Hi, i'm adding TRVS to my central heating system, but due to the nature of the property, its difficult to tell if the flow and return pipes are the same all around the system, as in i'm nogt sure if some are conected to the lef of the rad and some to the right. Its seems like they are. Now I want to add TRVs to every rad, but does it matter if the TRV is on the flow or the return side?
Also, maybe dumb question, but due to the nature of the layout of pipes, i may end up putting some TRVs on the return and some on the flow side. Will this make a difference to the system and stop it working?
