The traditional water heating system has sufficient advantages, but it has a lot of minuses. And one of them is the high cost at the stage of the device and the complexity of installation. Therefore, many people seek the opportunity to warm up a house or apartment without radiator systems. This can be done with the help of autonomous heaters. They have different types and types, can work on electricity (most models) and gas (much less). How to choose a heater for home, apartments, rooms or cottages and talk.
Electrical heaters
The easiest way to warm the room is to use an electrical heater. All of them do not require any special conditions for connecting. They can be put or hang, turn on in the outlet and all - you have a heating.
How to determine the power
In order to heat the room with an area of \u200b\u200bup to 15-20 square meters, a sufficient heater with a power of 2 kW. The time for which the temperature becomes normal, depends on many factors, but it must cope. If the insulation is normal or good, out of windows and doors does not blow, heat will become fast enough. Otherwise, you have to wait, although you can use a more powerful instance of the heating device.
If you need to warm the whole home or apartment, to begin with, you should decide on the dedicated power in power. What power is assigned to the apartment, you can learn in the management company. But, in general, if the year of construction until 2005, 7 kW was allocated, after - 10 kW. Owners of private houses are probably aware of the resources allocated to them - they had to do everything according to the project in which everything is spelled out.
Next, before choosing a heater for the house, it is necessary to determine which total power you need electrical heaters. For rooms with medium thermal insulation for the middle strip of Russia, it is considered 100 W per square meter per square meter. But this is for a standard height - 2.7 - 3 m. Some types of electrical heaters for the same conditions require less power, but approximately, 100 watts per square meter are considered. If the obtained digit "fits" into the power allocated to the house or apartment is excellent. Just keep in mind that you have another mass of other techniques and a certain resource is required for its work. If this is not to consider, it will often be able to work the automatic protection device, reacting to overload.
And one more thing, about which they often forget. When determining the power of heaters for the house, do not forget about the level of "thermal lodge" of the inhabitants of the apartment or at home. For some, the optimal temperature is 20-21 ° C, and someone only at 25 ° C feels fine. If you feel about thermo-loving creatures, add a power supply of 20-25%. It is he who will create comfortable conditions for you.
What electrical heaters are the most economical
Of course, the electric heater for home is easy to install - turned on the outlet and there are no problems. But electric heating is the most expensive, so many try to choose the most economical type.
Choosing a heater for the house, pay attention to the efficiency (efficiency). Equipment of the same type, but different manufacturers, may differ significantly on efficiency. For example, you can put two convectors of different manufacturers of 2 kW per absolutely identical rooms. And it may be that in the same room will be warm, in the other - cold. It's all about the efficiency of electricity transformation to heat. In the case of a "cold" room, a significant part of the energy is lost. Such heating will not be exactly economical.
The efficiency of the device is a very important point: fan heaters can also warm air with different efficiency.
If we talk about energy efficiency, then according to the reviews of owners and experience, it is possible to place electrical heaters for home and apartments in the following order:
- The most economical is considered. These can ceiling heaters with tanks and carbon plates, and can be ceramic heating panels. Compared with traditional, they consume 30% less electricity. Due to what? When used, lower temperatures are needed for comfort. This time. Second - they heat objects, not air. And the third - the output to the operating mode is very fast, so the losses are minimal.
- Relatively some electricity is used. But for economical heating, choose convector heaters for the house with a monolithic heating element and a large number of edges. In addition, the electronic temperature sensor should be. It more accurately removes the testimony, due to which the stable temperature is maintained, an unnecessary electricity overrun is eliminated. If you want to choose a heater for home and do not go broke on heating - necessarily the presence of a thermostat. It will automatically maintain the specified temperature, excluding overrun.
- Plinth electrical heaters / convectors. This is one of the subspecies of the convectors, but due to the non-standard form, they should be allocated in a separate group. They have a very small height and width, but differ significant length. They also installed heating elements with additional ribs and the air is distributed due to convection. But some models do not need to mock at all - put, turned on. Everything. Others are nailed to the walls, then covered with covers.
- . Different from convectors by the presence of a built-in fan. It produces more noise (at the expense of a working fan), more consumes electricity, but at the expense of a more active movement of air, the air warms faster. This type of heaters is recommended as an additional equipment. In this class, more economical models with ceramic heaters, they are better in terms of air purity.
- Thermal curtains. One of the subspecies of fan heaters. The form of the body and the heating element (long and low), as well as the assignment. Installed above the front door to cut off the flow of cold air. More powerful heaters are used to create deposit. Since the heating element is powerful, there may be electricity overrun. Therefore, other less powerful devices use to maintain temperature.
- Heat guns. You can consider them one of the varieties of fan heaters, but they have another building and much more power. Due to high power, quickly copble with the heating of the room, then turn on for a short time - to maintain the specified temperature (or another heat source works).
Thermal guns - interior this design you can not call
- . Most of the electricity for heating the room will require oil radiators. These are the most inertial in its class aggregates. They very slowly heat themselves and only after that they begin to warm the air indoors, and also slowly cool. They have another feature - they do not redistribute heat. Near it can be warm or even hot, and at a meter is already zyabko. You can correct the situation by installing the fan that will blow on the radiator, but it will still increase the cost of room heating.
Let's sum up. If you want to choose heaters for home and do not open on heating, then the most economical electrical heaters - infrared, followed by them - convectors with a monolithic heat exchanger and electronic temperature sensor, then convectors with other heating elements. Average effective - fan heaters, the most non-economic - oil radiators.
