Re-Radiator valves. Does it matter which end the TVR valve goes ? Or do they have to be the same on all radiators ?

    Many TRVs are bi-flow these days so you can fit them on either the flow or the return. If they are not bi-flow they should be on the flow side.

    It is not so much as which end as which side is the supply and which is the return line. They belong on the inlet side.
