Door heaters and overhead door heater systems maintain stable temperatures at high-traffic entry points through focused airflow and precise temperature control.
They protect equipment, support worker comfort, and optimize energy usage while meeting safety standards.
Have questions about finding the best door heater for your application?
Door heater units can be mounted as above-door heaters or over-door heaters vertically inside roll-top or straight-lift doors or at an angle facing overhead doors. Connected to a door switch, the heater can automatically turn on and direct warm air toward the floor area near the door opening.
Direct gas-fired commercial door heaters deliver focused heat up to 990,000 BTU with temperatures of 116°F. The units project high-velocity heated air at 6,500-7,900 CFM, creating an effective thermal barrier.
A single 24-inch unit effectively covers a 12×16-foot opening, with multiple units required for larger commercial facilities.
Door size determines the required BTU output and airflow capacity for effective heat control. Commercial facilities must match heater specifications to their door dimensions and daily operation patterns, ensuring consistent door heat distribution while maintaining efficiency.
Our UL and FM-rated units feature integrated energy management systems that automatically optimize thermal output and fuel consumption.
