Thermal curtain on front door- one of the innovations of our time. The purpose of this equipment is to create a protective barrier between the atmosphere inside and outside the room. The principle of cutting off cold air masses using a powerful air flow has long been used in construction and industry. But devices for protecting apartments have recently appeared on the market.
Heat curtains are one of the types of heaters that operate on the principle of a fan. Externally, the device looks like a household air conditioner:
The unit differs from heaters in that they increase the air temperature in the room. This is their only task. The thermal curtain has two of them:
The use of a thermal curtain for the entrance door allows you to save on heating the room during the cold season. Experts report that with the help of this device, electricity costs are reduced by more than a third. The savings are due to the absence of the need to connect other heat sources.
Thermal curtains belong to the category of semi-industrial heaters, so most devices have a discreet design and laconic forms. But the leading producers of this equipment understand that such devices do not always fit harmoniously into the interior of modern city apartments. And offer it to consumers designer models having more attractive appearance. The front panel of such devices is made of impact-resistant glass in black or white.
All thermal curtains are designed and operate on the same principle.
All types of thermal curtains are designed according to the same principle
The devices are equipped with two types of blower fans:
The device is controlled using buttons on the front panel or remote unit, as well as using the remote control. The device can be equipped with an air temperature control sensor. Most models are equipped with a power cable for connecting to the mains. But there are devices on the body of which only a terminal block is installed.
Installing a thermal curtain over the front door has a number of advantages. The main advantage is to increase the level of comfort of living in the apartment. This is ensured by several effects:
No disadvantages of using thermal curtains were found. Equipment in this segment is not a necessity, but its installation significantly improves the quality of life.
Equipment in this segment is classified according to several criteria:
Based on the type of installation, there are two types of models:
Devices of the first type are needed where attachments inappropriate or does not fit into the design of the room. Built-in models will help out in situations where the height of the lintel above the front door does not allow the installation of attachments.
Devices of the second type are the most commonly used in city apartments and private houses. They are installed on a wall or ceiling using brackets, take up little space and do not interfere with entry and exit.
Based on the type of location, there are several types of thermal curtains:
The most popular and convenient devices are the first type: horizontal. They are installed directly above doorway and supplies air flow in the direction from top to bottom. Installation is carried out in two ways:
Horizontal models can be installed on both sides of the opening, but such installation is unreasonable for city apartments. It is used to cut off cold air at the entrances to public places.
Vertical ones have more compact dimensions than horizontal ones. This is due to the peculiarity of their installation: on the right or left side of the door. It is permissible to install equipment whose height does not exceed 1/3 of the opening height.
Universal models can be installed in any position of the housing: vertical or horizontal. The mobility of such curtains has led to a higher demand for them than for other types of devices. Universal equipment in demand in administrative buildings, city apartments and private houses.
According to this criterion, three types of curtains are distinguished:
Most models of this type are equipped with a temperature controller. This is a justified decision, since the energy consumption of the curtains is quite high. When it gets warmer outside, you can adjust the device so that it produces cool air. A distinctive feature of this type of equipment is its inertia. In order for the device to reach operating mode, it needs some time, since the heat exchanger must heat up. For more powerful devices this process occurs faster.
The first models of thermal curtains used spiral heat exchangers. They have many disadvantages, the main ones being the “burning” of oxygen and dehumidification of the air in the room. Over time, most manufacturers abandoned this type of heat exchangers and in modern air curtains they install tubular or air-conductor ones. Such models always have a heating control function.
Equipment of this type (serial marking RW) has lower power consumption, since they only need electricity to operate the fan and control system. In these models, the coolant that heats the air flow is hot water. In this regard, installation of equipment is complicated.
Water-type thermal curtains consume less electricity
The heat exchanger consists of thin pipes and resembles a car radiator. The water circuit is connected to the water supply through pipes located on the side panels of the device. It is also necessary to install a pipeline leading to the water intake point. The connection can be made to a heating or hot water system.
The second option is preferable because if the heating is turned off, heating will not be possible. But this is not a reason for disappointment, since the heating is turned off when the average daily temperature is positive and there is no need to heat the room.
Installation of a water heat curtain is also complicated by the fact that it requires an additional branch from the general circuit of the utility network. It must be provided for at the installation stage of the water supply distribution. Subsequently, it will be impossible to connect the equipment without damaging exterior finishing premises.
