What it is
The Biasi BI2445107 is a pressure gauge used on Biasi Advance and Advance PLUS gas boilers. It provides a visual reading of the heating system pressure at the boiler. The gauge is a serviceable component and is replaced when the reading becomes inaccurate, stuck or unreadable.
Signs this part needs replacing
- The needle no longer moves when system pressure changes
- The gauge reads zero or a fixed value regardless of actual pressure
- The dial face is obscured, discoloured or the markings are illegible
- The needle has dropped off its spindle or sits outside the scale
- Moisture or debris is visible behind the gauge lens
Before you order
- Confirm your boiler model against the fitment list above
- Check the existing gauge for the BI2445107 part number where visible
- Verify whether your appliance is the natural gas or LPG variant
- Confirm the fault lies with the gauge rather than the system pressure itself
