Get the superior, reliable, and energy-saving tankless electric water heater for your home.
Stiebel Eltron has been a leader and pioneer in the tankless water heating industry for almost 90 years. Impressive energy-saving performance, advanced technology, and a compact design are just some of the reasons why you should consider a Tempra hot water system.
Features
3-Phase 208 V Power Ready
All Stiebel Eltron Tempra units are designed for single phase power but can be wired for 208 Volt 3-phase power.
Unlimited Hot Water Supply
Keeps heating water instantly as you need. Tempra heaters can completely replace a conventional tank heater without disrupting your comfort or hot water supply.
Reduces Your Electric Bill by Saving Energy
Electric tank type water heaters consume stand-by electricity which equals approx. 15% to 20% of the total kWH used. Switching to a tankless water heater will save you this 15% to 20%.
Simple Dial Temperature Control
Set the knob on the front and enjoy hot water at a constant temperature. An advanced microprocessor ensures that the water temperature will never deviate from the set point.
Sleek Space-Saving Design
The Tempra takes up considerably less space than traditional tank type water heaters and saves valuable living space.
Proven to be Reliable
With its 7-year leakage and 3-year parts warranty, you can depend on the Tempra for years to come. Stiebel Eltron has an glowing track record of product quality and engineering excellence.
Difference between Tempra and Tempra Plus heaters
Tempra Plus includes Tempra Advanced Flow Control. This ground-breaking feature automatically, slightly reduces the water flow rate to maintain the level of hot water temperature that you have set on the dial on the front of the heater. In contrast, with the standard Tempra heater, and typically all modulated tankless heaters, if the demand for hot water exceeds the heater's capacity, then the water temperature coming out your shower or faucet will drop.
