Air heating at home. Forum experience. Air heating of a private house - economical and really efficient heating Air heating systems for private houses

Under air heating understand a special system of thermoregulation. It involves the supply of air heated to a predetermined temperature directly into the premises of a residential or non-residential building. Compared with stove and radiator systems, such heating is characterized by a number of advantages.

Air heating at home - many advantages, but few disadvantages

Many modern heating systems have quite serious shortcomings. This forces property owners to look for more efficient heating options. In recent years, air systems have begun to gain considerable popularity, which equally heat both large premises (both residential and industrial or administrative), and very small houses with several rooms. This type of heating is characterized by the following advantages:

1. There is no need to spend money on the purchase of pipes and radiators, as well as on their installation.
2. The efficiency of air systems is approaching 90%.
3. The possibility of arranging, within the framework of one project, a combined complex for maintaining the required temperature in a private house (air conditioning plus heating).
4. Complete safety of equipment operation. The systems we are considering are equipped with highly sensitive automation. It is she who controls the operation of heating every second. As soon as any failure occurs, there is a danger of leakage, the automation switches off the used air installations.
5. Low energy consumption, affordable cost and quick payback of installed heating equipment. Air will be truly profitable and economical.
6. Aesthetics. The dwelling does not need to be cluttered with radiators and highways connecting them. Due to this, all the free space in the rooms can be used to create chic interiors.
7. Easy operation. Starting the system, selecting the required mode of its operation, stopping the equipment and many other processes are carried out in automatic control mode. The probability of making a mistake on the part of a person when using air heating is reduced, in fact, to zero.

In addition, the described type of heating is durable and reliable. If the heating project is drawn up correctly, the installation is completed without errors, and regular maintenance is done on time, the network will last 20–25 years without the slightest accident. We also note the uniquely high rate of air heating. In cases where the temperature in the room was zero or negative, after starting the equipment, it takes a maximum of 30-40 minutes to fully warm up the room.

The disadvantage of air heating is the need for fairly frequent (and necessarily regular) maintenance. Another disadvantage is the energy dependence of the described complexes. The equipment is powered by electricity. If there is no light in the house, the system will stop. There is only one way to solve this problem - to take care of installing an additional (autonomous) source of electrical power.

Varieties of systems - how to choose the best one?

Familiarization with the types of air heating makes it possible to choose the configuration that is suitable for a particular residential building in terms of all characteristics. The systems of interest to us are classified according to

the place of installation of the equipment;
air circulation option;
type of heat exchange;
scale.

The air heating system can be suspended or floor-mounted by location. The first option involves the installation of channels (air ducts) to fill the room with heated air under the ceiling, the second - under the floor. Important. In both cases, the channels are easy to disguise using decorative elements and plinth structures. In private housing construction, experts advise using the floor scheme, as it first heats the lower part of the room, providing maximum comfort to the inhabitants of the home. When installing suspended ducts, there is a chance that the heat will not be able to reach the floor surface. This will bring some discomfort to the person.

According to the type of air circulation, air systems are classified as forced and natural. This moment is of great importance. With natural ventilation, the rise of air is provided by its heating. The hot mass is sent to the air ducts, heats them up, and then goes back to the heat exchanger. If during the operation of the system cold air from the street enters the room (for example, through windows or doors), it will accumulate near the floor. As a result, the lower part of the room will always be cooler.

When using the forced ventilation described above, there is no problem. In this case, the system is equipped with a special fan. Its task is to form a given pressure at which heated air moves around the room much faster. Due to this, the room is heated in a matter of minutes. Cold air in the presence of a fan simply cannot change the temperature regime provided by the system. Nuance. The ventilation equipment makes a noticeable noise during operation.

If you consider yourself overly susceptible to extraneous annoying sounds, it is better to opt for networks with natural ventilation.

Heat exchange in the described systems can be supply and recirculation. Here you need to remember the following. If the heating takes air exclusively from the street, then we have a supply system. For its arrangement, fans are needed that can direct street air masses to the heating installation. If the air is taken from both outside and inside the house, we are talking about recirculation heat exchange.

