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 (0β4) 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 - ΞT30, ΞT35, ΞT40, ΞT50, ΞT60 ΞT 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 ΞT35 or ΞT30 to spec radiators for low-temperature systems. Output is rescaled β a 1000W ΞT50-rated radiator delivers ~630W at ΞT35 β so you size to actual delivered heat, not nameplate. Output β’ Watts and BTU/h side-by-side β’ Metric or imperial dimensions β’ Whole-home heat-loss total β’ Share or export room specs as text For plumbers, heating engineers, and heat-pump installers sizing radiator schedules, and homeowners or landlords running their own jobs.
