Thermal curtain on the front door: selection rules and recommendations. Which heater is better for a summer residence Electric heat exchanger for an air-thermal curtain

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 a modern and functional equipment. Right choice such devices require many criteria to be taken into account, but as a result the device will work correctly and for a long time.

Thermal curtain on the front door: purpose and device

A type of climatic equipment is a heat curtain, which is an oblong metal case with an internal fan, heating device, nozzle and other elements. A complex of such parts is connected into a whole system inside the case, which ensures prompt heating of air, the flow of which enters above the entrance door, as if cutting off the cold outside.

Air inside the housing heats up and enters the room

Each component of the system performs a specific function. For example, a heating element in electric models is presented in the form of a heating element, around which air is driven by a fan, and when heated, it is brought out through the nozzles. The speed of this air circulation can be adjusted depending on the temperature required for the room. When driving, the air is cleared through the 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 a simple principle of operation

There are water models of heat curtains. A heater is used as a heating element in such devices, and a connection to a hot water supply is required for operation. The noise level of the device is quite low compared to electrical options, which are in demand and are often installed in shops, public premises.

The equipment can provide vertical or horizontal air supply. In the first case, the device is mounted above doorway across its entire width.

Horizontal placement of the heat curtain is in demand and convenient

If horizontal airflow is required, then the heat curtain is fixed on each side of the opening along its entire height. It is possible to install the element only on one side, but this requires a device of high power and high operating speed.

Choosing a thermal curtain for the front door

Modern models electric type can be used not only in the cold season, but also in hot weather. In the first case, the heat curtain prevents the cold from entering the room from the outside, and in the second, the device acts as a fan. Therefore, the purchase of such equipment is cost-effective, and a practical device will not remain unclaimed in any weather.

Thermal curtain does not take up much space and is easy to install

Since electrical models of the curtain are in demand, it is worth considering the features of the choice using the example of just such devices. You need to focus on the characteristics. One of the important indicators is the power or performance, indicating how much air the device can heat up over a certain period. The installation height of the curtain influences the identification of the optimum performance required for a particular opening. For example, for a standard opening 1 m wide and 2 m high, a device with a capacity of about 900 cubic meters / hour will be required. At the top, the air flow speed will be equal to 8-9 m / s, at the bottom 2-2.5 m / s, due to which the entire opening is completely covered by the air veil.

In public areas, productive and high-quality thermal curtains are needed

The type of heating element matters when durable equipment is required. The air can be heated with 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 high energy consumption. The element is short-lived, but heats up quickly.

Curtains with any heating element are practical, easy to use and effective

The control system can include only three buttons: general activation, fan regulation and activation of the heating component. Models with these basic controls are inexpensive and easy to operate.

Devices with more than three buttons are functional. Such equipment has a timer, adjustment of the angle and air flow rate, control of the installed thermostat. The cost of such devices is higher than with the main buttons and without a thermostat.

The modern thermal curtain is easily adjustable using buttons

In addition to the above criteria, when choosing a thermal curtain, such features as:

cost. Inexpensive and simple models suitable for intermittent operation, and powerful options are optimal where good additional heating of the room is required and with frequently opening entrance doors;
length. This parameter is selected depending on the width or height of the opening. It is permissible to mount several devices in one row to provide a dense curtain of warm air;
manufacturer. Companies with many years of experience in the manufacture of climatic equipment are well known and provide a wide range of devices, a warranty period, and unpopular brands often produce inexpensive and insufficiently reliable products.

These criteria are basic and allow you to determine the device with the required characteristics, which will be efficient in operation. Having decided on them, they select suitable model climatic equipment.

How to install a heat curtain

Installation of electrical type thermal equipment does not differ in complex technology, since all the necessary elements and holes are provided in the case. Water systems require connection to hot water supply and therefore are not in demand, and their installation is carried out by professional craftsmen.

Water models of the heat curtain require connection to the water supply system and the exact location of the pipes

Installation will require anchor bolts, brackets, a drill, a building level and a tape measure. First, you need to provide a power line for the equipment, the presence of safety and protective elements, that is, an RCD and an automatic device. After that, mark with a pencil the location of the device.

