What it is
The Alpha 1.028253 is a heat exchanger used in the Alpha CD115S appliance. It transfers heat from the combustion side of the boiler into the domestic water circuit. It is listed by the manufacturer under part number 1.028253.
Signs this part needs replacing
- Water weeping or dripping from the heat exchanger body or its connections
- Repeated overheat or lockout faults traced to restricted flow through the exchanger
- Reduced heating or hot water output that does not recover after flushing
- Visible scale, corrosion or discolouration on the exchanger surfaces
- Combustion readings that fall outside the expected range for the appliance
Before you order
- Confirm the appliance is the CD115S LPG variant, as fitment differs between fuel types
- Check the part number on the existing component against 1.028253
- Verify the fault has been traced to the heat exchanger rather than the pump, diverter or system blockage