Neelectric heaters for home and summer cottages
If power supply is stable in cities, the countryside often remains without light. And the interruptions happen, most often, in the worst weather. It is understandable, firstly, the consumption of electricity in these days increases, secondly, the power lines fail in bad weather. Therefore, they often try to make heated at home non-volatile - to be with warmth all the time. If you do not consider ovens and burzhuyki, there are the following options:
Of all the non-electrical heaters described above, gas convectors are most suitable for the home. They were developed as domestic heating devices and the comfort level is given high. Fuel infrared and thermal guns are more equipment for heating technical or industrial premises. They and the view has a non-fried - as industrial equipment. True, fuel infrared heaters are good for heating open areas, arbors, etc.
What heaters choose to quickly warm up the room
Quite often, electrical heaters are used to quickly warm the air indoors. It can be a bath, cottage. They can stand in them, but while she herself herself and starts to warm the room, it takes a lot of time. In order not to freeze during this period and requires a high-performance heater. With these tasks coped well:
In general, if you need to choose a heater for a home, which will quickly warm up air, the best option is a heat gun. Others are not so effective. In order for the premises to warm up faster, take the aggregates with a large reserve in power. Only in this case it will be possible to expect rapid results.
Heaters do not burn oxygen
For normal well-being, it is very important for the air to which we breathe, had a sufficient level of oxygen. If the house heater uses an open fire, it necessarily burns oxygen. Another question is that not all devices use oxygen from the premises. For example, parapet gas convectors take air from the street through a coaxial chimney. That is, on the quality of air indoors, they almost do not affect. For other models - with an open burner - necessarily the presence of supply ventilation. And if you need no heaters for home without burning oxygen, pay attention to the electrical models.
In the case of electrical heaters, the situation is different. As a rule, the heating elements are not heated to such temperatures in which the oxidation reactions occur very actively and the oxygen level is significantly reduced. But, if not to ventilate the room, the well-being is really worsening. Why is this happening? The fact is that if the heating element is heated to 600 ° C, this is sufficient for the combustion of dust and other organic residues that are present in the air. In the process of combustion, oxygen, of course, is used, but not in such quantities that can significantly affect its content.
In the process of combustion of dust, gases (including inventory) are distinguished, which give the unpleasant air and affect well-being. It is this phenomenon that "burns oxygen", although in fact it is not. Nevertheless, choosing a heater for the house, it is desirable that its heating element is not too hot. The highest threshold is 500 ° C, but better - 350-400 ° C. And more - make high-quality ventilation. This is a guarantee of good well-being with any heaters.
- Ceramic infrared panels.
- Oil radiators.
- Electrical convectors of any type.
The equipment listed above does not heat up to high temperatures. Nevertheless, even with a working oil radiator, which can only be warm up to 60-70 degrees, there may be a sense of "shortage" of air. This feeling disappears after conducting. So ventilation is very important and needed. And in order not to worry about the fact that the heated air leaves the room, make ventilation openings with recovery (heat selection at the outlook air). In this case, it is not cold air into the premises, but already a slightly heated.
How to choose a heater on a balcony or loggia
The selection of the heater for the balcony or loggia depends on the degree of its insulation. If, if there is enough insulation and windshop, you can install a convector. Its power depends on the balcony area, but can be considered as for ordinary rooms: 100 W per square meter per square meter.
Infrared heaters can stand on the glazed balcony. And it will be very good to cope with the task of heating. They simply cost more convectors, but less consumption of electricity. So the option is not bad. If you want to make a balcony inhabited and comfortable even in the cold, consider the installation of heating carbon film. It can be mounted on the walls, floor, ceiling. Only to be effective, it takes a very good insulation and the heat transfer layer over thermal insulation. But it will be very warm.
If there is almost no insulation and there are ordinary frames, but you want to spend some time in relative comfort, you can consider options with thermal guns. They will dispel such a volume with a frost to the positive temperature for days. But this is provided that there are no holes. If the "conditional frames" or there are no them at all, you will have to choose an infrared heater to the balcony. It will warm the air, but you. So choose the heater for the balcony, it is necessary only to clearly imagine what you want to have - an additional warm living space or relative comfort for a while.
Ensuring the comfort of stay in the premises of the house at any time of the year is one of the main worries of the hosts. But efforts on the insulation of walls, on the installation of the corresponding heating system, can be in vain if the heat will freely exit through windows or doors. This is especially true of those buildings in which, for one reason or another, they open very often or even for a long time remain in the open position.
Simple situation: Home Home Own any family business - workshop, store or office space. On the one hand, numerous clients are excellent, but, at the same time, the frequent opening of the door is able to quickly play even well-heard premises, and these are the serious cost of energy resources. Another option is the specificity of the activities of the private workshop equipped in the garage or in a special extension, requires constant or very frequent opening of the gate (). To secure acceptable conditions for efficient productive work in the winter time you have to spend exorbitant forces and means to maintain normal temperature. But there is a way out - both, and in another case the heat curtain should help at the entrance door.
Why do you need a heat curtain
It was easier to understand the purpose of the thermal curtain, it should first be understood as cold air penetrates the house through open doors. This process is caused by several reasons - the temperature difference outside and inside the room caused by this drop different pressure level. And plus a very important reason for this is the movement of air masses along the street - wind, created by the vortex flows from passing transport, etc.
