The main feature of this system is that of exploiting electricity to generate heat, which is radiated from the surface of each panel in a very different way from what happens with traditional radiators. The infrared heating system, directly heats the surfaces of the walls and objects in the room, such as tables and shelves, and it ensures an immediate sensation of warmth even on our skin. This is due to the physical properties of infrared rays, which heat the surfaces of surrounding objects instead of the air around them, causing heat to develop inside them. Precisely for this reason, infrared rays are also known as thermal radiation.
In fact, traditional radiators use the principles of thermal convection to heat the air closest to the radiator. Air circulation does the rest: hot air tends to rise towards the ceiling and a circle of hot air is created, which however is distributed unevenly within the room. The result is slow and poorly distributed heating which, in particular, leaves a rather low temperature near the floor.
What is an infrared radiation?
The infrared is located just below visible light, beyond the “red” of the light spectrum. These wavelengths are longer than the waves in the visible light spectrum. The longest of which is represented by red. The infrared wavelengths are in turn divided into families: those with longer wavelengths belong to the “far infrared” family.
How do infrared waves heat up?
Infrared waves don’t need a means, such as air or water, to “travel”. They move easily both in the air and in space, producing heat only when they hit an object, such as the surface of the earth or the wall of a house. When the radiation emitted by an infrared panel has hit an object (walls, floors, internal objects), the rays generate the movement of the affected molecules, which begin to oscillate. The energy continues to be absorbed by the molecules of that object until the oscillation of the same reaches the frequency of the radiation itself. At this point the radiation is reflected. You will perceive these oscillations as a condition of warmth. The first reaction that occurs when entering a room heated by infrared radiation is comfort: the heat is felt, but the origin isn’ understood.
Many fundamental elements of radiation heating systems are related to their use and are the temperature and wavelength of the radiation emitted. Based on the wavelength emitted, there are 3 different heating systems, with different bands between them.
Infrared heating systems
Infrared heating systems are divided into 3 different types: short, medium and high waves.
They represent an excessive heat source to be applied in situations where “Comfort” is required. If positioned too close, they are the cause of headaches, the sensation of heat in the head and eye problems if they are installed too close to people or if they are exposed to radiation for too long. The penetrating effects of near infrared on the skin are due to its high transmission speeds, which have also given it interesting medical benefits.
The heating elements are made of carbon / ceramic or quartz / tungsten to be able to reach the operating temperature very quickly. Medium wave heat lamps are also used in the livestock sector and for cooking food. The medium wave infrared ceramic emitters have been used for some time in public buildings (restaurants, museums, etc.) and industrial buildings because the typical installation distances necessary in these situations (they are positioned on the ceiling or on the wall in another) make them much more efficient and safer than infrared shortwave ones. They also have a longer duration and emit a much less powerful heat, so as to allow a pose closer to people, without this causing the unpleasant side effects. They therefore find application in local heating, using much less energy
Thanks to their lower temperatures, the applications of this heating range from domestic, to commercial to public exercises, guaranteeing optimal “Comfort” conditions. They are widely used in wellness centers (saunas).
It’s important that in every application (which concerns the domestic, sports, commercial or industrial sector), the correct heating system is adopted. Otherwise, there is a risk of installing the wrong system and consequently dangerous for the health and safety of the environment.
Secondly, as we said before, if you are looking to save money by using infrared lamps, it’s important to choose the correct system and power. A wrong choice easily leads to not having the expected savings.
