What it is

The Ideal heat engine kit, part 173517, is a heat exchanger assembly for Ideal domestic boilers. The heat exchanger takes heat from the burner and transfers it to the water in the heating and hot water circuit, making it a core component of the appliance. It is used across the Elise, Icos and Evo ranges.

Signs this part needs replacing

  • The boiler locks out or repeatedly fails to fire.
  • Kettling, banging or rumbling noises coming from the heat exchanger.
  • Heating output or hot water temperature drops below what the appliance should deliver.
  • Water or condensate weeping around the heat exchanger body or its connections.
  • Flue gas readings fall outside the expected range during a service.

Before you order

  • Match the appliance GC number against the compatibility list. Covered GC numbers include 41-399-97, 41-399-98, 41-397-96, 41-397-86, 41-397-93, 41-397-94, 41-397-95, 41-397-83, 41-397-84 and 41-397-85.
  • Check the number on the existing component against 173517, 173809 and 1179508 to confirm the correct replacement.
  • Confirm the boiler model and serial number before ordering, as the same range can use different heat exchanger variants.