The fragment "A" shows the movement of cold and warmer air streams through the doorway in "calm" conditions. Cold air is always denser, and it simply extrudes the more light warm. At the same time, the cold stream is always located closer to the floor - everything, for sure, was felt on its everyday practice, as "pulls cold" to the bottom from under a loosely covered door.
The wind component (Fragment B ") is added to this well-normal exchange. It is of course, the value is inconstant, depends on the direction and speed of wind, stability or periodic gusts, the size of the doorway and other parameters, but in general, the most often such an application of the air movement vector is still present.
As a result, as a result of the addition of both factors, a picture shown in the fragment "C" - the "channel" of the receipt of cold air increases even more in the area, occupying most of the doorway. In such conditions, if the door has to be kept open or often open, no heating equipment can cope with the heating of the room, which will be "thorough". In addition, constant strong drafts are walking around the rooms, sharply increasing the likelihood of colds, even if people are dressed in season.
And what if to file is quite narrow, but a dense directional air flow. So that its pressure exceeds even theoretically possible values \u200b\u200bof external and internal heads ("D" fragment). If you correctly calculate the parameters of such a stream, it will become a barrier for the sharing shown above, burning air masses outside and indoors. Several twisted their configuration under the influence of pressure on it, the flow still retains the necessary "columns" and is crushed only to achieve the floor surface, divided into two directions. A certain part comes out, but still more significant - returns back to the room (fragment "E").
How can such effect be used?
- The picture "A" - winter time. The air receives the necessary heating, and the resulting veil does not only miss the cold masses inside and do not allow heated to break out, but also returning indoors, "has a profound" system of heating.
- However, to consider the air curtain too "narrowly", only as a peculiar heating device, it would be a big mistake. The picture "b" shows its work in the warm season. The situation changes to the back - the cool inner air does not exit outside (although its density in the case under consideration is higher), and the extended summer heat - can not penetrate the room. Thus, the rooms are supported comfortable for people staying temperature.
- But that's not all. Regardless of the time of year and from the operation mode, such a curtain performs another important function (picture "in"). A lot of dust is always weighted in the street, especially if in the immediate vicinity there is a lively motorway or even the railway line. For the same reason, air can be overwhelmed with exhaust gases. Naturally, when all these "bonuses" get into the premises, the local microclimate will suffer significantly. But the heat curtain will quite cope with such a problem. This also applies to the falling snow, a small drizzling rain, and in the summer - the hordes of small annoying insects.
- And one more application. With the help of such air curtains, it is possible to zonate the premises by the type of microclimate created in them. For example, you can "exhaust" the spacious hall at the entrance (where the elevated air temperature is not particularly needed, and there will be unreasonably much energy to warm this room) from the inner residential or work premises, without even installing additional doors.
So, the creation of an air curtain helps to cope with a lot of problems. And all this can be achieved by installing a special device.
Despite the fact that the air thermal curtain itself is a consumer of electricity, its use gives considerable benefits. So, practice shows that the correctly selected and installed device allows you to save up to 30% on energy resources spent on the heating of premises in winter and their air conditioning in the summer. And if the owner thinks more widely, it will not be able to not notice the fact that the lack of cold drafts will dramatically reduce the costs of medicines for households or to pay for hospital sheets of personnel.
Another important dignity - with such a rich spectrum of possibilities, the device itself practically does not occupy a useful place in the space of the room.
For clarity - a small animated roller on the principle of action of thermal curtains:
Video: How does the heat air curtain work
How does an air curtain
As a rule, the air heat curtain shall prescribe an electrical device collected in the case of a pronounced elongated shape.
In the top of the case there is a grille (pos. 1), through which air is taken from the room.
The bottom is the output sloping window (nozzle) (pos. 2), which can be equipped with moving blinds by type of blinds.
Control elements (pos. 3) can be located on the case itself, in accessible to visual control and manipulating place. The control panel, in addition, can be remote, and placed on the wall of the room in a convenient place.
On the case there may be a terminal block to connect to the power supply network, but on household models, most often there is already a folded cable with a plug for connecting to an outlet (pos. 4).
Many modern models are provided, moreover, also remote control using an infrared console (as well as in the air conditioner split system).
The main task of the thermal curtain is the creation of a powerful air flow. And this means that the injection fan becomes the main unit of the device. Typically, these devices are not an ordinary blade, but turbine type, two varieties - more compact radial (pos. "A") or an elongated tangential species (pos. "B").
Pos. "B" is a heat exchanger, where the flow of air is obtained by the desired heating. The overwhelming majority of the models have an electric heat exchanger, where the air receives heating from spirals or Tan. However, there are stationary models of thermal curtains that are connected to existing water heating circuits.
Many modern thermal curtains have built-in filters that are simply cleaned by air from suspended dust.
Electronic circuits of modern curtains provide multi-level protection against short circuit, breakdown on the body, overheating, have thermostatic control modules for heat exchanger heating and fan speed.
Classification of air thermal curtains
There are several gradations of the classification of thermal curtains.
By location relative to the doorway:
- Classical performance Most thermal air curtains are a device with a horizontal installation above the doorway (gate, window, etc.)
- Sometimes, due to certain reasons for a technological or aesthetic nature, the installation of a heat curtain from above may be impossible or irrational. For such situations, vertical devices are provided that are installed by "columns" with one, or even on both sides of the doorway.
Many models in this regard have increased versatility - their design allows, taking into account the specifics of the room, to install them both in horizontal and vertical position.
