- Reduced hot water output compared with the appliance's normal performance
- Water weeping or staining around the heat exchanger body or its connections
- Kettling, banging or rumbling noises from the heat exchanger during demand
- Scale or debris build-up restricting flow through the secondary circuit
Before you order
- Check the boiler rating plate and confirm your model matches one of the fit lines listed above
- Confirm the part number 87186819040 against the manufacturer's parts list for your appliance
- Establish whether the complete final assembly is required or a separate component of the secondary circuit
- Investigate the condition of the system water, as scale and debris are common causes of secondary heat exchanger failure
