Product innovation
You want to enjoy the best comfort in the shower and bathroom, but install the instantaneous water heater hidden? The E-comfort instant water heater DFX Next is the optimal choice for this. Technically equipped to a high standard like our top-of-the-line DSX Touch, but with the new FX Next Bluetooth remote control instead of the touch display. This means that the device meets the highest comfort requirements even when installed in a hidden location.
Modern technology, durable materials and the compact design ensure high quality and are resource-saving. The unit is operated intuitively via the new FX Next remote control.
The integrated Bluetooth and WLAN function also allows the unit to be operated by smartphone, tablet or voice control. Using the "Smart Control" app makes it easier to commission and maintain the unit. The individual consumption values of several users can also be displayed quickly and easily. That is contemporary operating convenience!
By the way, the DFX Next can act as a home server for CLAGE next generation instantaneous water heaters. Built-in future.
