It was very hard to tell what was the flow in or the flow out side by looking at my radiators. Well, it seems at least on one radiator I fitted the new TRV on the flow-out end rather than the flow-in lock shield end. Is it a big deal or not, generally speaking? Be a pain to have to do the whole thing again. These are upstairs radiators if that's of any help for small rooms. Thanks
