Prevention of heat loss through the 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. The correct choice of 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 heat curtain, which is an elongated 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 provides operational heating of the air, the flow of which enters above the entrance door, as if cutting off the cold outside.

Inside the case, the air 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 discharged outside through 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 and public premises.

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 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 electric-type models 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.

The 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 with a width of 1 m and 2 m in height, 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 spaces, productive and high-quality air 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 a lot of energy. 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 switch-on, 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 heat curtain, such features as:

• price. Inexpensive and simple models are 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 desired characteristics, which will be effective in operation. Having decided on them, they select a suitable model of 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 a connection to hot water supply and therefore are not in demand, and their installation is carried out by professional craftsmen.

Water models of a heat curtain require a connection to the water supply system and an accurate location of pipes

Installation will require anchor bolts, brackets, drill, building level and 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 is quite unpretentious in operation, but manufacturers recommend observing 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 a fan heater, the water line of which is under pressure. The device must be connected only through a shut-off valve.

The purpose of the heat curtain is to prevent the penetration of cold air currents inside the room and keep warm. With the help of the curtain, the possibility of drafts is eliminated, moreover, with the doors open.

The air curtain should not be compared with a heat gun, its purpose is to heat the space: the heat curtain on the door does not heat the air. Installing such a protection saves heating costs by preventing heat leakage.

A little about thermal equipment

We analyze all the pros and cons of thermal equipment:

• Savings in heating costs;
• Keeps cool during the summer season;
• Prevents the appearance of drafts;
• Protects the room from dust, insects and dirt.

The disadvantages of the system include a high noise effect during operation - from 50 dB. The noise from the operation of the device can be compared to a washing machine. Moreover, all models have a noise effect, regardless of the manufacturer.

Structure and principle of operation

Air-heating curtains are designed according to the principle of fans that blow air into the room, but with a higher rotation speed. This fan creates a dense air gap in the doorway, which prevents mixing of air currents of different temperatures.

Types of air curtains

1. By type of installation;
2. By the type of coolant.

According to the type of installation, models with horizontal and vertical fastening, as well as hidden ones, are distinguished. Vertical curtains are installed at the top of the doorway across the entire width. Horizontal models are mounted on the side of the doors.

Hidden curtains are installed in door openings or on suspended ceilings. For specialized premises, products are manufactured with additional functions, for example, curtains with protection against water drops in car washes.

The heat carrier of these structures can be electric heating coils, heating elements and hot water from the heating system. Electrical devices are easy to install and maintain. Devices connected to water heating can be installed when building a house or during a major overhaul. The price of water curtains significantly exceeds electrical counterparts, however, it quickly pays off during operation.

We watch the video, the principle of operation:

The advantages of spiral heaters include instant warm-up, reduced noise effect and uniform distribution of warm air over the area of ​​the air gap. Prices for thermal curtains for doors fluctuate around 8,000 rubles.

The disadvantage is the burning of oxygen in the room. Heating elements do not have contact with air, due to the placement of the heating element in a heat-insulating material. Heating elements made of ceramics are considered the most preferred and economical ones (their price starts from 11,100 rubles).

Model overview

How to make the right choice

Here are some criteria for choosing heating equipment:

1. Curtain length / width;
2. Turbine device;
3. Control type;
4. Heating element type;
5. Additional options.

The correct length of the air curtain determines the efficiency of the structure: it must cover at least 3/4 of the opening length.

When installing horizontally, the width of the door opening must be taken into account: the length of the blowing element must exceed the door width by 10 cm. If the doorway is very large, it is advisable to install several curtains that provide a good protective layer. Otherwise, the installation of the system will not bring results.

The turbine device determines the speed of movement of the air streams formed by this apparatus. For example, for a conventional door 1 / 2.5 m, a curtain with a capacity of 900 m3 / h (5 kW) is required. If the rate of flow formation is insufficient, the efficiency of the device will be significantly reduced: there will be loopholes for the penetration of cold. In this case, a vestibule is installed in the house, which will partially retard cold streams from the street.

Watching the video, equipment selection criteria:

The type of heating element must be selected based on the conditions of the protected room. Coil heaters tend to burn oxygen, so they are not desirable at home. Heating elements are more expensive, but the design provides for the protection of oxygen from burnout. Heating elements are located inside a metal tube, the inner space of which is filled with heat-conducting quartz sand. Heating by connecting to a heating network saves energy costs, however, such structures are difficult to install and are installed in industrial facilities.

