the radiators in my house are cold in oarts of them and i would be grateful if someone could tell me how to get the air out without making a mess? the radiator has a pipe going in on both sides and they are new? there is no unlocking thing at the top like the old radiators to blead them.
There should be a small screw (or bolt) in one of the top corners of the radiator, you need to 'crack' it open half a turn until you hear a pssssssssssssss.
