The Worcester Bosch 3-way valve diverter valve is a part that only appears in combi boilers. It allows the hot water to be sent to the central heating system (radiators, etc.) or to the hot water system (taps, etc.). Because a combination boiler would not need a cylinder to supply heating and hot water, this characteristic is what sets it apart from a standard boiler.
Suitable for the Worcester Greenstar HE FSN and HE Plus FSN boilers
