Air heating of a country house: ideas for self-improvement

Having decided to build a cottage or a cottage, sooner or later, you will face the problem of choosing a heating system that will be equally efficient, functional and economical. Currently, it is the air heating of a country house that seems to be the most progressive solution, thanks to which it is possible to ensure maximum comfort of living in a modern low-rise housing construction object.

The air-heating system is designed to provide thermoregulation, during which air of the required temperature is fed directly into the room. This type of heating for a variety of characteristics more efficiently than traditional radiator or stove counterparts.

Consider the benefits of this temperature control circuit.

Operational features

• Heating of a country house with warm air is not concentrated around the stove or radiator. Therefore, moving from one area of ​​the room to another, you will not feel sharp temperature changes.
• In building objects, heated by air, almost completely eliminated fogging of windows. In addition, there are no wet spots on the walls, and there is no swelling wallpaper.
• The implementation scheme of air heating is equally suitable for sale in buildings of residential, public and industrial use.
• Heating by means of heated air does not provide for the need for a complex system of circulation of the coolant. As a result, the project price is low and an order of magnitude more affordable than the cost of systems based on the use of pipelines, radiators, boilers, etc.
• Air heating of the enclosed space is safe and characterized by a long operational resource in comparison with the systems based on the use of the heated liquid coolant.

Air heating has no leaks, which will cause the restoration of the house. If even the tightness of the duct for one reason or another will be broken, it will not be a threat to the safety of people and the safety of property.

• Heating based on the use of air ducts, unlike systems based on radiators and piping, may be used intermittently.. That is, you can move into a country house in the winter and in a short time to heat the air in the room to the required temperature.

If the operation of conventional systems based on the use of a liquid coolant is temporary, the contents of pipes and radiators will have to be drained to avoid mechanical damage to the pipeline. This advantage makes air heating the optimal choice for both country houses and small hotels where the influx of visitors is not constant.

Main varieties

Despite the fact that the history of heating the premises with warm air has a number of centuries, the greatest productivity and efficiency of use are characterized by modern developments. Consider what schemes for the implementation of air heating are on the market today.

Direct-flow systems

The instruction of the operation of the circuits constructed on the direct-flow principle is characterized not only by efficiency, but also by simplicity.

In the lower part of the construction site, a heating unit is used in which a particular fuel is burned, for example, firewood or coal. Heated air thus rises up by gravity through cavities provided for in the floor and wall structures.

After passing the cycle and heating the room, the coolant is discharged to the outside through the hood provided in the upper part of the house. The system as already mentioned, is simple to implement, but its efficiency is low, since a large amount of heated air, without releasing heat, completely goes into the pipe.

Recirculation systems

With the beginning of the use of natural gas as a fuel, air heating has become more efficient and economical. Moreover, the heated air became cleaner. Again, with the beginning of the use of modern filtering equipment, it became possible to supply heated air directly into the room, making a closed cycle of turnover.

The recirculation scheme is also called gravitational, since air, due to gravity, circulates without the need for any injection device. In the event that the construction of the building object impedes the circulation of the coolant, the recirculation scheme is complemented by devices characteristic of forced ventilation.

The modified scheme involves the injection of hot air through axial fans - when arranging a country house, and centrifugal fans - when arranging industrial premises.

Important: Air heating, implemented by recirculation scheme in a private house or apartment, involves the use of humidifiers and ionizers.

Recently, recycling in combination with the inflow of a small amount of outside air has become increasingly important. In this case, the exhaust air after the release of heat is gradually removed to the outside and is replaced by fresh air.

Known examples of the implementation of the combined air-water or air-oil heating schemes. Such systems have been used in the construction of centralized heating in large buildings or immediately in several low-rise individual buildings.

Recommendations for self-production

To date, there are many organizations in which you can order the installation of air heating systems "turnkey". Unfortunately, the price of such a service will be high, and therefore it is advisable to do all the work with your own hands.

However, before you begin assembly, you must purchase the following equipment:

• A heating element. You can purchase a variety of heating devices, but as the statistics show, a modern gas heat generator is the best choice.

Despite the fact that the price of such equipment is low, it is justified by a long operational resource and economical fuel consumption.

• Air ducts (ventilation ducts) for air circulation. Channels can be of two types - flexible and rigid.

Flexible pipes should be purchased if they can be installed hidden, for example, in a decorative box. Rigid boxes are used if the surface of the walls on which the box is mounted is ideally even. Given that the air ducts are purchased for the heating system, products made of galvanized steel will be a reasonable choice.

• Aluminum reinforced adhesive tape designed for sealing hermetic joints of ventilation ducts.
• Decorative grilles, through which the air will be taken and supplied.
• Mounting fasteners and tools for processing galvanized steel.

After all the necessary equipment has been purchased, it's time to start the installation work.

• First, we determine the location of the heating unit. As a rule, a small room with good ventilation is allocated for this purpose.

If natural gas equipment is used, care must be taken in drawing up and coordinating the project with the appropriate services.

Important: The installation of heating equipment operating on natural gas and commissioning should be carried out by a qualified technician.

• After the heating equipment is installed and tested, proceed to the installation of air ducts.

There is no universal layout of the ventilation channels in the room, so we place the pipes based on the characteristics of our construction site. Fastening the pipes to the heating unit is carried out in strict accordance with the instructions of the device.

• If, in accordance with the scheme, it is intended to install a forced air supply to the supply air duct, then install a duct fan.
• If, during the trial run of the assembled system, the air ducts produce excessive noise, the pipes can be wrapped with sound insulating material. Given the characteristics of the use of air ducts, insulation should be heat resistant.

Conclusion

Now that we know what air heating is, and on what basis it works, we can choose the equipment that will meet the design features of your home.
