Efficiency and profitability are key parameters when choosing a heating system. The price of energy resources is quite high, their zealous owners of apartments and private houses are trying reasonably. These two parameters underlie the development of an innovative infrared heating system.
The article we have proposed will help you find out how infrared heating of a private house works. We will tell you how and how you can set up IR heating. You will find out what equipment is needed to achieve the intended goal and how to fix it.
For you, we have collected and systematized all the information about the types of infrared heating systems and the criteria for their selection. For visual perception attached photo selections, informative schemes and video presentations.
The principle of infrared heating
In nature, infrared radiation enters the spectral region of electromagnetic waves emitted by the main "luminary" of our system - the Sun. Thanks to the invisible wave spectrum emitted by it on our planet, all living things are capable of developing.
Scientists infrared radiation, which is referred to as "thermal", is divided into three components, highlighting the near, middle and far spectrum.
The most effective for heating and the safest for living organisms are electromagnetic waves immediately following the visible red side of the middle spectrum.
Almost 50% of the solar spectrum is occupied by infrared rays - the closest to human body radiation
The range of wavelengths of radiation, called "rays of life", ranges from 8 to 14 microns. In a number of sources, the “life-giving” interval is slightly increased: from 6 to 20 microns. However, even these discrepancies in the testimony are not critical.
It is the long-wave spectrum, which is close in value to the radiation of the human body, is involved in the development of equipment and the arrangement of the heating system with infrared heaters.
The heating plates used in the arrangement of infrared heating emit heat with an operating range of 5-15 microns
Infrared installations can be considered a kind of mini-sun. The only difference from the natural "luminary" is that they will warm up the space constantly, regardless of weather conditions outside the room. Such installations work in everyday life from a 220V network.
Infrared rays passing through air barriers heat the solid surfaces of objects located in the room, and they subsequently redirect heat to space
The heater, which is the main component of the device, propagates light waves. Thanks to the reflector, during the operation of the equipment, the object to which the device is directed is warmed up.
The role of “receivers” and then “emitters” of heat can be performed by any objects in the room: ceramic and stone objects, wooden and glass surfaces, living organisms.
Items take heat or transfer it to a nearby space. In the process of equipment operation, the surfaces of interior items in the radiation zone are 7-10 degrees warmer than ambient air.
Infrared heating is perfectly combined with other traditional heating methods, making it easy to organize a "heat island" - a zone of increased comfort in any room with minimal effort.
Both at the household level and on an industrial scale, this type of heating is convenient to use as auxiliary or emergency heating.Heat losses during its use on average do not exceed 10%.

Infrared heating systems suit the ceiling. Cover the film with plasterboard ceilings, decoration panels, rack systems, etc.
Using IR film, a floor heating system is built. Infrared heating works well together with floor ceramics, linoleum, laminate, carpet
IR systems are used in the arrangement of attics, thereby reducing the cost of organizing the insulation of the space limited by the roof slopes
The film version is excellent for heating terraces, loggias, winter gardens, balconies. Objects are heated, not air, so it can be used in open areas
Infrared heating devices include IR devices, which can serve as additional and basic equipment for heating a country house
IR films and heaters raise the temperature from 5º to 20º C in 30 - 50 minutes from the start of work. Heats objects and structures, which then transfer heat to the environment

Advantages and disadvantages of the system
The heating system based on infrared radiation in comparison with convection heating methods has a number of indisputable advantages:
- Wide range of applications. Infrared heating panels are used for heating rooms of all types. With their help, they increase the temperature in warehouses, livestock farms, in utility rooms and in garages.
- High heating rate. The feeling of thermal comfort from the moment you turn on the equipment comes in a matter of minutes. This is due to the fact that air does not absorb thermal radiation, and energy is consumed for its intended purpose with minimal loss. And even after turning off the device for some time, it will continue to radiate heat.
- Silent work. The operation of the heaters is not accompanied by any vibration and noise, and during the heating process no combustion products are emitted.
- Safety for household health. By nature, infrared heat is as close to the sun as possible. It is the most comfortable for humans. The devices used do not emit an unpleasant odor, do not emit toxins and harmful substances, being absolutely safe for human health.
Heaters of this type are not afraid of moisture. Due to this, infrared devices can be safely used for arranging “islets of heat” in the open air, using for heating a garden gazebo and a veranda.
By installing IR heaters, you can significantly reduce heat consumption and minimize the problem of irrational temperature distribution
Unlike spiral heaters, infrared systems do not burn oxygen out of air and do not dry it. The distribution of heat in the room is carried out evenly without accumulation in the upper half, closer to the ceiling of the room.
And in the process of heating, convection air flows that are capable of raising dust are not involved. Thanks to this, it is possible to maintain a constant microclimate, providing conditions for a comfortable stay of households.
Heaters are placed in the floor, ceiling or simply attached to existing ceilings. They are often used in the arrangement of the "smart home" system.