Does the power of the heating element affect the efficiency of the air curtain? No, it doesn't. The performance of the device is determined by the rate of formation of air currents, and not by heating the air. If you have a vestibule, you can choose the device without heating function or with minimal heating: this will save money. Additional options include a remote control and a timer. This creates additional usability.

Outcome

When choosing the required device, determine the correspondence of the dimensions of the doorway to the selected model. In case of discrepancy, give preference to horizontal devices. It is not recommended to save money when buying a protective curtain and purchase the cheapest device with air circulation of 300 m3 / h: such devices are designed for stall windows.

There are much more questions on the Internet about how to insulate an iron door in a private house 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 has to be 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 thorough 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 exactly 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. When the conditions are stable (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 what insulation material you put inside the door. And at the plant 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 canvas. What will happen to her in this case? Definitely, it will be absorbed by a cotton wool insulation until it is completely saturated, 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 center of corrosion 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 reasonable answer: for installation in apartment buildings, the temperature at the entrances of which (if there is heating in the house) does not drop 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 look in the vast steel door market for one that is made for these situations. In fact, there are not so many of them. Maybe even more than the 1% allotted 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;

The structural elements of the door interrupting the cold bridges are displaced (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:

1. If your door has a wood trim (1) on the outside, place a thin foamed polyethylene membrane underneath, at least the one used for laminate flooring.
2. A dense plastic film installed under the decorative cover of the door handle and locks (10, 14), which you carefully trim along the contour after fixing them, will effectively reduce the possibility of moisture condensation on the inside of the fittings.
3. If any 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 card of the door. It is better if it is applied without gaps, which will prevent moisture condensation between the metal sheet and the insulation. The ideal option is when the dew point is in the array of this insulation. This is not cotton wool for you - physical water cannot form inside.
4. 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.

This 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 site 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 the wooden rail must be filled with 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 required parameters (which will include your plywood) in order to fasten them with self-tapping screws to the outer profile pipe of the 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 with a warm slope as close as possible to the door leaf.

6) In all variants of the insulation of the entrance doors, it is necessary to remember about the seals of the vestibule. If yours do not fully meet the conditions of impermeability, 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 insulating an entrance metal door - an electric one.

Probably, it is not worth explaining for a long time 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 the insulation, mold).

How and with what to warm up:

By installing a heat curtain or some kind of 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 there is electricity in the house.

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

The whole complex may turn out to be impractical if the heat leaves the house through. A special device helps to correct the situation: a heat curtain on the front door. We offer you to get acquainted with the principle of operation, varieties and features of the operation of such equipment.

Heat curtain - what is it

Looking at the existing species, a thermal curtain can be seen. What it is can be understood by the functional features of this device. It is installed directly above and prevents the penetration of cold air from the outside. At the same time, a heat curtain is one that allows you to heat the air in the room.

Attention! Installation of a heat curtain allows you to reduce heating costs by a third.

Thermal curtain on the front door: principle of operation and main technical characteristics

In terms of its design, the thermal curtain is close to that of a household one with a characteristic elongated rectangular shape. The holes in the top and bottom of the case are used to create airflow. Air is drawn in through the holes in the top. The inside fan provides a top-down air flow. A heat exchanger near the unit heats up the flow of air that flows out through the openings in the lower part of the unit.

When selecting a thermal curtain, one should be guided by the technical characteristics, which include:

• device performance, showing how much cold air can be heated with it;
• fastening type;
• heat curtain power.

Varieties of thermal curtains for the home by location and type of installation

When choosing a thermal curtain for a house, you should be aware that such devices can be located in different ways relative to the opening and have a different type of installation. By location, the device can be:

• horizontal... The most common classic version. They are mounted directly above or;

• vertical. Such a performance is relevant if it is impossible or irrational to install a horizontal model. Vertical products can be located only on one side of the entrance door or on both sides;

• universal that allow horizontal and vertical mounting.

According to the type of installation, the division is made into models that are mounted directly on the wall, and units that are built into the ceiling or wall. The latter option is relevant when arranging a room, the design of which is subject to increased requirements.

Types of household heat curtains by the presence and type of heat exchanger

The design of household heat curtains may differ slightly. Manufacturers offer devices equipped with heat exchangers of various types, as well as without them. We offer you to get acquainted with the existing species and their distinctive features.

