Worcester Greenstar 10-Plate Heat Exchanger – Refurbished | Part No. 87161066860

The plate heat exchanger is one of the most critical components in a combi boiler — it's where the central heating circuit transfers heat to the domestic hot water supply. When it becomes fouled, corroded or develops a crack, hot water performance drops sharply and system efficiency suffers. The Worcester Greenstar 10-Plate Heat Exchanger (Part No. 87161066860) is the correct OEM-specification replacement for the Greenstar 25i Combi ERP, 24i Junior HE, and compatible system models — restoring full heat transfer performance and hot water delivery.

This is a professionally refurbished genuine Worcester component. Each unit is cleaned, pressure-tested and inspected to OEM standards before dispatch, giving you manufacturer-grade performance at a significantly lower cost. The 10-plate construction fits directly as a like-for-like replacement, requiring no modifications and enabling a straightforward, compliant installation.
