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

Prevention of heat loss through doorway is relevant in rooms where the front doors are often opened. For this purpose, a thermal curtain is used, which is a modern and functional equipment. Right choice such devices requires taking into account many criteria, 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 thermal curtain, which is an elongated metal case with an internal fan, a heating device, a nozzle and other elements. A complex of such parts is connected into a whole system inside the case, which provides operational heating of the air, the flow of which enters above the front door, as if cutting off the cold from the outside.

Inside the case, 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 driven by a fan, and when heated, it is brought out through the 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 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 thermal curtains. A heater is used as a heating element in such devices, and a connection to 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 places.

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

Horizontal placement of the thermal curtain is in demand and convenient

If horizontal airflow is required, then the thermal 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 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 thermal curtain prevents the cold from entering the room from the outside, and in the second case, 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 curtain models 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 power or performance, indicating how much air the device can heat in a certain period. The installation height of the air curtain influences the determination of the optimal 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 per 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, which ensures complete coverage of the entire opening with an air shroud.

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

The type of heating element matters if durable 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.

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

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

Functional are devices in which more than three buttons are provided. Such equipment has a timer, adjustment of the angle and speed of the air flow, control of the installed thermostat. The cost of such devices is higher than with the main buttons and without a thermostat.

Modern thermal curtain can be easily adjusted using buttons

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

price. 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 manufacturing climate 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 desired characteristics which will be effective in operation. Having decided on them, they select suitable model climate equipment.

How to install a thermal curtain

The 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 air curtain require connection to the water supply system and the exact location of the pipes

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

The main stages of work are expressed as follows:

Video: an overview of the design of the thermal curtain

Proper use of the equipment

Climatic equipment quite unpretentious in operation, but manufacturers recommend following certain rules for using devices, which is especially important for electric models. Key Tips:

It is forbidden to use the air curtain in rooms with explosive, biologically active and dusty environments or environments that cause corrosion of materials. Do not use the thermal curtain in rooms with a relative humidity of more than 80%. Prolonged operation of the air curtain in the absence of personnel is prohibited. Do not operate the device without grounding. Do not turn on the device with the cover removed;
devices are designed for operation in areas with a temperate and cold climate, in rooms with an ambient temperature from -10 ° C to +40 ° C and a relative humidity of no more than 80% (at a temperature of +25 ° C in conditions that exclude contact with it drops and splashes, as well as atmospheric precipitation);
connection of the device to the mains must be made by means of a power cord equipped with a plug to ensure guaranteed disconnection of the device from the power source. In the case of connection directly to fixed wiring, a disconnector must be provided in it to ensure that the device is disconnected from the mains. Take special care when transporting the instrument. It is not allowed to fall;
it is strictly forbidden to eliminate leaks of the coolant on the fan heater, the water line of which is under pressure. The supply of the device must be only through a shut-off valve.

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

Thermal curtain - what is it

In fact, this is a cold air cut-off for entrance doors, which works on the principle of a heat fan. It protects the room from drafts, and its inhabitants from cold and disease. The installation can be vertical and horizontal, but the functions are identical - to ensure the supply of heat, to exclude the penetration of cold air from the street. The thermal curtain is powered by the mains, the voltage is 220 Volts. If on front door to hang such a unit, there will definitely not be dissatisfied with such an innovation.

How a thermal curtain works

For climate control in a room of any footage, a progressive device of a thermal curtain is specially designed. 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, jet outlet nozzles. In addition, a sensor and other devices can be mounted to quickly heat the air, control the air temperature in the doorway.

Electrical

There are several types of curtains, which differ in the principle of operation and installation method. In the first case, an electric thermal curtain that operates on 220 V 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 warm air is distributed by means of a classical fan. For home use, this is an excellent option, since the thermal curtain has a discreet design and compact dimensions.

Water

Compared to the previous proposal, this a budget option, which in the process of use has a number of advantages. Among those dimensions, low noise level during operation, overheating protection system, economical power consumption, affordable 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 resistance to sudden changes in ambient temperature, has a long service life, 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, this is very important so as 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 running, because they are discreetly fixed above the door or window opening across the entire width. Vertical thermal curtains provide a stable barrier, and a sufficient level of heat is maintained in the room for a long time. Wall mounting requires certain skills, so it is especially convenient and simple not horizontal, but floor installation. Such mobile designs are becoming more popular every year.

