New product

The electronic E-comfort instant water heater DCX Next is designed for easy operation. One of the five typical hot water temperatures can be selected using the sensor button. Each temperature is indicated by an easily understandable colour display.

Electronically controlled instantaneous water heater with simple operating concept
One-button control panel for quick and easy temperature selection in five levels: 35 °C, 38 °C, 42 °C, 48 °C and 55 °C
Electronic safety system with air bubble detection, temperature and pressure shut-off
Temperature stable up to the power limit. TWIN TEMPERATURE Control TTC^® ensures precise temperature control to the degree, even with fluctuations in water pressure.
With Multiple Power System MPS^® the maximum power consumption is determined at installation: 18, 21, 24 or 27 kW, 400 V
Suitable for water-saving taps due to particularly low switch-on water quantity from 1.5 l/min thanks to innovative water flow technology
Dimensions (height × width × depth): 46.8 × 23.9 × 9.6 cm

1) The selected power rating determines the values of nominal current, cable diameter and hot water output

2) Temperature increase e.g. from 12 °C to 40 °C, mixed water

3) Limited flow amount for optimal temperature increase

4) Depending on the selected power rating