Electric heat exchanger for air-heating curtain

The most efficient models. Easy to install and maintain. Installation is permissible not only above, but also in any other place. Allows you to smoothly adjust the temperature of the outgoing air.

Most modern air-thermal curtains are equipped with tubular electric heaters (TENs). Cheaper analogs are semiconductor heaters (RTS). They have the function of self-regulation of energy consumption and temperature, which allows you to optimize energy costs.

Attention! The thermal curtain on the front door 220 V can become the best option for a private house and public building.

Thermal water curtain on the front door

Any electrical heat exchanger has a high operating cost. From this point of view, a water thermal curtain on the front door is preferable, since it can be connected directly to. Economy of maintenance and absence of harmful influence on the environment are important advantages of devices of this type. However, in a number of cases, their installation is refused due to their large size, the complexity of installation work and increased requirements for the state. If the quality of the heat carrier used is low, there is a risk of getting inside the small tubular structure of the device, which can cause the device to fail.

"The installation of a water heat curtain should be carried out in conjunction with a filter, or initially choose a model equipped with this element.

"

Models without heat exchanger

Such devices become relevant in a situation where it is not necessary to produce additional air heating. The RV series thermal curtain circuitry allows you to protect the interior from street dust, dirt, insects, preventing leakage outside the house. Such devices are most often mounted on the territory of industrial enterprises, acting as an element of zoning a spacious room or protecting the freezer from the ingress of outside warm air. Other applications are also possible.

How to choose a heat curtain by power

In order for the device to be installed to cope with the task assigned to it, its power must be suitable. Thermal devices are divided into the following series:

The first series has a limited scope. With its help, you can protect only a relatively small opening, for example, a service window at a cash desk or a street kiosk. For domestic purposes, they are practically not used. They are distinguished by low productivity. They are used for openings up to 1.5 m high and up to 0.8 m wide.

The power of the RM series air curtain is sufficient for installation above standard doorways with a height of up to 3.5 m. They can be mounted above the entrance door. This series is most popular with a wide range of consumers. They are often equipped with remote controls or special external units that simplify the control process.

The RT series is the most powerful. With its help, you can protect an opening up to 7 m high. This is a suitable option installed in premises for various purposes, for example, warehouse or production.

How to install a thermal curtain

The installation of the air curtain must be carried out in accordance with the manufacturer's instructions. The work is carried out in the following sequence:

• the place of installation of the thermal curtain is selected, taking into account its design features;
• the base is being marked;
• brackets are attached;
• equipment is mounted;
• the control unit is mounted;
• connection to the power supply system and protective elements;
• system health check.

Features of connecting air curtains

Typically, the scope of delivery includes a flexible cable and a plug with. With a fixed connection, the heat curtain is connected via a central switch. A gap of up to 3 mm must be left. The work can only be done by a professional.

Attention! Use a special type of wire for the connection.

Heating curtains maintenance rules

In order to prolong the life of the equipment, the manufacturer's recommendations for the maintenance of the air curtains should be adhered to. Every month, a visual inspection of the device should be carried out, the quality of the fastening should be checked, the absence of visible defects, the operating current and voltage should be tested. The device needs monthly cleaning of the housing, air filters, entrance louvers from accumulated dirt and dust.

On a quarterly basis, with the help of specialists, the quality of threaded connections is monitored, contacts are cleaned, fuses and tips are checked. If necessary, damaged elements are replaced with new ones. The condition of the fan is monitored.

The working hours are changed every six months due to the change of season. Pneumatic cleaning of the main components, including the heat exchanger, is carried out. Once a year, the heat exchanger is cleaned with a special chemical composition. The condition of the fan motor bearings is monitored.

Nuances of repairing heat curtains

Most often, it is rather difficult to establish the cause of the failure on your own. Diagnosis may require the help of a specialist. Often, equipment breakdown is caused by non-compliance with the manufacturer's recommendations on the operating mode of the thermal barrier, which causes it to overheat. As a consequence, it may be necessary to replace the heating element, switch or electrical contacts.

Attention! Repair of air curtains can not always be carried out in the places of their installation.

Repairs can be carried out as follows:

• the presence of electricity is checked. If the network is stable, the heat curtain should be disconnected from the network;
• fuses and contacts are checked. Defective elements are replaced with new ones;
• the operability of the switch and the quality of the contacts in the electrical circuit are checked. Failure of the switch may be indicated by the fact that after moving it to the "Heating" position, the air is not heated.
