What it is

The Biasi return group plug with NTC (part BI1181104) is a boiler component that combines the return group plug with an NTC temperature sensor. It is listed by Biasi under gas boiler spares and is used across a number of Activ A, RIVA and Parva appliances.

Signs this part needs replacing

  • Boiler locks out or fails to fire, with an NTC-related fault code
  • Heating or hot water temperature reads incorrectly or fluctuates
  • Boiler cycles or modulates erratically
  • Intermittent shutdowns once the appliance reaches temperature
  • Sensor resistance readings outside the manufacturer's expected range

Before you order

  • Confirm your boiler model and GC number against the list above
  • Check that part number BI1181104 matches the item removed
  • Verify the fault lies with the NTC sensor before replacing the plug
