This has happend since we decorated and removed some off the wall, without disconnecting, to decorate behind, but not neccessarily to the ones we touched. We have a baxi bolier. I dont think its sludge at the bottom as the system is only about 3 years old. Theyre not even that hot at the top, only warm and on setting 5. Sometimes under the boiler there is a drop of water could this be connected?

Never found any radiators yet with air in the bottom !!!!!!!! mind I bet some of the d....heads that answer these questions have a lot of air in the bottom.
Seems to be circulation problems look to see if the pump is turned up high, try turning all rads off and then put them on one at a time when each rad gets hot turn it off and turn another on if all work individually turn them all on and if the same problem persists change the pump.

You should check the pressure on the boiler and if it's below 1 you should top the boiler up and then start to bleed the radiators, but make sure you check the pressure and make sure that it does not drop below 1. You can top it up to 1.5 and then bleed the radiators, but make sure that the valves are open on the radiators as well. If one of the valves are shut, the radiators will not work, because the feed or return might be shut. Make sure that the pressure on the system stays above 1.

They have air trapped in them and need bleeding.
Take a towel and hold it up to the bleed valve at the top of the radiator, the SLOWLY undo the bleed screw using a radiator key (available from plumb centres). You should hear hissing, which is the air coming out, then spitting as water starts to come out (which is what you use the towel to catch). At this point do up the bleed valve and you will find your radiator will get toastily warm.
Repeat the process for each radiator in turn.

The majority of your replys are correct, they do need bleeding. BUT, start with the radiator FURTHEST away from the boiler, and make sure the heating pump is OFF! You may have to do this several times, but it should work.

you had sludge in the bottom of the radiators,which you drag through the system when you removed the radiators,the only way to get the probelm solved is to powerflush the system by a corgi engineer

could be an air block in the pipe usually all you need to do is bleed the radiators you can get a radiator from any hardware store, if that doesn't work call a plumber

You probably need to bleed them or take the excess air out, it acts like a bubble taking up water space. You can get some kind of contraption that can do it without any mess or spillages.

you don't need a plumber - just pop down the hardware and get a radiator key. open the rad with the key slowly til just a little water drips out.
its just trapped air - a bit like after a particularly bad curry.

still never saw one of these so-called radiator keys...they tell you to get... I have ONLY seen the type you can use a flathead screwdriver to bleed the radiators off with....and i'm 50 and have worked in construction and have had numourous homes

it sounds like you need to bleed the radiators, just remember when doing this make sure you have at least 20psi on boiler when bleeding radiators. this will make it easier and faster to release trapped air from system.
