Worcester Heat Exchanger – Refurbished | Part No. 87377017930 / 8716119315

The main heat exchanger transfers heat from the burner to the central heating and hot water circuits — once scaled, leaking, or blocked, boiler efficiency and reliability drop off. The Worcester Heat Exchanger 87377017930 / 8716119315 (Refurbished) is the correct replacement across a very wide span of Greenstar CDI, CDI HE, CDI Classic, and CDI Conventional models, restoring efficient, reliable heat transfer.

This is a professionally refurbished genuine Worcester component, chemically cleaned, rebuilt, and pressure-tested before dispatch. Minor cosmetic marks may be present, consistent with removal from a working boiler. Supplied with a full 12-month warranty.
