Glowworm Lpg Boiler Diverter Valve

The diverter valve is directional water mechanism that only appears in combi boilers. It allows the hot water to be sent to the central heating system (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 the boiler can provide hot water and heating without the need for a cylinder.
