The diverter valve is a device that only appears in combi boilers. It allows the hot water to be sent to the heating system (radiators, etc.) or to the domestic hot water system (taps, etc.). This feature is what makes a combi boiler so popular due to the fact the boiler can provide hot water and heating without the need for a cylinder.