Infrared panels and film coatings are known for their compactness, occupying a minimum of usable area in the room and giving off maximum heat
An argument in favor of the modern system is the fact that in recent years infrared saunas are gaining more and more popularity among connoisseurs of spa treatments.
According to research by Japanese scientists, they are an excellent prevention of many diseases. Penetrating under human skin, the rays warm the blood vessels, thereby contributing to the rapid spread of heat throughout the body.
But the infrared heating system is not without drawbacks. These include:
- Infrared rays have a point effect. Therefore, within one spacious room in one place it may be too warm, in another, on the contrary - it is cool.
- Since infrared rays do not heat up air, but objects, during the heating of the room, the interior of which is made up of objects of technology, a subtle smell of plastic may appear.
- In an aesthetic sense, such pendant heaters are far from always able to successfully fit into the overall interior design.
A fairly energy-efficient infrared heating can not be fully considered cost-effective. Firstly, the equipment itself will initially have to invest a significant amount.
Secondly, in order to achieve rational energy consumption with its help, you will have to spend money on meeting a number of key requirements. For example: building insulation, arrangement of heat-reflecting reflective screens.
Such devices consume, depending on power, from about 50 to 200 W per square meter in one hour of operation
But subject to all the necessary installation conditions, the efficiency of the system can reach the mark of 95%. And to maintain a comfortable microclimate it is enough that the film coating occupies 50% of the surface of walls or floors.
Varieties of infrared heaters
The modern industry for the infrared heating system produces two types of heaters: the film version and the panel version.
The principle of operation for both types of devices is identical: the basis is the emitter and reflector, which focuses the infrared rays in the desired direction
The differences between film and panel emitters are only in design features. When arranging infrared ceiling heating, both film emitters and panels are used.
But for heating the floor, only film-type equipment is used.
No. 1 - panel heaters
Flat heating panels are good in that they allow you to save the living space with a constant height of the room. This is very convenient when arranging rooms with low walls and sloping ceilings.
When IR panels are working, only 10% of the energy is spent on heating the air, most of the heat 90% is directed to objects
Structurally, such devices include the following main elements:
- TEN - a heating element;
- panelreceiving heat from the heater and transmitting energy to heated objects;
- insulationlocated on the back side, preventing the loss of thermal energy;
- plate - reflecting electromagnetic waves from the back of the device;
- cable entry housing, terminal block, etc.
The material for the manufacture of the heater can be ceramic, quartz or tungsten. The material used largely determines the power and efficiency of the equipment as a whole. On top of the heater is covered with a decorative coating, which serves as the emitter of infrared waves.
Depending on the installation method, the panels are built-in and mounted.The first are plasterboard structures with thermal insulation applied to them and built-in graphite thread.
The body of the hinged panels is made of heat-resistant plastic or glass, and the heating element is covered with a screen made of ceramic or anodized aluminum.
Infrared panels are installed under the window instead of the usual battery, or simply hung on the wall or ceiling using brackets
Such heaters for sale are presented in the form of traditional panels and more refined models, decorated in stone or natural wood. Exquisite designer products are able to make a worthy addition to the interior.
No. 2 - film type emitters
Film heaters are most often used if necessary to organize zone heating. For example, when arranging a loggia, arranging a working area or creating a corner for relaxing on the veranda.
Coatings of this type can be placed both on the floor and on the ceiling with walls. The only exceptions are stretch ceilings made of fabric or PVC cloths. For suspended ceilings, manufacturers offer cassette-type infrared emitters.
Such heating systems are film mats in which heating elements are connected in series
The main material of the system is a thin layer of graphite deposited on a thin thermoplastic film or carbon fibers laid in parallel, which produce heat flow when heated.
Film coatings consist of interchangeable modules, so if it is incapacitated to separate a section, it will not be difficult to replace it with a new one, without violating the integrity of the system.
To give film heating systems a more presentable appearance, some craftsmen equip them with decor. For this, a gypsum board frame is first built over the coating, on top of which a decorative finish is applied. The only condition is that it does not contain metal.
More and more fans among connoisseurs of quality and beauty find film heaters-paintings that successfully combine functionality and aesthetics
In advanced versions, IR film heating systems are mounted under a decorative layer. Decoratively designed film heaters are among the low-power devices and therefore are mainly used for local heating of one of the sections of the room.
Classification by the way elements are arranged
Infrared heating devices are on the market in a wide range. By the method of arrangement of heating elements, they can be divided into three groups: floor, wall and ceiling.
Option # 1 - floor heaters
Floor coverings are modular materials, inside which are laid flat heating elements. The coating is available in the form of rolls. For installation, it is cut into pieces of the required size.