The main stages of work are expressed in the following:

Video: overview of the design of the thermal curtain

Correct use of equipment

Climatic equipment quite unpretentious in operation, but manufacturers recommend following certain rules for using devices, which is especially important for electrical models. Basic tips:

it is forbidden to operate the heat curtain in rooms: with an explosive, bioactive and dusty environment or with an environment that causes corrosion of materials. The thermal curtain must not be used in rooms with a relative humidity of more than 80%. Long-term operation of the curtain in the absence of personnel is prohibited. It is not allowed to operate the device without grounding. Do not turn on the device with the cover removed;
the devices are intended for use in areas with a temperate and cold climate, in rooms with an ambient temperature of -10 ° C to +40 ° C and a relative humidity of no more than 80% (at a temperature of +25 ° C in conditions excluding contact with it drops and splashes, as well as precipitation);
the device must be connected to the mains using a power cord equipped with a plug to ensure that the device is disconnected from the power source. If connected directly to a fixed wiring, a disconnector must be provided in it to disconnect the device from the network. Take special care when transporting the instrument. Its fall is not allowed;
it is strictly forbidden to eliminate coolant leaks on the fan heater, the water line of which is under pressure. The device must be connected only through a shut-off valve.

To prevent cold air from entering the apartment from the street, you can find on free sale special device... This is a heater above the front door, which has electronic control, a remote control and several operating modes. The unit itself is quiet and compact, its presence in the house is sometimes simply irreplaceable for all household members.

Heat curtain - what is it

In fact, it is a cold air separator for the entrance doors, which works on the principle of a thermal fan. It protects the premises from drafts, and its inhabitants from cold and disease. The installation can be vertical and horizontal, but the functions are identical - to provide heat supply, exclude cold air from the street. The heat curtain operates from the mains, the working voltage is 220 volts. If on front door to hang such a unit, there will definitely not be dissatisfied with such an innovation.

How the heat curtain works

A progressive thermal curtain device is specially designed for climate control in a room of any size. Its installation is relevant for the front door, while the range of action is limited. To understand how this unit functions, you need to carefully familiarize yourself with its structural elements. This is a metal case, a fan, an air heater, nozzles for a jet outlet. Additionally, a sensor and other devices can be installed for rapid heating of air, monitoring the air temperature in the doorway.

Electrical

There are several types of curtains, which differ in their principle of operation and installation method. In the first case, an electric heat curtain, which operates from a 220 V network, is especially relevant. For such character models, not only vertical / horizontal installation, they can be installed on the side in the door openings. The main heating element is an electric coil, and the warm air is circulated by a classic fan. For home use, this is a great option, since the heat curtain has a discreet design and compact dimensions.

Aquatic

Compared to the previous sentence, this a budget option, which in the process of use has several advantages. Among those dimensions, low noise level during operation, overheating protection system, economical power consumption, reasonable price. The scheme of operation of air-thermal water curtains is based on heating the main element, which is a heater. It is characterized by increased stability in relation to sudden changes in ambient temperature, has a long service life, and high technical characteristics.

Types

The second classification of thermal curtains on the front door is carried out according to the method of installing the structure in the doorway. For a living space, it is very important not to spoil the interior and not litter the space with unnecessary items. Studying existing species thermal curtains, it is possible to decide which option is optimal in a particular case.

Vertical

Such models are considered popular, since they are imperceptibly fixed over a door or window opening across the entire width. Vertical air curtains provide a stable barrier, and sufficient heat remains in the room for a long time. Wall mounting requires certain skills, therefore, it is especially convenient and simple not horizontal, but floor installation... Such mobile structures are more popular every year.

Electric horizontal

Knowing how the unit works, it is important to correctly install it in your apartment, use it for its intended purpose. The horizontal thermal curtain is attached to the entrance opening on the sides, it is used in the presence of suspended ceilings or not free space over the door. Such models are particularly bulky and are not suitable for apartments with small corridors. In this case, the heat curtain on the front door will only interfere, constantly catch your eye.

Embedded

When buying a thermal curtain on the front door, installation behind a suspended ceiling or installation in the opening of doors and windows is appropriate. Modern models are equipped with additional features to eliminate condensation. Universal air curtains are considered a full-fledged heating element, suitable for home use and installation in office premises. You can find a suitable design on the Internet or contact a specialized store for the help of a consultant. Thermal curtains over the door are inexpensive, order and buy in the online store is cheaper.

Heating curtain performance

Taking into account the density of the air flow and the footage of the living space, you can choose the right thermal curtain for the front door. The power of the structure (in kW) determines. How much air is able to pump through the unit per unit of time. You should not save on such an indicator, otherwise the heat curtain will create insufficient heat, and the draft will still penetrate the room. The cost of the heat curtain and the receipt of the desired effect by the buyer depend on such a technical indicator as power.

Questions about how to insulate iron door in a private home, on the Internet, there are much more than intelligible answers to them. Rather, there are answers and even a lot, but they are basically such that they give rise to even more questions, because most of them do not solve problems at the root because of fundamental errors in approaches.

