Heat-demand calculator Calculate your required heat demand for selecting the appropriate heater. Heat demand calculator with suggested values for room temperature, outside temperature, K-value and air exchange. Please note that the calculated heat demand (kW) is only a guideline! Length of the object [m] Width of the object [m] Average height of object [m] Room temperature [°C] Suggested values for room temperature:15°C in halls12°C in case of severe physical activity17°C with predominantly non-seated activity19°C with predominantly sitting activity Outside temperature [°C] Suggested values for outside temperature:-10°C to -12°C in northern Germany-14°C to -16°C in southern Germany K value [W/m2] Suggested values for K value:0,6 for well insulated objects1,0 for normally isolated objects2,0 for poorly isolated objects3,5 for non-isolated objects6,5 for objects made from single foil Air exchange [x times per hour]Optional Suggested values for air exchange:0,5 to 1,0 for closed halls2,0 for halls with increased ventilation through doors and windows3,0 for halls with large gates (car hall, warehouse ...)
