To find out how to bleed your radiators, keep reading...Spot the problemBefore you think about bleeding your radiators you need to have a reason to do so. All systems will occasionally need bleeding but some signs to look out for include cold spots, or your radiators taking a long time to heat up.Check all radiatorsIf you have noticed a problem with one, it is a good idea to fire up your system and check the others too. See how long they take to warm up and feel for any inconsistencies with temperature. If you find any other problems, you should bleed these radiators too.Turn the central heating offYou must switch off your heating, or the job will become a lot messier than it needs to be. If the heating is left on, you will be left with a puddle of water when you open the valve.Release the trapped airThis is the main step with bleeding your radiators. You need a radiator key (available cheaply online or in any DIY shop) and an old rag or tea towel. Fit the key to the valve at the top of the radiator, using the rag to catch any drips and protect your hands. When the key is fitted, begin twisting it anti-clockwise to let the air escape.Close the valveWhen the valve is open, you will be able to hear the air escaping. When the noise becomes less, water will be moving towards the hole. When all the air has gone and you feel the water coming, close the valve quickly to reduce the amount of water that pours out.Check the pressureWhen the radiator has been bled, you need to check the pressure gauge on your boiler. If the pressure is now too low, you need to top it up. Adjust it using the filling loop and the instructions from your manufacturer.Need a boiler specialist in West Sussex?Our boiler services are based in Rustington, West Sussex- but we also cover Angmering, East Preston, Ferring, Littlehampton, Arundel, Worthing and the rest of the South Coast, including Brighton and Chichester.
