What it is

The Ideal 172037 is a complete boiler body with 11 sections, supplied as a heat exchanger assembly for Ideal Commercial Concord appliances. It forms the cast iron heat exchanger core of the boiler, where heat from combustion passes through the sections into the water circuit. Because it is the full body rather than a single section, it replaces the entire heat exchanger block in one operation.

Signs this part needs replacing

  • Water weeping from the heat exchanger casting or from the joints between sections
  • Visible corrosion, cracking or heavy scale build-up across the sections
  • Kettling, banging or rumbling noises while the boiler is firing
  • Repeated pressure loss with no external leak traced elsewhere on the system
  • Reduced heat output or a poor temperature rise across the boiler

Before you order

  • Confirm the appliance model and GC number against the compatibility list before ordering.
  • Check the previous number 8358-5503 and the alternative number 1178423 to confirm this body matches the unit being repaired.
  • Check whether section joint gaskets or seals need replacing at the same time as the body.
  • Allow for the weight and size of a complete 11-section body when planning the removal and refit.
