What it is
The Biasi BI1441103 is a return group assembly used on Biasi condensing gas boilers. It forms the return side of the boiler's hydraulic circuit, where water returning from the heating system re-enters the appliance. This version is specified for units produced from May 2011 onwards.
Signs this part needs replacing
- Water weeping or visible staining around the return connection on the boiler
- Loss of system pressure that cannot be traced to any other part of the circuit
- Corrosion or scale build-up on the return pipework or its fittings
- Overheating or poor circulation traceable to a restricted return path
- Noise or vibration from the return side during operation
Before you order
- Confirm the boiler model and check the appliance data plate against the fit list above
- Check the boiler's manufacture date, as this version is intended for units built from May 2011
- Verify the existing return group's part number before removing it
- Inspect the surrounding pipework and seals for condition while access is available
