Everybody loves this question, because they all give something resembling a right answer, it is the stock answer for a heating problem from people who know little about heating, but, as I said, they are all right! Turn off the heating, leave 20 mins to cool and settle, using a bleed/vent key, (if you don't have one, your neighbour will) vent the radiators, start downstairs work your way up, if you have a combination or system boiler, you will need to top up the pressure.

Yes most of the answers you have received are correct. However, the one thing that you must make sure you do is to turn off the heating pump before you try to bleed the radiators. If you don't do this there is a likelyhood that air will be drawn in as you open the bleed valves on the radiators. If you don't know how to turn off the pump, just turn off the boiler until you have finished bleeding all the rads. Good Luck!

Air in the system, get a bleed key find the little diddle it fits into this'll be at the left or side side of your radiator at the top then use the key to open it, you'll hear a whooshing noise as the air comes out but be careful not to open it too far because after the air comes out the water will too. Once all the air has gone shut the little valve thingie & away you go. Oh & apparently you should start at the top of your house & work your way down.

there is air in your radiators, so the water is at the bottom and and that's what is heated. all you need to do is bleed them. you will have a key somewhere which can be used to do this. just place it in the key hole which will be at the bottom of the radiator on the opposite side to the temperature adjuster. turn the key and you will hear it hiss, this is the air. be careful though as you may let the water out if you leave it too long, best to put some towels down just in case.

There is air trapped in the radiator. You need to get a bleeding key from most hardware stores and turn the key at the top of the radiator until all the air is out. Make sure you have a towel under your hand as once the air is out, you will get some very dirt water coming out. You then need to re-tighten the key. This should sort it.

This suggests the radiator has air within it and requires draining, by turning the key on the drain at the top end of the radiator. Suggest all are done.

Full of trapped air at the top. The hot water can't fill the radiator. They need 'bleeding' with a radiator key

Because the water level inside them has fallen and air is trapped at the top. You have to bleed the air out. If you haven't got one, the local hardware shop will not think that you are rude if you ask for a radiator bleeding key, They cost around £2. Use the key carefully on the square knob at the top of the radiator, turning it slowly anticlockwise. You will hear air hissing out and when it changes to water lock the knob clockwise. Its best to hold a cup under the key so that the water does not squirt onto the floor.

Let the trapped gas out through the bleed-screw located on the top end of the rad,
The chances are that the installer did'nt put "inhibitor" in when installing.. and the steel of the rad. is being eaten-away by the slightly acidic water.
Pay £ 50 and have it injected with Fernox or Sentinel.
