Baxi 248048 16 Plate Heat Exchanger – Refurbished | Replaces 7225723

A Baxi, Potterton, or Main combi boiler that's lost hot water consistency often points to a plate heat exchanger that's no longer transferring heat efficiently between the domestic hot water and primary heating circuits. The Baxi 248048 Plate Heat Exchanger, 16 Plates, is the genuine replacement that restores that transfer — and it's now officially superseded by part number 7225723, so this is the direct fit for older units still carrying the original 248048 reference.

This is a professionally refurbished component, fully cleaned, pressure-tested, and sealed before dispatch, giving you manufacturer-grade performance at a fraction of the cost of buying new. The 16-plate stainless steel design is a direct fit across the compatible range, with no modification needed for installation.
