The process of heating with infrared radiation occurs due to its physical properties. Mainly such as reflectivity, the ability of absorption by various surfaces and substances, transmission, scattering, etc. For example, air consists of nitrogen and oxygen molecules, almost does not absorb, but partially scatters 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.
Infrared heating principle
In the process of infrared radiation, electromagnetic energy is transformed into heat. Thus, any objects in the room, when heated, give this energy to the air, as a result of which it is heated.
With infrared heating, the conversion flows reduce their speed by an order of magnitude, and the rays, falling on the human body, activate its peripheral circulatory system,which causes thermal comfort 3-4 ˚С earlier than with conventional heating by convectors. Being the most useful part of the solar spectrum, the rays emitted compensate for the "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 amount of energy received depends on this. Another example of such heating is the Sun, which heats our Earth. It is the most powerful source in the solar system. The sun is her natural heater. Everything living on Earth needs the warmth of the sun, and humanity is no exception. Infrared rays from the sun travel billions of kilometers in space with minimal loss. Any surface they meet on their way heats up, absorbing the energy of the rays and turning into heat.
Fundamentals 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.
- Medium.
- Long.
The hottest objects emit shorter wavelengths. The warmer the object, the shorter the wave.
PLEN heating is an alternative to the outdoor heating system used by nature. The ceiling-mounted PLEN system allows you to achieve thermal comfort in the same way aswhich the Sun gives it to all living things. Long-wave radiant energy emitted by heating elements heats objects, floors, machines, which, in turn, accumulate it and then release it into the environment. At the same time, the humidity of the air 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 absolutely not necessary to heat the air in it.
What is PLEN and how does it work?
PLEN stands for "film radiant electric heater". This is an infrared heating system consisting of a resistive radiating element located between polymer films. The basis of the PLEN system is the interaction of infrared radiation with various matter and its physical properties.
Resistive element is called because it consists of several layers of resistor circuits (resistances). When PLEN heating is connected to the electrical network, an electric current begins to flow through the resistors, and they heat up to a fairly high temperature - 40-50 ° C. At the same time, the material from which the resistors are made can emit infrared radiation. And in order for it to go to heat the room, before laying the PLEN, foil is placed on the side of the ceiling, walls, floor or other surface, which reflects the directional rays.
The heating time of the resistor film takes less than 10% of the time required to heat up the entire room. 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 turns on periodically for 3-15 minutes during every hour.
Even the best heater can't work properly if it's not properly controlled. The PLEN heating system, as a rule, consists of a heater and a control unit. The required temperature is set by the thermostat. The thermostat installed in the room itself controls the temperature around it with the help of a built-in temperature sensor and controls a special unit, according to the difference between the actual and set values detected by it.
Besides, if the room is properly insulated, the PLEN consumes less electricity.
Use and install PLEN
There are no special restrictions on the use of PLEN. It is used both as a main and as an additional heating. Installation on a floor, walls, a ceiling is possible. When using PLEN heating as the main heating, user reviews confirm this, it is enough to cover only 75% of the ceiling or floor. They heat apartments, cottages, industrial premises, offices, loggias, etc.
PLEN shows the greatest 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 the renovation of existing ones. By choosing PLEN heating, you will be able to save significantly already at the design stage. Don't have to builda special boiler room or allocate one of the premises of the house for it. Also, you do not have to think over the fuel storage scheme, whether it be coal, firewood or diesel fuel. The house will never 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, infrared 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 works well even at -60oC. Usually it closes about 70-80% of the ceiling.
Requirement for PLEN installation
- Do not force the device.
- The building (or room) must comply with the requirements of SNIPs in terms of thermal insulation.
- Installation should only be carried out by a qualified electrician.
- It is forbidden to lengthen or shorten the PLEN.
- Do not use rolled up machine.
- It is forbidden to disassemble the film heating PLEN.
- Surface must be level and free from dust and dirt.
- InvalidPLEN contact with aggressive chemical environments.
- Installation is possible only when the network is de-energized.
- Single-phase input is used only with a total power of up to 5 kW. For higher power, three-phase input should be used.

- Maintenance free.
- Heating costs are 70% lower compared to other heating systems.
- Recoupment of the system in 2 years, including installation costs.

Impact on human he alth
Scientific studies have shown that long-wave infrared radiation has the most beneficial effect on the human body, and in particular, its part adjacent to the middle subrange is the “rays of life”, the wavelength of which is from 5 to 15 microns. It is in this interval that PLEN infrared heating 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. Infrared therapy appeared. Thanks to her, PLEN heating appeared. Feedback from those who have used this heating system shows that it has proven to be an effective and quite effective way to deal not only with colds, but also with excess weight problems. It also perfectly stimulates the activity of the stomach and helps to get rid of cellulite.
Accordingly, any talk about the dangers of infrared radiation for human he alth is a fantasy, and nothing more.
PLEN - home heating, comparable to heating with light rays. It is possible to achieve uniform comfortable lighting in the room only by correctly distributing light sources. The same applies to infrared emitters. When designing an infrared heating system, you should rely on the height of the ceilings,type of the room itself and its area. Then later you will not have to complain about uneven heating.
