E-Tankless Electric Tankless Water Heaters

Stiebel Eltron Tempra 15 Tankless Water Heater

The Stiebel Eltron Tempra 15 electric tankless water heater is the smallest heater that we typically use for whole house applications. This 14.4 KW unit is generally recommended for warm climate regions including the southernmost regions of the U.S. (i.e. Southern California, Texas, Florida, etc.), as well as Mexico, and the Caribbean. It is best suited to regions where the coldest incoming water temperature is 65° F or greater. The Tempra 15 is also a popular point-of-use tankless water heater for low flow applications in cooler climates.

Like all Tempra Series tankless water heaters, the Tempra 15 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 15 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: A minimum 100 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.
