What it is
The Baxi 5142012 is a first heat exchanger supplied together with its gasket. It forms the primary heat transfer stage of the appliance, where heat from combustion is passed into the system water circuit, and the accompanying gasket seals the mating face on reassembly.
Before you order
- Confirm the part number 5142012 against the appliance's own data badge or service documentation before ordering.
- Check whether the existing gasket is reusable; a heat exchanger is normally refitted with a new sealing gasket.
- Verify that the appliance's primary circuit is fully drained and isolated before any strip-down work begins.
