i replaced 2 small radiators in my kids bedroom . they are not heating up , ive bled them and the water comes through hot but as soon as i close the bled they go back cold, all the other radiators in the house work?????????????help
are the valves either side of the rad open,if one is closed this will stop circulation,also is there a trv on one side ,this could be jammed closed(take head off and the pin should be able to push down and pop back up on its own).if its an old trv then it might not allow reverse circulation.hope this helps.
