Infrared heaters provide heat for materials, objects, or spaces using electromagnetic radiation derived from infrared light, assisted by a reflective shield. Infrared heat waves are defined as long electromagnetic waves which are located near the visible section of the electromagnetic spectrum.
Infrared waves give off a large amount of radiant heat, which can be easily absorbed by a variety of different surfaces. The infrared waves are produced by a heating element, and the heat it generates does not need to rely on transportation by air molecules or any other medium.
Infrared heat can transfer to gases and other materials more easily than the heat waves generated from a typical convection heater, and are of higher efficiency than UV lamps, due to its need for light waves to provide heat. The applications that utilize infrared heat include patio heaters, tube heaters (which contain the heating element in a glass tube), outdoor heaters, door heaters, radiant gas heaters (which derive heat from gas flames), radiant heaters, and small space heaters. Infrared heaters can be used to heat spaces ranging from small sheds and garages to large, spacious warehouses.
There are some infrared heaters that make use of metal, ceramic, or glass as a heating element, but the most commonly found heating element is quartz, due to its ability to heat more quickly than any other heating element. Another heating element is tungsten, which is often found in electric infrared heaters. Electric infrared heaters are used in applications that require immediate heat, such as household appliances.Read More…
Infrared heating is used for other applications such as relief from arthritis-induced joint pain, animal care in veterinary clinics and zoos, glass processing, drying of coatings, and plastic welding. Infrared heaters are highly energy efficient, and are thus considered more “green,” or environmentally friendly way of generating heat, than other types of heaters. It is more environmentally and economically beneficial to use infrared heaters in the place of forced air heaters, especially in applications such as space heating, curing, and drying.
Every material will react and absorb heat differently. Thus, when determining what the infrared heater will be used for, a material’s ability to absorb radiant heat must be taken into careful consideration. Infrared light differs from other heating methods, as it generates heat immediately instead of there being a delay between the point where a machine is turned on and when the heat’s effects are noticed. Infrared air avoids heating any covering in between it and an object or surface. Therefore, infrared heat saves time and money because of its ability to heat an object or surface in a short amount of time. Buildings such as garages, barns, and sheds have openings that allow large amounts of air to escape. Therefore, infrared heaters are used above the doorways to prevent heat loss by heating incoming air.
Infrared heaters are constructed from a heating element and a reflective surface, which is used to direct heat waves a certain way. The heating element comes in a protective enclosure in order to prevent burning or injury. This enclosure is made of a material that is able to endure high temperatures due to the material being in such close proximity to extreme heat. These materials include steel, stainless steel, iron, copper, brass, or aluminum.
There are multiple considerations that need to be made when it comes to an infrared heater’s design. These considerations include the material choice for the shield, the heater’s maximum internal temperature, the amount of voltage needed to turn into infrared waves, and the maximum wattage the heater can produce. Different heating elements can be found among different types of heaters, such as electric and gas heaters. However, both types can be referred to as tube heaters due to both of their heating elements being encased within a radiating tube. Another type of heater, gas heaters, get their heat energy from a gas flame, and utilize various tubes, filaments, or ceramic heat exchangers in combination with a group of reflectors that direct the heat. There are some types of radiant heaters that feature fans or other devices that redirect heat waves and spread the heat around a particular area. However, this is not a necessary feature.
The use of infrared heaters have other advantages. They do not burn fuels, and thus do not emit fumes that are hazardous to the environment. Additionally, this minimizes any health risks that come with the emission of such fumes. Infrared heaters do not produce high carbon dioxide volumes, and are thus do not remove oxygen or moisture from the surrounding air. Because of this, infrared heaters are safe to use for residential and livestock heating. Another advantage is that there is a reduced burning or fire hazard. Infrared heaters do not need air molecules to transport the heat they generate. As a result, infrared heat can heat an object evenly.
Infrared heaters are recommended over conventional heaters, especially in an industrial setting, as conventional heaters leave pockets of cooler air depending on the space’s convection currents. Due to the fact that conventional heaters require air to transport the heat they generate, they cannot uniformly heat a space as well as an infrared heater can.
Infrared Heaters: How Do They Work?
If we talk about the universe’s infrared heater, the Sun. A large amount of infrared (heat) energy is released from the Sun as a result of the process of the combustion of gases. This energy works as the fuel for the life on the Earth. This energy keeps us warm.
Based on the working principles of the Sun, scientists have blueprinted the Infrared Heater, which is a heating appliance that radiates heat. The heat released by this innovation helps us keep our homes warm during the cold weather. There is also a range of large-size industrial infrared heaters that are used by manufacturing businesses as a source of energy.
How Infrared Heaters Work?
Infrared heaters are available in various designs. Based on their application, we can classify them in three basic categories – home or indoor heaters, outdoor heaters, and industrial infrared heaters. These heaters offer a broad spectrum of benefits that have ignited the adoption of these heaters at industrial and commercial levels. You might not be familiar with the benefits of these essential appliances but ask any industry expert they will explain how important heating applications, specifically infrared heaters, are for them.
As the name goes, infrared heaters emit infrared light that we cannot actually see, but feel. Just like you how can feel the heat produced by the Sun, you cannot see that heat coming to you or around you. To see these rays, you would need special glasses. Infrared light is, in fact, a type of radiation or radiant energy that has a longer wavelength than that of normal light with an extended red edge. This radiant energy is invisible to the human eye.
Infrared heaters make use of this invisible light and energy to warm up an area or application they have been installed in. This energy does not heat up the area or space that is not in its direct contact or exposure. When you are under tree shade or in your room the infrared light of the Sun is blocked and keeps you cool, but as you come out in the light, you feel the warmth. Industrial infrared heaters work on the same principle.
Benefits of Infrared Heaters
If we would compare the efficiency of infrared heaters with that of ordinary gas heaters, we would realize why infrared appliances have a higher adoption rate these days. Infrared heaters work on electricity, because of this, they are more controlled in comparison to gas-based heaters. Additionally, infrared heaters can provide quicker and more resourceful heating to your rooms and applications. They warm your room faster than any other heater can. Further, they are energy efficient, since their heating can be set per the application type and need. Furthermore, these heaters are more eco-friendly than other varieties of industrial heaters. Electric infrared heaters do not release pollution or harmful gases, they do not convert oxygen into carbon dioxide.
