What it is
A complete heat exchanger for Cannon Misermatic K26 appliances. The heat exchanger transfers heat from the combustion side into the system water, so it sits at the centre of the boiler's operation. This is the complete assembly as listed by Cannon for the Misermatic K26 range.
Signs this part needs replacing
- Water loss or visible staining around the heat exchanger body or its connections
- Kettling, banging or rumbling noises from the appliance during heat-up
- Repeated overheating, overheat lockout or the appliance cutting out before reaching temperature
- Poor or inconsistent heating and hot water performance with no other obvious cause
- Soot deposits, discolouration or combustion readings that cannot be corrected by servicing
Before you order
- Confirm the appliance is a Cannon Misermatic K26 and identify whether it is the Mahogany or TEAK variant
- Check the model and GC number on the appliance data badge against the listing before ordering
- Inspect the surrounding pipework and seals, as these may also need attention when the heat exchanger is replaced
- Confirm the system has been drained and isolated before any work begins