By installation type:
Most models have a metal housing, the execution of which implies the installation of the device on the wall. However, if there are any increased demands from the point of view of the room, it is possible to choose a thermal air curtain, which is embedded in the ceiling or into the wall in the height of the opening.
By availability and type of heat exchanger:
All air curtains on this criterion can be divided into three groups:
- Curtains with electric heat exchanger. Usually in classification are marked with serial notation RS., RM or RT..
Advantages are the maximum simplicity of the device and installation of the device, high performance performance, the possibility of smooth adjustment of the heating temperature of the air flow.
As the heating elements on old models, ordinary spirals were used, but now it was almost universally abandoned from such an approach, since open heaters "overtake" oxygen and quickly dried the air indoors. Currently, tubular heaters are applied by all familiar Tannes, or more modern semiconductor RTS (PSITIVE TEMPECTURE COFFICIENT), having the possibility of self-regulation of heating and electricity consumption.
The disadvantages of electrical heat exchangers are significant power consumption (not counting the cost of providing fan operation), and some "inertness" when starting - the heat exchanger requires a certain time to access the operating mode.
- Water heat exchanger thermal curtains (series RW).
In such models, electricity is consumed only for ensuring the fan operation and management groups. This is definitely making water heat curtains much more economical in permanent operation.
In the case (outside or hidden) there are nozzles for connecting the device with an existing loop of the water heating system (the figure shows arrows).
Nozzles for connecting the feed and "reversal" systems of the home heating The disadvantages of such a kind of thermal curtains are obvious - this is a lot of difficulties in the installation process. It is necessary to provide in advance of branches from the general contour, and subject to the preservation of the interior aesthetics, such an operation is quite problematic. The heat exchanger of such a curtain has a small tubular structure (like a radiator in a car), which will quickly rush, if you do not provide a filtering device. In addition, the thermal power consumed of this installation should correspond to the real capabilities of the autonomous heating system so that the curtain connection does not affect the heating level of radiators in other rooms.
- Air curtains not equipped with a heat exchanger (serial designation - RV).
Such devices are used in conditions, the years of additional air heating is not required. They protect well from entering outdoor dust, bubbling, insects, from leakage of air conditioned air outwards. Focus are widely used in industrial practice - for zoning spacious premises, protection against warm air in freezer or storage facilities, etc.
In terms of power (performance) and, accordingly, purpose:
- To the series RS. include mini-curtains with a limited application. Their performance is enough for an effective "wrapping" of only small openings, such as the windows of receiving visitors who go into the cold hall, or client service winds in street kiosks, transport office, etc. Usually they are designed for openings with a height of no more than one and a half meters, a width of up to 800 mm.
Air flow rate and volume of pumping per minute - small. In everyday life, such thermal curtains of practical use do not receive.
- Thermal curtains series RM- It is the largest group of devices that are intended for installation in most existing standard doorways, from about 2.5 to 3.5 meters high. Including, they are suitable for or to move from a cold hallway to the residential sector of the house.
The heat curtain of the middle class - it is quite suitable for the entrance door Such devices are the most "running". These series are most often equipped with convenient remote blocks or remote controls.
- Powerful thermal curtains series RTfind application to protect high openings, from 3.5 to 7 meters. It can be a gate of auto repair shop, warehouse or industrial premises, entrances to large shopping centers or cultural and social destinations.
Very often it is to such a category and powerful settings of the series. RWconnected to central heating systems or hot water supply of public buildings and industrial structures. The cost of water thermal curtains - significantly exceeds the same indicator of electrical models comparable in terms of performance and sizes.
There are also heavy duty heat curtains that are able to create an air barrier in openings and drives high up to 12 meters.

How to choose an optimal thermal veil
The choice of air thermal curtain has its own characteristics with which you certainly need to get acquainted before going to the store.
In addition to the already mentioned selection criteria - at the place of installation (horizontally or vertically) and the principle of operation of the heat exchanger, be paid to the following characteristics:
- Dimensions (more - length) of the device itself, that is, the width of the air curtain created by them.
- Performance, that is, the ability to pump a certain amount of air per unit of time.
- The power of the heat exchanger unit.
- Equipment with useful adjustment options.
- Degree of protection, that is, the level of security of the device.
- For interior design of the room matters the appearance of the heat curtain.
Sizes of thermal curtain
The determining parameter is definitely the length of the device. It should provide the required airflow across the entire width of the doorway, not allowing free lumen for the penetration of cold or dusty masses outside. As a rule, the length of such devices lies within 600 ÷ 2000 mm.
For standard doorways, curtains of about 800 mm are usually acquired. With a competent approach, it should be taken into account that the width of the air flow must be at least equal to the clearance of doors, but even better if it is somewhat more.
There is another nuance. The production technology of air dischargers slightly limits the turbine length (up to 800 mm), since the vibration phenomena, which requires a sufficiently costly "suspension" with the exceeding such dimensions.
The length of the turbine is usually limited to 800 mm Trying to minimize the costs at the release of "long" models, many manufacturers go along the path of simplification: placing an electric drive in the center of the device, and the turbines - on the left and right, achieving the desired length. In such a layout, there may be a serious drawback - in the center of the airflow created may form "failure" or the area of \u200b\u200blow pressure, which are capable of becoming a loophole for air penetration from the outside.
If the width of the doorway is greater than the length of the model you like or at all available on sale, it makes sense to purchase two curtains (and sometimes - more), and install them close one to another.
