What it is
The Alpha 3.023476 is a complete pump group assembly for Alpha gas boilers. It circulates water through the heating and hot water circuits, and is supplied as a full group rather than a bare pump head. It is used across the Alpha ECO 2 and InTEC 2 appliance families.
Signs this part needs replacing
- No heating or hot water despite the boiler firing
- The pump is not running or does not respond to demand
- Unusual noise or vibration from the pump area
- Water leaking from the pump body or its connections
- Boiler locking out on a circulation-related fault
Before you order
- Confirm your appliance model against the fit list above
- Check the part number on the existing pump group before removal
- Verify the appliance family, as ECO 2 and InTEC 2 variants differ
- Work on gas appliances should be carried out by a competent engineer
