What it is

The HEAT EXCHANGER ASSEMBLY DUOZ 105 is the primary heat exchanger assembly manufactured by Potterton Commercial for the DuoZ 105 boiler platform. It transfers heat from the combustion gases to the water circuit, forming the core of the boiler's heat transfer path. This is a boiler heat exchanger component supplied under part number 5132214.

Signs this part needs replacing

  • Repeated overheat lockouts or high limit trips during normal operation.
  • Kettling, banging or rumbling noises from the boiler as it heats up.
  • Visible leaks, weeping joints or staining around the heat exchanger body.
  • Reduced heating or hot water performance with the burner firing correctly.
  • Discoloured or scaled exchanger surfaces found during inspection or service.

Before you order

  • Confirm the appliance model against the fitment list before ordering.
  • Verify the existing part number 5132214 matches the component being replaced.
  • Check whether the boiler is a Sirius FS 90-105 or Sirius Wh110 variant, as fitment differs.
  • Inspect associated seals, gaskets and connections for condition before refitting.
