hi all, my central heating was put in after my house was build and due to concrete floors downstairs i have pipe drops to the down stairs rads. i am thinking about replacing these rads with decorative stainless steel rads or similar. as im goin to all this expense i obviously want to eliminate as much unsightly pipework as possible!! is the any reason apart from akward fitting and reaching the trv that i cant turn the rad upsidedown and come straight from the ceiling into the valves???? the rads im lookin at are very tall and narrow and are only a foot or so from the ceiling. any help would be much appreciated
