Choosing a heating system for a private house - important question, the right decision which provides comfortable accommodation the owner of the house and his family members. In addition, the optimally selected option saves a certain amount of money and ensures the reliability of operation required in frosty winters. Consider one of the underutilized, but quite effective types of home heating - air heating.

Expert opinion

Fedorov Maxim Olegovich

Air heating of a private house is carried out by supplying warm air to the premises. It heats up all interior items, furniture, walls and floors of the house.

A comfortable and cozy environment for residents is created. Unlike common water and electric kinds heating, air heating has a faster action, less inertia and can be regulated much more accurately and efficiently... In addition, such systems are often combined with ventilation systems, allowing you to filter the circulating air and remove dust particles and other unnecessary suspended matter from it.

It is easier and less costly to heat the air than to heat the coolant in a boiler, using fuel or electricity, so the efficiency and economy of air heating can well compete with any other method. Such systems are greatly underestimated and have great prospects.

Device

An air heating system needs the following components:

• heat exchanger in which the air is directly heated

• a control device that allows you to adjust the operating modes and temperature in the house

It is noteworthy that the air heating of a private house does not create an excessive back pressure, causing slamming doors or difficulty opening windows. The pressure drops are quite small and invisible, they do not cause any unpleasant sensations or difficulties.

Advantages and disadvantages

The air heating system of a private house has a number of advantages:

• high efficiency and speed of heating

• profitability... Air heating costs are much lower than alternative methods

• The efficiency of this method is the highest - up to 93%

• the transfer of heat energy is carried out directly, and not through intermediate devices (pipes, radiators, etc.)

• control of the system is quite easy and allows you to organize in each room its own temperature regime

• from a structural point of view, the installation of equipment is an easy task, since there is no high pressure and there is no need for an exceptional tightness of the air ducts. If a hole appears in one air duct, no accidents occur, no one suffers from this.

• the equipment has a rather long service life - according to experts, a 20-year period of operation for the system is quite affordable

• system cost is low

• opportunity self-assembly the highest of all available options

• the need for a high-quality calculation of the system. All errors will cause insufficient heating, which will manifest itself at the most unfortunate time - in winter frosts, so the accuracy of the calculation must be appropriate

• There is a need to maintain and clean the air ducts from soot, dust and condensation. Accumulations of extraneous layers reduce traction and disrupt the heating of the premises

Kinds

There are two main air heating systems:

• with natural circulation

• forced circulation

Natural circulation

Natural circulation systems work on the principle of raising hot air up... Rising, it displaces the colder layers, gradually warming up the entire room. To ensure the functioning of this method, it is necessary to have a heater at the lowest point of the house (in the basement), which forms a kind of pillow of heated air that rises up and enters the premises. Cold masses come to replace the rising hot masses and everything is repeated again.

This technique is good in that it does not create multiple recirculation of air that accumulates dust, saturated with carbon dioxide and loses its quality.

Forced circulation

Forced circulation enables more precise, targeted regulation of the flow entering the premises. The movement of air masses is provided by a fan, which stabilizes the movement of the hot jet, creates a constant pressure and air flow. At the same time, the saturation of such a system with equipment is much higher, in addition, the operation of the fan depends on the availability of electricity, and in case of interruptions that are possible in private houses, the heating of the premises stops. In addition, the fans, although they have a large resource, service life, sometimes fail, which forces the owner of the house to provide an alternative type of heating in case of malfunction of the main system.

There are different types of heat generators, according to the name of which heating systems are sometimes classified, emitting gas, solar or electric air heating. This classification seems to be erroneous, since the heating system itself or the principle of heating does not change with a change in the type of heat source.

How is the calculation done?

The calculation of air heating includes several steps:

• determination of heat loss in premises

• by the amount of losses is the power of the heat generator

• the amount of air required to supply the premises

• section of air ducts

Air heating design is not an easy task. To solve it, it is necessary to find out a number of factors, the independent determination of which may be difficult. RSV specialists can make a preliminary for you free of charge premises based on GREERS equipment.

