How do we calculate?
The room's heat demand is estimated from the area, climate zone and insulation. The radiator catalogue output is given for 75/65/20 °C according to EN 442; at other water temperatures the output is corrected with Q = Qn × (ΔT ÷ ΔTn)^1.3 (ΔT = logarithmic mean temperature difference). Required length = demand ÷ corrected output per metre.
