Three Year Limited Warranty

For Use In Homes, Apartments, Condos,
Various Commercial and Industrial Facilities.

Unlimited Supply Of Hot Water.
Keeps heating water instantly as you require. The Tempra™ 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%.

Sleek Design Saves Space.
Tempra™ takes up considerably less space than conventional tank type water tanks 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.

Proven Reliability Backed by a Three Year Warranty.
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™ for many years to come.

Seismic Proof Construction
The Tempra™ is a tankless water heater system, and is thereby not subject to seismic code. There is no need for preventative construction, as required when using a tank type water heater.

We have done our homework. As an international leader in the tankless electric water heating industry, STIEBEL ELTRON is proud to have pioneered this technology.

The company’s German engineering and manufacturing tradition of excellence means that you can depend on its performance for many years to come.

The Tempra™ has several temperature and flow sensors which feed their readings into the unit’s proprietary microprocessor control. Heating elements are engaged in stages, achieving the temperature you desire. The Tempra™ continually monitors the water temperature it produces.
