What it is

The Glow-worm 0020014161 is an automatic air vent used on a range of Glow-worm gas boilers. It continuously releases trapped air from the heating circuit, helping to keep water flow stable and preventing air locks within the appliance. This part supersedes 47856.

Signs this part needs replacing

  • Gurgling or bubbling noises from the boiler during operation
  • Air continually present in the system despite repeated venting
  • Water weeping or dripping from the vent body
  • Radiators or the boiler failing to clear air, causing uneven heat
  • System pressure that will not hold steady

Before you order

  • Confirm your boiler model against the fitment list above
  • Check the part number on the existing vent matches 0020014161 or the superseded number 47856
  • Isolate the appliance and depressurise the system before removal
  • Inspect the vent seating and connection point for damage before fitting the new part
