Stiebel Eltron Tempra Series Tankless Water Heater
Models and Specifications
The Stiebel Eltron Tempra Series electric tankless water heater is the most sophisticated thermostatically-controlled on demand, instantaneous water heater available on the market today. Stiebel Eltron offers 6 models ranging from 12 to 36 KW in power, to meet a wide range of point-of-use, whole house, as well as commercial applications. Each model features Stiebel Eltron's advanced microprocessor technology which constantly monitors the water flow rate and incoming water temperature and adjusts the power level to maintain a precise output temperature as selected by the user. A simple digital display and adjustment dial on the front of the heater allows you to set the output water temperature to whatever temperature you desire between 86 and 125F (30 to 52C). To learn more about what makes Stiebel Eltron tankless heaters superior to its competition, visit our comparison of tankless water heater technologies page.
Selecting a model for your application is largely dependent on your incoming water temperature and flow rate requirements. Please view our Tankless Water Heater Model Selector Page for proper sizing information.

| Max. Output Temperature |
The maximum output temperature is a function of incoming water temperature and water flow rate. For residential applications, all units are factory pre-set to permit a temperature setting from 86F to 125F (30 to 52C). The temperature setting can be easily adjusted using the adjustemnt dial and digital temp display on the front of the heater. |

* 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.
