I live in a flat and the lounge and kitchen are combined. It is quite a spacious room but the focal point of the lounge area is an ugly radiator which is over two metres long! The room is an odd shape and I can't configure the sofas/tv in such a way as to hide the radiator. I would like to replace it with another that's half the size. Is this doable and, if so, would it be expensive and involve changing pipes etc? I have no clue!
