Precise hot water convenience.

The CEX-U’s electronic controls ensure an energy-efficient hot water supply. The water is heated directly to the preset temperature while flowing though the unit. The temperature is selected by pushing one of the buttons on the LED panel, with factory settings programmed at 35 °C and 48 °C.

Awards E-compact instantaneous water heater CEX-U
  • Electronically controlled instant water heater in compact design for installation under the sink
  • Push-button operation panel with LED display for precise temperature setting between 20 °C and 60 °C
  • In the comfort zone between 35 °C and 43 °C, the temperature can be set in 0.5 degree increments
  • Two programming buttons for individual pre-set ­temperatures, optional temperature limitation as well as function indicators
  • Adding cold water is no longer necessary
  • Easy installation under the kitchen sink facilitated by small dimensions and external ⅜" water connectors for closed-outlet or open-outlet installation
  • Connection set (T-piece and flexible pressure hose) for an angle valve is included in delivery
  • With power cable for permanent electrical connection
  • Precise temperatures due to TWIN TEMPERATURE control TTC® up to the capacity of the appliance
  • Bare wire heating system IES® ensures longer life, less limescale and is efficient and easy to maintain
  • With the Multiple Power System MPS®, the maximum power rating is set at the time of installation
  • Can also be controlled by tablet or smartphone (from iOS 9 / Android-OS 4.4) (this requires an FXE3 (C) radio adapter and the "Smart Control" app)
  • Solar system compatible (supply temperature ≤ 60 °C)
  • Dimensions (height × width × depth): 29.4 × 17.7 × 10.4 cm
