Heating large-area halls requires a well-thought-out approach. Steel halls, due to their large spaces, are characterized by high energy requirements, which can only be met by efficient and energy-saving heating systems. In this article, we will focus on heating production halls, presenting the advantages and disadvantages of air curtains, heaters and infrared heating.

What are the best methods of heating large-scale halls?
The choice of the appropriate heating method depends on many factors, the most important of which are:
- size of the hall;
- type of business activity;
- required temperature in a given zone;
- budget .
Depending on the specifics of the facility and its use , we can choose from several popular heating methods that will ensure efficiency and thermal comfort while minimizing operating costs.
Below are the three most popular solutions:
- Air curtains – effectively prevent heat loss when entrances are open, which is particularly important in high-traffic halls. Air curtains create a barrier of warm air , minimizing energy losses;
- Air heaters – heaters enable fast and effective heating of the hall by directly supplying warm air to the interior of the room. The heat is intensively distributed over the entire surface, which allows for effective heating of production halls regardless of the cubic capacity;
- Infrared heating – technology involves the emission of infrared waves, which directly heat objects and people in the room, not the air itself. Heat emitters effectively provide heating for industrial halls , especially where traditional heating methods in production halls may be less effective.
Hall heating using radiation heating
Infrared heating (radiation heating) consists in the emission of infrared rays, which directly heat the usable surfaces in the hall, instead of heating the air. Heat radiators maintain the appropriate temperature in the zones where it is most needed , emitting heat in the form of electromagnetic waves. The absorption of thermal energy by solid objects allows for an immediate feeling of thermal comfort when the heating is on.
Advantages of infrared heating:
- Rapid heating . Radiant heaters are able to quickly raise the room temperature;
- Low energy consumption . Infrared heating is more energy efficient than air heating;
- No noise . Radiant heaters do not generate noise in the facility;
- Possibility of precise control . The heat emitters can be precisely adjusted so that only selected areas are heated;
- Electric power supply . Eliminates gas emissions (exhaust fumes, carbon dioxide).
Disadvantages of infrared heating:
- High purchase cost . Radiant heaters are more expensive than air heaters;
- The need for regular maintenance . Radiant heaters require regular maintenance.

Using air heaters to heat the hall
Air heaters using a heating medium (electric or gas) are used to heat the air. In large halls, where a quick temperature increase is required, air heaters are a practical solution.
They can operate on electricity and gas fuels. An additional advantage of heaters is their mobility – portable devices are available that can be adapted to the specifics of the facility. Properly selected heaters can quickly and effectively provide the appropriate thermal conditions in the hall.
In the case of production halls, where it is important to maintain a stable temperature over large areas, heaters are one of the most efficient solutions that allow for even heating.
Advantages of air heaters:
- Low purchase cost . Air heaters are cheaper than radiant heaters;
- Ease of installation. Air heaters are easy to install;
- Possibility of use in various places. Air heaters are available in various sizes and configurations, which allows them to be used in various places.
Disadvantages of air heaters:
- High energy consumption. Air heaters consume a lot of electricity or gas;
- Noise. Air heaters generate noise;
- Uneven heat distribution. Heat is distributed unevenly, which can lead to temperature differences in different parts of the hall.

Air curtains and efficient use of heat in the hall
Air curtains are devices that create a stream of warm air at doors or gates. Radiators allow you to maintain the temperature in a room without losing heat .
Air curtains are particularly useful in production halls , where access routes, e.g. gates, are often open.
Advantages of air curtains:
- Efficient use of heat flow . Air curtains allow you to maintain room temperature without heat loss;
- Reduction of heating costs . Air curtains allow for reduction of heating costs;
- Improving work comfort . The device allows you to maintain the room temperature at a comfortable level.
Disadvantages of air curtains:
- High purchase cost . Air curtains are more expensive than air heaters;
- Need for maintenance . Air curtains (warm air generators) require regular maintenance.
The use of the presented methods influences the optimization of energy costs and improvement of work comfort in the halls. Infrared heating is the most effective. Air heaters are cheaper, but consume more electricity or gas.
Air curtains are a good solution for maintaining room temperature without heat loss.
In the Onninen wholesale offer you will find a wide selection of useful devices in the heating of a large-scale hall.
