GRUNDFOS COMFORT

Always have hot water available throughout the house without waiting with the COMFORT range of pumps for hot water circulation systems in single and multi-family homes. The COMFORT range of energy-efficient 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.

Choose the best circulation pump for you

Each COMFORT Series pump is designed to provide maximum convenience while minimizing energy consumption. Making the right choice is simple, just determine which control mode suits your household requirements. Compared to continuous operation, different control modes can further reduce heat energy loss due to circulation.
