What it is

The Ideal 172042 is a complete 20-section boiler body assembly, forming the heat exchanger core of the appliance. Ideal builds it for the Ideal Commercial Concord ES range, where it carries heat from combustion into the system water. It is supplied as a full body rather than individual sections, so the whole stack is renewed in one operation.

Signs this part needs replacing

  • Water weeping from the body or from the joints between sections
  • System pressure falling repeatedly and needing regular topping up
  • Corrosion, scale build-up or rust staining across the section stack
  • Kettling, banging or rumbling noises as the boiler fires
  • Overheating, lockout or poor heat output where the body is restricted or blocked

Before you order

  • Confirm the appliance model and, where shown, the GC number against the compatibility list before ordering.
  • Check the number on the existing body, as earlier builds may carry 8358-5508.
  • Check whether new gaskets, seals or fittings are needed for the swap and order them alongside the body.