Let's try to figure out, as they say, "on the fingers", what are the main mistakes in the insulation of the front door in a private house, and what needs to be done to prevent them.

The picture shown in these photographs is seen quite often. Rather: almost always, if a steel door, even a very good one, is installed without the so-called cold vestibule and is the only barrier between a warm room and a cold street.

99% of "iron" doors, even with the most careful factory insulation, are not devoid of cold bridges, leading to just such consequences. It would seem that the door, the section of which is shown in the photo below, is thoroughly insulated.

But the stiffness profiles, the ends of the door leaf and the frame are precisely those cold bridges that, with a slight frost, will provide you with a large amount of condensation, and with a thorough frost, which sometimes happens in Mother Russia, they will lead to the formation of ice. Why is this happening?

Reasons for freezing an iron door in a private house

When does moisture begin to form on the frame and door leaf? Then, when their temperature becomes such that the vapor of the air in contact with them begins to condense into dew. With stable conditions (cold outside - warm inside), the resulting condensate flows down, and a new one forms in its place. Such a minifactory for the production of water is capable of producing up to several buckets per day.

If the outside temperature drops further (or the inside temperature drops), the condensed moisture will freeze and ice will form. And in the presence of cold bridges, this process cannot be stopped, no matter how insulation material you haven't laid inside the door. And at the factory they lay anything:

I think it is not worth describing in too much detail that under certain temperature conditions, moisture will necessarily condense not on the inner surface of the door, but on the inner surface of the outer sheet of its door leaf. What will happen to her in this case? Definitely, it will be absorbed by a cotton wool insulation to full saturation, which will lead to:

the loss of its thermal characteristics by the insulation;
the formation of voids due to the subsidence of the cotton insulation under the increased, due to the mass of water, its own weight;
the creation of a corrosion center is almost always not the best protected internal metal surfaces of the door;
the emergence of a favorable environment for the development of mold, fungi and the residence of harmful microorganisms.

To the quite reasonable question arising from many about why such doors are produced, there is one justified answer: for installation in apartment buildings, the temperature at the entrances of which (if there is heating in the house) does not fall below zero, even if the radiators are cut off. Heat penetrates the stairwells not only through such doors, but also through the thin walls of the apartments. After all, their owners who buy metal entrance doors are ten times more than the owners of private houses who want to do the same.

And what should these unfortunate owners of private houses do, who want to install a reliable iron door at the entrance to the house and categorically refuse to build even a cold vestibule of the smallest size - a heat exchanger, in which it will not present such surprises as described above?

Ways to solve the problem of freezing of an entrance iron door

Just search the vast market steel doors those that are produced specifically for these cases. There are actually not so many of them. Maybe even more than the 1% allocated by us, but not significantly.

In such doors, first of all, they fight condensation in two ways:

elimination of cold bridges;
by shifting the dew point from the room to the outside.

For this:

Inserts are made into the boxes, ends and stiffeners of the door from hard plastic, which interrupts the heat transfer through the metal;

Displace structural elements doors interrupting cold bridges (third photo above);

Electric heating of the box is installed, and sometimes the door leaf.

Sometimes the manufacturer uses similar methods in one door structure... Purchasing just such a door will be the first option for solving your problem. True, we would also recommend adding something to it.

Namely:

If your door has a wood trim (1) on the outside, place a thin polyethylene foam membrane underneath it, at least the one used for laminate flooring.
Installed under the decorative strip door handle and locks (10, 14), a dense plastic film, which you carefully trim along the contour after fixing them, will effectively reduce the possibility of moisture condensation on the inside of the fittings.
If any cotton wool (4) is used as insulation in your door and there is an opportunity to fix it - do it. Replace it with polyurethane foam or expanded polystyrene sheets, be sure to stick them on the foam to the outer steel door card. It is better if it is applied without gaps, which will prevent moisture condensation between the metal sheet and the insulation. Perfect option - when the dew point is in the array of this insulation. This is not cotton wool - physical water cannot form inside.
Install the outer casing (7) on the box (8) with a spacer between them, either the same as in the first paragraph, but possibly thicker (8-10 mm) polyethylene foam, or centimeter polystyrene foam.

Such a revision will definitely improve the thermal performance of your front door.

How to insulate an entrance metal door with your own hands

If your product is much less technologically advanced than those described above, you should know how to insulate an entrance metal door with your own hands, without spending more money on this business than you saved on purchasing it, opting for a cheaper option.

For this:

1) If the door leaf is collapsible, disassemble it, if not, carefully cut off the back card, either along the butt, or along the plane, depending on which insulation option you choose.

2) Remove the so-called factory insulation and select the option to subsequently close the door leaf from the inside.

