The Baxi 242497 is a genuine OEM complete heat exchanger assembly designed for selected Baxi Combi, Baxi Solo, and Main boilers. The heat exchanger is one of the most critical components in the heating system, responsible for transferring heat from the burner into the water circulating through the central heating and domestic hot water circuits.

A failing heat exchanger may cause poor heating performance, kettling noises, reduced flow temperatures, overheating lockouts, internal leaks, or contamination of system water. Replacing it with this complete genuine Baxi assembly restores optimal heat transfer efficiency and ensures safe, reliable boiler operation.
