Hi hope someone can help. I have one radiator that does not heat up beyond half way. I have tied balancing, bleeding and have drained the radiator down. As I did this just at the end came the hissing of air. I then refilled the radiator but have got exactly the same problem. Also, when I open the bleed screw, nothing happens, no air or water comes out. it appears that I have got an air lock in the radiator.
This problem has only occurred since I drained the CH system to do some decorating.
Any thoughts?
thanks
