Product Information: The diverter valve is a mechanism that only appears in combi boilers. It allows the hot water to be guided to the heating system (radiators, etc.) or to the DHW 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 13 different boilers in the Vaillant range including the Vaillant VCW 280 XT , VCW 242 E , VCW 240 T , VCW 221 T , VCW 282 E .
