Worcester Bosch Greenstar 16 Plate Heat Exchanger – Refurbished | Part No. 87161066850

When your Worcester Greenstar boiler starts struggling with fluctuating hot water temperatures, reduced DHW flow, or persistent fault codes, a worn or scaled secondary plate heat exchanger is a very common root cause. The Worcester Bosch 16 Plate Heat Exchanger (Part No. 87161066850) is a direct replacement that restores efficient heat transfer between the primary heating circuit and the domestic hot water system, bringing your boiler back to full performance.

This part is available in both Refurbished and Brand-New options. The refurbished version is professionally stripped, cleaned, descaled, and pressure-tested to meet original Worcester Bosch standards. The new version is a compatible 16-plate upgraded design offering improved heat transfer versus lower-plate original configurations. Both options include Worcester seals and carry a 12-month warranty.
