What it is

The Hamworthy 533203005 is a secondary heat exchanger carrying the S70 designation, supplied by Hamworthy for its gas boiler assemblies. It is the component that recovers residual heat from the combustion gases after they leave the primary heat exchanger, transferring that heat into the returning system water. This recovery step lowers the flue gas temperature and raises the overall efficiency of the boiler.

Before you order

  • Confirm the existing component carries the part number 533203005 and the S70 designation before ordering.
  • Check the boiler's installation and service documentation to confirm the correct heat exchanger reference for the appliance.
  • Review the condition of the surrounding pipework, connections and seals at the same time, since access is required for the swap.
