What is the main function of fixed outdoor de-icing equipment?

Heating air
Melting snow and ice
Cooling surfaces
Heating water

The correct answer is: Melting snow and ice

The main function of fixed outdoor de-icing equipment is to melt snow and ice. This equipment is specifically designed to prevent the accumulation of snow and ice on surfaces such as driveways, sidewalks, and roofs. By providing consistent heat to these surfaces, it allows any snow or ice that forms to melt, keeping areas safe and accessible during winter weather. Heating air, cooling surfaces, and heating water do not accurately describe the primary purpose of de-icing systems. Instead, these systems focus on maintaining surface temperatures that are sufficient to keep snow and ice from bonding to the ground or other surfaces, thus reducing the need for manual removal and enhancing safety during the winter months.