An important design element of the device is a filter that retains sand and other impurities in the water. Since its quality often leaves much to be desired, regular filter cleaning will be required.
Serial marking of air curtains without a heat exchanger is RV. Equipment of this type performs only one function - cutting off air masses located behind the front door. But at the same time it protects inner space from smog.
Heat guns are also used as an additional heat source. Review of models in our next material:
When choosing a thermal curtain, the first thing you need to pay attention to is power or air flow. Equipment with a low pumping rate is not able to cut off drafts and odors, while equipment with excessively high power causes a feeling of discomfort and heats not only the room, but also the street.
Based on performance, all thermal curtains are divided into three categories:
Air curtains of the RS series are low-power, with a capacity of no more than 500 m³/hour. These are inexpensive models that are installed in openings no more than 150 cm high and up to 80 cm wide. They are not suitable for installation above the front door in apartments and houses. This requires medium-power models, the RM series.
These devices are installed in openings with a height of 200–300 cm. The equipment productivity is 1,500–2,000 m³/hour. Most manufacturers of thermal curtains of this series equip their products with remote units, which are installed in any place convenient for the owners. The equipment is controlled not only with the help of these units, but also with the help of remote controls (remote controls).
RT series devices are characterized by high productivity: more than 2500 m³/hour.
If equipment is chosen as the main source of heating the room, you will need a device with a power of 40 W/m³ of heated space. To provide additional heating, a device with a power of 20 W/m³ is sufficient. If the space in the apartment is wide, you can install several devices in a row.
One of the most important parameters- length of the device. It should match the width of the doorway or overlap it. Otherwise, there will inevitably be gaps through which cold air. The retail chain offers models with a length of 60–200 cm. For standard openings in apartments and private houses, equipment with a length of 80 cm is purchased.
In most cases, for the improvement of apartments, thermal curtains are purchased that operate on electricity and with a tubular or strip heat exchanger. It is easier to install such equipment than an air conditioner. But despite this, manufacturers insist that installation be carried out by specialists. However, any owner who knows how to drill walls and screw in self-tapping screws will be able to install a thermal curtain with his own hands.
You can install the thermal curtain yourself
For equipment with remote control, installation of the unit is required, which is carried out in several stages.
During installation, it is important not to touch the electric motor, as there is a risk of disturbing the alignment of its shaft and impeller. This can lead to noise and vibration during operation of the air curtain.
The Termomir store offers customers a wide range of thermal air curtains. Heat curtains are sold wholesale and retail on the official website.
One of the most effective options for protecting against the penetration of cold air into a room is a thermal curtain. Using a wide air flow, the device separates the heated room from the cold air from the street, protects against dust and insects, provides a comfortable microclimate in the entrance area, saves energy resources for heating, and in the summer keeps air-conditioned rooms cool.
Air curtains are installed on entrance groups buildings with big amount visitors: in shopping and entertainment centers, metro lobbies, cafes and restaurants, large offices, banks, clinics, etc.
Curtains come with heating - electric and water (on hot water), and also without heating - air.
Electric heat curtains operate from the mains, can be used for both domestic and industrial purposes, usually have several operating modes with power switching and can operate without heating (summer mode). Air curtains with a power of up to 5 kW operate at a network voltage of 220 V, and from 5 and above - 380 V. Household air curtains are actively used for doors in country houses and dachas.
Water thermal curtains differ from electric ones in much greater power, therefore they are actively used for large objects - doorways and gates of large warehouses, shops, workshops, hangars, etc. Such curtains have permanent installation, are connected to the main hot water and are characterized high efficiency and air performance.
Air curtains without heating are used where it is necessary to separate the zone of heat and cold without additional heating. These devices are not equipped with heating elements, but work like large fans, allowing you to separate refrigeration chambers, areas or warehouses with refrigerated products, prevent smoke and dust from entering other rooms, for example, in working workshops and workshops, etc.
Thermal air curtains have basic technical characteristics: power, air capacity and installation height. Based on these parameters, the calculation and selection of heat curtains is carried out. The dimensions, or rather the width of the curtain, are also important - it should be sufficient to cover the entire doorway, providing complete protection.
