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 guided to the heating system (radiators, etc.) or to the DHW system (taps, etc.). This feature is what seperates a normal boiler from a combi boiler due to the fact that a cylinder is not required and it can still provide both heating and hot water .
