If you find that the radiators in your home are not heating up properly, or that they are cold at the top and warm at the bottom, this is a sign that they need to be bled. When this has been done, it allows hot water to circulate through your heating system once more.
It might seem like a stressful and complicated process, but the good news is that it’s very simple. Most radiators are going to need it at some point, so instead of stressing and asking how do you bleed a radiator, check out our instructions below and get it done in minutes.
How to Bleed a Radiator in Steps
In order to bleed a radiator you will need:
• A radiator bleed key (or a flathead screwdriver)
• An old cloth or a basin to catch the water1. Make sure the central heating is off and the radiators are cold
1. Place the cloth or basin under the bleed valve and insert the key
2. Turn the key anticlockwise until you hear the hissing of escaping air
3. When the water starts to escape, turn the key clockwise to close the valve
4. Repeat the process on any other radiators that need it
5. Turn the heating back on and check the radiators are working correctly
Top Tip: If you are bleeding multiple radiators, start from the one that is furthest away from the boiler. Similarly, you should start with radiators that are downstairs before heading upstairs.
How Do You Know Your Radiator Needs Bleeding?
There are a couple of ways to tell if your radiator needs bleeding. It might be taking longer than usual to heat up, the top might feel cold while the bottom is warm, or you could be hearing gurgling sounds when the radiators are on.
Why Do You Bleed Your Radiator?
When you bleed your radiator, you are removing the air pockets that prevent hot water from circulating your central heating system effectively. It puts a great deal of strain on your boiler and also ends up costing you more money. Bleeding the radiators can be done within a few seconds and you don’t have to be a professional to get it done.
If bleeding your radiators doesn’t work, it is likely that your central heating system will need to be drained and flushed instead. This is a different process entirely and it is highly recommended that you have a professional come and do this if it is required.
How Often Should You Bleed a Radiator?
It is a good idea to bleed your radiators once a year as this means you are keeping on top of their maintenance and checking that they are working correctly. The best time to do it is in the autumn so that you can get them ready for regular use in the winter months. If you find you need to bleed your radiators once a year you should contact a plumber right away.
To Conclude
It’s simple as anything, and you are sure to have the heating back and working in no time at all. The best part is that you don’t really need any tools, and it doesn’t take a great deal of time or effort. Of course, there could be cases where your heating system needs more than just a radiator bleed but this should be the right solution most of the time.
