What it is

The Biasi thermostat bulb fixing clamp (BI1105108) is a small retaining component used on Biasi gas boilers. It holds the thermostat sensing bulb in position so the bulb stays in contact with the point it is monitoring. Without a secure clamp, the bulb can move and the boiler's temperature control becomes unreliable.

Signs this part needs replacing

  • The clamp is cracked, snapped or no longer grips the thermostat bulb
  • The sensing bulb is loose and can be moved by hand
  • The boiler short cycles, overheats or gives unstable temperature readings because the bulb has shifted
  • Corrosion or heat damage is visible on the clamp
  • The clamp is missing altogether after previous work on the appliance

Before you order

  • Check your boiler model against the fit list above before ordering
  • Confirm the part number on your appliance matches BI1105108
  • Compare the clamp against the one removed to confirm it is the correct fixing for your thermostat bulb
