Radiators

Allow roughly 390 to 520 BTU per square metre of floor, then check the output printed on the listing. Size towards the higher figure for north-facing rooms, bay windows, solid walls or a lot of glass, and towards the lower figure for a well-insulated modern room. Every product page gives the output in both watts and BTU at Delta T50.

Usually, if the pipe centres match. Measure centre to centre across the two valves on your current radiator and look for the same figure on the listing. Match it and the new radiator drops onto the pipework you already have, with no lifted floorboards. Fitting new valves at the same time adds roughly 90mm to the overall width.

A panel radiator is a flat pressed sheet. A column radiator is built from vertical tubes joined top and bottom, giving far more surface area across the same width. In the DUSC Columns range a 2 column stands 68 to 92mm off the wall, a 3 column 100 to 118mm, a 4 column 140 to 160mm and a 6 column 243mm. More columns means more heat from the same stretch of wall.
