If your radiator is not at a level temperature throughout and feels cool at the top and warmer towards the bottom. It could be that gas and/or air is trapped in your radiator, stopping it from heating the radiator fully. You can fix this yourself without having to call anyone out like a plumber/central heating technician. This will save you a bit of cash and it doesn’t take very long. Doing this you will realise how much of a difference it will make to the efficiency of your radiators in your home (this in turn will save you a bit of cash also).
This is a safe way to bleed your own radiators and it doesn’t take that long!
- Firstly, you need to turn the heating on and get all the radiators on and working. You may need to go round to each radiator individually and turn them up.
- Once the radiators are all going, check each one to see if the entire radiator is heating up. Careful not to scold yourself. Make a note of which ones are not heating up correctly. Which ones have cool spots, these are the ones that will need to be bled.
- Then before you start bleeding the radiators, TURN OFF THE CENTRAL HEATING! This is an important step!
- To bleed older radiators you need a radiator key, but you can use a flat head screw driver with newer or more modern radiators. If you don’t have a radiator key, you can pick them up at a good DIY store.
- Locate the Bleed valve, this is mainly found on one side of the radiator. You will need to protect the area and yourself, so put a cloth or a bowl under the valve to catch any water.
CAUTION – The water that comes out might be hot. So you might want to protect your hands.
- Insert the key into the bleed valve, turn it (about a ¼ turn) anti clockwise. The air or gas in the radiator will start escaping and you will be able to hear it making a hissing sound. Once water starts leaking out instead of air, this means that all the trapped air or gas has escaped. So re-tighten the valve the other way to close it off.
- Repeat this with each radiator you noted that needs bleeding.
- Then turn your central heating back on. Check on your radiators after a while and each radiator should be heating up all over the radiator.
Enjoy The Warmth!
