What it is

The Ideal 172039 is a complete boiler body with a 14-section heat exchanger, supplied as a replacement assembly for Ideal Commercial Concord ES appliances. It forms the main heat-transfer component of the boiler, where combustion gases pass across the sections and transfer heat into the system water. This is a substantial cast assembly rather than a service part, so it is normally replaced only when the existing body has failed.

Signs this part needs replacing

  • Water weeping from the heat exchanger sections or the section joints
  • Kettling, banging or rumbling noises during heat-up that persist after descaling
  • Visible corrosion, pitting or cracking on the cast sections
  • Poor heat output or the boiler failing to reach temperature despite correct burner operation
  • Repeated lockouts or overheat trips traced to restricted or damaged waterways

Before you order

  • Confirm the appliance model and serial number against the compatibility list, as the body suits Concord ES commercial units only
  • Cross-check the previous number 8358-5505 and the alternative number 1178425 against the unit being worked on
  • Check the sealing arrangements and any gaskets required for the joint faces before starting the swap
  • Work on the appliance should be carried out by a competent engineer, with the gas and water supplies isolated first
