Grundfos Comfort System

Applications: Hot Water Recirculation – ensures that there is always hot water available when it is needed and prevents water wastage resulting from the draining of cold water. The system uses the cold water supply line as the “return-line” to the water heater. A Comfort pump is used to create a pressure differential that allows the cold water in the hot water supply line to bypass (at low volume) into the cold supply line through a patented thermostatically controlled valve that is mounted under the sink furthest from the water heater.