In terms of scale, air heating is classified as one of two types. The first one is local. It is suitable for heating private area housing construction. The second type is central. This scheme is good for warehouses, entertainment facilities, sports facilities, large stores and so on. It makes little sense to introduce it into a home (even a large one).

Heating device - what elements are needed?

Regardless of the type of system chosen, for its arrangement you will need to purchase:

thermal generator;
air ducts;
fan;
gratings for air intake and supply.

A heat generator is a furnace (boiler) for burning a certain type of fuel in order to heat the air. It can operate on any fuel. The air heater uses natural gas, liquefied or liquid fuel, even wood or coal. Important point! Boilers for the heating systems under consideration make it possible to switch from one fuel to another at any time. If the heat generator is powered by natural gas, it is enough to change the burner on the unit to start using diesel fuel. This is literally a matter of minutes. In cases where it becomes necessary to burn natural gas instead of liquefied gas, you just need to install a replaceable nozzle on the unit, which is characterized by a different cross section of the through holes.

Air ducts are branched-type channels designed to supply heated air flow to the heated rooms of the house. These devices are made in a round or rectangular shape. The difference between them is insignificant, but it is. Round ones have a cross section within 20 cm, they are described by a small resistance (aerodynamic). Due to this, the heating efficiency is slightly increased. The connection of individual parts of round air ducts is carried out with studs or clamps. The cross section of rectangular channels is usually slightly larger. Such designs are easier to fit into the home interior. For this reason, they are used much more often than round ones to supply heat to private dwellings.

The air heating device requires the use of some other elements. Air intakes and air distributors are always installed at the outlet areas of air ducts to heated rooms. A fan is also required. It blows heated air into the ducts. The fan is mounted under the combustion chamber of the boiler being used. It is usually equipped with a filter device that purifies the air from fine dust particles and other impurities.

Calculation and independent installation of the heating system - will it work?

Calculation of air heating and drawing up its exact design are mandatory steps in installing the system. These operations are necessary for:

determining the speed at which air should move;
selection of a heating installation with suitable power characteristics sufficient to heat the house;
obtaining an accurate installation scheme for all elements of the heating network;
determining the aerodynamic index of the system and the amount of heat leaving the house through door and window openings, floor base, roof, wall surfaces.

It is quite difficult to perform a competent calculation with your own hands. You need to have knowledge of a heating engineer. We recommend entrusting the design phase to specialists. And installation work, having a heating scheme at hand, you can do it yourself.

The video below shows the sequence of actions to be taken when assembling and connecting the air heating system. The first step is to select and . It must have such modules - regulation of the intensity of combustion and automatic control of the safety of the operation of the equipment. A unit without such systems is not suitable for arranging air heating.

We connect air ducts to the boiler installed in the selected place. It is allowed to use both metal flexible channels and galvanized steel products. The first are connected to each other and sealed with special reinforced tape, the second - with studs, clamps. If a combined heating and air conditioning system is installed, the air ducts must be carefully insulated. Then condensation will not form on their surface.

After laying the air ducts, you can mount the grilles, and then decorate the laid channels for the existing interior (of course, if you have planned such work). Watch the video carefully, listen to the advice of experts, and you will definitely be able to build a high-quality and durable air heating system. May your home always be cozy and warm!

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 fairly effective way to maintain optimal temperature conditions. The article will discuss 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 owners.

So, for example, by combining the heating system with ventilation, an influx 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 switched on only to maintain the optimum temperature, thereby saving resources (gas, electricity, etc.).
The system can be switched off for a long period without any consequences.
Due to the absence of radiators, the installation of the system is easy, and the interior only wins in such cases.
Air flows quickly and evenly heat the room. The efficiency is 90-93%.
Complete security. There is no risk of leaks, freezing of water, fire hazard.
It is possible to connect duct equipment that works to maintain a certain level of humidity.

Air heating scheme

Of course, ideal heating systems do not exist. In a barrel of honey, you can add a fly in the ointment.

With improper design, there is a possibility of increased noise and an imbalance in the supply of heated air.
Air ducts can have a fairly 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 flows are distributed along the highways to each room. The products of combustion exit through the chimney.
Warm air displaces cold (law of physics) down to the air intakes. This creates a natural circulation. However, due to drafts from windows or doors, the process is disrupted and warm air masses accumulate under the ceiling. This is the only disadvantage of the gravity system.

