Product Information: This part is based around the diverter valve section. The diverter valve is a mechanism that only appears in combi boilers. It allows the hot water to be sent to the heating system (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 diverter valve allowing use of hot water and heating without the need for a cylinder
This part is present in 6 different boilers in the Baxi range including the Baxi PERFORMA 24 I HE , PERFORMA 28I , COMBI INSTANT HE , COMBI INSTANT , COMBI INSTANT HE .
