The new Tempra 15 Trend replaces the discontinued Tempra 15B.

It offers all the same features of the Tempra 15B, with a new digital display, in a modern white powder-coated case.

The Stiebel Eltron Tempra 15 Trend electric tankless water heater is our smallest whole house water heater. This 14.4 KW unit is generally recommended for moderate climates where the coldest incoming water temperature is 65° F or greater. As a whole house model, the Tempra 15 Trend is best suited to homes with modest flow rate needs in the southernmost regions of the U.S. (i.e. Southern California, Texas, Florida, etc.), as well as Mexico, and the Caribbean. The Tempra 15 Trend is also frequently used as a point-of-use water heater for low flow applications in colder climates.

Like all Tempra Series tankless water heaters, the Tempra 15 Trend features a digital temperature display and convenient dial selector which allows you to set the desired output water temperature at any level between 86 and 125F (30 and 52C). 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 15 Trend 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 100 AMP household electrical service is highly recommended and will likely be required to install this model. Most homes have at least 100 AMPS of service, however, 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.
