What it is

The Ideal 175161 is a heat engine kit for Ideal domestic boilers. It is the assembly that carries heat away from combustion and into the heating and hot water circuit, so it sits at the centre of the appliance's performance. This version is specified for the Icos HE range built after the WM change point (MV3).

Signs this part needs replacing

  • The boiler fires but the heating circuit or hot water stays cold
  • Kettling, banging or gurgling noises coming from the heat exchanger
  • Repeated lockouts or ignition faults that return after resetting
  • Water weeping from the heat engine housing or its connections
  • System water that turns dark or gritty, indicating internal corrosion of the exchanger

Before you order

  • Check the GC number and model against the compatibility list to confirm the correct variant
  • If you are working from an older reference, note that 175162 is the previous number for this kit
  • Confirm whether a gasket or seal kit is needed for the appliance being repaired
