What it is
The condensing heat exchanger is the primary heat transfer component in Alpha condensing boilers, recovering heat from the flue gases before they are discharged. It is supplied by Alpha under part number 3.027697. The assembly is used across the E-TEC and Evoke LPG ranges.
Signs this part needs replacing
- Water weeping or staining around the heat exchanger body or its connections
- Condensate escaping from the exchanger rather than draining correctly
- Reduced heating output or the boiler struggling to reach temperature
- Kettling, gurgling or unusual noise from the heat exchanger during operation
- Visible corrosion, scale build-up or distortion on the exchanger surfaces
Before you order
- Confirm your boiler model and, where applicable, its GC number against the fitment list
- Check that your appliance is the LPG variant, as this part is listed for LPG models
- Verify the part number on the existing component matches 3.027697
- Inspect associated seals, gaskets and connections for condition before fitting
