Ideal Heat Engine Kit 174130

The Ideal 174130 heat engine kit is a replacement heat exchanger assembly for Ideal Mexico HE series boilers. It sits in the combustion path and transfers heat from the burner gases into the system water, so it is central to how the appliance heats a property. The kit is listed by Ideal under the heat exchangers part type and is supplied for the Mexico HE30 and HE36 range.

• The boiler runs but the heating or hot water output is noticeably weaker than it used to be.
• Kettling, banging or rumbling noises from the appliance as the water boils locally on a scaled or restricted exchanger.
• Repeated overheat lockouts or the boiler cutting out before the system reaches temperature.
• Water weeping from the exchanger body, its joints or the surrounding seals.
• Discoloured system water or sludge build-up found when the exchanger is inspected.

• Confirm the GC number on the appliance data badge against the numbers listed above before ordering.
• Check the exact model name on the boiler, as Mexico HE30 and HE36 variants are listed separately.
• Have the relevant gaskets and seals to hand for the exchanger joint, as these are disturbed during removal and refitting.
