GRUNDFOS COMFORT

The COMFORT range of energy-saving pumps helps reduce energy consumption and water waste. COMFORT wet-running pumps are installed on the return line of the hot water circulation system and operate noiselessly. They ensure that hot water is available at the tap or shower at any time without waiting. This eliminates waiting time for hot water and the waste of cold water that has to be drained from the tap.
