4 Factors to Consider When Choosing an Air Heater

Heat Output

Heat output is critical when choosing an industrial air heater because it determines the heater’s ability to meet desired temperature requirements. Insufficient heat output can lead to inadequate heating and process inefficiencies, while excessive output can result in energy waste, equipment strain, and potential safety hazards. Selecting the appropriate heat output ensures optimal performance, energy efficiency, and safety for industrial processes.


Airflow is vital when choosing an industrial air heater because it impacts how effectively the heated air is distributed throughout the target area or process. Proper airflow ensures uniform temperature distribution, preventing hot or cold spots that could impact product quality or process efficiency. By considering airflow, you can optimize heat transfer, maintain consistent conditions, and enhance the overall performance and reliability of the heating system.

Energy Efficiency

Energy efficiency is crucial when selecting an industrial air heater due to its impact on operational costs and environmental sustainability. An energy-efficient air heater consumes less power to produce the required heat output, resulting in lower energy bills and reduced carbon emissions. By prioritizing energy efficiency, industrial facilities can enhance their economic viability, meet environmental goals, and contribute to long-term resource conservation.

Safety Features

Safety features are paramount when choosing an industrial air heater to ensure the well-being of personnel, equipment, and the facility itself. Adequate safety features, like temperature sensors, overheat protection, and fail-safe mechanisms, help prevent accidents, fires, and equipment damage. By prioritizing safety, industrial operations can minimize risks, comply with regulatory standards, and maintain a secure environment for employees and processes.

Air Heaters, Air Blowers, & Hot Air Blowers: What’s the Difference?

Although they share some similarities, air heaters, air blowers, and hot air blowers (also called heat guns) have distinct functions. Here’s a breakdown of their key features.

Air Heater

This component provides substantial heat output for large spaces and industrial processes, ensuring consistent and widespread heating over extended periods. It requires an external air source to provide enough air to generate heat for the task at hand but not so much that overheating occurs. The external air can be sourced from a blower, air station, or even compressed air for smaller air heaters.

Our air heaters are available in sizes XS, S, M, L, and XL and have the following features:

  • Reliable configuration and dimensions
  • Flexibility
  • Modern, functional design
  • Integrated thermocouples
  • External control

Air Blower

An air blower is used to forcefully circulate air for ventilation, cooling, and drying purposes. While an air heater’s main function is heat generation, an air blower’s main function is air movement. The air blower connects to the air heater to provide the air required for an application.

Our medium-pressure and high-pressure air blowers have the following features:

  • Low noise level
  • Maintenance-free
  • Compact design
  • Oil-free 
  • Long service life with low operation costs

Hot Air Blower

A hot air blower—or heat gun—is a handheld or mounted tool consisting of an air heater for heat generation and an air blower for air movement. This self-contained unit blows focused streams of hot air for localized tasks like paint stripping. Because the unit is self-contained, there are limits to how much air and heat it can produce. These units typically have controls for heat and air built into the configuration, but that’s not always the case.

Our Top Tips for Optimal Performance

Thermocouple Placement

Most of our heat tools are available with a built-in thermocouple. Follow these tips when using a heat tool that contains a thermocouple.

  • Place the heater as close as possible to the target without restricting the outlet to prevent reduced airflow and damage to the device
  • Place the tip of the thermocouple at the point where temperature matters most
  • Make sure that the thermocouple won’t exit the heat path, thus preventing damage to the target and the heater itself

Piping Tips

Here are a few tips and tricks for piping.

  • Use the shortest available pipe to prevent sudden pressure drops
  • If the pipe is longer than three meters, place a smooth wall pipe between the blower and heater to minimize any pressure drops
  • Avoid sharp bends and kinks when using hard piping to reduce the risk of pressure drops
  • Don’t let hot air enter the unit’s air inlet
  • Orient the blower outlet toward the heater
  • Ensure that all heater connections are symmetrical when using multiple heaters with one blower
