Heat guns TVK “Barkhan” (“KUPOL”) for heating and drying large rooms
Fan heaters should never be placed next to upholstered furniture and wooden objects. Due to overheating, the upholstery fabric may ignite and cause a fire.
On the shelves of stores today you can find models of heat-fans of various shapes and colors.

Any modern thermal fan should have reliable protection against overheating.
Fan heater NW-15 (GENERAL) has a power of 1.5 kW
The fan heater PCSH 0320 RC has 2 kW control units located in the upper part of the housing. There is a remote control
TEV‑3 (“ARKTOS”) with a capacity of 3 kW. The device is controlled from its front panel
One portable heat gun, in principle, can heat an apartment up to 300m2 (30 kW models- Not unusual). However, in practice, in everyday life, mainly single-phase devices for 2–8 kW are used. More powerful technique- three-phase; it cannot be connected to the electrical network of the home

Portable electric heater- a very useful thing. ATin a city apartment, many people feel the need for such a device all year round: in a snowy frosty winter- if the power received from the city heating network is clearly not enough; spring, summer and autumn- when it’s cold outside and the heating isn’t working.

The warming “breath” of a modern fan heater in the room is noticeable even at a considerable distance. In our opinion, electric heaters are the most suitable for a modern apartment: fan heaters, oil-filled (oil) and infrared heaters. “Oilers” are especially good for additional heating of rooms (when the house is chilly due to the fact that the batteries are a little warm), as well as for temporary main heating (in case of a sudden shutdown of heating in the event of an accident)- They heat the air very effectively in the volume of the entire room. ATfan heaters and infrared heaters are used for the same purposes, however, their main strong point- zonal heating (for example, raising the temperature at the workplace at the desk in the office). Portable electric convectors, which can sometimes be found in stores selling household appliances, are also quite appropriate in an apartment. But still, they show themselves better in a stationary installation, say, in a country house, where they can be used to organize a system of main or additional heating.
Time to choose
Before you go to the nearest store or to the construction market, you need to understand whether a portable appliance can satisfy your need for heat. Let’s calculate the thermal power that your heater should have. The area of the heated room (rooms), measured in square meters, is multiplied by 100Tue The calculation results will be quite accurate if the ceiling height is 2.7–3m. (So, for a room of 20m2 in a brick or panel house that you are going to heat, a 2 kW appliance will do.)
However, not everything is so clear. If the room has a high ceiling (up to 4.5–5m) and it is quite cold there- in the windows there are gaps as thick as a finger, and besides, they face north,- it is better to purchase a device about 50% more powerful than the calculations showed. On the contrary, if very little heat is required, since the room is well insulated and modern windows with double-glazed windows are installed in it, then you can ignore this rule and purchase equipment with a capacity of 20–30% lower than the calculated one.
Fan heaters VT-1741 with electronic control and ceramic heaters (VITEK) If the thermal power obtained as a result of the calculation exceeds 2.5–3 kW, we strongly recommend that you study the possibilities of electrical wiring in your apartment before buying. ATin old-built houses, it is “weak”, and the plugs are regularly knocked out when an iron or other energy-intensive electrical appliance is turned on. ATIn this case, too powerful a device is contraindicated. You must first resolve the issue of laying the power cable from the shield on the stairwell to the apartment. It is not always possible to do this legally due to the lack of electrical power, especially if the house is located in the historical part of the city or is an architectural monument.
It is better to refrain from buying an electric heater if you cannot ensure its safe operation. As trite as it sounds, it is a vital condition. A moment of carelessness- and the fire will destroy all the property in the house, besides, there will be a real threat to human life.
This oil heater of the 19th series (DELONGHI) is somewhat reminiscent of … a penguin It is hardly worth considering a heater solely as an element of interior decoration- in such a case, it is easy to acquire a completely unnecessary thing. Pragmatic buyers often decide to purchase a heater based on its price, noise level during operation (especially if the device is supposed to be turned on in a bedroom or office), weight (heavy devices are not easy to move, especially for sick and elderly people). Sometimes dimensions become decisive: in small apartments full of furniture for large appliances, there is often no place either during operation or during storage, especially if there is no relatively free storage room or garage. For other customers, the ability to operate the electric heater around the clock is of paramount importance. If any of these indicators are for you- determining, then when choosing equipment, you can use the table given in the article, in which the types of devices are evaluated according to the degree of compliance with the listed criteria using a 4‑point scale: 1- excellent, 2- good, 3- satisfactory, 4- undesirable.
