Bleeding The Boiler

  1. Set radiator to the maximum heat setting and ensure the boilerbegins to circulate water.
  2. Turn off your central heating unit to stop airflow or waterfrom being pumped through the unit.
  3. The radiator closest to the heating boiler needs to be turnedoff using the valve.

Similarly, will an airlock clear itself? Well, it's because there's an airlock in yourtap. Basically, because air is lighter than water, it canoften get trapped in all the twists and bends of your home's waternetwork. All you have to do is blast out the air lock forfreely flowing pipes… and it only takes fiveminutes.

The main cause of an air lock in pipes iswhen pockets of air are trapped by the flowing water,preventing the free flow of water. Also, cold water pipeshave less pressure compared to the hot water pipes; as aresult, it's mainly hot water pipes that are affected byair locks.

What happens if I bleed my radiators with the heating on?

Radiators need bleeding when pockets ofair get trapped inside. The air causes the radiator tocirculate hot water less effectively and so less heat isemitted, meaning it will take longer to heat your home. Coldspots are an indicator of trapped air, and so you'll need tobleed any radiators on which you do findthem.

Mack Hartelt


Should water come out when bleeding radiators?

Feel all over your radiators for heat and don'tattempt to bleed them if they're still warm. You don't wantboiling water to spurt out when you open the valve,for starters. But secondly, it's good to let your radiator'scontents settle completely before you start, to make yourbleeding really effective.

Does bleeding radiators affect boiler pressure?

Bleeding radiators
If you bled your radiators recently, youmay have lost some pressure. That's because, when youbleed a radiator, air is released, which lowers thepressure in your boiler system.
