This part is based around the diverter valve section. The diverter valve is directional water mechanism 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 what makes a combi boiler so popular due to the fact that a combi boiler wouldn’t require a cylinder to provide heating and hot water.
