Description

Baxi Heat Exchanger 248723| DHW 22 Plate

This listing is for a Baxi domestic hot water (DHW) heat exchanger, current part number 7223558, which replaces the older part number 248723 following a manufacturer update.

The DHW heat exchanger transfers heat from the boiler’s primary circuit into your domestic hot water supply. Over time, limescale and debris can block the internal plates, causing reduced hot water flow, fluctuating temperatures, or boiler fault codes.

This 22-plate DHW heat exchanger restores correct hot water performance when fitted by a qualified engineer.
