Worcester Greenstar 12 Plate Heat Exchanger (New & Refurbished) | Part No. 87161066860

Please note: manufacturer part number 87161066860 also appears on a separate source listing marketed as a "10 Plate" heat exchanger with a different compatibility list (Greenstar HE/HE Plus/R/RD ranges). See the flag in the summary below before publishing both.

The plate heat exchanger transfers heat quickly between the primary circuit and domestic hot water — scale or wear here often shows up as reduced or fluctuating hot water output. The Worcester Greenstar 12 Plate Heat Exchanger 87161066860 is the correct replacement across the Greenstar i System, Junior HE, Si, and 25i Combi ERP ranges, restoring steady hot water performance. Available in both Refurbished and Brand New condition, so you can match your budget and repair needs.

Refurbished units are taken from a fully functioning boiler and quality-checked by an experienced engineering team; minor cosmetic marks may be present. Both conditions are supplied with a full 12-month warranty.
