Stiebel Eltron Tempra 36 Tankless Water Heater

One of the most powerful electric tankless water heaters available today, the 36 KW Stiebel Eltron Tempra 36 tankless water heater was designed primarily for high flow rate applications in cold climates where the incoming water temperature can drop below 40° F. It is also a popular choice for homes and commercial applications in warmer climates where very high flow demands (up to 8 gallons per minute depending on the incoming water temperature) are necessary due to multiple large simultaneous hot water demands.

Like all Tempra Series tankless water heaters, the Tempra 36 features true microprocessor-controlled temperature regulation and a convenient digital temperature display and dial selector which allows you to set the desired output water temperature at any level between 86 and 125F (30 and 52C). It is one of the only tankless water heaters on the market that features a true thermostatic temperature control and full power-modulation based on both the incoming water temperature and the water flow rate. The Tempra 36 will automatically adjust its power output to accommodate changes in the incoming water temperature and flow rate so it can precisely maintain the desired output temperature. The result is the most precise temperature control of any tankless water heater on the market today!

* Breaker size and wire gauge must meet all applicable local, state, provincial, and national electrical codes for your area - these are only guidelines that will apply to most installations. Some codes require use of electrical sub-panel for installation, especially when heater is not mounted within line-of-sight of the main electrical panel. Wiring should be sized to maintain a voltage drop of less than 3% under load. Please consult your electrician for more details.

Please note: the electrical requirements of this unit prohibit its installation in many homes. A minimum 300 AMP household electrical service is highly recommended. Only a small percentage of homes are equipped with a 300 AMP service. Please consult your electrician before ordering if you are unsure of your electrical capacity in your home, or consider another model selection.