Performance performance thermal curtain
It is quite clear that the heat curtain should create an air flow, the "density" of which, that is, the internal pressure of the air would exceed the external doorway at any point of the doorway, from the installation site and to the floor (the opposite side of the doors).
The calculations are determined that such required parameters are saved at the speed of the air layer at the meeting point with a barrier at least 2.5 m / s. Naturally, the speed due to air resistance drops as it removes from the device.
The speed and density of the air flow depend on the working diameter of the turbine, the speed of its rotation and, it became, on the overall productivity of the injection unit. For example, the table below shows the dependence of the effective action of the thermal curtain, depending on the diameter of the turbine - in some cases it is possible to navigate to such indicators:
| Distance from the output nozzle of the heat curtain | Air flow rate depending on the fan installed in the thermal veil | ||||
|---|---|---|---|---|---|
| Fan working diameter | |||||
| Ø 100 mm | Ø 110 mm | Ø 120 mm | Ø 130 mm | Ø 180 mm | |

| 7 M. | - | - | - | - | 2 m / s |
| 8 M. | - | - | - | - | 1.0 - 2.0 m / s |
Most often in the technical documentation for the product, the manufacturer directly indicates, under what maximum sizes of the opening developed a specific model. There is also sure to indicate the performance of the system, usually in cubic meters per hour. It is considered optimal for a standard doorway with dimensions of 0.8 ÷ 1.0 × 2.0 ÷ 2.2 m. Pumping 700 ÷ 900 m³ / h is considered. However, if you look at the equipment catalogs, there are often curtains and with much more modest values. The unity of the views of manufacturers in this matter is not.
There are special algorithms for calculating the parameters of thermal curtains, which take into account not only the linear indicators of the installation site, but also the features of the location of the inputs in the building, the average temperature differences for a particular region, the predominant direction of winds, etc. Such calculations are the lot of specialists, and if someone is not enough to select the model of the characteristics declared by the manufacturer, then you can contact the appropriate design organization.
Why is the issue of performance costs so acute? From it directly depends on the efficiency of the air curtain.
- Fragment No. 3 schematically shows the work of a properly selected model of the thermal curtain. The air flow retains its "density" to meet with the obstacle, and then approximately ¾ reflected back to the room.
- Fragment number 2 - installed a heat curtain with excessive performance. The speed at the floor of the floor is too large, and the flow is broken down in such a way that there is a significant part of it outward. Of course, it leads to completely unjustified losses of energy spent.
- And on the fragment number 3 it was shown that it will be if the power of the flow created is not enough. The external pressure of the air masses outweighs, and in the bottom of the doorway, a wide "window" opens for cold street air. The meaning of the installation of such a thermal curtain is generally very dubious - she simply does not play any significant role.
Thermal air curtain power
Oddly enough, but this indicator for the heat curtain is not determining - thereby their fundamental difference from, seemingly related instruments - heat guns or installed at the door and windows of the floor or built into the floor of the heating convectors.
The operation of the air curtain heat exchanger is directed not to maintain the optimal temperature in the room, but only on partial compensation of heat losses through the door. Clear. That part of the heated air when working in the "Winter" mode returns back to the room, but this circulation should only have an auxiliary effect on the heating system operating in the building, but not to replace it.
At high air pump speeds, it gives it too high temperatures - the task is complex and very energy-in-cost. Usually, in most models, the temperature increase is limited at best of the 20 degrees, and on thermostatic elements of controls, the maximum value, as a rule, does not exceed 30 ° C - more from the heat curtain and is not required.
But the total power consumed is worth paying attention. From this indicator, the parameters of the dedicated power line, the automaton in the distribution shield of the house, Uzo, and the like will depend on this.
Management and protection systems
All electrical heat curtains are equipped with two control levels: one is responsible for creating and maintaining the predetermined performance "by air", and the second is for the operation of the heat exchanger node. At the same time, the protection system will never allow the inclusion of the heater with a non-working turbine than the protection of the device from overheating is ensured.
The simplest, inexpensive models have pre-installed levels of performance and heating of the shadows, which cannot be changed (the only exception - can be completely turned off the heating when working in the "summer" mode. However, such a cheapness and simplification of the design is unlikely to be justified for use in a private house - you want everyone It is possible to optimally adjust the microclimate indoors.
More complex models are equipped with a stepped adjustment, for example, have 2 ÷ 3 turbine power levels and as many gradations of heat exchanger heat exchanger.
However, recently, heat curtains with electronic control are becoming the most popular, which opens the owners of smooth accurate adjustments.
The presence of a thermostatic sensor will significantly save on electricity consumption - the automation will turn on or off the Tan block only as needed.
Thermal curtains can be equipped with remote control units, which are located on the wall. Convenient in the operation of the models that have remote remote controls.
Like all modern electrical appliances, the heat curtain should be equipped with several degrees of protection against short circuits, overheating, phase breakdown on the housing, voltage drops, etc.
Designers and designers of manufacturers are trying to perform thermal curtains outwardly so that they do not spoil their premises interior. Some models can even become a kind of decoration of the input group.

Independent installation of thermal air curtains, although not welcomed by manufacturers, but still it is quite possible, especially if we are talking about the most common - completely electrical models. According to the degree of complexity, it is much easier to install a household air conditioner.
Can I install air conditioning yourself?