Strips of rolled material are placed on the floor so that the emitters are not under heavy furniture; this will prevent a decrease in heat transfer and drying out of the wooden elements of the headset
Insulating material and infrared film are laid directly on the prepared base floor. In the process of laying, the overlapping of the panels is avoided and they try to maintain a distance to the walls of 10-15 cm.
On top of floor infrared strips you can stack:
- carpet;
- parquet board;
- linoleum;
- laminate;
- ceramic tile.
The most successful combination is obtained when ceramic tiles are used as flooring. Laminate is slightly inferior in this regard. And the greatest shielding of infrared radiation creates carpet and linoleum.
Film systems are installed not only on floors, but also on ceilings under hinged structures and slopes of the attic roof. Installation and connection is carried out according to a similar scheme:

Option # 2 - wall and ceiling fixtures
In comparison with floor heating systems, the choice of ceiling and wall devices is wider. In addition to traditional panels, there are also designer recessed models of ceiling emitters.
They can be mounted in suspended ceilings. On sale, they are presented in different sizes and colors.
Plates are placed in such a way that the rays emanating from them are sent to the furniture, and that, having absorbed heat, began to act as a source of thermal energy
Ceiling models of infrared emitters are located at a height of 3 meters and above. With this arrangement, the heat ceiling goes down and diverges slightly to the sides.
Rushing down, the rays first heat up the floor covering. Due to this, the temperature at the level of the legs is always a couple of degrees higher than in the region of the head. To prevent heat from seeping into the street, panels are not placed opposite doors and window openings.
Wall-mounted infrared emitters are placed so that they are above or below the level of the human head
Among wall radiators, it is worth highlighting skirting systems. They are narrow long structures. Systems are installed around the perimeter of the room, placing instead of the usual plastic or wooden skirting boards.
When choosing a place to place the panels, one should avoid recreation areas where there is a high probability of direct impact on households. For example: at the level of a sofa or bed.
Otherwise, the rays directed at right angles will overheat and dry the skin, causing discomfort for residents and guests of the house. The coverage area of directional emitters is one of the main characteristics and is usually indicated in the passport to the product.
Wall IR heaters are used infrequently. The circulation of body and cold air occurs from the bottom up, therefore it is more reasonable to prefer ceiling or floor options
IR heater manufacturers
The production of infrared equipment is engaged in many companies around the world. Among foreign manufacturers, the most popular are:
- STIEBEL ELTRON - A German company that produces products of traditionally high quality;
- FENIX TRADING - a Czech company pays close attention to the issue of energy efficiency of products being created;
- "AIR COMFORT" - The Italian concern relies on creating a safe heating system of a new generation;
- "FRICO" - The Swedish manufacturer guarantees Scandinavian quality and places high demands on the design of products.
Domestic manufacturers are represented by such brands as Bilyuks, "Peony", EcoLine, Almak. In terms of quality characteristics, the products of these brands are not much inferior to imported counterparts.
The cost of domestic-made IR equipment is 30% lower than imported analogues, so a wide range of customers can afford to install it
But it is worth noting that not all of them domestic appliances for infrared heating are supplied complete with brackets. In addition, judging by the reviews, the work of domestic devices is often accompanied by a slight crackle, which can be annoying especially at night.
Caution should also apply to products made in China. Some companies put a “CE"Denoting"China export". Visually, this abbreviation is similar to a sign of compliance with European requirements "CE"Denoting"Conformite Europeenne».
The only difference is that in the second case, the font density is slightly wider and the letters are located a little further from each other. Therefore, in addition to studying labeling, require certificates of conformity.
Competent equipment selection criteria
The main thing you should focus on when choosing heating elements is their constructive solution and operational parameters. To calculate the optimal power, use the classic formula, taking as a basis that an average of 1.2 kW is required to heat 10 meters of area.
There are also commercial units for sale that are convenient to use for temporary heating, placing them in the right place and taking them to the site if necessary. They work both from electricity and gas.
Such a portable IR heater is able to effectively heat a zone with a radius of 2.5 meters, filling the spaces of the room with comfort and warmth
If we compare the models of floor and ceiling types, the difference between them will be insignificant, since in any case the floor and the lower part of the walls will be heated first, and warm air will still rise upward. For this reason, look only at how convenient it will be to place the equipment on the ceiling or floor.
Models with a built-in temperature sensor are convenient in operation: when the temperature in the room drops below the set point, the equipment automatically turns on, and when it reaches the set value, it turns off.
Preference should also be given to devices whose design allows you to adjust the slope of the radiation direction.
When choosing a product, pay attention to the presence of a thermostat, with which it is convenient to set a specific mode and thereby save energy consumption
In general, when choosing heating elements, you need to be guided by the parameters of the product, the materials from which the house is built, the presence of another type of heating system, and, of course, your financial capabilities.
But do not be tempted by products with unreasonably low cost. In an effort to reduce the cost of production, some manufacturers do this at the expense of quality, saving on contacts and using low-quality wires.
