What it is

The Buderus 73032 is a heat exchanger used in Buderus oil-fired boilers. It transfers heat from the combustion gases into the boiler water circuit, forming the primary heat transfer component of the appliance. This part is listed for the Buderus 800-43.

Signs this part needs replacing

  • Water weeping or visible staining around the heat exchanger body or its connections
  • Soot or combustion deposits building up on the heat exchanger surfaces
  • Reduced heat output to the heating circuit or domestic hot water
  • Kettling, banging or gurgling noises from the boiler during operation
  • Corrosion, pitting or scale build-up on the heat exchanger casting

Before you order

  • Confirm the appliance model is Buderus 800-43 and check the GC number against the boiler data plate
  • Check the existing part number against the manufacturer's parts list for your appliance
  • Inspect the surrounding seals, gaskets and connections, as these may also need attention during replacement
  • Confirm the boiler is isolated and drained before any work begins