Electrical horizontal

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

Embedded

When buying a thermal curtain on the front door, it is appropriate to install it behind a false ceiling or install it in the opening of doors and windows. Modern models are equipped with additional features to prevent condensation. Universal thermal curtains are considered a full-fledged heating element, suitable for home use and installation in office premises. You can choose a suitable design on the Internet or seek the help of a consultant in a specialized store. Thermal curtains above the door are inexpensive, ordering and buying in the online store is cheaper.

Air curtain performance

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

How to choose a thermal curtain

Questions about how to insulate iron door in a private house, on the Internet, there are much more than intelligible answers to them. Or rather, there are even many answers, but they are basically such that they give rise to even more questions, because most of them do not solve the problem at the root due to fundamental errors in the approaches.

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

The picture depicted in these photographs is seen quite often. Or 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 thorough factory insulation, are not without 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 box are precisely those bridges of cold that, with a slight frost, will provide you with a large amount of condensate, and with a thorough frost, which sometimes happen in Mother Russia, will lead to the formation of ice. Why is this happening?

Reasons for the freezing of the iron door in a private house

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

If the temperature outside drops further (or the temperature inside 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 paved the inside of 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 inner surface doors, but on the inner surface of the outer sheet of its canvas. What will happen to her in this case? Definitely, it will be absorbed by the cotton wool until completely saturated, which will lead to:

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

To the quite reasonable question that arises for many about why such doors are produced, there is one reasonable answer: for installation in apartment buildings, the temperature in 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 entrance metal doors are ten times more than the owners of private houses who want to do the same.

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

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

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

In such doors, first of all, they fight against condensate formation in two ways:

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

For this:

They make inserts into the boxes, ends and stiffeners of the door from hard plastic, which interrupts the heat transfer through the metal;

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

Install electric heating of the box, and sometimes the door leaf.

Sometimes the manufacturer uses such methods in one door structure. The acquisition of just such a door will be the first option for solving your problem. True, and we would advise to add something to it.

Namely:

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

Such a refinement 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, preferring a cheaper option.

For this:

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

2) Remove the so-called factory insulation and choose the option of subsequent closing of 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 with some corner, do it as shown in the picture above. Please note that the rail, screwed with screws to the supporting 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 completed mounting foam. Also, a bar protruding literally 1 - 1.5 mm above the profile pipe will break the direct contact of metal with metal, 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, proceed as close as possible to that 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 terms of functionality, then:

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

5) Don't forget the box. When insulating it, remember that the best heat 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 at least slightly insulate the box 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 variants of insulation of entrance doors, it is necessary to remember about the seals of the porch. If yours do not quite meet the windproof conditions, change them and subsequently regularly monitor their condition.

Heating the front metal door with electricity

Finally, we want to offer you one simple, but without performing the procedures described above, not quite economically justified way to solve the same problem of insulating the entrance metal door- electric.

Probably, it is not worth explaining for a long time why, by heating the front door from the inside, we will get rid of condensate and ice on it. Naturally, by moving the dew point from the back of the door to the street, we will drive it inside. And if the materials we proposed 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 the insulation, mold).

How and what to heat up:

By installing a thermal curtain or some kind of directional heater;

Laying an infrared electric film for warm baseboards along the inside of the box;

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

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 set through a thermostat, which will allow you to set the required temperature once, at which condensation will not occur, and forget about this problem forever. At least as long as there is electricity in the house.

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

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

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

Features and differences of electric thermal curtains

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

According to the type of attachment, they can be of the following types:

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

Most models are equipped with automation. It regulates their work and makes their use safe. Independently maintains the temperature of the air flow at required 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. Eg, 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 air curtain does not completely solve the problem, so two or more devices are required.
Climatic conditions. It is necessary to take into account at least the approximate temperature of the air from the outside and the speed of its movement.
Room area. For a large room, a thermal curtain is required 9 kW and more, and for small rooms you can buy less powerful devices.

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