Without being a specialist, it is simply impossible to correctly calculate the air heating of a house. You need to know the calculation methodology, which has many options, and most importantly, you need to have the appropriate experience in order to correctly calculate all the losses and the required power. For this the best option will... Only he, after a thorough examination of the house, the material of the walls, floors, comparison of volumes, other parameters of the premises, will be able to accurately make the necessary calculations.

On one's own

Alternatively, you can use an online calculator. There are many of them on the network on specialized resources, where it is enough to substitute your data for all the necessary parameters to get the desired result. This method of calculation is frankly weak., cannot be compared with the calculations of a specialist, since not everyone knows some important parameters of the house. Nevertheless, the method exists and is actively used. For greater accuracy, confidence in the quality of the calculations, you should duplicate them several times on other resources in order to choose a certain average value from several options.

Equipment selection criteria

Heat generator selection

First of all, you should decide on the choice of a heat generator. Its power is known from the calculation, but what type of it is is determined by the capabilities of the owner of the house, the availability of fuel or resources. In the complete absence of any resource receipts, either a solid fuel boiler or a gas boiler operating on imported gas (in cylinders) is selected.

The presence of electricity, connection to the hot water supply system or from the gas main can change the choice to some other. Usually, the main selection criterion in the presence of several options is the highest efficiency of one or another type of heat generator, its reliability, and simplicity of design. There are boiler designs that can operate on different types fuel. To switch from one type to another, you only need to change the burner, which is very practical in a private house.

Equipment

The choice of a heat generator determines the selection of the rest of the equipment corresponding to it in terms of power, performance or throughput. The type of boiler determines the presence, composition of additional equipment for supplying or storing fuel, adjusting the combustion mode. Here, the most successful design of the heat exchanger is selected, corresponding to the parameters of the heater. Most designs of heat exchangers are based on the principle of action - washing or passing a stream of cold air through closely spaced heated elements.

Air ducts

The choice of air ducts is based on their capacity. For a private house, flexible channels are good, capable of being installed in any conditions, providing the possibility of replacement if necessary. The channel system usually ends.

Control or selection of a certain mode can be done manually or using an automatic control device.

DIY installation procedure

Installation of an air heating system in a private house consists in installing and connecting a heater, a heat exchanger, a system of channels that transport hot air to the premises. To carry out the work, the most optimal time will be the stage of building a house, when all the necessary technological holes can be made without destroying the decoration or decor of the walls and ceilings.

• The installation of a boiler with a heat exchanger is carried out in a special room equipped according to the operating conditions of the equipment.

Important! A test run of the system is carried out at the minimum heating mode, which gradually increases to the desired value.

Useful video

The working scheme of air heating includes a minimum set of equipment:

1. heat source (heat generator);
2. air ducts that deliver heat to heated areas.

Examples of homemade air heating are presented in detail on the Internet with photos and diagrams, but interest in such systems does not wane. The advantages of air heating include:

• high efficiency reaching 93%;
• direct heat transfer to heated areas without pipes, heating radiators, etc.
• the ability to create a room microclimate by combining heating with a climate system;
• power and low inertia of air heating, which allows you to quickly warm up the house to the required temperatures.

Here are several ways to arrange air heating of a private house on their own, we note the pros and cons of each of the methods.

How to make air heating of a private house from the sun

Advantages solar heating obvious - the homeowner invests only in the purchase of equipment, and the heat source itself does not cost anything. Solar power plants pay off in about three years, and their service life is ten times longer (up to 30 years).

There are two types of solar heating: solar powered and.

Benefits of solar heating:

• absolute environmental safety;
• ease of use;
• continuous development of production technology and reduction in the cost of equipment.

Among the shortcomings, we note:

• low productivity of the station on cloudy days;
• the still high cost of equipment and installation;
• the need for accurate calculation and correct placement of equipment for maximum productivity.

Solar powered installations

The principle of operation of such installations is based on the formation of direct current by sunlight when it hits special semiconductors. The converter converts DC to AC. The voltage that appears in the solar panels is transferred to the heating system. Energy can also be stored in a battery and then used in cloudy weather.

