Small radiator on the landing doesn't work, has a lock shield both ends, how do I know which end to turn to get things working? Both pipes in are cold, so that doesn't help identifying the feed
Doesn't answer much, but is the radiator where the thermostat is or once was, if yes guess that potentially makes it the last radiator on the system. [And has no open/close value soas not to muck the thermostat up]
