What it is
The Alpha 1.027178 is a replacement fan assembly for Alpha InTEC and Eco boiler ranges. It sits in the combustion circuit and drives air into the burner while pushing flue gases out through the flue system, so the boiler can maintain a stable, correctly balanced burn. The assembly is supplied as a complete fan unit rather than a bare impeller, which makes it a direct swap for a failed or noisy original.
Signs this part needs replacing
- Grinding, whining or rumbling noise from the fan area during or after ignition
- Boiler locking out shortly after start-up, often with a fan-related fault code
- Repeated ignition failures where the burner lights and then drops out
- Overheating or poor combustion performance traced to restricted air movement
- Visible damage, stiffness or play when the fan is turned by hand
Before you order
- Check the GC number on the appliance data badge against the compatibility list to confirm the correct fan variant
- Compare the part number on the existing fan with 1.027178 and the alternative numbers 1258307 and 027178
- Confirm the boiler model and, where relevant, whether it is the LPG or natural gas version
