My central heating works great apart from one radiator. It needs bleeding as the bottom is warm but the top is cold. I cannot turn the bleed valve on it. i tried to use a pair of pliers to get a better grip of it but all this did was erode the metal of the valve. i am turning it the right way as i have bled other radiators in my house without a problem.i have used one of those key things to try to turn it but because i have forced the valve with pliers the key just turns without turning the valve.Please help as my bedroom is getting colder! Thanku everyone in advance.

Turn off the valves each end, may need pliers, remove the nut that holds the bleed screw, there will be a little water, take the nut and bleed screw to a plumbers merchants, get the replacement re-fit in reverse, you will need ptfe tape if new nut does not have a rubber seal.

Radiator Bleed Valves

Difficult. You may be able to replace the whole bleed valve by turning off both radiator valves and then unscrewing the bleed valve with a spanner. Have a large old towel handy as there will be a few drips. Some radiators do not seem to have replaceable bleed valves, in which case its a new radiator. Unless you want to go for last chance option of using Araldite between key and valve, being careful that it only contacts valve shaft and key interior. You will need a new bleed key after this !!

If the bleed valve is a separate part as most modern radiators are then its a simple case of just changing the whole bleed valve plug.Cost about £1 from a plumbers merchant and come in two sizes1\4 and 1\2 gas thread. If the bleed valve is a welded part of the radiator then its a new rad !! You should be able to get one the same size but it might not be exactly the same wall fixings. You might want to take this chance and get a new radiator that is the correct size for the room. Ask your local merchant to calculate the correct size for you.

If the radiator is simple and there is some give in the plumbing risers you may be able to bleed it by loosening the tail connectors at the valves and then lifting the radiator off the bracket and rotating the top down to the floor. Then loosen the top of the tail valve to let out the air.
Possibly you can non-destructively loosen the bleed valve by striking it sharply and squarely with a hammer and mechanics punch and then loosening it with needle-nosed pliers.
Other than that you may need to remove the bleed valve by drilling it and using a small screw extractor. You might find a replacement bleed valve in a discarded rad at your local tip.

ooops!!!
shudna dun it son.
if your in the UK you can get a new rad for about £20 for a 500mm x 600mm double.
Focus,do it all and b&q all do a good cheap range.
job time 30 mins with the right tools (plyers dont figure any where in the process,,lol)
turn off the thermostat on the rad and then the flow tap on the other side.
take a 17mm spanner and open the couplings on the rad side of the fitting.
not forgetting to put a bowl or other water catching implement under the coupling as you loosen it to drain off the water.
once removed take outside and dispose.
build up the new rad as per the instructions supplied.
line up and mark for the new brackets
fit new brackets then mount the rad (dont forget to use PTFE tape on all fittings, 6 turns clockwise).
once couplings are reconected open both taps.
open bleed screw and run till you have got rid of all the air.
turn on central heating and enjoy a warm room.
have fun, DIY is so rewarding

If you've shaved the edges off the valve try this old trick to get it to turn.
Get a matchstick and shove it into the end of the key, if the breadth of the matchstick is too wide, just bite it to flatten it a bit, place the key with the piece of matchstick in over the valve and turn slowly.

You do not need to buy a new rad. Just get a spanner and slowly open the nut on the other end of the rad and vent the air out from there. Close tight afterwards.

see the nut shaped end piece at the top, just put a spanner on it an adjustable will do and turn that instead of using the bleed valve part

The buggers stuck!! You might be as well to get a new radiator, they're not expensive and trying to fix the stuck one will probably be more trouble than its worth.
