I have an old type 21 (600 mm by 1400 mm) that is against a wall I'd like to put furniture against, so I'd like to move it. There is no room to just move it along the wall so I was thinking of replacing it with two smaller ones on either side of the adjacent corner of the room. I guess the old radiator was probably just under 2 kW and I have room to put one 600 mm by 600 mm and one 600 mm by 700 mm type 22 radiators - I think they would give me sufficient heat output at just over 2 kW. Each would have its own TRV and I'd put them at the sides furthest away from the corner to minimise one radiator affecting the other's TRV. The plumbing looks straight forward - I'm a reasonably competent but occasional DIYer. Does that sound reasonable? Any tips or things I should look out for?
