The Stiebel Eltron Tempra 29 electric tankless water heater is one of the most powerful electric tankless water heaters available in North America. This 28.8KW tankless heater is designed for whole house and commercial applications in cold climates where the incoming water temperature can drop below 40° F. It is also a popular choice for homes in warmer climates with high flow demands where multiple simultaneous hot water demands are required (up to 6 gallons per minute).

Like all Tempra Series tankless water heaters, the Tempra 29 features a convenient dial selector which allows you to set the desired output water temperature at any level between 86 and 140F. Most importantly, 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. In layman's terms, the Tempra 29 will automatically sense the water flow rate and temperature, calculate how much power is needed to do the job, and will apply exactly that much power so it can precisely maintain the desired output temperature regardless of whether the flow rate changes or not. The result is the most precise temperature control of any tankless water heater on the market today!

Please note: A minimum 200 AMP household electrical service is highly recommended and will likely be required to install this model. If you are unsure of your electrical capacity in your home, please consult your electrician or contact us for assistance before ordering.

* 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.
