What it is

The Ideal 174403 is a heat exchanger sub assembly manufactured by Ideal for its commercial boiler range. It forms the primary heat transfer component, taking heat from the combustion gases and passing it into the system water circuit. This sub assembly is built for the Imax Xtra F280 to F560 family of commercial appliances, where it sits at the centre of the boiler's hydraulic and combustion path.

Signs this part needs replacing

  • Water weeping or staining around the heat exchanger body or its connections
  • Kettling, banging or rumbling noises from the appliance during firing
  • Repeated overheat lockouts or high flow temperature faults
  • Falling flow and return temperature differential with the burner at full rate
  • Combustion readings drifting outside the expected range for the appliance

Before you order

  • Confirm the appliance model and serial number against the compatibility list before ordering, as the sub assembly is specific to the Imax Xtra F280-F560 range.
  • Check the alternative number 1782158 against any documentation supplied with the appliance.
  • Inspect the mating gaskets and seals on removal and replace them where they are disturbed.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