Spectacular floor model (UFESA), equipped with a spiral heater So, you have chosen the type of equipment, now you can consider the specific models of equipment available for sale in your city. To do this, you should look into large super- and hypermarkets. European-made heaters are almost always available in hardware stores. BUTHere, imported electric heaters in the most complete assortment are usually presented in branded stores of wholesale and retail companies selling climate equipment. If you are at odds with a computer, it is possible to buy a heater through the World Wide Web- in the online store. Such a purchase can be very profitable from a financial point of view, however, you have the right to be biased towards checking the quality of the goods that the courier will bring to your home or office. ATIn any case, upon purchase, the device must be tested in all modes, make sure that the warranty card is correctly filled out. It would be useful to ask the seller where the nearest service center is located,- after all, heating equipment sometimes fails. It is convenient when a repair shop is nearby, or at least in your city.
Next, we will talk in more detail about the design and operational features of the models of fan heaters, oil heaters and infrared heaters on the market.

In summer, a fan heater with the heater turned off is often used as a regular fan.
Desktop household fan heaters can be placed both on the table and on the floor. These models- the most popular and sold. Devices are presented in stores in the widest range. According to the internal structure, they are very similar to each other and differ primarily in their appearance. their bodies are made in the form of high (up to 30cm) or, conversely, flattened (no more than 10cm) a box, an elongated cylinder, a bizarrely deformed sphere, andt.etc. If you want the fan heater to serve as one of the noticeable elements of the interior, then it is logical to choose a model in a plastic case. They usually have the most intricate design, finish color- white, black or metallic. BUTif first- practicality and reliability, it is better to buy a device in a case made of steel sheet.
The “range” of the jet of warm air for desktop models with an axial impeller is usually minimal (no more than 1–1.5m). Through these devices, heated air enters from the rear, and exits, already heated, from the front. BUTHere, in more noisy models of desktop fan heaters with a centrifugal impeller, air from the room enters through the upper or lower grille, and exits only through the front one. The “range” of the jet in this case reaches 2–3m. To change the direction of airflow of a desktop fan heater without touching the device once again, you can purchase a model with an automatic swivel stand, which provides a housing rotation sector of up to 180
Desktop fan heaters are supplied to our country by BALLU (Taiwan), GENERAL (Netherlands), DELONGHI, OMAS (Italy), POLARIS (Great Britain), EWT (Germany), SATURN (Czech Republic), VITEK (Austria), VEAB (Sweden), ” ELARA” (Europe). Models with spiral heaters- the most democratic in price: they cost 280‑1000rub. Ceramic “tabletops” are more expensive- 500‑1800rub.
Floor standing household fan heaters deserve the attention of buyers, despite the fact that they have not yet received a sufficiently wide distribution. These models warm up the whole room well, including its lower zone. Often they become an interior decoration. For example, floor models PCSH 0320 RC and PCSH 0420 RCD (POLARIS) cost 1.8–20 $. Outwardly, they very much resemble a column with a height of about 70cm and a diameter of approximately 15cm mounted on an automatic swivel stand (swivel sector- 60
Portable heat gun (“URAL-MIKMA-TERM”) in a durable, lightweight and compact case ANDfinally, heat guns. The use of these powerful fan heaters in everyday life is limited. ATcity apartment, this equipment is appropriate to use during repairs- for accelerated drying of painted walls, final drying of plaster andt.It can also be used to create an outdoor thermal comfort zone.
Of the domestic manufacturers of such equipment, it should be noted the companies “TROPIK”, “ELARA”, “ECONICA-TECHNO”, “NOVEL”, “ARKTOS”, “INNOVENT”, “FAVORIT”, “ELECTROPECH”. Foreign firms producing guns,- this is primarily FRICO, SYSTEMAIR, VEAB (Sweden). The cost of domestic portable models is 380‑1300rub. for 1 kW of power; imported ones are more expensive- 765‑2700rub./kW.
