What it is
The Biasi BI1141505 is a by-pass kit for Biasi gas boilers. It forms part of the hydraulic circuit, allowing a controlled flow path around the heating circuit so system differential pressure stays within the boiler's operating range. It is used across the Biasi Garda, Parva and RIVA HE appliance families.
Signs this part needs replacing
- Boiler short-cycling or failing to hold a steady flow temperature
- Excessive noise from the hydraulic circuit during heating operation
- Radiators heating when only hot water is demanded
- Poor differential pressure control across the heating circuit
- Visible damage, blockage or scale build-up in the by-pass assembly
Before you order
- Confirm your boiler model against the fitment list above
- Check the existing by-pass assembly for damage or blockage before ordering
- Verify the part number BI1141505 matches the component being replaced
- If unsure of the correct part for your appliance, consult the manufacturer's parts list
