Pressure Balancing Electric Tankless Water Heater for 2 Bath Home


  • Unlimited Supply of Hot Water: Keeps heating water instantly as you require. The Tempra(tm) system completely replaces a conventional tank heater with no disruption to your comfort and hot water needs.
  • Saves Energy and Reduces Your Electric Bill: Electric tank type water heaters are subject to stand-by losses which amount to 15 - 20% of the kWH used. Changing to a tankless system results in savings of 15 - 20%.
  • Control Temperature Simply by Setting a Dial: Set the knob on the front cover and enjoy water temperatures between 86 degreeF (30 degreeC) and 125 degreeF (52 degreeC). Change the desired temperature at anytime. Advanced microprocessor technology ensures that the water temperature never deviates from the set point.
  • Sleek Design Saves Space: The Tempra(tm) takes up considerably less space than conventional tank type water tanks and saves valuable living space.
  • Proven Reliability: Stiebel Eltron has an enviable track record of engineering excellence and product quality. The three years parts warranty is unique in the industry. You can depend on the Tempra(tm) for many years to come.
  • Tempra 24 vs. Tempra 24 Plus: The Tempra 24 Plus (this model) expands on the Tempra 24 by adding a pressure balancing feature to the unit. Should a unit be hooked up to more than one application, for example, a shower and a kitchen faucet, the demand for hot water may occasionally exceed the capabilities of the tankless water heater. Should this occur when using the Tempra 24, the water temperature will go down. Should this occur when using the Tempra 24 Plus, the unit will properly lower the cold water pressure to compensate for the demand, resulting in a total drop in water pressure at the shower and kitchen sink faucet, but temperature remains constant.

Stiebel Eltron TEMPRA 24 PLUS Reviews

Rated 5 out of 5 by from Work Great I had the 24 Plus installed in my DC Condo in December '09 and I couldn't be happier. The installation required coordination between the plumber and electricians as an upgrade was needed to the electrical panel. Since every inch of space counts in my home, it was installed under-counter next to the sink. The plumbers and electricians were at the apartment at the same time and this helped. So far the the water heater is performing very well, heating water quickly and there is no lack of hot water whatsoever. Overall I'm very pleased with the purchase. Lastly I had to order the unit on short notice and paid for overnight shipping. It was delivered to my home within 24 hours. Overall a great experience with

Rated 5 out of 5 by from Easy installation, works great! I am very happy with our new water heater. I could not believe how small it is, it takes up no floor space and very little wall space. It was quite easy to install. I did have to install two new electrical circuits, but I knew that after researching the Stiebel site. I am glad we bought the largest unit that we could install with our electrical panel. We have plenty of hot water and we never run out. We have had our unit for several months now and we highly recommend it!

Rated 5 out of 5 by from best thing since sliced bread this item has saved me more than i would have dreamed! My electric dropped over $80 the first month. And just like promised endless supply of hot water. One of the best features of the unit is the ability to set the water temperture with such ease. I'm heating water to my entire home with no temperture drop. It does take about 30 to 40 seconds for the water to get to the faucet. In my eyes that's a small price to pay for such a nice savings on my electric bill! Will be buying one for my parents home very soon.
