Odd Radiator

[R0b1n]

My sincere apologies, if anything like this has been posted already, but I have had a good dig around and can't quite see an answer.

I have a first floor radiator, which I have bled because it is cold at the top. A little air comes out, then nothing. Even opening the valve further makes no difference and the rad stays cold at the top. Pressure is sitting at 1 bar.

Thanks in anticipation.

Does the bottom of the rad get hot when the CH is on?

Yes, it does. Up to about three quarters of the way.

close BOTH valves

open then remove the bleed valve (cloth handy)

poke a pin in the hole the bleed came out of

then reverse the steps

Are you sure valve open both sides.?

wouldn't matter

If you are thinking the bleed hole is blocked, some air does escape when I open the bleed valve, then nothing until I do it again several days later.

Tried Kevplumb's idea, still the same. Anyone else?