Thermal curtains are most often produced in a horizontal design and are placed above a door or gate on the wall or ceiling. Veils vertical installation are located on the side of the doorway and have important characteristic no longer width, but height. Sometimes, at high doorways, several such curtains are used, installed one above the other. There are also models universal installation, which are connected from the side or from above at the user’s request. Thermal curtains quite often come with a remote control - keypad, wired or wireless. This device greatly facilitates the use of the curtain and increases comfort. A large assortment of thermal curtains is presented below on the page and in the site menu. If you find it difficult to make a choice, contact our specialists for advice.

Administrative buildings and residential premises, regardless of region, affiliation and geometric dimensions, are equipped with utility networks, which include water supply and sewerage networks, electricity supply and heating. provide the required indoor microclimate, which is expressed in maintaining temperature and air humidity, as well as maintaining other indicators at specified values. All users know about it as an element of the heating system, but not everyone knows what an air curtain is, much less what tasks such an installation can handle. Thermal curtain for the front door - what it is and how it works, types and features of installation, maintenance and repair, as well as the secrets of choosing a smart curtain and a review of popular models - all this in detailed review editorial website.
The Frico PA2210 CE03 model is equipped with a control panel that allows remote control of the operating modes of the heat curtain
A thermal curtain is an element of a utility system that serves to cut off outside air from the internal volume of a building by creating. The air flows created prevent the entry of cold or warm air(depending on the need), dust or gusts of wind, as well as insects and vehicle exhaust gases into the interior space. The operating diagram of the thermal curtain is shown in the following figure.
According to the principle of its operation, a thermal curtain resembles a heat fan, in which air flows passing through heating elements are heated and distributed in a given direction. A distinctive feature of the fan is the narrowly directed movement of strong air currents moving along the plane of the doors at which it is installed, creating an invisible barrier to outside air. The main technical characteristics on the basis of which such devices are selected are the following indicators:
Technical characteristics serve as the main criteria for selecting such devices, determining the location and type of installation, type of energy source and heating element.
Depending on the design, household appliances may vary in location relative to the doorway; they come in the following types:
Models with vertical placement are used in cases where it is not technically possible to install horizontal analogues.
Important! When selecting a vertical thermal curtain, you must remember that its length must be at least ¾ of the height of the opening at which it is installed, otherwise the device will not be able to provide the required air barrier.
The selection of a thermal curtain is also carried out according to the type of installation, which determines the type and presence of an energy source: electric, water and without a heat exchanger.
How to choose a thermal curtain and what to pay attention to are the questions that face potential buyer, when a decision is made about the need to install such equipment. Among the selection criteria, an important indicator is the type of thermal energy source through which the air flows are heated.
Electric Zilon models are easy to install and easy to use
Electric air-thermal curtain– this is a device in which air is heated when it passes through an electric heating element (heating element, spiral, stich elements). This type of installation has a number of advantages in comparison with other analogues:
The disadvantages of air curtains equipped with an electric heat exchanger are:
A water heat curtain is another type of device of this type, distinctive feature which is a heat exchanger made in the form of a water heater. This type of installation is usually used in public, administrative and industrial buildings, which is due to the design of the heat exchanger and the need to connect to the heating circuit of the building (structure).
This type of curtain is connected to the system central heating, and the coolant circulating through the heater transfers its thermal energy to the air also passing through it. The advantages of units of this type are the following indicators:
Disadvantages include:
Manufacturers produce air curtains in various configurations, corresponding to the stated consumer specifications, standard configuration or without a heat exchanger. These may be ordinary models that do not have electric heating elements or a heater. In this case, the air curtain operates as a simple fan with a narrowly directed air flow distribution.

Traditional water system heating has quite a few advantages, but it also has many disadvantages. And one of them is high price at the device stage and the complexity of installation. Therefore, many are looking for ways to heat a house or apartment without radiator systems. This can be done using autonomous heaters. They are different types and types, they can run on electricity (most models) and gas (much less). Let's talk about how to choose a heater for a house, apartment, room or cottage.
The easiest way to heat a room is to use an electric heater. All of them do not require any special conditions to connect. You can put them up or hang them up, plug them in and that’s it – your heating works.
In order to heat a room of up to 15-20 square meters, a 2 kW heater is sufficient. The time it takes for the temperature to become normal depends on many factors, but he should be able to cope. If the insulation is normal or good, there is no blowing from the windows and doors, the heat will become quite quickly. Otherwise, you will have to wait, although you can use a more powerful heating device.
