Alpha Intec 2 12 Plate Heat Exchanger – Refurbished | Part No. 3.021692

Inconsistent hot water temperature, weak flow, or a combi boiler that struggles to keep up with demand are classic symptoms of a tired plate heat exchanger. This component sits at the heart of the heat transfer process between the primary heating circuit and the domestic hot water circuit, so once it scales up or wears internally, performance drops off noticeably. The Alpha 12 Plate Heat Exchanger, Part No. 3.021692, is the genuine like-for-like replacement that restores that transfer and gets your hot water back to where it should be.

This is a professionally refurbished genuine Alpha component. Every unit is stripped down, cleaned, descaled, and pressure-tested before it's cleared for dispatch, so you get manufacturer-grade performance without paying new-part prices. The 12-plate design is a direct fit for the relevant Alpha Intec range, with no modification needed for a straightforward swap.
