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

Most commercial door heaters have a heating element and a fan. These two parts work together to move large amount of warm air toward the door.

The heating element can be powered by electricity, gas, or propane, depending on the specific heater model and the needs of the facility.

Commercial door heaters we provide are built in the USA and are backed by industry leading warranties. They can handle the heavy use and rough conditions such as loading docks and car washes.

They are often equipped with built-in thermostats, which allow the user to set and maintain a desired temperature, and safety features such as overheat protection to ensure safe operation.

They can be mounted to the wall or ceiling and can be direct or indirect-fired, with direct-fired heaters blowing hot air directly onto the door and indirect-fired heaters blowing hot air into the space. 

They are typically installed on the outside of the door, but they can also be placed on the inside.

Car Wash Heater System

Door heaters are beneficial for car washes in several aspects, such as:

  1. Door heaters can help keep the wash bay warm, which can make the washing process more comfortable for employees and customers during cold weather.
  2. Proper car wash heater system can dry the cars efficiently.
  3. They can lower energy costs by keeping warm air from escaping through open doors and keeping cold air from coming into 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 cuts down on the time and effort needed to wash a car.
  5. Door heaters can also improve customer satisfaction by making the waiting area for customers warmer and more comfortable.

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. This drives 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 demands excess energy usage. Dock heaters strategically temper zone areas only. This supports 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.
