CFX-U FUNKTRONIC MPS

The new instantaneous water heater CFX-U is a particularly clever 
and energy-efficient way to deliver hot water to the kitchen sink. 
The compact unit requires very little space when installed below the 
kitchen sink, whilst the user is able to set the temperature at his 
convenience using the ingenious remote control. The temperature at 
the point of use is set precisely; thus, avoiding heat loss caused by 
mixing hot and cold water.