Solar panels are technically challenging and require knowledge and skills to manufacture them. In addition, such equipment is usually used to. This type of heating is used wherever available electric heating- or . If the capacity of the installation is sufficient, then you can provide the house with hot water.

The efficiency of batteries depends mainly on the amount of solar energy. In middle and northern latitudes, where the sun is not enough, it is possible to recommend the use of combined installations, in which solar panels will play a supporting role.

Installations on solar collectors

The principle of operation of such installations is also based on the collection and transformation of the energy of the Sun, only the transformation takes place not into electrical, but into thermal energy. The heat carrier in the collector is heated by the sun's rays and gives off its heat to the room. The performance of such an installation also depends on the amount of sunlight.

Heating installations are distinguished by the type of heat carrier:

• water and antifreeze;
• air.

The order of the solar collector device:

1. Insulate the wall on the south side of the house with polystyrene foam and paint it with black paint.
2. Sew wooden slats on top.
3. From below, through the wall of the house and insulation from the edges, punch 2 convection holes for cold air, from above 1 for hot air. Hole diameter 20 cm.
4. Sew on the slats with corrugated board, which is covered from above with black plastic wrap (preferably glass).

The principle of operation of the collector is very simple: the circulation of cold air from the house occurs through the lower openings, the heated air enters the house through the upper convection opening.

In November, at noon at a temperature of 9 degrees on a sunny day, the air supplied to the house is heated by the collector to 46 degrees.

Scheme of solar air heating of a private house

How to make air heating with your own hands from a stove

When calculating air heating, it is assumed that 1 kW of heater power can heat 10 square meters of a well-insulated room. Fireplace inserts with a capacity of 10 kW are respectively capable of heating a house with an area of ​​100 sq. M.

Natural convection systems

An air heating system from a stove (fireplace) implies the spread of heat to other rooms of the house by streams of heated air. For this, flexible thermal insulation channels are usually used, coming from the fireplace.

The movement of streams of heated air can be natural and forced. If the air flow is directed vertically, then natural movement will be ensured, if hot air must be supplied over long distances horizontally, then forced supply is needed. The project of air heating of a house from a fireplace should make the most of the possibilities of natural convection, which requires large air ducts.

Refractory materials and minimum aerodynamic resistance are the main requirements for air ducts. The length of the duct from the fireplace to the room should be no more than 3 m. There should be no narrowing or bending on it. The natural air movement heating system can heat no more than 4 rooms. During installation, special attention is paid to the insulation of sections of air ducts next to the combustible materials of the building.

Forced convection systems

The principle consists in collecting air in a convection chamber and forcing it from there into different rooms of the house by one or several duct-type fans. The distance of heat supply is no more than 10 m. Flexible ventilation ducts or air ducts of small diameters are used.

How to make air heating based on Buleryan

The buleryan stove was designed for Canadian lumberjacks. Due to its unique characteristics, it spread very quickly, and today Buleryan is used for heating housing, production, garages, greenhouses and other facilities.

The furnace is based on the principle of gas generation, i.e. "Smoldering" combustion mode with oxygen deficiency. Cold air enters the furnace openings from below, and air heated to 60 - 80 degrees comes out of the pipes of the upper part of the furnace. The combustion mode in such a furnace is complete, i.e. with the afterburning of combustible gases in the furnace with air supply. The stove is very economical - one firewood load is enough for 6 - 8 hours.

Do-it-yourself air heating of a private house from Buleryan is arranged by connecting air ducts to the nozzles of the furnace and distributing heat through air ducts throughout the house. Air ducts can be made of corrugated aluminum or sheet metal. Air ducts transport hot air only from the stove, there is no return flow, which reduces the heating efficiency.

On the photo is the buleryan stove. Manufactured Canada

How to make air heating from cans

Do-it-yourself air heating of a private house from cans - an example self-made effective heating system from scrap materials.

1. Manufacturing of air streams

1. You will need 196 soda cans, which you will need to wash and make holes on the top and bottom.
2. Fasten the cans together with silicone, making a tube of 14 cans. A total of 14 columns of 14 cans. These are the channels through which it will enter the house warm air.

