Commercial Door Heaters

Commercial door heaters are special heating systems for loading docks, warehouses, car washes, construction sites, and other large commercial and industrial buildings.

door heaterThey are typically used to heat large, high-traffic doors, such as hangar and garage doors, that are frequently opened and closed.

Commercial Door Heaters for Optimal Comfort and Efficiency

Commercial door heaters are crucial for maintaining comfort and efficiency in facilities with high-traffic entryways.

These robust units, built in the USA and backed by industry-leading warranties, combine powerful heating elements with high-velocity axial fans to effectively temper cold air rushing through large bay doors.

Advanced Features

Commercial door heaters offer advanced features that benefit users in various ways:

  1. Versatile mounting options allow installation at any angle between horizontal and vertical
  2. Electronic flame safeguards with LED status indicators ensure safe and reliable operation
  3. Durable 12-gauge hot-rolled steel housing withstands harsh environments

Whether powered by electricity, gas, or propane, these versatile heaters are suitable for various applications, including loading docks and car washes.

Automatic Door Install Configurations

They can be mounted 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.

Door Heater Applications

Door heaters can be used anywhere, from loading docks in industrial factories to commercial buildings.

They are typically used to heat garages, paint booths, workshops, and other areas where large doors are frequently opened and closed.
They are often used in cold climates to keep frost or ice from building up on the outside of doors.

Loading Dock Heater Sizing and Key Features

Sizing a heater for a shipment loading dock requires careful consideration of air infiltration through door gaps.

For instance, a single loading dock door with a 2-inch gap around a 10×10 foot truck can lead to heat loss of approximately 50,600 BTU per hour when maintaining a 40°F indoor temperature on a 0°F day.

This significant energy loss underscores the importance of proper heater sizing and door sealing.

Performance Features

To address these challenges and ensure optimal performance, Door Heaters offer:
  1. High-velocity heated air streams to counter cold air infiltration
  2. Versatile mounting options for precise airflow direction
  3. Built-in thermostats for efficient temperature control
  4. Durable construction to withstand harsh loading dock environments
  5. Safety features, including overheat protection
By incorporating these features, door heaters help maintain comfortable temperatures in loading dock areas while minimizing energy loss, ultimately improving worker comfort and operational efficiency.

Loading Dock Door Heaters

Loading docks on warehouses and factories can use door heaters for a variety of reasons, including:
  1. Heat loss. Open doors let energy escape, driving up costs. Dock heaters prevent precious warm air from exiting through open truck doors.
  2. Inconsistent temperatures. Products and workers suffer when docks cycle between cold and warm. Open doors make stable temps hard to maintain. Commercial heaters curb this fluctuation.
  3. Discomfort. Employees endure frigid blasts of winter air upon each opening. This cripples productivity and morale over time. Targeted dock heating keeps staff warmer.
  4. Product protection. Many items are sensitive to even small dips in temperatures. Brief cold snaps degrade integrity. Commercial heaters safeguard inventory quality.
  5. Inefficient heating. Attempting to warm full warehouses requires excess energy usage. Dock heaters strategically temper zone areas only, supporting sustainability goals.
Commercial gas-fired door heater models are available that are made to be easily moved around and used in warehouses. It also has a good fuel economy and works well for a long time. Models are available with a heating capacity of 900 MBH and an airflow capacity of 7,000 CFM. They burn natural or LP gas and use a single 20-amp 230/115/1/60 circuit. They will quickly warm large areas and maintain space temperatures.

Car Wash Heater System

Door heaters are beneficial for car washes in several aspects, such as:
  1. Door heaters can help warm the wash bay, making the washing process more comfortable for employees and customers during cold weather.
  2. A proper car wash heater system can dry the cars efficiently.
  3. They can lower energy costs by preventing warm air from escaping through open doors and cold air from entering the wash bay.
  4. They can also make the car wash run more smoothly by making it easier to open and close the doors, which reduces the time and effort needed to wash a car.
  5. Door heater parts can also improve customer satisfaction by making the waiting area warmer and more comfortable.