If you need to warm up whole house or apartment, first you need to decide on the allocated power supply. What power is allocated to the apartment can be found in management company. But, in general, if the year of construction is before 2005, 7 kW is 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 your home, you need to decide what total power you need for electric heaters. For rooms with average thermal insulation for Middle Strip In Russia it is generally accepted that 100 W per square meter. But this is for standard height- 2.7 - 3 m. Some types of electric heaters for the same conditions require less power, but approximately, they calculate 100 watts per square meter. If the resulting figure “fits” into the power allocated for the house or apartment, great. Just keep in mind that you have a lot of other equipment and you need a certain resource for its operation. If this is not taken into account, the circuit breaker will often trip in response to overloads.
And one more point that is often forgotten. When determining the power of heaters for your home, do not forget about the level of “heat-lovingness” of the inhabitants of the apartment or house. For someone optimal temperature- 20-21°C, but some people feel normal only at 25°C. If you are a heat-loving creature, add a power reserve of 20-25%. He is the one who will create comfortable conditions for you.
Of course, it’s easy to install an electric heater for your home - just plug it in and there’s no problem. But electric heating- the most expensive, so many try to choose the most economical type.
When choosing a heater for your home, pay attention to efficiency (efficiency factor). Equipment of the same type, but from different manufacturers, can differ significantly in efficiency. For example, you can supply two 2 kW convectors from different manufacturers in absolutely identical rooms. And it may be that it will be warm in one room and cold in another. It's all about the efficiency of converting electricity into heat. In the case of a “cold” room, a significant part of the energy is lost. Such heating certainly will not be economical.
The efficiency of the device is very important point: fan heaters can also heat air with different efficiency
If we talk about energy efficiency, then according to reviews from owners and operating experience, you can arrange electric heaters for houses and apartments in the following order:
Heat guns - this design cannot be called interior design
Let's summarize. If you want to choose heaters for your home and not go broke on heating, then the most economical electric heaters are infrared, followed by convectors with a monolithic heat exchanger and an electronic temperature sensor, then convectors with other heating elements. The average efficiency ones are fan heaters, the most uneconomical ones are oil radiators.
While the power supply in cities is stable, rural areas are often left without electricity. Moreover, interruptions occur most often in the worst weather. This is understandable, firstly, electricity consumption increases these days, and secondly, in bad weather, power lines fail. Therefore, they often try to make home heating energy-independent - in order to be warm all the time. If you do not consider stoves and potbelly stoves, there are the following options:
Of all the non-electric heaters described above, the ones most suitable for home use are gas convectors. They were developed as household heating devices and the level of comfort is high. Fuel infrared and heat guns are more equipment for heating technical or production premises. They look unsightly - like industrial equipment. True, fuel infrared heaters are good for heating open areas, gazebos, etc.
Quite often, electric heaters are used to quickly warm up the air in a room. It could be a bathhouse, a dacha. There may be a stove in them, but it takes a long time for it to heat up on its own and begin to warm the room. To avoid freezing during this period, a high-performance heater is required. These tasks are handled well:
In general, if you need to choose a heater for your home that will quickly heat the air, the best option — heat gun. Others are not as effective. In order for the room to warm up faster, take units with a large power reserve. Only in this case can you expect quick results.
For normal well-being, it is very important that the air we breathe has a sufficient level of oxygen. If a home heater uses an open fire, it will certainly burn oxygen. Another issue is that not all devices use oxygen from indoors. For example, parapet gas convectors take air from the street through coaxial chimney. That is, they have almost no effect on indoor air quality. For other models - with an open burner - it is necessary to have supply ventilation. And if you need home heaters that do not burn oxygen, pay attention to electric models.
In the case of electric heaters, the situation is different. As a rule, the heating elements in them do not heat up to temperatures at which oxidation reactions occur very actively and the oxygen level is significantly reduced. But if you don’t ventilate the room, your health really gets worse. Why is this happening? The fact is that if the heating element is heated to 600°C, this is enough to burn dust and other organic residues that are present in the air. During the combustion process, oxygen is, of course, used, but not in such quantities that can significantly affect its content.
During the combustion of dust, gases are released (including carbon monoxide), which give bad smell air and affect your well-being. It is this phenomenon that is called “burns oxygen,” although in fact it is not so. However, when choosing a heater for your home, it is advisable that its heating element is not too hot. The highest threshold is 500°C, but 350-400°C is better. Also, make sure there is good ventilation. This is the key to good health with any heaters.
