The radiator in the attic is only hot at the bottom part of it (not even half is hot). The upper part of the radiator is really cold. I really appreciate if any of you could help me with this problem. Thank you very much!
Please tell me step-by-step solution to overcome this problem. Thanks again!

For once bleeding should solve the problem If you have a combi then put the pressure up to 1.5 bar first. Turn the system off first. If its a normal tanked system and you are unable to get water out of the vent then look at the water level in the header tank ball valve may be stuck. If still no success poke vent hole out with a pin but beware of water squirting out.

Its got air in it and needs 'bleeding'. This is simple to do, but ONLY if you have a radiator key. If not, don't attempt to do it. You put the key in the special place at the top (side) of the rad and turn it gently and the air hisses out. You stop and turn the key back quickly when drops of water start to come out. If you have never done this before or you don't think the rad has been bled before, then i dont think you should attempt it alone even if you have a rad key. Once i did one in my daughter's bedroom and then i couldnt turn it back off, cos a little 'inside bit' had gone wobbly. So that meant i had water pouring out of the rad. Not funny! Seriously bad! So don't go there without assistance. You may need one person to hold a towel on it and one to call a plumber! Rads do need bleeding or else you will find the whole system is not as efficient as it should be.

Probably has air in the radiator. Just get a key to open the radiator (if you look at the top corners one of them should have a small square bit) If you are lucky you may just need a screwdriver.
Open this valve slowly and you should hear air escaping from it let this go until water starts to come out and quickly close it. Make sure you wipe up anything spilled as there may be an additive added to the water that could be nasty.

It sounds like you have air in the radiator. On the top of the radiator you will see a square type nut. Get yourself a cloth and a radiator key. Turn the key until you hear hissing, this is air leaving the radiator. Get ready with your cloth and as soon as water replaces air leaving the radiator turn the key clockwise . The radiator should now become hot all the way through.

Air. 'Bleed' the top with a radiator key until water comes out.
You'll find a small square nut at the top (usually top left or right of rad) of the radiator, undo this half a turn with a radiator key, or until you hear air coming out. Wait until water comes out and then quickly tighten up again.
You'll need a rag to catch water, water might be dirty, hold with your free hand under the bleed valve when you bleed the rad.

You have air in the radiator, it prevents water from filling the whole radiator so it doesn't warm up.
You need may need a key to "bleed" the radiator by opening a valve at the top of the radiator.
Open the valve slowly, you should hear it hiss, then water should come out (have a rag ready)
If you have a combi boiler or pressurised system you may have to replace the air with water to allow all the air to escape.
There will be a filling loop to do this either on the combi boiler or close to the boiler(should be close to a small red expansion tank and pressure gauge)
Open the valves on the filling loop with the bleed valve on the radiator open till water starts to come out. Then close the bleed valve. Open the filling valves again to allow the pressure to rise on the pressure gauge to the pressure indicated on the gauge (1-1.5 bar)

Use a radiator key to bleed the air from the top. Locate the small square nut on the end at the top, lock onto it with the key and hear the air coming out. Don't forget to tighten it up again after though or you'll have water all over the floor.

You need to bleed the air out of it. An air lock is preventing the water from filling up the rad. Go to a DIY and get a rad key. At the side of the rad you will find a valve. Open it and to let the air out. You'll know it's out when the water starts coming out. Place a small dish under this spot to catch the water as you re-tighten the valve.

There is air in your radiator...Simply crack open ( no more than 1/4 turn!) the bleed valve on top of the radiator and bleed out the air. You will get air out and when the water starts to come out, shut off the bleed valve. You may need to do this a few times. If your system is old, be very careful not to force anything...it may break appart. Anymore problems...email me.

I tneeds bled. There is a square screw at the left hand side of radiators at the top. You should have a key to turn it. If not you can buy one at B&Q or somewhere similar. turn the key very slowly, keep a piece of cloth or tissue under the key cause when the air is away fluid will come. You will hear air escaping lock the screw again when the air stops coming and water ery stuff comes instead. Your radiator should heat up properly now.
