Product Description

Stiebel Eltron Tempra 24 Electric Tankless Water HeaterUnlimited supply of hot water: The Tempra; continually heats water instantaneously as you require it - and only when you require it. The Tempra; unit completely replaces a conventional tank heater with no disruption to your comfort and hot water needs.Save energy and reduce your electric bill: Electric tank type water heaters are subject to stand-by losses which amount to 15 - 20% of the kWH used. In addition, water in a tank has to be heated hotter than necessary to account for these stand-by losses. Changing to a tankless system like the Tempra; eliminates these problems and results in typical savings of at least 15 - 20% on the heating portion of your electric bill.Sleek design saves space: The Tempra; takes up considerably less space than conventional tank type water heaters and saves valuable living space.Control temperature simply by setting a dial: Set the knob on the front cover and enjoy water temperatures between 86;F (30;C) and 125;F (52;C). Change the desired temperature at anytime. Advanced microprocessor technology ensures that the water temperature never deviates from the set point.Better than gas: The Tempra; has several advantages over a gas-type tankless water heater. Compared to many similar gas tankless models the Tempra; is less expensive to purchase. Installation is also much simpler and cheaper since it is not necessary to vent a Tempra; to the outside. The venting that a gas unit requires causes anywhere from a 10 - 20% efficiency reduction from heat escaping out the exhaust pipe. Furthermore, for every cubic foot of gas burned, two cubic feet of air have to be mixed in to create ideal combustion. In a cold climate, this hurts efficiency further. When a gas unit fires, it draws in air around it, heats the water, and then expels warm exhaust outside. Since no house is airtight, this suction action causes a drafting condition where cold air from the outside seeps back in through d

NOT a whole house water heater!!!
Firstly let me say that this water heater is not appropriate for whole house use. It works fairly well with a faucet application but I was never able to get the water hot enough for a bath or shower at a normal gpm rate of 2-4 gallons. And I had three-yes that's right 3 of them. They all failed. I purchased this hot water heater online last August after much research and saw no negative reviews. The price was better than the comparable Bosch that my inlaws had installed and have been using with no problems. Each and every time a unit failed I dealt directly with Stiebel Eltron customer service reps at the home office in Massachusetts and they coached my installer and myself through multiple troubleshooting/pulling apart exercises to try to solve the problems over the phone. They had to send out a new unit twice during which time I had no hot water during the transit times, not to mention already having not had any hot water due to failure. If you do decide to order one of these units and use it as your whole house water heater consider getting a membership to a gym or befriending neighbors so that you will be able to take showers when it fails you, too.

bad machine(s)
After much consideration, and after exchanging 2 new units via Stiebel-Eltron customer service, I conclude that there is a basic design flaw in this water heater. The water heater does not perform according to the Stiebel-Eltron specifications. In the first 2 units I had, the delivered water temperature at a single faucet was always 8-10 degrees below the temperature set at the unit. In the 3rd unit, the temperature is maintained, but only for 6-7 minutes, after which it drops consistently and considerably. It is not a problem with my particular installation, believe me I spent many hours trying to eliminate any possibility that what I had done with the plumbing and electrical service to the unit was at fault. And what is true for this model is probably true for all of the other models as well.
Given my experiences, I can't imagine anyone giving this product a good rating. The only other review I have read of this model reports very similar things to what I've experienced.
I spent $600 on the unit, another $500 on installation, and ALOT of time trouble-shooting, all to get an unreliable product. I'd never buy anything from them again!

Works Great.
I got tired of replacing water tanks and decided to go tankless. I spent a lot of time researching this item and installed it myself. It worked great from the very first turn-on. I thought the unit was well engineered from the moment I received it.
I'm able to run 2 showers with shower heads that put out 2.5 GPM each. If you want to compare inlet water temps, I live in North Texas.
I never measured the exact temperature of the water but I know the temperature adjustment works just fine because I've adjusted it a couple of times. Specifically to increase the temp for the Kitchen sink.
