Potterton Gold Heat / Promax Main Heat Exchanger – Refurbished | Part No. 242497

A failing main heat exchanger is one of the most common reasons a Potterton Gold Heat or Promax combi stops delivering hot water or heating efficiently — scaling, leaks, or a blocked waterway all reduce heat transfer and can trigger lockouts. The Potterton Main Heat Exchanger 242497 (Refurbished) is the correct replacement across the Gold and Promax ranges, restoring fast, even heat transfer and reliable boiler performance.

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