I have an internal, decorated plasterboard wall (aka drywall outside UK) with poor studding: 120cm from its left end, there is a 22mm wide (i.e., as measured horizontally parallel to the wall) stud, then a 38mm stud (the two studs are spaced 60cm), then, after further 78cm, the jack stud of the door. I couldn't find other studs. I need to hang a ~2500 BTUs radiator (I have gas central heating), and I'd prefer to avoid both hanging on plasterboard and adding battens/noggins to fix the brackets.
So I thought to fit a vertical radiator (total width 27cm, empty weight between 10 and 20 kg) by fixing all the four brackets to the 38mm stud via steel plates/flat brackets similar to this one:
More precisely, my idea is to fix to the 38mm stud the steel tee plate using its central holes, and then fix the two rad brackets one using the left holes on the tee, and the other using the right ones, symmetrically. Possibly, vertically aligning more than one tee on that same stud, and thereby avoiding anchoring directly on plasterboard.
Would that work and be doable? Any suggestion welcome.
