Vaillant Main Heat Exchanger – Refurbished, 14cm | Part No. 065180

The main heat exchanger allows heat to transfer between combustion gases and the water circulating through your boiler — once it's worn or scaled, heating efficiency drops off. The Vaillant Main Heat Exchanger 065180 (Refurbished, 14cm) is the correct replacement for the Ecomax Pro 18/28 E and Ecotec Plus 415/428/438 ranges, restoring reliable, efficient heat transfer.

This is a professionally refurbished genuine Vaillant component, quality-checked by experienced engineers. Minor cosmetic marks may be present, consistent with removal from a working boiler. Supplied with a full 12-month warranty.