If forced ventilation is used, then the distribution of air masses occurs faster and more evenly. 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

Circulation is carried out mechanically, when a fan is used to blow air, or in a natural way due to temperature differences. The system can be central, designed to heat large areas, or local, where the optimum temperature is maintained in rooms with a modest square footage.

Air exchange happens:

recirculation, when the cooled air in the room flows back into 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, thanks to the influx 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 content of dust in the air by means of filter elements. In this case, the selection of equipment depends on the desired degree of purification: from standard to sterility. To prevent 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 drafting 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, from the main points it is worth noting:

productivity (power) of heating equipment, the percentage of loss of thermal energy is taken into account in the calculations;
the rate of supply of heated air masses;
the diameter of the air ducts, much 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 equipment noise and vibration, 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 accommodating equipment, devices and system elements.

Air heating video

Air mass heaters

The main element in the installation of an air heating system is equipment designed to heat air flows. It is from him that the highway departs, with the help of which the heated air is evenly distributed throughout the premises. Manufacturers widely represent equipment that differs in technical characteristics, installation methods, additional elements, etc., as they say, for every taste and consumer budget.

In air heating systems, heaters are used that heat the air at the time it passes through the mains and heat generators that burn various types of fuel:

gas (natural or liquefied);
electricity;
liquid fuel (for example, diesel);
combined option - a universal combination of water and electricity.

When choosing air heating at home, pay attention to the possibility of changing the rate of fuel burning. Gas-fired equipment must be equipped with an automatic shut-off and switch-on 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 the organization of hot water supply and the "warm floor" system.

Dampers, diffusers, grilles

Dampers and valves are used to regulate the air pressure when it is supplied. To adjust the throughput, these elements are installed on each feed channel. In areas where fresh air is supplied from the street, adjustable dampers are mandatory.
Diffusers and grilles are connected to each channel located in the premises. They serve to distribute and separate air flows (air conditioning, ventilation, heating systems).
For convenient operation, such elements are equipped with movable blinds, 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 begin to connect them.
First, the installation of the main main channels 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 a special adhesive 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 tie-ins.
Gates are mounted to the supply shafts.
Diffusers can be chosen both round and rectangular, the latter, by the way, will reduce the passing air flow.

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

It is not worth doing the installation of the air conditioner with your own hands. But to mount a humidifier is quite capable. This device requires not only water, but also sewerage, where unevaporated water will flow.

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 specialized companies 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 these are extra expenses, damaged repairs and irretrievable loss of nerve cells.

Every property owner wants to have an efficient and reliable heating system in their property. It is desirable that it creates the most comfortable conditions in the premises, at a minimum cost. At the moment, air heating is one of the most promising and modern types of heating.

Features of space heating with air

Such systems have a lot of advantages, the main ones are as follows.

Advantages of air heating

Due to the very principle of operation, such heating has a very high reliability. In particular, there is no danger of pipeline freezing, leaks, etc.

The system is economical as it is universal. It is possible to combine space heating with air conditioning, ventilation, humidification and air purification. All these utilities will use the same air duct system. Thanks to this, the price of work will drop sharply, as you will save on building materials and installation.
No thermal energy consumption for heating).
If you use not only ordinary filters, but also additionally carbon ones, this will eliminate all extraneous odors.
Air heating has a high efficiency - up to 90%.
Heating with warm air is automated. The system itself adjusts to produce the required amount of heat. While you are away, you can reduce the heating of all rooms to +6/7 degrees. This will not allow the dwelling to cool down, and at the same time it will significantly save energy resources.
The rooms quickly heat up to the required temperature regime. Depending on the properties of the installed system, as well as the volume of the room, it can be heated in half an hour / hour.
Simple and quick assembly of such heating.
Simple ongoing maintenance.
The service life is quite long - about 30 years.

Cons of such heating

There may be slight noise in heated rooms.
If you do not put special dust filters, then along with the heated air, dust will also move around the premises.

