Worcester Greenstar 12 Plate Heat Exchanger – Refurbished | Part No. 87161066860

A worn plate heat exchanger is a frequent cause of reduced heating efficiency and inconsistent hot water in Worcester Greenstar system and combi boilers. As the plates scale up, heat transfer between the primary and secondary circuits weakens, leading to fluctuating temperatures and a less responsive system overall. The Worcester Greenstar 12 Plate Heat Exchanger, Part No. 87161066860, is the genuine replacement that restores that transfer and gets your boiler back to efficient, reliable operation.

This is a professionally refurbished genuine Worcester component, cleaned, pressure-tested, and inspected before dispatch. The 12-plate design is a direct fit across a wide range of Worcester Greenstar i and Si models, with no modification needed for installation.
