The diverter valve is a directional water device that only appears in combi boilers. It allows the hot water to be directed to the heating system (radiators, etc.) or to the DHW system (taps, etc.). This feature is what separates a normal boiler from a combi boiler due to the fact that a combi boiler wouldn’t require a cylinder to provide heating and hot water.
  • Cartridge for a Diverter Valve
  • Can provide both heating and hot water without requiring a storage cylinder
