What it is

The Hamworthy 563402843S is a six-section heat exchanger supplied as a spare part for Hamworthy boilers. It transfers heat from the combustion gases to the system water within the appliance. This listing covers the heat exchanger assembly as a service component.

Signs this part needs replacing

  • Water weeping or visible staining around the heat exchanger body or section joints
  • Repeated loss of system pressure with no external leak found elsewhere on the appliance
  • Kettling, banging or rumbling noises from the heat exchanger during firing
  • Poor heat transfer, with the boiler struggling to reach or hold flow temperature
  • Corrosion, scale build-up or distortion visible on the sections

Before you order

  • Confirm the appliance model and that a six-section heat exchanger is the correct unit for it
  • Check the part number 563402843S against the manufacturer's parts list for your boiler
  • Inspect associated seals, gaskets and connections, as these are not confirmed as included
  • Confirm access and lifting arrangements, as a six-section heat exchanger is a heavy component
