The Baxi 7224342 Pressure Differential Assembly Kit is a genuine replacement component set designed to monitor and regulate the pressure differential in compatible Baxi boiler systems. This assembly helps the boiler’s control system detect correct flow conditions by sensing differences between supply and return pressures, ensuring safe and efficient operation of the combustion and circulation processes. Manufactured to Baxi’s exact quality standards, the pressure differential assembly kit should be fitted by a qualified heating engineer during servicing, maintenance, or when replacing a worn, blocked, or faulty pressure sensing assembly.

Compatibility for the 7224342 pressure differential assembly kit includes Baxi Alpha, Combi, and Main Combi boiler models that utilise this specific pressure differential sensing configuration. Always verify your boiler’s exact model and part requirements before installation to ensure correct match and reliable performance.

Using a genuine Baxi pressure differential assembly kit helps maintain accurate flow detection, supports proper pump and burner sequencing, and contributes to the long-term safety, reliability, and efficient operation of your central heating and hot water system.
