Introducing Priority Hot Water Pack with OpenTherm®


Cost-effective and lower your carbon footprint

This pack ensures higher efficiency with lower demand on the boiler.

Allows flow and return temperatures to be reduced thereby increasing the efficiency of the heating circuit.

Lower flow and return temperatures ensure the boiler operates within its condensing range.

Connecting the OFF contact of the hot water receiver to the COM contact of the heating receiver will give priority hot water. Once the hot water is called for, the heating will not operate.
