Door Heaters Industry Information

Door Heaters

Door heaters provide a stream of heated air across frequently opened doors and entrances of buildings in order to create a barrier between the air outside and the air inside to avoid heat loss and unnecessary energy expenditure. Commonly used in shops, hotels, entrance halls, and reception areas, and in workshops and warehouses, door heaters prevent exterior cold air from entering a large space every time the door is opened and prevent the loss of heated air in the same way.

How Door Heaters Work

When a door is opened into a sealed building, a vacuum is created that encourages air movement. Installing a door heater disrupts this process and prevents air exchange from inside to outside. Door heaters can be gas-fired using a gas flame to create heat, they can use boilers and steam as a heat source, or use an electric element to create heat. An air propeller, or fan, will be needed to force air across the door opening and create enough resistance to prevent interior-exterior airflow. Therefore, doorway dimensions need to be considered when determining the size and capacity of door heaters to ensure adequate coverage. Larger door openings such as warehouses or garages may require more than one heater, and these can be placed side by side to fully cover the open space. Door heaters are ceiling or wall mounted, but optimal performance and results should be placed as closely as possible to the top of the door.

Design of Door Heaters

Typically, a switch is installed on the doorway or connected to the door's opening mechanism, which turns the door heater on each time the doors are opening and closing, as this is when the barrier is required to prevent heat loss. The continual operating of the door heater would result in high energy expenditure and the potential for overheating within the space itself. Therefore a trigger switch or sensor is a necessary part of the mechanism. In door heaters, there are options for adjustable levels of heat and airflow. Some units can be run without the heating elements on and therefore are able to be further used in the summer months. In warmer weather, the purpose of maintaining the interior temperature of a space to avoid extra energy loss is similar – to prevent the loss of the air temperature within the building (in this case, cooled air) and to prevent the entry of the outside air. Another use for door heaters is for the general heating of space when a high level of space heater is required. Some models of door heaters are adjustable, and the heated airflow can be directed into a room rather than across the opening.
