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 to buy 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 amounts to 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 coming out of the heater 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

Stiebel Eltron has an glowing track record of product quality and engineering excellence. Its 3-year parts warranty is among the best in the water heating industry. You can depend on the Tempra for years to come.

Difference between Tempra and Tempra Plus heaters

Tempra Plus has an additional feature: Tempra Advanced Flow Control. All tankless water heaters may not reach the output temperature you seek if the hot water flow volume is too high. But, the Tempra Plus heater will automatically reduce the water flow rate, to maintain that hot water temperature you have set. In contrast, with the standard Tempra heater, and every other modulated tankless heater, if the demand for hot water exceeds the heater's capacity, then the water temperature coming out your shower or faucet will drop.
