What it is

The Baxi 5142018 is a first (primary) heat exchanger supplied together with its gasket. The primary heat exchanger is the component that transfers heat from the combustion circuit into the domestic heating water in a gas boiler. This listing covers the exchanger body and the gasket that seals it on installation.

Before you order

  • Confirm the part number 5142018 against the appliance data badge or the manufacturer's parts listing.
  • Check that the gasket supplied suits the mating face on your appliance before fitting.
  • Verify the exchanger type required, as first and second heat exchangers are separate components.
  • Retain the existing fixings and connections for reuse unless the manufacturer specifies otherwise.
