We live in an 1800s building with single glazing (which is currently drafty and we are already looking into getting these serviced), and as always the radiators are below the windows.
I've heard lots of people say to tuck the curtains behind the radiators, but a lot of people say to not do this. I think a lot of this is pure speculation and wanted to know whether it's recommended to heat the room or if it actually slows it down?