It should be noted that the cost of an electric fan heater largely depends on the degree of perfection of its control and protection system. Athousehold fan heaters and heat guns automation can be electromechanical or electronic. All the elements of regulation and protection included in its composition are built directly into the body of the device.
Atsimple models of desktop fan heaters- electromechanical: a power switch is installed on the case, sometimes with a light bulb- an on indicator, as well as a step heater power regulator and (or) a bimetallic thermostat. The power regulator allows you to select the heating power (that is, in fact, the speed of heating the room). ATOn desktop fan heaters, the control often also has a “0” position (cool air mode) when the heater is off and the fan assembly is running. Such models are used in the summer- as an “electric fan”. Heating can be limited at a level from 0 to 35–40 ° C, but the user of the fan heater with electromechanical control determines the temperature value “by feeling”, in accordance with his subjective perception of comfort (there is no temperature scale on the regulator knob).

An oil-filled radiator gradually fills the room with gentle warmth. ATan armchair next to it is pleasant to take a break from business: read a newspaper or drink tea. Floor-standing oil radiators have a capacity of 0.9–2.5 (less often- up to 3) kW. They are used most often for additional heating of air in the volume of the entire room. With reliable wiring, they can also temporarily take over the function of the main heating of rooms (for example, in the country). “Oilers” in EU- perhaps one of the most common types of portable heating devices; people have been using them for decades. ToThe advantages of high-quality heaters include a low heating temperature of the body (about 50–65
Outwardly, the simplest oil cooler is very similar to a steam heating battery (however, models released in recent years are losing this similarity more and more). In fact, his body- this is a sealed container, in the lower part of which a heating element is installed, which heats the oil in it. The metal case of the device heats up from the oil. Well, the air in the room, in turn, heats up, passing near the warm ribs of the oil cooler housing, and also as a result of contact with the surfaces of furniture and walls (they “absorb” the heat coming from the surface of the radiator in the form of thermal radiation).
Metal Shrouded Radiator (UFESA) The main disadvantage of most oil coolers- their inertia. The average device warms up to an operating temperature of about 20–30min. However, many manufacturers are taking significant steps to increase the intensity of heating. To speed up the spread of warm air, a special casing was mounted on the radiator fins.- not closed from below and with holes in the upper part. The channels formed between the surface of the casing and the ribs of the sections create a draft that speeds up the circulation of cold and warm air flows (“chimney effect”). Due to this, heat transfer increases: the speed of distribution of warm air is almost doubled compared to normal. Some models are equipped with fan heaters, which immediately begin to supply warm air, while heating elements heat up the oil. ATAs a result, these devices heat the room much faster than conventional “oilers”. AToil radiators of the Rapido series (DELONGHI) use two heating elements: one, as usual, is immersed in oil, and the other is located in the lower part of the body, under the casing. While the first heating element heats up the oil, the second one starts heating the air. To activate the fast heating mode, just press a special button.
Another imperfection of oil coolers- a large mass. A device with a power of 2.5 kW may well “pull” 12–13kg.In order to somehow alleviate the fate of the user, the devices are mounted on small wheels and equipped with a handle, with which it is easy to move them from one room to another.
Atoil coolers have two or three power modes (the mode switch is usually placed on the instrument panel). This is convenient if the device is supposed to be used in rooms of different sizes. Oil coolers maintain the set temperature with an accuracy of 1–2
In order not to trip over the heater in the bedroom at night, the power mode switch on its body is backlit. There are few models with remote control; Of these, Dragon 3 (DELONGHI) should be noted.
An oil radiator with a built-in fan heater quickly heats up the room immediately after turning on the device. Among the manufacturers of oil heaters, we highlight ATMOR (Israel), POLARIS, DELONGHI. Of interest are the products of UFESA (Spain), THOMAS, ROWENTA (Germany), BINATONE (Canada), BALLU, VITEK, GENERAL, EWT. Undoubtedly, the equipment of SCARLETT (Great Britain), WHIRLPOOL (USA), OMAS (Italy), FIRST (Austria), TESY (Bulgaria), VIGOR, BORK (Germany), “AVEST” (Europe) companies deserves attention. A device without bells and whistles, with the most primitive control system can be purchased for 1290–1850rub. Oil coolers with a special casing, such as the Dragon (DELONGHI) models, are more expensive- 2.3–3.70 $. The presence of a built-in fan heater will increase the cost of an oil heater by approximately 350–700rub. Will affect price and timer- a heater equipped with it will cost 200–850rub. more expensive than the base version.

