Efficiency and convenience in one sweep.

An especially smart solution for energy-efficient hot water supply at the kitchen sink is the E-compact instant water heater CFX-U. While the compact and space-saving unit is installed under the kitchen sink, the temperature of the instant water heater can be conveniently controlled via remote control. You can preselect the perfect temperature and avoid heat losses due to mixed water.

Awards E-compact instant water heater CFX-U
  • Electronically controlled instant water heater in compact design and wireless remote control for installation under the sink
  • Temperature setting from 20 °C to 60 °C via bidirectional wireless remote control
  • In the comfort zone between 35 °C and 43 °C, the temperature can be set in 0.5 degree increments
  • Adding cold water is no longer necessary
  • Easy installation under the kitchen sink facilitated by small dimensions and external ⅜" water connectors for unvented or vented installation
  • Precise temperatures due to TWIN TEMPERATURE control TTC® up to the capacity of the appliance
  • With the Multiple Power System MPS®, the maximum power rating is set at the time of installation
  • With power cable for permanent electrical connection
  • Dimensions (height × width × depth): 29.4 × 17.7 × 10.8 cm
