WE have a radiator which has a 'lock' valve on both sides. In other words you have to take off the cover and use a spanner to turn each valve. This radiator has both valves turned off and we now want the radiator to work.

Is there a way to work out which is the "outlet" and the "inlet". Due to the number of pipes going under the floor boards it's difficult to work this out. I assume that one of the valves needs to be fully opened, while the other needs to be opened to "balance" the flow and I am trying to work out which one.

open them both a bit while the heating is on and hold them, the one that gets hot first is the inlet.

Doesn't matter which one is fully open, the flow in/out will be dictated by the one that limits the flow.

As an aside if this is the only radiator that isn't fitted with thermostatic valves then it shouldn't be left fully closed as it may be the "bypass" for pump over-run.