Portable infrared heaters (also called mycothermal) are economical, safe and durable. Their service life can reach 20years It is typical that when using infrared heaters, the temperature felt by a person is higher than the actual air temperature in the room. This effect is achieved by direct absorption of energy from the device. BUTsince this is so, there is no need to overheat the air.
Infrared heaters- The devices are quite light. They weigh 2.5–4kg.The basis of the design of most models is the emitter- usually a tubular heating element- and a reflector made of polished steel or aluminum, focusing the rays in the desired direction. ATquartz, halogen and carbon lamps are often used as an emitter. The filament in quartz and halogen lamps is made of tungsten, and in a carbon lamp- carbon fiber. The infrared energy of the heated filament heats up the lamp tube, the surface of which, in turn, begins to emit a stream of infrared energy. Halogen lamps produce infrared radiation and light. BUThere are quartz and carbon
This “oiler” is supplemented with a halogen heater, which quickly raises the temperature in the part of the room irradiated by it, even in the absence of lamp heating.- practically only IR radiation.
Model PHSH 0416 RS (POLARIS)- an example of a four-lamp halogen heater with four heating modes and a maximum heat output of 1.6 kW. The case of this device is a flat rectangular panel with a protective grid on the front side. It is mounted on a swivel stand. The body rotation function is provided, which practically does not heat up during operation. There is a timer with an off delay of 7.5h, touch panel and remote control. The model looks very attractive, especially in the dark: the light of four halogen lamps resembles the reflections of a fire in a fireplace. The cost of this device is 1.5–1.70 $. Other companies also supply halogen heaters to Europe. Models 9735N1W (ELTA, Germany), VT-1750 (VITEK), RH06, HH19A, HH10, HH21, HH21R (GENERAL) can be noted.
An example of a quartz heater is the floor model VT-1751 (VITEK). This device resembles a small LCD TV- a rectangular box with rounded corners mounted on a swivel stand. The device has two quartz lamps and two power levels. Its cost- about 900rub.
Carbon Fiber Heater AD-H900R Typical Representatives of Carbon Infrared Heaters- devices manufactured by AIRCOMFORT (Italy). The hermetically sealed tube enclosing the carbon fiber filament is housed in a steel housing in the form of a cone (model AD-H900R) or a cylinder with an open segment (AD-F1200R). Not so long ago, the AD-1500 R model entered the market- also in a cylindrical body, but it already has two carbon lamps. Instrument control is very simple. FROMusing the regulator, depending on external conditions, full or half power is set. The case is able to rotate relative to the stand by 180o, which allows you to heat everyone in the room. You can manipulate the heater both from the touch panel and from the remote control, which operates at a distance of up to 5m from the device. Includes overheating protection and tip-over shutdown. The cost of devices is 3–3.50 $.
In addition to AIRCOMFORT equipment, other carbon heaters should be noted. Noteworthy, for example, is the PKSH 0209 RC (POLARIS) model. The NS-1200G (GENERAL), as well as the permanently installed European-made model, is distinguished by an unusual design.- “Makar TOR” (thermal heater reflex), produced by the company “EKONIKA-TECHNO” (price- 3.90 $).
Portable panel infrared heaters can be wall-mounted Bsale there are also panel infrared heaters with a power of 1- 1.5 kW. Their heating element is a steel plate with a special coating. ATan example is the Classic (EWT) model, which has three modes of operation (230, 500 and 1000W), overheating protection, thermostat and roller bearings. In addition to EWT, infrared heating devices are manufactured by HONEYWELL (USA), THERMOBALT (Finland), DELONGHI andetc. They cost 1.6–2.90 $.
ToThe family of portable infrared heaters includes inexpensive domestic wall-mounted heaters based on a special film that are available on the construction markets. Such devices, alas, are not always durable.
The editors would like to thank the supermarket “WORLD OF IDEAL CLIMATE”, the company POLARIS for their help in organizing the filming.
