What it is

The Hamworthy 563203015S is a heat exchanger assembly for the Wessex Modumax 110 boiler. It is the component that transfers heat from the combustion side into the appliance water circuit. It is supplied as a complete assembly under the Hamworthy part number 563203015S.

Signs this part needs replacing

  • Water loss or visible weeping around the heat exchanger body or its connections
  • Kettling, banging or rumbling noises from the appliance during operation
  • Reduced heating or hot water output that cannot be traced to other components
  • Visible corrosion, scale build-up or distortion on the heat exchanger
  • Repeated overheat or high-limit lockouts linked to poor heat transfer

Before you order

  • Confirm the appliance model is the Wessex Modumax 110 before ordering
  • Check the part number on the existing component or against the manufacturer's parts list for your appliance
  • Check whether any gaskets, seals or fixings are required separately, as these are not confirmed as included
  • Assess system water quality and treat as needed before fitting a new heat exchanger
