DETERMINING THE REQUIRED HEAT OUTPUT
There is no absolute rule that would allow the calculation of the required heat output. This power is determined by the
space you want to heat, but it also largely depends on the insulation. On average, the required heat output for a properly
insulated room would be 30 kcal h per m
3
(at an outdoor temperature of 0°C).
