    Product details

    Use water your way

    Every one of our fully electronic instantaneous water heater models provides hot water at the exact temperature you have set at all times. No ifs or buts. The 4i technology ensures that nothing interferes with the outlet temperature. Enjoy constant hot water in the shower, even if somebody needs to wash their hands at the washbasin beside you.

     

    Make all your own choices

    The haptic rotary selector ensures the appliance is very easy to operate: intuitive, instant, precise.

     

    Know exactly what's going on

    The illuminated multifunction display gives you a clear overview of your required water temperature, the ECO level and current power consumption. You can check energy consumption, flow rate, time, status and service information in the lower part of the display.


    High tech for guaranteed accurate temperature delivery

    The DHE comfort instantaneous water heater from STIEBEL ELTRON guarantees high energy efficiency. Full electronic output control with 4i technology enables not only energy and water savings of up to 30%, but also accurate temperature delivery – at all times. The temperature is continuously adjustable from 20 to 60 °C. Using preheated water from a DHW heat pump or solar thermal system, for example, further improves the energy balance.

    The large, backlit multifunction display and extremely handy new operating dial ensure excellent operating convenience. In addition to energy and water consumption displays, a wide range of other functions are available, such as temperature limit, automated bath filling and operating lock features. The two memory buttons can be assigned individual temperatures. Thanks to the rotatable appliance cover and programming unit, even appliances installed undersink can be operated with ease.