Note! A significant drawback when heating the house with air is chosen is that there is a large difference in temperatures near the floor and ceiling. In ordinary rooms, it reaches 10°, in large and high rooms, this difference increases to 20°. As a result, in winter it is necessary to increase the thermal power of the system.

How it all works

Air heating is increasingly chosen in the construction of real estate. This type of heating is used in private houses and cottages, commercial and industrial premises, warehouses, agricultural and sports facilities, etc.

The main working element of the air heating system is the heat generator. As a rule, it works on gas or electricity, less often on diesel or solid fuel. The heat exchanger and burner, in turn, are the main parts of the heat generator itself.

The heat exchanger is blown inside by air. At the same time, heated combustion products (gases) pass through it. The air heated up to +45/65° due to them enters the heated rooms through the air duct system. There it gives up its excess heat to a cooler surrounding analogue, and then, through the return pipes of the air duct, it returns to the heat generator for the next heating.

It should be noted that the circulation of air flows in such a system is of two types:

natural, created as a result of a temperature gradient;
forced, in this case, the air must be blown by a fan.

The main types of such systems

As shown in the photo, air heating, according to the principle of its operation, is divided into three types:

fully recirculating system;
analogue with partial recirculation;
direct heating.

Recirculation heating

In a similar design, constant circulation and heating of air in the premises is carried out. Ventilation, at the same time, can be both natural and forced. In the latter case, additional equipment will be required.

Usually, such heating is mounted on the basis of freely dissipating heaters. It should be noted that the ventilation and heating collected in this case are completely independent of each other.

It is also possible to mount a recirculating air system based on duct heat generators.

Heating with partial supply

Such heating uses exclusively duct air heaters. Its main difference from the above option is the combination of air heating and forced ventilation. In such a system, on the exhaust (return) branch of the duct, a branch is mounted that goes outside the building, necessary for the intake of external air.

Note! At the same time, the ratio of supply and recirculation air in such heating varies in the widest range. Depending on the selected system design, they can be mixed before or after (if an additional fan is used) the heat generator.

The first variation is more rational, as it makes it possible not to use an additional cooler when installing heating. This significantly reduces the load on the main fan.

However, there are systems where air mixing occurs after the heater. With this option, the room air heated to a high temperature is mixed with the cold supply air. In this case, a mixture of a given temperature is obtained. In summer, such a design can play the role of forced ventilation. And if you install additional devices, it will humidify and cool the premises.

Supply air heating option

In such a system, only the outside air is heated. As any instruction indicates, when installing such heating, it is imperative to design powerful exhaust ventilation.

It should be said that it is easiest and cheapest to make heating based on indoor air recirculation with your own hands. But it is not always possible to use such heating, based on sanitary requirements, as well as building codes.

Note! When creating a project for such a system, it is necessary to take into account not only the heat losses of the enclosing structures of the building, but also the heat losses from the active ventilation of the premises. Dynamic hypothermia is also important. They can be associated, for example, with the opening of the entrance gate. In addition to all this, one should take into account the height of the premises, as well as the frequency of air exchange in them.

In foreign countries, this type of space heating has long been popular, such as air heating, which is an alternative to traditional water heating for us. Recently, in our country, many homeowners have begun to switch to air heating, which is associated with a number of advantages of such a solution.

In this article, we will take a closer look at its device and its main features.

Principle of operation

The principle of air heating is based on the circulation of warm and cold streams. The heat generator heats the air masses that enter the room through the air ducts, as a result of which the warm air displaces the cold air masses that enter the heat generator through the same air ducts.

Gas, kerosene, etc. can be used as an energy carrier for heating air masses. If heating is carried out as a result of a combustion process, then the system must be equipped with a chimney.

As a rule, this type of heating is used in private houses and cottages, as well as in industrial and commercial premises, sports facilities, etc. The main working element of the system is a heat generator, which most often runs on electricity or gas.

The principle of operation of this device is as follows:

The heat exchanger inside the apparatus is blown with air.
In parallel with this, combustion products pass through the device, due to which the air is heated to + 45/65 degrees Celsius.
Then the hot air enters the room through the ducts, where it gives off excess heat to the cold air.

