Bleeding a radiator

  • Turn off the central heating.
  • Insert a radiator bleed key into the bleed vent.
  • Hold a cloth underneath the bleed vent to catch any excess water.
  • Undo the bleed vent in an anti-clockwise direction and to a maximum of one turn. You should hear a hissing noise which is the air escaping.
  • As soon as water starts to appear, turn off the bleed vent by turning it in a clockwise direction – do not over-tighten.
  • Turn on the central heating and recheck the radiator.
