I have 4 hot radiators but 3 cold radiators, 2 are upstairs and 1 downstairs, 1 is in the same room as the hot water tank, 1 directly below it, and the other in the room next to it.I bled them all and whilst I was bleeding them they each got hot in turn but within a short period of time they all went cold again. The 4 that work ok might all be on the same part of the system as 2 are upstairs almost directly above the 2 working ones downstairs which are back to back either side of a wall.The hot water is definately flowing into the radiators when the bleed valve is open but not when the bleed valve is shut, the outlet valves on all the radiators are all un-done.
