What it is

The Hamworthy 563203012S is a heat exchanger assembly supplied by Hamworthy for use in Wessex Modumax 120 appliances. The heat exchanger transfers heat from the combustion circuit into the appliance water circuit, making it central to both heating and hot water performance. It is a serviceable assembly rather than a single component, so it is replaced as a unit.

Signs this part needs replacing

  • Reduced heating or hot water output despite the appliance firing correctly
  • Kettling, banging or gurgling noises from the heat exchanger during operation
  • Water weeping or staining around the heat exchanger body or its connections
  • Repeated overheating faults or lockouts linked to poor heat transfer
  • Visible scale, corrosion or debris build-up restricting flow through the exchanger

Before you order

  • Confirm the appliance model is Wessex Modumax 120 before ordering
  • Check the existing part number against the manufacturer's parts list for your appliance
  • Inspect associated seals, washers and connections, as these are not confirmed as part of this assembly
  • Work on the heat exchanger and combustion circuit should be carried out by a competent heating engineer
