Hi Guys,
Drained central heating to fix a leak on one of the pipes, refilled as normal, bleeding all rads, BUT!
One radiator will just not get hot! I have bled the radiator, there is water in it, flow and return are cold. The rad in question has a drain valve on it, so to test I drained some water out, got hot water to the valve, thought this has cleared an airlock, but after about 10 mins the pipe went cold again, so obviously water is not flowing through the rad. No air is coming out when I try to bleed it.
Any suggestions?
Cheers
