Product Information: The diverter valve is a device that only appears in combi boilers. It allows the hot water to be sent to the central heating (radiators, etc.) or to the hot water system (taps, etc.). This feature is what seperates a normal boiler from a combi boiler due to the boiler being able to provide heating and hot water without requiring a cylinder.
This part is present in 6 different boilers in the Potterton range including the Potterton COMBI 100 , COMBI 80 , PUMA 100 , PUMA 100E , PUMA 80 .
