Pumps

The pump is fitted inside the boiler to circulate water around the boiler, it also circulates water around the central heating system. It ensures that the heat that is created by the boiler is transferred from the boiler to where it is required such as the radiators or through the plate heat exchanger out to the hot tap. In most combi boilers the pump is usually located before the diverter valve to allow circulation through the central heating and domestic hot water system.
