The heating process using infrared radiation occurs due to its physical properties. Mainly such as reflectivity, absorption ability of various surfaces and substances, transmission, dispersion, etc. For example, air consists of nitrogen and oxygen molecules, almost does not absorb, but partially dissipates and easily transmits such radiation. The human body, like any objects in the room, for the most part absorbs electromagnetic waves from this part of the spectrum, only partially reflecting them.
The principle of heating using infrared radiation
In the process of infrared radiation, electromagnetic energy is transformed into heat. Thus, any objects that are in the room, when heated, give this energy to air, as a result of which it is heated.
With infrared heating, conversion flows decrease their speed by an order of magnitude, and the rays, reaching the human body, activate its peripheral circulatory system, which causes thermal comfort 3-4 ° C earlier than with conventional convector heating. Being the most useful part of the solar spectrum, the emitted rays compensate for "solar hunger."
That is, any heated object is a source of infrared radiation. The wavelength of such radiation is determined by the molecular composition and temperature of the object. The energy received depends on this. Another example of such heating is the Sun, heating our Earth. This is the most powerful source of the solar system. The sun is its natural heater. All living on Earth vitally need solar heat, and humanity is no exception. Infrared sun rays travel billions of kilometers in space and at the same time their losses are minimal. Any surface encountered on their way is heated, absorbing the energy of the rays and turning into heat.
The basics of infrared heating
The most comfortable for people are long waves. Since the range of infrared radiation itself is quite large, scientists have divided it into three sub-ranges:
- Short - it is adjacent to the visible part of the world.
- Average.
- A long.
The hottest objects emit shorter waves. The warmer the subject, the shorter the wave.
Heating PLEN is an alternative to the outdoor heating system used by nature. The ceiling mounted PLEN system allows you to get thermal comfort in the same way that it gives it to the whole living sun. The long-wave radiant energy emitted by heating elements heats objects, floors, machines, which, in turn, accumulate it and then give it to the environment. In this case , air humidity remains natural.
That is, the meaning of what has been said boils down to the fact that in order for the room to become warm, it is not necessary to heat the air in it.
What is an ESP and how does it work?
PLEN stands for "film radiant electric heater." This is a infrared heating system consisting of a resistive radiating element located between the polymer films. The basis of the PLEN system is the interaction of infrared radiation with various matter and its physical properties.
A resistive element is called because it consists of several layers of resistor circuits (resistances). When the PLEN heating is connected to the electric network, an electric current begins to pass through the resistors, and they are heated to a sufficiently high temperature - 40-50 ° C. In this case, the material from which the resistors are made is able to emit infrared radiation. And in order for it to heat the room, before laying PLEN, from the side of the ceiling, walls, floor or other surface lay a foil that reflects the directed rays.
Less than 10% of the time it takes to heat the entire room takes up time to heat up the resistor film. Within 1-2 hours, the temperature increases by 10 degrees - this is the minimum interval. Then, the PLEN heating system continues to maintain the set temperature and is switched on periodically for 3-15 minutes for every hour.
Even the best heater will not work properly if it is not controlled correctly. The PLEN heating system, as a rule, consists of a heater and a control unit. The required temperature is set by the temperature controller. The temperature regulator installed in the room itself controls the temperature around it with the help of the built-in temperature sensor and controls a special unit according to the difference between the actual and the set value.
In addition, if the room is properly insulated, then the ESP consumes less electricity.
Application and installation of PLEN
There are no special restrictions on the use of PLEN. It is used both as primary and as additional heating. Installation on a floor, walls, a ceiling is possible. When used as the main heating heating PLEN, user reviews confirm this, it is enough to cover only 75% of the ceiling or floor. Heated apartments, cottages, industrial premises, offices, loggias, etc.
The PLEN shows the highest efficiency in places where there is maximum air exchange.
PLEN for private houses
Infrared heaters are suitable not only for new buildings, but also for reconstruction of existing ones. Choosing heating PLEN, it will be possible to significantly save at the design stage. You do not have to build a special boiler room or allocate one of the rooms of the house for it. Also, you do not have to think over a fuel storage scheme, whether it is coal, firewood or diesel fuel. The house will never have the smell of burnt coal or diesel fuel. In addition, the appearance of the house will not be spoiled by radiators and pipes sticking out of the walls, which are inherent in traditional heating. And most importantly - IR heaters will remove dampness in the shortest possible time, maintaining a comfortable temperature in all individual rooms.
Application in child care facilities
The most acceptable heating system for rooms intended for children is PLEN. Heating of this type is fireproof and convenient. It is not subject to mandatory certification, does not cause dust in the air, convection drafts and creates the effect of a "warm floor", and therefore protects children from hypothermia.
This system is resistant to low temperatures - it even works at -60 ° C. It usually closes about 70-80% of the ceiling.
Installation Requirement
- Mechanical impact on the device is prohibited.
- The building (or premises) must comply with the requirements of SNIPs in terms of thermal insulation.
- Installation must only be carried out by a qualified electrician.
- It is forbidden to lengthen or shorten the PLEN.
- It is forbidden to operate a rolled device.
- It is forbidden to disassemble the film heating of the PLEN.
- The surface must be leveled and cleaned of dust and dirt.
- Contact of PLEN with aggressive chemical media is inadmissible.
- Installation is possible only with a dead network.
- Single-phase input is used only with a total power of up to 5 kW. With more power, three-phase input should be used.

Impact on human health
Studies conducted by scientists have shown that the long-wave infrared radiation has the most beneficial effect on the human body, and in particular, its part adjacent to the middle subband is the "rays of life", the wavelength of which is from 5 to 15 microns. It is precisely in this period that the infrared heating of the PLEN works. In the same range is the thermal radiation of the human body. Back in the sixties, Japanese scientists based on these discoveries patented emitters of a special design, subsequently used in infrared saunas. For decades, scientists have conducted joint research and proved the benefits of procedures obtained in infrared cabins. IR therapy has appeared. Thanks to her, the heating of the PLEN appeared. The reviews of those who used this heating system show that it turned out to be an effective and quite effective way of combating not only colds, but also overweight problems. It also perfectly stimulates the activity of the stomach and helps get rid of cellulite.
Accordingly, any talk about the dangers of infrared radiation for human health is a fantasy, and nothing more.
PLEN - home heating, comparable to heating with light rays. You can achieve uniform, comfortable lighting in the room only by correctly distributing the light sources. The same applies to infrared emitters. When designing an infrared heating system, one should rely on the height of the ceilings, the type of the room itself and its area. Then subsequently you do not have to complain about uneven heating.
