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