all myself.
The system keeps and maintains 123 degrees comfortably for dishwasher, hydronic furnace, laundry, and shower at same time (although we have low flow energy efficient items).
The cons to this system is the expense of copper wire and items required to install. Even if you do it yourself your looking at a couple hundred dollars for just the hardware but in my opinion it will make it up in a few years from not having to heat the water all day and night while its not being used. The next con is that this system requires a larger pull on demand to activate the heating element. It's not an issue really but if you like to just turn hot water to a trickle, this will not work. The last possible con would be its a 28kw system so it's a huge electrical pull when used. Just make sure your home has enough room left over to use this system before you buy it. Just for a reference, I calculated that it will cost us $3.28 for every hour of run time of the water heater.
Over all it's a great unit, works as advertised, heat is constant and nice and even regardless of what's being turned on or off. The benefit of the "plus" system vice the other is that this system will automatically throttle pressure to ensure temperature maintains consistency. Good value . I recommend!

Rated 5.0 out of 5.0 by Vicar So far, so good, But...make sure you have adequate electrical service.
We recently had the Tempra 29 Plus installed as a replacement for our Noritz propane on-demand water heater. Plenty of hot water for our all electric home. Since we recently also had our propane powered furnace replaced with a heat pump we are wondering about whether, or not, we should upgrade to 400 amp from our current 200 amp service. We have not pushed things to the limit....running showers, dishwasher, dryer heat pump, frig and oven simultaneously. So far, so good. Time will tell.