The equipment listed above does not heat up to high temperatures. However, even with a working oil radiator, which can only heat up to 60-70 degrees, a feeling of “lack of air” may occur. This feeling disappears after airing. So ventilation is very important and necessary. And in order not to worry about the heated air leaving the room, ventilation openings are made with recovery (removing heat from the exhaust air). In this case, not cold air enters the room, but slightly heated air.
The choice of a heater for a balcony or loggia depends on the degree of insulation. If there is sufficient insulation and double-glazed windows, it will be possible to install a convector. Its power depends on the area of the balcony, but it can be calculated as for ordinary premises: 100 W per square meter.
On glassed balcony Infrared heaters can also be installed. And they will cope with the heating task very well. They just cost more than convectors, but consume less electricity. So it's a good option. If you want to make your balcony habitable and comfortable even in cold weather, consider installing a heating carbon film. It can be mounted on walls, floors, ceilings. Just for it to be effective, it requires very good insulation and a heat-reflecting layer on top of the thermal insulation. But it will be very warm.
If there is almost no insulation and you have ordinary frames, but you want to spend some time in relative comfort, you can consider options with heat guns. They will heat such a volume from frost to above-zero temperatures in a matter of minutes. But this is provided that there are no holes. If the frames are “conditional” or there are none at all, you will have to choose an infrared heater for the balcony. It will not warm the air, but you. So you can choose a heater for a balcony, you just need to clearly understand what you want to have - additional warm living space or relative comfort for a while.
Preventing heat loss through doorway is relevant in rooms where entrance doors are often opened. For this purpose, a thermal curtain is used, which is modern and functional equipment. Right choice Such devices require taking into account many criteria, but as a result the device will work correctly and for a long time.
A type of climate control equipment is a thermal curtain, which is an oblong metal case with internal fan, heating device, nozzle and other elements. A complex of such parts is connected into a whole system inside the housing, which ensures prompt heating of the air, the flow of which enters above the front door, as if cutting off the cold from the outside.
Inside the housing, the air is heated and enters the room
Each component of the system performs a specific function. For example, the heating element in electric models is presented in the form of a heating element, around which air is circulated using a fan, and when heated, it is discharged outside through nozzles. The speed of such an air circulation can be adjusted depending on the temperature required for the room. When moving, the air is cleaned through a filter from dust, dirt and debris. All elements are enclosed in a housing equipped with mounting holes.
The design of the equipment includes elements with simple principle actions
There are water models of thermal curtains. Such devices use a heater as a heating element, and operation requires a connection to a hot water supply. The noise level of the device is quite low compared to electric options, which are in demand and are often installed in stores, public spaces.
The equipment can provide vertical or horizontal air supply. In the first case, the device is mounted above the doorway along its entire width.
Horizontal placement of the thermal curtain is popular and convenient
If horizontal airflow is required, then a thermal curtain is attached to each side of the opening along its entire height. It is possible to install the element on only one side, but this requires a device with high power and high operating speed.
Modern electric-type models can be used not only in the cold season, but also in hot weather. In the first case, the thermal curtain prevents cold from entering the room from outside, and in the second, the device functions as a fan. Therefore, the purchase of such equipment is cost-effective, and a practical device will not remain unclaimed in any weather.
The thermal curtain does not take up much space and is easy to install
Since electric curtain models are in demand, it is worth considering the features of choice using the example of just such devices. You need to focus on the characteristics. One of important indicators is power or productivity, indicating how much air the device can heat over a certain period. Determining the optimal performance required for a particular opening is influenced by the installation height of the curtain. For example, for standard opening 1 m wide and 2 m high will require a device with a capacity of about 900 cubic meters per hour. At the top, the air flow speed will be equal to 8–9 m/s, at the bottom 2–2.5 m/s, which ensures complete coverage of the entire opening by the air curtain.
Public spaces require efficient and high-quality thermal curtains
The type of heating element matters if long-lasting equipment is required. The air can be heated by a heating element or a spiral. The first part is a graphite rod in a steel tube. The design is characterized by complete safety, long service life and fast heating. The spiral is made of thick nichrome wire, and its operation requires a lot of energy. The element is short-lived, but heats up quickly.
