Stiebel Eltron Tempra Electric Tankless Water Heater

The Stiebel Eltron Tempra 12B electric tankless water heater is a popular, economically-priced point-of use tankless water heater used for low-flow applications such as single sinks in restrooms, powder rooms, kitchens, low-flow pool house showers, emergency eyewash stations, etc. This model is not generally considered sufficient for whole house applications, even in warm climate areas. Keeps heating water instantly as you require.

Like all Tempra Series tankless water heaters, the Tempra 12B features a convenient dial selector which allows you to set the desired output water temperature at any level between 86 and 131°F. 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. Simply put, the Tempra 12B 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.