2. Making a box for a collector

• For the box, you will need plywood and a board, PVA glue, high-temperature silicone, mineral wool for insulation.
• The board must be cut to size, the joints must be nailed and glued.
• The finished dry box must be insulated with mineral wool.
• In the upper wall, you need to make 14 holes for the size of the can. These are places where warm air is collected.

3. Assembling the manifold

It is better to see the assembly of the collector and its preparation for work - the whole process is shown in detail in the video at the end.

The collector is capable of heating air up to 70 - 80 ° C. The use of such a collector can significantly save the consumption of natural gas and electricity for heating.

Something like this looks like a collector from aluminum cans

conclusions

The variety of air heating systems allows you to choose the most convenient and most effective scheme for each specific case. The popularity of air heating in the USA and the EU is not accidental - the efficiency of such heating installations is about 90%, while that of the hot water heating system, which is popular in Russia, is no more than 60%. The future belongs to inexpensive and efficient air heating methods, so now you need to select installations and use them to heat your homes.

Industrial air heating systems widely used for heating production halls, warehouses, construction sites, various commercial facilities, in agro-industrial enterprises and agriculture.
The air supplied to the premises has a temperature of +40 - 50 ° C and is distributed through a system of air ducts with a variable cross-section.

Industrial air heating cost-effective, it can be combined with a ventilation system, which significantly reduces their total cost.

But due to the low specific heat capacity of air and high thermal loads, the use of air for heating purposes is effective when supplying large volumes of warm air, which, in turn, leads to huge oversized air ducts and powerful fans that require significant energy consumption for air transportation.

However, at present, industrial air heating is most widely used in modern enterprises and facilities.

Industrial air heating equipment

Air heating in the supply ventilation unit.

The air handling unit has a unit, as a rule, with an electric heater or a water heat exchanger.
The air supplied to the premises, passing through this block, heats up and is distributed through the air ducts, ventilation and heating of the premises occurs.

Heating air in a special installation (heat generator, air heater, etc.)

Heat generators installed indoors or outdoors, their power is calculated based on the total heat losses of the object, which must be compensated for by supplying warm air. Air distribution is also carried out through the air ducts.
The efficiency of these installations is very high and can reach 95 - 98%. Air is heated by burning natural gas or liquid fuel with a burner, while high-temperature combustion products passing through a heat exchanger give it their heat, which in turn heats the air supplied to the premises. With this method of heating the air, it is possible to reach the temperature of the air leaving the heat generator up to +90 o C.

Heat generators have a powerful supply fan of high performance, providing a supply of several thousand cubic meters of warm air per hour and therefore, often when designing, they combine air heating and ventilation, thereby reducing the cost of the total cost of systems.

Heat generators or air heaters have a wide range of thermal power - from about 10 to 1000 or more kilowatts of thermal power and a variety of designs that allow them to be installed on the floor, on walls or under the ceiling in rooms, as well as outside, next to a heated room or directly on the roof building.

Basically, heat generators "work" on a system of metal air ducts that distribute air to several rooms at once and over a large area.

Air heating by small, low-power units distributed throughout the room.

Often, for heating large areas and volumes, installations of small power are used - fan heaters.
Fan heaters structurally consist of a fan, heat exchanger or heating element and a control unit.
Hot water is supplied centrally from the boiler room to the premises to each fan heater .

Passing through the heat exchanger fan heater, hot water or another heat carrier transfers part of the heat to the air, which is blown through the heat exchanger by a fan and through a guide grill or louvers directly into the air environment of the room.

This method of heating premises is convenient when it is necessary to heat large areas at relatively low heights of industrial or warehouse premises.

At the same time, there is no need to install a cumbersome network of supply air ducts, although you will have to lay pipelines to each fan heater to ensure the supply of coolant (water or antifreeze).

When building or arranging your own home, it is very important to choose the optimal suitable system heating. Take a closer look at such an option as air heating.

Air heating at home is a thermoregulation system in which air heated (or cooled) to the required temperature is supplied directly to the interior of the house. This system has a number of advantages over traditional radiator and stove heating systems.

