This genuine Worcester Bosch flow unit is used in the diverter valve of Greenstar, Greenstar 8000 Life, Greenstar 8000 Style and Greenstar ErP boilers. A directional water device in combi boilers, a diverter valve directs hot water into a heating system or a hot water system. This feature means that combis are able to provide both heating and hot water without the need for a storage cylinder.
Worcester Bosch Flow Switch (also sometimes called a flow sensor or supply manifold) is a device commonly fitted internally to Worcester Bosch boilers. The flow switch senses when a hot water tap outlet has been opened (turned on) and there is demand for hot water. The water moves through the flow switch and then switches the boiler ignition sequence so that the domestic hot water is provided at the tap. All our Worcester Bosch Flow Switches are new and genuine manufacturer spares.
