Electric Heating Power Calculator
This technical calculator determines the required electrical power for heating systems based on room characteristics, insulation quality, and climate conditions. The tool calculates optimal heating capacity to maintain comfortable indoor temperatures while considering energy efficiency factors.
P = (A × W × C × H) / 1000
Where:
P = Required heating power (kW)
A = Heating area (m²)
W = Insulation power requirement (W/m²)
C = Climate coefficient (0.8-1.4)
H = Height adjustment factor (height/2.7m)
P = Required heating power (kW)
A = Heating area (m²)
W = Insulation power requirement (W/m²)
C = Climate coefficient (0.8-1.4)
H = Height adjustment factor (height/2.7m)
The calculator accounts for insulation levels ranging from 80 W/m² (excellent) to 150 W/m² (poor), climate zones with coefficients from mild (0.8x) to severe (1.4x), and ceiling heights with proportional power adjustments for rooms higher than standard 2.7m.
Calculation Example: A 100m² room with 2.7m ceiling height, good insulation (100 W/m²), and moderate climate (1.0x) requires: P = (100 × 100 × 1.0 × 1.0) / 1000 = 10.0 kW heating power.
Additional outputs include power with 20% safety margin for peak conditions, estimated monthly consumption based on 70% average load factor, and total room volume calculations. The tool provides formatting options for decimal precision and thousand separators to accommodate different regional preferences.