Air heating advantage

Firstly, the heating zones of the house are not localized around stoves and radiators, there are no sudden changes in temperature. In a house equipped with air heating, you will not see fogged-up glass, drips of moisture on the walls and swollen wallpaper - a consequence of condensation of water from the air caused by temperature extremes. Due to the uniformity of air heating, air heating is excellent for rooms with large internal volumes - halls, workshops, warehouses, etc.

Secondly, air heating does not require a complex coolant circulation system. With radiator heating, the coolant (heated water or oil) circulates under high pressure on the complex of pipelines and radiators. A hot heat carrier under pressure is an extremely aggressive medium that imposes high requirements on the elements of the heating system in terms of resistance to corrosion, tightness, etc. Slightest damage any of the elements of the system can lead to the penetration of the coolant into the interior of the building, which poses a serious danger to the safety of people and the safety of property. Air heating is free from these disadvantages.

In addition, radiator heating requires special measures to be turned off in winter: not drained frozen coolant will clog pipelines and radiators, which will make the operation of the heating system impossible for a long time. In general, water has the property of "freezing" - expanding when freezing, which can lead to physical destruction of the entire heating system. Air heating, on the other hand, can simply be turned on and off at any time of the year. This property of air heating is irreplaceable, for example, for country cottages, where people come only on weekends in winter, small private hotels that host guests during winter holidays, etc.

An important (and for someone - the most important) factor is the lower unit cost of air heating systems.

Types of air heating

The use of hot air for heating premises has been known to people since ancient, ancient times. During excavations in Pompeii, “preserved” by the ashes of Vesuvius, walls and foundations of buildings were found, the design of which unambiguously indicated the use of “hypocaust” - ancient systems of centralized air heating.

With the fall of Rome, air heating was forgotten in Europe for many centuries, like many other things that made up the legacy of the Empire. The rebirth of centralized heating systems happened in the 14-15th centuries. It is curious that the heating of walls and floors with warm air was used to heat the chambers of the Moscow Kremlin long before such a method of heating was remembered in Western Europe. Surprised foreign ambassadors told their countrymen about a Moscow curiosity, and for some time central air heating in Europe was called ... "Russian heating".

Air heating became widespread in modern times, when the industrial revolution moved large masses of people to cities. It was this type that was the first central heating apartment buildings London - the then industrial capital of the world.

Direct-flow heating system

The basic design of the first air heating systems was quite simple.... In the lower part of the building, usually in the basement, the air was heated by burning wood, charcoal or coal. The heated air rose by gravity through the cavities in the floor and walls, and went outside through special outlet openings on the roof. The air inside the room was heated indirectly - from the floors and walls heated by hot air.

The efficiency of such a system, called direct-flow, was very modest, b O most of the energy was spent on heating to the entire depth of the walls and floor, as well as on "heating the street" - still hot air was thrown out through the outlets... It was impossible to avoid this: it was the temperature difference in the system and outside that created the thrust, thanks to which the air movement was carried out.

Recirculation heating system

The revolution in air heating was made by the use of a new type of fuel - natural gas. Heating the air with cleaner fuel, coupled with the advent of advanced air filters, made it possible to pump heated air directly into the room, thus creating a closed cycle of air circulation in the room.

Air heated by gas or electric heaters, rising through the air ducts, is supplied to the upper part of the building. Giving off heat, the air cools down and, gradually being replaced by new masses of heated air, goes down, again falling into the heater.

Such a recirculation heating scheme is called gravitational, because air circulation is carried out without the use of any special devices, only due to the force of gravity.

If the structure of the building impedes the free circulation of air, a recirculation scheme with forced ventilation is used. In this case, hot air is pumped into the premises and taken into the heater using special fans.

Heating a building with recirculated air is the simplest and cheapest option, ideal for use in non-residential premises, workshops, warehouses. The fact is that repeated blowing of air through the heating system negatively affects its quality. Air heating of a private house or apartment using a recirculation scheme requires additional costs for air humidification and ionization.

Therefore, for heating living quarters, recirculation with a partial inflow of outside air is often used. With this scheme, the "exhaust" air is gradually withdrawn to the outside with its gradual replacement with fresh air.

