Hi all -- I'm adding a towel radiator in the upstairs bathroom so I've got some floorboards up and I wanted to check that a couple things I noticed are normal.
i) The feed and return pipes come up out of the combi boiler into the bedroom, where there's immediately a radiator with 15mm pipe going into the feed at one side and the return at the other. I guess this is ok but does it mean that hot water is going to be returning to the boiler immediately? Is that an problem?
ii) About halfway along upstairs there's a 15mm pipe that directly connects the feed pipe to the return. It's 2 t-junctions so the pipes also continue on to supply the other upstairs radiators. I guess this is to ensure that the water can flow round the system even if all the radiators are shut off, but might this mean that not enough hot water gets to them?
Maybe these aren't a problem at all -- I'm not a plumber -- but I thought I ought to check while the boards are up and it's all easy to fix.
