The Baxi 7224342 Pressure Differential Assembly Kit is a replacement hydraulic component designed for selected Baxi, Main and Potterton combination boilers.
The assembly forms part of the boiler's hydraulic control system, helping manage the flow of water between the central heating and domestic hot water circuits. In combination boilers, the diverter valve directs heated water to either the radiators or the hot water outlet as required, allowing both heating and hot water to be provided without a separate storage cylinder.
Suitable for selected Baxi Combi, Main Combi HE and Potterton Performa HE models, this replacement kit is an important component for compatible boiler servicing and repairs.
Always check the existing part number and exact boiler model before ordering to ensure compatibility.
