Grundfos COMFORT with continuous operation:
Recirculating hot water in a smart way

COMFORT circulators are efficient for hot water recirculation in residential buildings with a dedicated return line.

The circulators are compatible with all types of water heater tanks, tankless systems, and solar or heat pump systems, regardless of whether the system has mixing valves or thermostatic valves installed.

COMFORT features a 24/7 continuous operation program, which is suitable for external control by a connected timer, gas boiler, or heat pump controller. These circulators feature a compact design that houses a high-efficiency permanent magnet motor with an integrated control unit.

The spherical rotor, equipped with an impeller, ensures optimal functionality and is supported by a robust single ball bearing system.
The pump housing is made of brass approved for drinking water and guarantees both safety and reliability.
