Keeping warm and toasty during the colder months makes a house a home. However, if you notice one of your radiators is cold at the top, it probably means trapped air, which needs to be released.

  • Switch off your heating to prevent scalding yourself or damaging your floor or wall when hot water escapes from the radiator
     
  • Use a radiator key to turn the valve in the top corner of the radiator
     
  • Hold a cloth under the valve to catch any water that escapes from the radiator
     
  • Allow air to hiss out of the valve – once the escaping air is replaced with water, close the valve with the radiator key
     
  • After bleeding your radiators, your boiler may need to be re-pressurised
     
  • Check the pressure gauge on your boiler – if it’s below 1 bar, it’ll need to be topped up with air
     
  • There will be a filling loop valve near the boiler – open this valve to top up the pressure to about 1.5 bar (never go above 2.5 bar)
     
  • Each boiler is different, so please read the manufacturer’s instructions for more precise details
     
  • If a radiator is cold at the bottom and bleeding the radiator didn’t help, it’s likely that debris has collected in the bottom of your radiator.  You’ll need to employ a qualified plumber to remove the radiator and flush this out of the radiator system
