Rated 3.9 out of 5 by 15 reviewers.
Rated 4.0 out of 5.0 by Met all of my expectations I had done extensive research before purchasing this product, and i am pleased with the results. i purchased this hot water heater 3 months ago, replacing my old tank water heater. I live in New England and this heater gets the water very hot reasonably fast. A couple of things future buyers should know before purchasing this item: It does require a 100 AMP service to run, and i paid $150.00 for the cables to run from my breaker box to the heater. You will also most likely have to pay a electrician to do the wiring, but it only takes about 40 minutes to get it hooked up. The plumbing is self explanatory and easy for someone with general knowledge of the trade. I only have 1 bathroom and my kitchen sink that need hot water (i wash my clothes with cold water) and this water heater easily does the trick, the one issue i had was that the volume of water going into my bathtub with the valve fully open was to much to heat, so if i want to get the tub full of warm water i can only open the shower valve half way. For the price of the product with the 10 year warranty it is a great deal. I saved $35 off my first months electric bill. April 23, 2012
Rated 5.0 out of 5.0 by perfect, as advertised I bought this tankless hot water heater because it was time to stop heating fifty gallons of water 24/7 when I really only need it twice a day. I did my homework and decided the Tempra 24 was most suited to my home (one adult, two teenage daughters, two bathrooms). Installation was quite simple; I did my own plumbing and electrical installation following the instructions. Within twenty minutes of finishing the wiring, I had bled the lines and my 15 year old daughter was in the shower—what better test? She emerged twenty minutes later declaring it an unqualified success, and she didn't even know I had washed the dishes while she was in the shower. It's been a month now, and the heater has met every challenge. Twenty years ago I installed a tankless hot water heater in a new home I built, and it was satisfactory, but had issues. There is simply no comparison—in both manufacturing and performance, this is light years ahead. I set the temperature at 116 degrees and it maintains it perfectly all the time. My main concern was warm water at the sink—since the sink is served by smaller lines, would I draw enough flow to activate the heater? Turns out I did, no worries at all. I've already urged everyone I know to go tankless when it's time to replace their heater—or sooner. And I will be pleased to recommend Stiebel. December 25, 2012
Rated 5.0 out of 5.0 by So far so good Had this professionally installed with some new construction about 3 weeks ago and it is working flawlessly. We did upgrade to a 200 amp service for this to work. It does draw some power. When we turn on the hot water, we do get a very minor flick of the lighting. It supplies very hot water that does not run out. It is very easy to change the settings.It has been too early to tell about any energy savings on the electric bill. It does take a few seconds for the water to come out hot for some outlets located about 20-25 feet away.Overall very pleased. The only negative is we may take longer showers raising the water bill! May 3, 2014
Rated 2.0 out of 5.0 by NOT FOR FLORIDA WATER It was not what we hoped for. No significant savings on electric but it is compact. For my wife and I the was temperature was OK. 2 showers work at the same time. After 5 years in service one element breaker popped and kept popping. Called Steibel and they said it was my bad water that clogged the element. (City of Daytona Beach water, No problem with the old tank heater that was still going after 20 years) Paid $195 for a new element and replaced it myself. 3 months later the second element went out and paid $195.00 again. I hope the elements last another 3-4 years so I can replace it with a gas on demand heater. More people need to respond to this company so that they can design something works for 10+ years without failures. April 13, 2015
Rated 5.0 out of 5.0 by Very happy with this product The tankless water heater works as advertised. I replaced a very large tank type to save space. No lack of hot water, actually very hot! Watch your temp setting. We have a lag of 10-15 seconds in the morning shower before hot water arrives, not much more than the tank type. No cold water pulse during delivery as some have claimed. This heater uses a lot of energy when operating, but our first months bill was lower than other comparable months. I am very pleased with the unit so far, installed myself with no issues, and I hate plumbing! Thanks, Home Depot for carrying this premium product as well as all needed connections. Now, if I just hadn't purchased it the same week as the security breach....... September 25, 2014
Rated 4.0 out of 5.0 by Great unit but you can only use one source at a time. Installed unit yesterday. Very easy to install (I am an electrician). However if you use more than one source at a time the water temp gets way too low (70 drgrees). My input temp is 49 degrees right now (FEB) I need the space in my kitchen for a remodel and will miss my old water tank. The good thing is I can shower forever without running out of water. The unit comes with 3/4" fittings but the tubing inside is only 3/8" so dont be fooled into thinking you will get great water flow. All in all it is a good unit and I will install a point of use under the kitchen sink to supply the sink and dishwasher from the cold feed. February 10, 2013
Rated 3.0 out of 5.0 by Tankless water heater Had to return the product due to an amperage insufficient power box. Could not afford to upgrade the box. December 30, 2014
Rated 1.0 out of 5.0 by unknown I bought the product by the sizing chart, and the charts are based on strict water conservation methods. These water conservation methods are not used by my state, which means the product that i bought for a 2 bathroom home will not heat the water. Plus the power consumption is high. In short, High power bill, cold water. October 9, 2014