There are also various combined air-water or air-oil heating schemes, which are mainly used for centralized heating of several buildings. The heat carrier carries energy from the central boiler room to the buildings, where a powerful radiator acts as a heating element of the air heating system.

Air heating - do it yourself

Currently, there are enough companies ready to install a turnkey air heating system, but if you want to carry out air heating at home with your own hands, it is quite feasible.

You need to start by choosing the "heart" of the heating system - a heating element. Most often, gas heat generators are used for heating residential premises. The choice of a specific brand of heat generator is carried out depending on the area of ​​the heated room and fuel consumption. It is recommended to pay attention to heat generators made in Scandinavian countries. Although not cheap, these models are perfectly adapted to the harsh northern realities.

In addition to the heat generator itself, you will need:

• Air ducts are special pipes through which warm air will circulate. Air ducts can be flexible or rigid. If you decide to use a rigid duct, bends ("curved" parts of the ducts at ninety or 45 degrees) will be charmingly useful to you. You will also have to stock up on "tees" in an amount depending on the complexity of the air circulation system. There are various options for materials for the manufacture of air ducts, but the most widely used are galvanized steel air ducts.
• Grilles through which air supply and intake will be carried out.
• Aluminum tape for sealing duct joints. It is better to use reinforced tape.
• Galvanized steel tools and mounting hardware.

It is best if air heating country house planned at the construction stage... Then the air ducts can be laid in the wall in special niches. If the heating system is installed for finished house, air ducts usually hide false ceilings and false walls.

Air heating at home is a promising and profitable option for home improvement, which we recommend that you turn your attention to. In any case, the choice is yours.

Owners of private houses often solve the problems associated with the organization of an autonomous heating system themselves. Air heating is, although not the most popular type, but a rather effective way to maintain optimal temperature regime... The article will focus on how to make air heating.

Heating of premises does not require the installation of radiators and constant Maintenance... The system is quite economical due to the absence of "intermediaries", because the heated air immediately enters the rooms. Installation of additional equipment provides more opportunities for the owners.

For example, by combining a heating system with ventilation, an inflow of fresh air is provided. Modern automation allows you to control the required parameters of the microclimate by programming temperature sensors.

Advantages of an air heating system

Due to a number of advantages of this system, it can compete with traditional types of heating.

• Full autonomy, the beginning and end of the heating season is determined by the owner of the property.
• Automation is turned on only to maintain the optimal temperature, thereby saving resources (gas, electricity, etc.).
• The system can be turned off for an extended period without any consequences.
• Due to the absence of radiators, the installation of the system is easy, and the interior only benefits in such cases.
• Air currents quickly and evenly warm up the room. The efficiency is 90-93%.
• Complete security. There is no risk of leaks, water freezing, and fire hazard.
• It is possible to connect duct equipment that works to maintain a certain level of humidity.

Air heating circuit

Of course, there are no ideal heating systems. You can add a fly in the ointment to a barrel of honey.

• With improper design, there is a possibility of increased noise and imbalance in the heated air supply.
• Air ducts can be quite large diameter, which significantly affects the height of the ceiling.
• When using gas or fuel heaters, in the event of a fire, harmful substances will quickly spread through the highways into the premises.

The principle of operation of air heating

• A fan is mounted under the combustion chamber of the heat generator, which draws in cooled air from the room and directs it to the heat exchanger. After heating, the streams are distributed through the highways to each room. Combustion products leave through the chimney.
• Warm air displaces cold air (the law of physics) down to the air intakes. This creates natural circulation. However, due to drafts from windows or doors, the process is disrupted and a warm air mass accumulates under the ceiling. This is the only negative of the gravitational system.

• If forced ventilation is used, then the distribution of air masses is faster and more even. But the resulting noise in air ducts and diffusers due to aerodynamic properties creates significant discomfort for people in the premises.

Classification of air heating boilers

The circulation is carried out mechanically when a fan is used to force the air, or in a natural way due to the temperature difference. The system can be central, designed for heating large areas, or local, where optimum temperature maintained in rooms with a modest quadrature.

