Ideal Isar boiler diverter valve is a component that opens and closes to provide hot water to go to either the radiators or the domestic hot water system taps and showers. The boiler diverter valve will always give priority to your hot water, so if you turn your central heating on and have a hot tap, it will heat up the water to the tap first. The diverter valves are a significant working component of the boiler, and so an issue could affect the heating system and hot water all around your house
