Product Information: This part is based around the diverter valve section. The diverter valve is directional water device that only appears in combi boilers. It allows the hot water to be directed to the central heating (radiators, etc.) or to the domestic hot water system (taps, etc.). This feature is what seperates a normal boiler from a combi boiler due to the fact the boiler can provide hot water and heating without the need for a cylinder.
This part is present in 10 different boilers in the Biasi range including the Biasi 20SE , PRISMA 28SE , 24S 24S , 28S , PRISMA 24SER .
