I have a radiator in the system which is only heating half way all other radiators are working fine. When I bleed the radiator in question I get some air but not enough the top up valve is constantly on and I am still getting no air or water when I oper the air valve on the radiator! Anything else I can do to sort this please help!!!! its driving me mad!! Thanks

Check that the bleed valve hasnt got some gunk in the hole.You might have to take the bleed nipple right out then with a fine pin poke out the hole,get ready to put the nipple back in quickly but if you say its only hot 1/2 way up it will give you time to get it in before you get a flood.