Installation of the air conditioner usually requires special skills, since when installing a split system, it will be necessary to correctly produce it with a refrigerant. How to produce - in a special publication of our portal.
The main thing is to provide for the supply line of the required power, the necessary safety and protective devices (automatic and Uzo), the dope of connection of the device.
Thermal curtain, as a rule, includes brackets (or mounting panel), fastening elements for suspension over the doorway. All installation will mainly be in carrying out thorough markup, fixing the wall mounting parts on the plane and subsequent suspension of the device itself. It can be sufficiently massive, so it should be reasonable caution, and even better - to enlist the assistant.
After installing the device, if it is equipped with adjustable blinds, they should be placed at an angle of about 30 ° from the vertical in the direction of the entrance. On many models, such a bias of the flow is provided for by the design of the air nozzle.
It is possible that the signal cable laying and fastening on the wall of the remote control unit. All these nuances are always described in detail in the installation manual for a specific model, and with them one should read in advance, while choosing the curtain to really appreciate your capabilities.
Installation of a veil with a water heat exchanger is a much more complex event that often requires special heat-engineering calculations and installing additional collector or pumping equipment. Accept for such classes, not having experience - is not worth it.

Video: Several recommendations for choosing a heat curtain at the entrance door
To create a favorable microclimate in the room, it is necessary to maintain a comfortable temperature and not to allow walking drafts. This is especially true for crowded places where the doors are very often opened. Save the inner heat, get rid of drafts and eliminate the likelihood of cold polluted air inwards, the heat curtain on the entrance door will help.
In the winter period of the year, dense cold air, which is hardened by the floor, is rapidly sent to the room through and squeezes warm light air. If you add a wind component to such a conventional air exchange, then strong drafts will be enveloped. In this case, when the door often opens or constantly keeps open, no heating device can cope with the heating of the room. Here it is necessary to create a powerful stream of warm dense air, the pressure of which would be hampered by a pressure of cold air masses, which comes from the street.
With the task, the heat curtain is perfectly coped. It is a kind of cold air cutter at the entrance doors. The principle of its operation is similar to the operation of the heat fan. It is able to reliably protect the room from penetration of drafts and cold from the street, and its inhabitants are from diseases.
In the case of the correct calculation of all parameters of the heat flux, it will not only prevent the penetration of cold masses and will not allow to break out the outward heated, but also helps the heating system, due to the fact that most of it is returned to the room.
The air curtain can be used not only in the winter year. Her work is also justified in the summer season. The directional air mass prevents the cool inner air to go out into the street, and the preheated summer heat is outdoor - to penetrate the room.
Regardless of the season, the curtain performs another important function. It protects the inner microclimate of the room from penetration along with the street air of various suspenders of the suspension. The veil is capable of holding the rain, snow, dust and the horde of small insects.
Helpful advice! The air curtain allows you to zonite the premises, creating a different microclimate.
Correctly selected equipment can save about 30% of electricity, which is spent on heating and air conditioning. In addition, the device itself does not take a lot of useful space and does not clutch the interior of the room.
Heat curtain at the entrance door: design and principle of operation
In appearance, the heat curtain resembles an internal air conditioner unit with a pronounced elongated body. Fence air from the room is carried out through the grille located in its top. The bottom of the case is nozzle, through which the air flow comes under pressure. The control buttons can be located on the body itself or be mounted in a remote block, which should be located near the device. Some models of the curtain have an infrared remote control.
Inside the case there is a heat exchanger, due to which the air is heated, and the turbine injection fan that exercises under pressure outside. As a heat exchanger, a TEN, a spiral or a water heating circuit, which is characteristic of stationary models can be.
Many thermal curtains have a built-in filter designed to clean the air mass from pollution. Almost all models independently of the manufacturer have built-in overheating protection, breakdowns on the body and short circuit. Also can also be equipped with thermostatic control of the fan rotation speed and heat exchanger heating level.
Varieties of air-thermal curtains
There are many varieties of thermal curtains, which can be found on specialized sites. All of them differ in the installation method and the principle of operation.
Depending on the installation option, the veil can be:
- horizontal;
- vertical;
- universal.
The horizontal device is installed directly above the doorway, window or gate, and is attached using brackets or threaded rods. The vertical heat curtain is mounted from one or both sides of the door. The height of the device should occupy three quarters of the height of the doorway. Horizontal models are more cumbersome and are not suitable for small rooms. Universal curtains can be mounted both vertically and horizontally. It is such a mobile design that is the most sought-after, since it is a full-fledged additional element of heating. It is often used for office space and apartments.
Important! Horizontal devices are not designed to install vertically.
By type of installation there are suspended and embeddable models. The first option is attached directly to the wall. The second is embedded in the wall or ceiling at the height of the opening. Such models consist of a module and a decorative lattice.
Helpful advice! Very aesthetic will look like a heat curtain, built into the suspended ceiling.
Airplane heat exchanger options
Depending on the availability and type of heat exchanger, the veins are distinguished:
- water;
- electrical;
- without heat exchanger.
The most popular and in demand are air electric thermal curtains that work from a network of 220 V. These devices have high performance and easy to install. Many models are equipped with the ability to smoothly adjust the heating temperature of the air flow. The main disadvantage of electric curtains is a significant consumption of energy resources associated with ensuring the operation of the fan and heat exchanger heating. In addition, the devices have some inertia at startup, i.e. To exit versions on the operating mode, a certain time is required.
