Radiant Tube Heater
Radiant heaters are widely available in Iran, with the radiant tube heater being one of the most popular types. These models are produced in U-shaped or linear forms and come in various thermal capacities. The design features a burner at one end of the tube and a fan at the other. Because of their unique radiant tube structure, they are also known by the name Garmatab. The Garmatab brand, recognized as the first and highest-quality manufacturer of radiant heaters in Iran, introduced these devices as radiant tube heaters. This type of heater is particularly well-suited for providing warmth in large spaces with high ceilings and in open environments.
Radiant tube heaters are produced in various models, each designed for different spaces and applications. They are installed horizontally at a height. This model uses radiant heat transfer to warm objects by emitting infrared waves. Once these waves hit objects, they release their thermal energy, helping to warm people, objects, and the surrounding area. Since large halls and hangars often experience significant heat loss through doors and windows, using a radiant tube heater can lead to substantial energy savings.
Radiant Heaters for Outdoor Spaces
Radiant tube heaters can easily provide heating for outdoor spaces. These devices warm the target area by emitting infrared radiant waves, ensuring thermal comfort. Radiant systems are highly effective for heating objects or people within their thermal umbrella.
In Iran, most radiant devices operate using natural city gas at standard household pressure. However, in areas where city gas is unavailable, electric radiant heating options are also accessible. Generally, radiant products are categorized into ceramic, electric, tube, and central radiant types.
How a Radiant Tube Heater Works
A radiant tube heater is made of several key components that ensure its optimal performance, including a special radiant burner, heat-resistant tubes, a reflector, a turbulator, and a suction fan.
When liquid or city gas enters the burner, it mixes with a set amount of oxygen and ignites with the help of high-voltage sparkers. The resulting flame flows through the heat-resistant tubes. The turbulators inside the tubes control the flame’s speed, ensuring its temperature is fully absorbed. This process allows the tubes to reach an average temperature of about 300°C.
This type of heater is one of the safest options for providing warmth in large, open spaces. It’s also very quiet and takes up minimal space.
The radiant tube heater is used to provide heat for a wide variety of spaces. It’s available in different thermal capacities to match the fuel type and specific application. Its many benefits have led to its widespread and growing use.
Advantages of a Radiant Tube Heater
Because of its unique features, a radiant tube heater is one of the best choices for heating large spaces. Here are its key advantages:
- Fast, Uniform, and Localized Heating: This system can distribute heat quickly and uniformly throughout an entire space, while also allowing for localized heating in specific areas.
- Significant Cost and Energy Savings: By optimizing fuel consumption and operating at high efficiency, this heater substantially reduces energy use and long-term maintenance costs.
- Easy Installation and Space-Saving Design: Installation is quick and simple, as this heater doesn’t require complex ductwork or plumbing. Its design also saves physical space, as it’s typically mounted out of the way.
- Improved Air Quality: The system works without circulating air, which helps reduce airborne dust and pollutants, leading to better air quality.
Difference Between a Radiant Tube Heater and an Industrial Heater
Industrial floor heaters and radiant tube heaters provide warmth using different methods and have distinct features.
Industrial Floor Heaters
These heaters use convective heat transfer. In this system, air is heated first, and then the warm air gradually heats objects, people, and the entire environment. A major issue with this method is significant heat loss and the accumulation of heat near the ceiling. Since air is the medium for heat transfer, providing localized heating is difficult, and heat cannot be directed precisely to specific areas.
Radiant Tube Heaters
Radiant tube heaters work differently. By generating radiant heat, they minimize the temperature difference between the floor and the ceiling. This means the temperature near the ceiling and the floor is almost the same. Because these heaters don’t need air movement to transfer heat, the temperature difference between these two areas is very small. This feature allows the radiant tube heater to provide a more uniform distribution of heat than industrial floor heaters, creating a much more comfortable heating experience. This is a crucial point to consider when buying a radiant heater.
