One of my radiators was hot at the bottom but cool at the top, and after advice from family that is it needed bleeding, a bought a key and released the air until water appeared and tightened it back up again. The radiator is now working fine and it is nice and hot, but I have no hot water coming out of my taps...Nightmare!
I'm a complete novice at this sort of stuff, hence my plea for help on here!
Could anyone hazard a guess at the problem?
Any help would be most appreciated.