For water thermal curtains at the entrance door having a serial designation RW, hot water appears as a coolant. Devices are connected to a heating system or centralized hot water supply through nozzles that are located in the curtain housing. The main advantage of this type of devices is the minimum operating costs. Here electricity is spent only on the operation of the fan and the control system. However, the device is characterized by a mass of difficulties in the installation process. Here you should additionally mount pipes with shut-off reinforcement and adjusting valves.
When installing a water thermal curtain, it is necessary to provide a branch from the total circuit in advance, which is not always possible with the already mounted heating system. Also, for a tube heat exchanger, you must install the filtering device to eliminate its upstream. When choosing a curtain, it is necessary to take into account the installation power, which must comply with the capabilities of the heating system so that the operation of the device does not affect the level of heating the radiators.
Air curtains without heat exchanger RV series are not used to heat the air. They are used to protect the room from the ingress of street dust, insects and various contaminants. They also warn leakage outside air conditioned air. They are often used to zoning the room in production workshops, to exclude in the storage or freezing chambers of warm air.
Electric thermal curtains over the door
As a heat exchanger, a TEN, a spiral or ceramic heat exchanger can be used here. Devices with a spiral are the cheapest and at the same time low-power. You can buy a thermal veil over the door in 4000 rubles. Due to the fact that an open-type heat exchanger, it very quickly heats the air flow by leaving the operating mode. However, such a heating element burns oxygen. The curtains with the spiral are characterized by the minimum service life.
Helpful advice! Devices with a helix are advisable to use for rooms with a high air exchange rate.
More effective are curtains with ten. It is a metal tube, in the middle of which is located heating element, wire or graphite, and sand. These devices do not burn oxygen indoors, work for a long and smooth. Allocated to the available cost. The average cost of the thermal curtain is 20 thousand rubles.
The most modern are thermal curtains with a ceramic heat exchanger, which quickly warms the air to the set temperature and switches to the economical mode of energy consumption. This device not only performs the task that cuts off the outer cold air, it allows you to significantly save the energy resource. The disadvantage is considered the high cost of the heat curtain in comparison with the analogues.
Classification Curtain for purpose
Electric thermal curtains have serial designations RM, RT and RS, which indicate the purpose of the device. The low-power mini-curtains of the RS series are used for small openings of 1500x80 cm. Their capacity is not more than 500 m³ / hour. The curtains are usually installed in transport boxes, street kiosks or over customer service windows.
The most popular are the curtains of the RM series, which are used for standard openings with a height of 2.5-3 m. They are capable of pumping up to 2000 m³ of air per hour. Models usually have convenient remote blocks and remote control panels. Such medium-class devices are often used for the inlet door or to move from a cool hallway to the residential premises.

High performance devices More than 2500 m³ / hour of the RT series are designed for openings with a height of 3.5-7 m. Install such heat curtains per gate in the workshop, auto repair, warehouse or production room, at the entrance to the supermarket or entertainment center.
Helpful advice! For a wide doorway, several thermal cables can be installed, which are located in a row.
How to choose a thermal veil
For the right choice of thermal curtain, it is not enough to determine the place of its installation and the principle of the heat exchanger. You should pay close attention to the characteristics of the device:
- sizes of curtains;
- the performance of the device, which indicates the amount of air pumped air per unit of time;
- air flow speed;
- type of heat exchanger;
- power of the heat exchanger block;
- device protection level;
- management type;
- availability of additional options;
- appearance of the device.
Linear device parameters
The main parameter of the device is its length, which must completely overlap the doorway to create the necessary air duct along its entire width. There should be no clearance that contribute to the free penetration of cold and dusty air masses. The length of the devices is in the range of 600-2000 mm. For the doorway, the standard size is purchased with a veil of 800 mm.
Helpful advice! For a better effect, you should purchase a veil, which creates a airflow, wide, slightly exceeding the lumen of the doors.
If the width of the opening exceeds the length of the selected curtain model, it is better to install two units close to each other. Choosing a long model, an important nuance should be taken into account. The curtain turbine length usually does not exceed 800 mm, which is associated with increasing vibration phenomena when it is increased, and to minimize them, additional costs are needed, which will increase product costs.
In this regard, manufacturers go to some trick. The center of the device has an electric drive, on the right and left of which the turbines of the required length are installed. However, there is a significant drawback in such a design. In the central part of the device, an area of \u200b\u200breduced pressure is created through which the cold air can be freely penetrated.
Another important parameter is the length of the jet of the air flow, which should reach the floor at the rated power of the curtain. Here it is not about the height of the doorway, but on the distance of the flooring to the floor. If the air flow does not touch the floor, the lumen will arise, which will allow the free movement of drafts.
Productivity and thermal power curtains
Effective device operation depends on the density of the air flow. The internal pressure in it should exceed the external at any point of the opening. The flow rate of the flow should also be optimal and not creating discomfort for people. The minimum value for efficient operation of the device must be at least 2.5 m / s. It depends on the diameter of the fan and the speed of its rotation.
The technical passport of each device shows its performance. A properly chosen model should ensure air supply, which only on the 1/3 part is scattered down by the book, and its remaining volume returns to the room. If the device is selected with excessive performance, then a significant part of the air will be carried out from the room outward, which indicates the inappropriate use of the curtain and unjustified expenditures of electricity spent. If the curtain provides an insufficient air flow, the cold air masses will calmly penetrate the inside of the room, making the installation of the installation inefficient.
