Comfort PM

Grundfos COMFORT UP PM circulation pumps ensure that hot water is available in the household immediately after turning on the tap, without wastefully draining cold water down the drain.

Models with the PM designation feature a built-in time program (timer), so the pump only runs when circulation is actually needed, saving electricity.
