What type of heater is typically installed overhead in warehouses and large spaces?

Electric unit heaters are commonly installed overhead in warehouses and large spaces due to their effective heating capabilities and ease of installation. These heaters are typically mounted on walls or ceilings and are designed to distribute warm air throughout the large volume of space below. They work by drawing in cold air, heating it through an electric heating element, and then circulating it back into the environment, which helps to maintain a comfortable temperature in areas that are often difficult to heat efficiently.

Their overhead placement is particularly advantageous in large spaces where floor space is at a premium, as it allows for unobstructed movement of equipment and personnel. Additionally, since electric unit heaters can be equipped with fans to distribute heat more evenly, they enhance comfort across larger areas, making them suitable for use in warehouses, factories, and similar environments.

Other types of heating options, such as baseboard heaters and radiant floor heaters, are generally more suited for residential or smaller scale applications where direct adaptation to floor or wall space is preferred. Portable space heaters, while versatile, lack the capacity needed to effectively heat large areas.
