Electronic instantaneous water heater


With its electronic control the CEX-U ELECTRONIC MPS® guarantees an energy-efficient supply of hot water. The water is heated to the pre-set temperature as it flows through the unit. Users are able to select the temperature at the touch of a button via the LCD control panel. The panel is equipped with two fixed-value keys, which are factory set to 35°C and 48°C.
  • Electronically controlled, under-sink instantaneous water heater in a compact design 
  • Precise temperatures due to TWIN TEMPERATURE control TTC® up to the capacity of the appliance 
  • Electronic safety system with air bubble detection
  • Easy installation under the kitchen sink due to small dimensions and outside “ water connections for installation directly to the tap connecting hose
  • Supplied with power cable for 3-phase power supply for easy installation without opening the appliance
  • Multiple Power System MPS®: Power settings set during installation, 
    11 or 13.5 kW 400 V (approx. 5 l / min 20°C to 60°C)
  • Dimensions (H × W × D): 29.4 × 18 × 11 cm
  • Energy efficiency class A (Scale: A+ to F)

3-phase power supply with load shedding box 

If a 3-phase power supply is available in the house, it is not generally difficult for an electrician to provide the required 400 V power supply connection at the place of installation. However, if it is not possible to provide a discrete electrical connection a possible alternative is to install the instantaneous water heater together with the load shedding box LAB to the existing 3-phase cooker connection in the kitchen. This arrangement sees the electric cooker and the instantaneous water heater share the same connection, whereby the instantaneous water heater has priority. 
In everyday use briefly interrupting the power supply to the cooker has no negative effect on the cooking (possible only in conjunction with electro-mechanical cookers without electronic timing control).
