Hi,
The radiator in the master bedroom is often cold while all others are hot. It's the furthest radiator from the boiler upstairs (and the biggest, probably 7ft or so in length). I've tried to bleed it but water there is no air.
The general fix is pretty easy. Turn the lockshield half a turn clockwise (closing it, I believe) and then turn it half a turn anti-clockwise. A few minutes later, the radiator is hot again (top to bottom). I tend to have to do this every 2-3 days and then it may last for a week or two before I need to do this again.
New combi-boiler fitted about 3 years ago with a power flush.
This also happened last winter - can't recall if I had to do it the first year after the new boiler was installed.
Just curious why I have to adjust the lockshield and return it to the normal position every so often and what could be done to fix this permanently?
Cheers,
Clive
