What it is

The Ideal automatic air vent is a pressure safety device fitted within the central heating unit. A float inside the body rises and falls with the water level, opening to discharge accumulated air and closing again once the system is free of it. Ideal supplies this vent for use across their British and Scottish Gas appliance range.

Signs this part needs replacing

  • Gurgling, bubbling or rushing noises from the boiler or pipework as air moves through the system
  • Radiators that need bleeding repeatedly, or cold spots at the top of the panels
  • Water weeping or dripping from the vent body or the surrounding casing
  • System pressure falling without a visible leak elsewhere on the circuit
  • The vent failing to discharge air even when the system is clearly airlocked

Before you order

  • Check the GC number on the appliance data badge against the compatibility list below.
  • Confirm the existing vent is marked 113116 or carries the alternative number 1175709.
  • Check whether the vent seal or gasket also needs renewing at the same time.
