Roxell Siroc Sterling space heater is a appliance with closed combustion, creating vertical air circulation in tall poultry houses (>4.5 meters). Siroc Sterling recuperates the rising warm air, mixes it with outdoor air and releases warm air at floor level. There is a temperature difference between the attic and the floor of just 0.5 degrees Celsius, evenly distributing heat across the entire space.
