How to Bleed a Radiator in 4 Easy Steps
It’s getting colder outside unfortunately so its now time to start turning on the radiators, as they haven’t been on in many months due to this summers heatwave they may experience some issues, which means that they may need bleeding. So we have put together an easy 4 step guide on how to do this.
Turn Your Heating On
The first step of bleeding your radiators is to turn on the heating so that all radiators in your home come on. You should remember to wait until your radiators are fully heated before moving on to step two as you will need to build up the pressure inside the radiator to be able to get all the air out of them.
Check the Radiators Temperature
Once your radiators are hot, you should go and check each radiator and see if every part of them is warming up properly. Be careful though, radiators can obviously get very hot and you could burn/injure yourself when touching them. If there are cold spots on the radiator, (usually toward the top of the radiator) then there could be air or gas trapped, this means you’ll need to bleed that radiator.
Time to Bleed the Radiators
Next, you need to switch off your central heating. You need to do this so you can safely handle the radiators without burning yourself or getting the floor wet when bleeding them.
When bleeding a radiator, you will need a radiator key. If you do not have one, you can buy one to hand you can purchase one at most local hardware stores, or you could use a large flat-blade screwdriver.
At the top of the radiator at one end, there will be a valve. You can attach the radiator key to the centre or put the end of the screwdriver into the groove. Hold the key or screwdriver with a cloth, and have another cloth ready to catch any drips, then slowly turn the radiator key or screwdriver anti-clockwise. If the gas is escaping, you will hear a hissing sound. Once there is no more gas, a liquid will come out and the valve will need to be closed quickly.
Check The Pressure
Finally, you should check the pressure of the radiators. You can do this by having a look at the gauge on your boiler. If the pressure is too low, you’ll need to top it up. You can do this using the lever or tap on your boiler, known as the filling loop.
Afterwards, you may want to run another ‘hot test’ to check that the radiator is heating evenly and properly. Simply turn your heating on, wait for all the radiators to heat up and check for any cool spots.
