What it is

The heat exchanger sub assembly is a factory-built unit that transfers heat from the combustion gases into the appliance water circuit. It is manufactured by Ideal for the Ideal Commercial range and is supplied as a complete sub assembly rather than as individual plates or sections. In service it forms the primary heat transfer component of the appliance, so its condition directly affects heating output, hot water performance and combustion readings.

Signs this part needs replacing

  • Falling heating or hot water output that cannot be traced to the burner, gas valve or pump
  • Kettling, banging or rumbling noises from the appliance during firing
  • Repeated overheat lockouts or high limit trips on the appliance
  • Water weeping from the heat exchanger body, joints or seals
  • Combustion readings that drift outside the expected range after servicing

Before you order

  • Confirm the appliance model and serial number against the compatibility list, as the sub assembly is specific to the Imax Xtra F160-320 family.
  • Check the part number on the existing component and cross-reference it with 1782150 before ordering.
  • Inspect the mating gaskets and seals while the appliance is open and replace them if they show signs of hardening or damage.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
