HEATERS CALCULATOR Calculation of infrared heaters’ power Type of heating: Main Additional Winter Spring / Autumn Windows: Triple glass unit Double glass unit Regular (double) glazing Walls: Good thermal insulation Two bricks or 150 mm of insulation Poor thermal insulation The ratio of the area of windows and floor: 10% 11-19% 20% 21-29% 30% 31-39% 40% 50% Outdoor temperature: Up to -10°C -10°C -15°C -20°C -25°C -30°C -35°C The number of outer walls: One Two Three Four Type of the room above the calculated one: Heated room Warm attic Cold attic Room height: 2.5 meters 3 meters 3,5 meters 4 meters 4,5 meters Room area (Sq. m): Heat loss: kW Infrared heaters kW Power for heat loss compensation for the infrared system: Nb=(0,8)*Qt,where Nb is the heat output (kW), Qt – is the heat loss (kW). Safety factor of 15–20% is given to compensate unplanned heat losses and possible pressure drop during the cold periods of the heating season. Conventional Heaters kW Power for heat loss compensation for convective heating: Nk=(1,2)*Qt,where Nk is the heat output of the convective system (kW), Qt – is the heat loss (kW). Safety factor of 15-20% is given to compensate unplanned heat losses and possible voltage drop during the cold periods of the heating season.