For the door opening of the standard size of 800x2000 mm, you must choose a veil, a capacity of 700-900 m³ / hour. However, manufacturers produce models with more modest parameters. Choosing a veil, the location of the entrance, temperature differences, direction and wind speed should be taken into account. All these characteristics are taken into account when calculating the thermal curtain. Therefore, for each specific model, manufacturers indicate all the necessary parameters and recommendations to install the device in the passport.
The thermal power of the curtain is not a decisive indicator when choosing a curtain. After all, the main purpose of the installation is not heating the room and maintain the optimal temperature in it. The veil should only compensate for a part of heat losses through the door. The device only helps the heating system better function, but it should not be replaced. However, in practice, the installation of a 2 kW warm curtain is justified as an additional heating. Most models provide a temperature increase of up to 20 ° C. In some cases, this value reaches 30 ° C.
Defense protection and device management system
For each model, the thermal curtain provides two levels of control. Using the first, the specified device performance is created and supported. The second is responsible for the operation of the heat exchanger unit. A specially developed protection system eliminates the inclusion of the heater during a non-working turbine, which will protect the device from overheating.
In the most budget models, the level of heating of the TEN is already installed and the performance of the device that cannot be changed is set. However, to independently regulate the microclimate indoors, it is better to choose veins with the possibility of manual control of the device. There are also complex options where the stepped adjustment of the curtain, which provides several levels of the power of the turbine and gradation of the heat exchanger heating.
Most popular today are electronically controlled models that allow smooth and accurate adjustment of the device. Usually the control unit is located on the device housing. You can also buy a heat curtain with a control panel or a remote block, which is located on the wall. A number of buttons are located on the panel, with which the effective work is configured: Turning on / off, performance, heating mode, temperature, etc.
Each modern model is equipped with an increased degree of protection against overheating, voltage drops, short circuit, phase breakdown on the housing and other protection options. There are also models that are equipped with a thermostat and timer. In newer versions, the air supply angle is regulated, which increases the efficiency of the curtain.
Installation of thermal curtain
Despite the fact that the degree of complexity of the installation of the device is much easier than for a household air conditioner, the manufacturers insist entry the installation of the veil to a professional. However, you can perform work independently.
Before you begin installing a heat curtain, you should provide a power line of the required power, the point of connection of the device, protective and safety elements (Uzo and automatic). Next, you should perform accurate marking, after which the mounting parts are fixed on the wall plane for further hanging the thermal curtain over the door. The device kit usually includes a mounting panel or brackets and fasteners.
If the selected curtain model has adjustable, they must be tilted from the vertical at an angle of 30 degrees. in the side of the entrance. The design of the air nozzle of many models already has such a bias of the air flow. You may also need to install a signal cable and fixing the remote control panel on the wall. All these steps are described in detail in the installation instructions for the installation of the device with which you should read before installing the curtain.
The installation of a horizontal or vertical water heat curtain is a more complex event that requires certain thermal calculations and installation of additional pumping or collector equipment. To carry out installation, you should attract specialists in this issue.
Repair of thermal curtains
To estimate the scale of the breakdown of the veil and the possibility of its repair can only be a qualified specialist. It will easily change to a new detail, and follows the subsequent configuration of the device.
The most common cause of the vehicle breakdown is the overheating of the device, which occurs due to non-compliance with the recommendation of the instruction. The curtain turns on complete power, as a result, the fan, the heating element, the relay occurs, fails and the electrical contacts suffer. Most often fail the curtains with a length of the device more than 80 cm, which are equipped with a very difficult package.
The service center specialist can eliminate a small malfunction in place. However, if more complex repairs are required, the equipment is dismantled for a while. You can also try to eliminate the fault yourself, having examined in detail before this instruction.
All work must be carried out in compliance with safety. If the device does not turn on, first should be ensured in the presence of electricity. Then check the contacts and fuses. Faulty elements can be changed independently by following instructions.
Important! All work with the device is performed when it is completely disconnected from the network.
If the device switch is in the "heating" position, but the function is not performed, the switch may be out of order, or in the electrical circuit bad contact. In the first case, the element changes to a new one. In the second embodiment, check the correctness of the connection, and restore contact.
If the heat curtain is periodically turned on and off, it is necessary to check the correctness of its installation and clean the inner part of it from the accumulated dust.
Important! The device will work properly when all recommendations on its installation, maintenance and periodic cleansing are performed.
Planned maintenance of thermal curtains
To ensure efficient and long-term operation of the heat curtain, it is necessary to clearly follow the recommendations specified in the instruction manual of the device, which needs timely professional maintenance.
Every month it is necessary to perform an external inspection of the device, check the attachments, fencing and block design. For each phase, the current and voltage check is performed. The heat curtain in all its modes and control panel should be tested. Cleaning the case, front panel of the control unit, input blinds and air filters.
Once a quarter, a qualified specialist pulls the threaded connections of wires on terminal boxes, performs stripping contacts, checks the operation of fuses and tips. In case of detection of faulty parts changes them to new ones. Also performs the diagnosis of the veil to identify and eliminate foreign noise. A survey of fan blades is carried out.
Each half of the year should be performed by the seasonal debugging of the operation modes of the device, which lies in the coloring or conservation of the thermal curtain. At this time, pneumatic cleaning of the heat exchanger and the rest of the nodes is also performed.
It is possible to purify the heat exchanger annually using a special chemical composition. It also establishes the degree of wear of the bearing of the fan electric motors.
