An easy and cheap fix for combatting cold and patchy radiators, bleeding a radiator is something anyone can do in their own home without the need for a heating or plumbing engineer.
Radiators become less effective the more gas there is trapped within them. Bleeding your radiators will release the trapped air allowing the hot water to circulate freely.
Enabling you to heat your home more effectively and efficiently, bleeding your radiators regularly is an important part of maintaining your central heating system.
Before you do anything you’ll need to ensure that your central heating and hot water are switched off at the boiler. This will enable you to handle your radiators safely.
Once you’ve closed your radiator valves, it’s safe to turn your central heating and hot water back on. If you’ve been successful your radiators should start to heat up within a few minutes.
You can also check the pressure gauge on your boiler and check that it reads between 1-1.5 bar.
Depending on what type of radiators you have in your home, it may be possible to bleed them automatically using an auto vent. These handy devices are attached to your radiator valves and let out air gradually over time. Helping to keep your radiators working efficiently, with an auto vent you won’t need to bleed them manually.