Air exchange happens:

• recirculating, when the cooled air in the room flows back to the heat generator;
• with partial recirculation;
• with air flow from the street.

Heat generators for air heating

Nice addition to the system

• This type of heating provides ample opportunities to improve the quality of the microclimate. So, due to the flow of air from the street, the premises are ventilated. The system is used not only for heating, but also for cooling air masses. It is possible to supplement air heating with a device designed to maintain a certain level of humidity.
• It is possible to reduce the dust content in the air by using filter elements. The selection of equipment depends on the desired degree of cleaning: from standard to sterility. For prevention infectious diseases you can mount an ultraviolet sterilizer and turn it on as needed.

• Such a system allows you to do without radiators, pipes, bulky boilers used in a standard type of heating. This has a positive effect on maintenance, and leaks, corrosion and freezing of the system will bypass you.

Air heating project

It is better to entrust the preparation of the project, as well as the calculation of the elements of the system, to professionals. Here it is necessary to take into account many nuances, of the main points it is worth noting:

• performance (power) of heating equipment, the calculations take into account the percentage of heat energy loss;
• feed rate of heated air masses;
• the diameter of the air ducts, great attention is paid to the aerodynamic characteristics of the line.

Incorrect calculation of air heating, as well as illiterate installation, can nullify all expectations. As a result, you can get not a comfortable microclimate, but negative sensations from the noise and vibration of the equipment, overheating or insufficient heating of the system, and similar inconveniences.

The project is being developed at the stage of building a house. This will make it possible to provide for all technological openings, niches and other structural elements for placing equipment, devices and system elements.

Air mass heaters

The main element in the installation of an air heating system is the equipment designed to heat the air streams. It is from him that the line departs, with the help of which the heated air is evenly distributed throughout the rooms. Manufacturers have a wide range of equipment that differs technical characteristics, installation methods, additional elements, etc., as they say, for every taste and wallet of the consumer.

Air heating systems use air heaters that heat the air at the time of its passage through the mains and heat generators operating on combustion of various kinds fuel:

• gas (natural or liquefied);
• electricity;
• liquid fuels (e.g. diesel);
• combined option - universal combination of water and electricity.

When choosing air heating at home, pay attention to the possibility of changing the fuel burning rate. Gas-powered equipment must be equipped with an automatic shutdown and shutdown system, as well as temperature control sensors.

It is worth noting that some types of boilers can be used not only for heating, but also for organizing hot water supply and a "warm floor" system.

Dampers, diffusers, grilles

• Dampers and valves are used to adjust the air pressure when it is supplied. To adjust the throughput, these elements are installed on each feed channel. In areas where fresh air flows from the street, adjustable dampers must be installed.
• Diffusers and grilles are connected to each channel located in the premises. They serve for the distribution and separation of air flows (air conditioning, ventilation, heating).
• For convenient operation, such elements are equipped with movable shutters, which makes it possible to regulate the pressure of air flows.

The main steps for installing air heating with your own hands

• After preparing all the elements of the system, you can start connecting them.
• First, the installation of the main main canals for the inflow and outflow of air masses is carried out.
• Wiring from auxiliary pipes is connected to the leading channels, into the holes made. The seams are sealed with special tape.
• For longitudinal and corner joints, H and L-shaped profiles are used, which can be fixed with glue.
• To create a more uniform air supply at the ends of the channel (up to 50 cm), it is not recommended to make taps.
• Dampers are mounted to the feed shafts.
• Diffusers can be chosen both round and rectangular, the latter, by the way, will reduce the passing air flow.

• For the return air intake, a pipe with a cross section of 125 mm is taken. The previous sidebar guidelines can be used here as well.

Do not install the air conditioner yourself. But it is quite possible to mount a humidifier. This device requires not only water, but also a sewage system, where non-evaporated water will drain.

The air heating system is characterized by rather complex installation work, including project development and selection of all components. Therefore, it is recommended to contact a specialized company for the installation of all elements. Incorrect installation, at best, will lead to uneven or insufficient heating of the room. In the worst case, it will come to dismantle the entire system, and this is unnecessary costs, damaged repairs and irrecoverable loss of nerve cells.
