Worcester Bosch 24CDi Plate Heat Exchanger – Refurbished | Part No. 87161429000

Fluctuating water temperature, weak hot water flow, and reduced heating efficiency in a Worcester Bosch 24CDi or 26CDi Xtra boiler usually point to a worn or scaled plate heat exchanger. As the plates degrade, heat transfer between the primary heating circuit and the domestic hot water supply becomes unreliable. The Worcester Bosch 24CDi Plate Heat Exchanger (Part No. 87161429000) is the direct replacement that restores consistent heat transfer and reliable hot water.

This is a professionally refurbished unit — cleaned, descaled, and pressure-tested before dispatch — giving you dependable, manufacturer-grade performance at a meaningful saving over a new part. It's a direct fit across the compatible 24CDi and 26 CDI Xtra range.
