What it is
The Ideal 175160 is a heat engine kit — the primary heat exchanger assembly used across the Ideal Isar HE, Icos System MV3 and related boiler ranges. It sits in the combustion path and transfers heat from the burner gases into the system water that serves the radiators and hot water circuit. The kit is supplied as a complete heat engine unit for direct replacement of the original assembly.
Signs this part needs replacing
- The boiler locks out or fails to fire reliably, with repeated ignition or flame faults.
- Heating or hot water output drops noticeably, or the appliance struggles to reach temperature.
- Kettling, banging or rumbling noises coming from the heat exchanger during operation.
- Water weeping from the heat engine body, its seals or the surrounding pipework joints.
- Overheat faults or a heat exchanger that is scaled or sludged and cannot be cleared by flushing.
Before you order
- Check the GC number on the appliance data badge against the compatibility list below before ordering.
- Confirm the exact model and, where available, the serial number, as appliances in the same range can use different heat engines.
- Order replacement seals or gaskets where the existing ones will be disturbed during removal and refitting.
