Room-by-room radiator sizing. Watts and BTU/h output for any room, factoring volume, glazing, external walls, roof and floor exposure, and insulation standard. Calculation Heat output per room with adjustments for: β€’ Room type (8 presets: bedroom, living room, bathroom, kitchen, hallway, office, conservatory, garage) β€’ Internal volume β€’ Window-to-floor ratio β€’ Number of external walls (0–4) β€’ What's above (loft, pitched roof, flat roof, heated space) β€’ What's below (garage, unheated cellar, uninsulated floor, heated floor) β€’ Insulation level: poor (older single-glazed) β†’ average (modern build) β†’ good β†’ excellent (new-build, triple-glazed) β€’ Mean water temperature - Ξ”T30, Ξ”T35, Ξ”T40, Ξ”T50, Ξ”T60 Ξ”T correction uses the standard panel-radiator exponent (n = 1.30) per EN 442 testing convention. A 5% safety margin is applied to avoid undersizing. Heat-pump systems Select Ξ”T35 or Ξ”T30 to spec radiators for low-temperature systems. Output is rescaled β€” a 1000W Ξ”T50-rated radiator delivers ~630W at Ξ”T35 β€” so you size to actual delivered heat, not nameplate.
