Continued technological innovation from the World Leader

DHX Plus offers flexible installation options - and looks good.

Welcome to the latest water heating technology revolution from Stiebel Eltron.

The robust and trouble-free Direct Coil heating system of the DHX series, Stiebel Eltron’s most advanced technology, is self-cleaning for superior limescale resistance. Ideal for residential and commercial point-of-use applications, DHX models heat water endlessly on demand at 99% efficiency. They have no stand-by energy losses because they do not store hot water like tank water heaters.

Most advanced features

DHX Plus models include both the robust and trouble-free Direct Coil heating system and also Advanced Flow Control. Advanced Flow Control, patented in Germany, and exclusive to Stiebel Eltron tankless heaters, has been a feature of our whole-house Tempra® Plus models for years. If hot water demand exceeds working capacity, Advanced Flow Control automatically maintains consistent temperatures by slightly reducing flow.

Now available in the DHX 12-2 Plus and DHX 15-2 Plus, Advanced Flow Control allows these models to satisfy installation with a single water heater for multiple sinks. A Direct Coil DHX will provide the correct temperature water at multiple sinks at the same time, without delivering colder water if the system is overloaded by one too many taps being opened.

The best technology

In addition to the extra benefits detailed above, the new DHX Plus models continue the benefits that are a part of the entire Stiebel Eltron electric tankless line. Ideal for both residential and commercial point-of-use applications, the new DHX Plus models heat water endlessly on demand at 99% efficiency.  Activation rate for DHX models is a low 0.264 GPM.

No venting is required and the compact European design can be installed with the unit visible. The desired output temperature is easily set using the dial and display on the cover.

Digital backlit display

DHX Plus models are equipped with our largest digital display screen. Desired output temperature is easily set using the dial and display on the cover. These models also have additional features such as a cost savings calculator, real-time capacity monitoring, preset temperature buttons, and for safety, a user-selectable scald guard setting, and front-panel control lock-out setting.

Size it right for endless hot water

Sizing Guide Map

The DHX Trend excels at supplying water at a constant temperature, but the amount of hot water and its temperature depends on the incoming cold-water temperature and the size of the DHX model. The correct model size must be chosen by using the DHX Sizing Guide or by calling Stiebel Eltron’s friendly support team at 800.582.8423.

Stiebel Eltron invented electric tankless water heating almost 100 years ago, and is still the industry pioneer and world leader, with an engineering and manufacturing tradition of excellence.