If you choose the option of returning the cut card to its place with ennobling its edges or covering the cut place with some corner, do it as shown in the picture above. Please note that the rail, screwed to the bearing profile of the door leaf, has a smaller width than the inner cavity of the door, and the gap between the outer card and wooden lath must be filled polyurethane foam... Also, a bar protruding literally 1 - 1.5 mm above the profile pipe will break the direct metal-to-metal contact, and hence the notorious cold bridge.

3) Select the insulation and the procedure for working with it, as described in the previous section. With the door trim and fittings, do as close as possible to what is described in it.

4) If instead of a metal back card you prefer, for example, laminated plywood or you made your door to order without a back card, and we will offer you the same plywood or a material close to it in functionality, then:

fill her insides in a familiar way;
make in places where sheet metal is bent, corners with the necessary parameters (which will include your plywood) in order to fasten them with self-tapping screws to the outer shaped pipe door leaf;
insert the plywood back card of the door into the pocket formed with the help of the corners and close its perimeter with the same corner using a suitable sealant.

5) Don't forget about the box. When insulating it, remember that the best thermal insulator today is polyurethane foam. If you can fill the inside of the box and the perimeter around it with it, do it.

If you have the opportunity in any way to insulate the box at least a little from the outside, be sure to do it: at least with an overlay through the insulation, at least as close as possible to door leaf warm slope.

6) In all options for insulating entrance doors, remember about the seals of the vestibule. If yours do not fully meet the conditions of windproofness, change them and subsequently regularly monitor their condition.

Heating an entrance metal door using electricity

Finally, we want to offer you one simple, but without performing the procedures described above, not entirely economically justified way of solving the same problem of insulation of the input metal door - electric.

Probably, it is not worth long explaining why, by heating the front door from the inside, we will get rid of condensation and ice on it. Naturally, by moving the dew point from the back of the door to the street, we will drive it inward. And if the materials we proposed there are installed correctly, then everything will be in order, and if not, then the consequences of this are listed in the same article, but above (condensation, wetting of insulation, mold).

How and what to heat up:

By installing a heat curtain or some directional heater;

By laying an infrared electric film for warm skirting boards from the inside;

By placing a self-regulating thermal cable for water supply inside the box or laying around it.

The main nuances of the device for heating the entrance metal door using a cable underfloor heating are indicated in the video below.

Some advise using a 12-volt version of it, but this is hardly advisable, given that such a cable is laid inside a water pipe, and installing a power step-down transformer is clearly not the best option.

The effect will be the same in all cases. Also, all of the above can be installed through the thermostat, which will allow, once setting the required temperature, at which condensation will not occur, to forget about this problem forever. Anyway, as long as the house has electricity.

Dear readers, if you have any questions, ask them using the form below. We will be glad to communicate with you;)

Across open doors and other openings in winter a lot of cold penetrates into the room. With a large passage of people, for example, in a store, warehouse or enterprise, serious heat loss is observed. In addition, unfavorable conditions are created for the people inside. A heat curtain can solve the problem simply and effectively.

Climatic equipment, especially electrical type, is very popular because it is easy to install and use, efficient and reliable. If you need an electric heat curtain, in kW power is measured - one of the key selection factors. It indicates the performance of the device and its capabilities.

Features and differences of electric thermal curtains

Electric curtains prevent cold air from entering the premises by supplying a continuous heated air stream. Electric heaters and heating elements are responsible for heating, they can be of different power. In addition, the devices can be two-phase and three-phase. Domestic curtains are connected to two phases. They are for doorways no more than 2-2.5 m high and 1 m wide. Three-phase industrial equipment is installed on large openings.

By the type of attachment, they can be of the following types:

vertical;
horizontal;
built-in (mounted in dropped ceilings, in window frames, wall panels and so on).

Most models are equipped with automation. It regulates their work and makes it safe to use. It independently maintains the air flow temperature at necessary level, turns off the equipment when overheating, and so on.

Features of the choice of electric thermal curtains

When choosing equipment to provide an air barrier in the opening, several important parameters should be considered:

Device power. Power determines performance. For instance, thermal curtain 3 kW well suited for home, office or small shop, but for industrial facilities more powerful models should be selected.
Opening dimensions. In some cases, installing one curtain does not completely solve the problem, therefore two or more devices are required.
Climatic conditions... It is necessary to take into account at least the approximate temperature of the outside air and the speed of its movement.
Room area. A large room requires a heat curtain 9 kW and more, and for small rooms less powerful devices can also be purchased.

If you find it difficult to find the right model, contact our specialists for help. When calculating, we will take into account all the necessary parameters and select the optimal device.
