Sections needed

output 1 543,00 W for 1 500,00 W needed

Actual section ΔT48,00 K

Section power at regime110,00 W(factor 0,61)

Rated watts per section assume ΔT=70 (75/65/20). In a real 55/45 regime actual power drops to ~55% — low-temp systems need roughly double the sections. The 100 W/m² estimate is rough; for corner rooms and old houses use 130–150 W/m² or an exact heat-loss calculation.
