DESCRIPTION
The high efficiency Grundfos Comfort PM range is a product for domestic hot water re-circulation with lead free drinking water suitable pump housing for single and two-family houses powered by a high efficiency 1-phase, 12-pole, permanent magnet motor. The AUTOADAPT function has been developed for domestic hot-water systems with hot water tanks as primary heating source. In domestic hot water systems with integrated temperature control functionality for raising and lowering the temperature on the recirculation pipe, Grundfos recommends using the COMFORT BX or COMFORT B models. To get the full advantages of the COMFORT AUTO model with the AUTOADAPT feature, Grundfos recommends installing the pump in systems with hot water storage tanks.
