I have to fit some new central heating radiators to the homestead. Easy enough job to do, done quite a few in the past.
I was at the local Chapel this morning and noticed that both pipes that fed a radiator on the wall came through holes in the wall one above the other about 6 inches apart. Nothing strange about that. What I am curious to know though is this. One of the pipes went to the bottom right of the radiator and the other one went to the top left with a TRV on. Does having this arrangement rather than both pipes at the bottom of the radiator, one each end, have any practical purpose to it. Your thoughts as always would be much appreciated
