Where f1 - the area of one section, (m 2 ); a radiator accepted to installation indoors; b4 - the correction factor considering a way of installation of a radiator indoors; b3 - the correction factor considering number of sections in one radiator also is calculated under the formula:

b3=0,97 + 0,06/Fp;

Where Fp - the settlement area of the heating device, m 2 .