Warm air heating can be implemented in two ways:

It should be noted that air heating is a rather complex system of heat regulation, which involves mixing fresh outside air with the old one. Thus, in addition to heating, there is also ventilation of the premises.

Note! Installation is desirable to carry out at the stage of building a house, as this will hide the air ducts in the walls and ceilings.

Features of air heating

Advantages

Unlike traditional water heating, heating in this way is carried out without intermediate links, such as a heat pipe and radiators.

In addition, this type of heating has a number of other advantages:

Economy and high efficiency, since there is no intermediate coolant. As a result, even a large area heats up very quickly.
Comfort- thanks to modern equipment and automation, air heating systems maintain not only the optimum temperature, but also the humidity of the air with high accuracy. In addition, filtering units provide purification of air flows.
The system does not interfere with interior design, since there is no need to conduct a pipeline and install heating radiators.
Security- since there is no coolant, the possibility of a pipeline break and flooding is excluded.
Versatility- the system can be used not only for heating, but also for ventilation and air conditioning.
Not complicated and fast assembly of the structure.
Simple instruction on the use and maintenance of the equipment.
The service life of the system is up to 30 years.

Minuses

Any heating options have not only advantages, but also some disadvantages.

Air heating is not an exception in this sense, although there are not many disadvantages:

Possibility of slight noise in heated rooms.
The need to use filters, otherwise dust will enter the premises along with warm air.
High cost of equipment.
Temperature difference at the bottom and top of the room.

Thus, the disadvantages of this type of heating are unprincipled, especially if all their advantages are taken into account.

Mounting Features

It is not difficult to equip air heating in the house with your own hands, you just need to prepare a system plan and purchase all the necessary elements. It should be noted that the plan also implies the execution of the calculation.

Incorrectly performed calculation can lead to failure of the heater, draft in the premises, as well as noise and vibration during the operation of heating devices. Therefore, it is better to entrust the preparation of the project to specialists who will determine the optimal power of the equipment and the location of the air ducts.

As for the equipment, the following elements will be needed to install the system:

In the photo - ventilation grilles

Air ducts, sleeves and other elements of air heating are usually purchased ready-made. The price of all elements of the system is higher than equipment for traditional heating, but in the heating process this difference quickly pays off.

The assembly process itself is reduced to the installation of air ducts according to the scheme. The parts are connected to each other with clamps. When the distribution of air ducts in the premises is completed, the heat generator is connected to the system.

Since the equipment contains many electronic devices and sensors, after installing all the structural elements, it is necessary to debug the system. This work should also be done by specialists.

Advice! Installing additional elements, such as a humidifier or a filter above the stove, will make the system more functional.

Here, perhaps, are all the main features of air heating and its device.

Conclusion

Heating a house with air is very efficient, and it also has many other advantages, which is why it has recently been considered the most promising. Its only serious drawback is the high cost of equipment, however, they pay off pretty quickly.

From the video in this article, you can get some additional information on this topic.

Air heating (VO) is a common practice in the private sector. Such systems allow you to heat the room autonomously, cool if necessary, control the microclimate and give high efficiency rates. To decide whether you should decide to install such a system or stop at steam heating, let's look at the principle of operation, types, scope, positive and negative aspects of operation, design and installation features.

Principle of operation

The simplest example of an air heating system for a private house is an ordinary Russian wood-burning stove. To cook dinner and heat the room, you have to stock up on firewood and kindle the stove. The air around the stove gradually heats up and spreads around the room, thereby warming up the entire dwelling.

Natural gravitational circulation is based on simple laws of physics: warm air is lighter, so it tends to rise up, cold air sinks down.

The principle of operation of the air heating system is quite simple, the fan blows cold air, it is heated with a burner and then distributed throughout the house.

However, this heating principle implies natural air circulation. Modern systems operate with forced hot air supply. The flow is supplied by pumps and fan elements. Air ducts conduct warm air to all rooms of the house and heat them up. As it cools, the cold air sinks to the floor, where it enters the duct opening, and the cycle begins anew.

