What it is

The Ideal plate heat exchanger kit, part 176469, is a 35 kW heat exchanger assembly used across Ideal's combination boiler range. It sits in the heat transfer circuit, moving heat between the burner side and the water in the system. Ideal builds two heat exchanger types into its boilers: the primary, which transfers heat from the burner to the system water and is present in almost all models, and the secondary, which appears on combination boilers and transfers heat between two closed circuits.

Signs this part needs replacing

  • Domestic hot water runs hot then cold, or flow rate drops noticeably
  • Boiler locks out or reports a fault linked to heat transfer or flow
  • Water weeping from the plate stack or its seals
  • Scale or sludge restricting flow, causing noisy operation
  • Overheating or kettling during hot water draw-off

Before you order

  • Check the GC number and model on the boiler data badge against the compatibility list.
  • Cross-reference the alternative part number 1781964 against older stock or documentation.
  • Confirm whether new seals or gaskets are needed for the plate stack before fitting.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
