This part is based around the diverter valve section. The diverter valve is directional water device that only appears in combi boilers. It allows the hot water to be redirected to the central heating (radiators, etc.) or to the domestic hot water system (taps, etc.). This feature is one of the reasons combi boilers are so popular in the market due to the fact the boiler can provide hot water and heating without the need for a cylinder .