Circulation methods

Air circulation can be carried out in several ways:

with the inclusion of fresh air in the cycle (recommended);
without air supply from the outside (closed cycle);
co-current circulation - in this case, cold air is brought out, and a new portion is also received from the street.

Where is VO used

Scheme of air movement in the air heating system of a frame house, where the air duct is installed in hollow walls.

Air heating is recommended to be installed in private frame-type houses. Since the design of such a house provides for the presence of voids between the outer cladding and the inner coating, the air duct system can be installed in the hollow spaces of the wall, without affecting the decoration of the house.

Another option for installing an air system is to include it in the project of a future building. So, when erecting walls between them, technical niches are left for further installation of the system. If you plan to install air heating in a finished structure without such blanks, then you will have to deploy large-scale construction and rebuild the walls.

Device and types of air heating in private houses

Most often, the air heating system for a private house has the following components:

heat generator - usually its role is played by a water heater, which is responsible for heating the air;
air ducts to ensure the supply of warm air to the room;
fan to set the direction of air flow inside the room.

VO systems are formed according to gravitational or forced schemes.

Gravity schemes

The natural or gravitational scheme implies that warm air circulates due to a change in its density when its temperature changes. The main advantage of this type is that the system operates almost autonomously from the electrical network. However, due to disadvantages, the range of use of this approach is limited.

The work can be disrupted by a draft or an influx of cool air from the street, and then excessive heating of the air near the ceiling and strong cooling of the main part of the room are provided.

Forced Schemes

The main difference between the forced system is the presence of a fan that regulates the direction of air flow. The heat generator heats the air, the fan creates pressure and directs the masses through the pipes. Such ventilation systems are installed under the heater, into which air is cleaned from dust and foreign odors. After the heat exchanger, the air is directed to the air ducts, and its return is provided by return air ducts or ventilation grilles.

Advantages and disadvantages of air heating

To make a choice, consider the features of using such systems in private homes:

Heating of a private house, a fireplace acts as a heating element.

Estimated service life is 30 years. Usually, after a couple of years, the costs of VO are fully paid off to the owners.
No leaks or risk of pipe freezing, high efficiency, no intermediate transmission elements and low energy consumption.
Fans can "cooperate" with a conventional stove and supply warm air to all rooms. A well-known example is the fireplace air heating of a private house.
Filters and ionizers are able to purify the air of odors and eliminate harmful particles.
The system creates an optimal microclimate, producing additional air humidification or drying, depending on the characteristics of the climate and the room.
In summer, you can cool the room with additional draft ducts that supply cool air.
If you are not at home, the system runs at a minimum and quickly heats up when needed.
The main disadvantage is the need for power supply of the forced circulation system. and the need for backup power if power outages are anticipated.
Help for installing the system is laid only during the construction of the building or complex repairs are carried out with subsequent installation.
VO is quite demanding for repair and maintenance; with regular use, it is difficult to carry out a full-fledged modernization.

How to draw up a heating project

If you decide to install a VO system, you should understand and develop a detailed project. Key points to consider when planning:

heating rate (warm air supply) and room area;
the power of the heat generator, which is calculated based on the characteristics of the house and possible heat losses (state of doors, windows, walls);
dimensions of the ducts and the subsequent value of the air pressure loss.

Please note that for the optimal operation of the system, all calculations are made by competent specialists. Due to miscalculations and attempts to independently “estimate” the operation of the system, intense heat loss, strong noise and vibration during operation are possible.

Air heating installation principle

Air heating of a private house is mounted in the voids in the walls and floor, and this improves the appearance of the house, saving it from various pipes and radiators.

Elements of the system are mounted mainly in free cavities in walls and floors, which significantly ennobles the room. However, their installation must be planned not yet at the stage of building a house or a significant redevelopment should be carried out. To heat the room, special grilles are mounted on the walls to supply warm and take cold air. If the project provides for functional additions, then VO can crash into the air conditioning system and be combined with ventilation. The equipment itself is able to work from different power sources: gas, coal, electricity. For the rest, the VO determines an individual work plan for the installation.

One of the features of the system is that it is almost impossible to build air heating of a private house with your own hands, unless, of course, you have a sufficient technical base.
