Nowadays, different types of heating are used, it can be: gas, boilers, fireplaces, heat generators, and other miscellaneous units, both purchased and made by hand. In this article, we will take a closer look at air heating of the house and interiors.
When arranging a private home, it is extremely important to choose the most suitable heating system. It is worth paying attention to the method of heating the house using air heating.
This is a specially developed thermoregulation system, in which the heated air is first heated to the required temperature, and the warm air enters the interior.
Compared with traditional stove and radiator systems, this one has a number of special interesting advantages.
Heating zones of the dwelling are not tied to the location of radiators and stoves, so there are no sudden temperature changes.
In a building with air heating, there are practically no swollen wallpaper, traces of moisture on the inner walls, and condensation does not occur. Since the air heats up evenly, this type of heating is great for rooms with large volumes - warehouses, halls, workshops, etc.
This the type of air heating of premises does not require the arrangement of a complex structure for the circulation of the coolant.
When radiators are used, heated oil or high pressure water moves through the battery system and piping.
But a heated coolant, and even under high pressure, is a rather aggressive medium.
Therefore, all elements of the heating system must meet the necessary requirements for tightness, corrosion resistance, and so on. Even the smallest damage to one part of the system can cause the used thermal fluid to enter the living space. And this is a certain risk for the safety of property and for the safety of people.
Air heating has no such disadvantages.
In winter, the unused radiator heating needs to drain the coolant. Otherwise, the frozen substance will clog the radiators and pipelines, which will permanently disable the entire system.
Water, turning into ice, expands markedly, thereby threatening the integrity of the entire heating system of the home. Air heating, meanwhile, can be switched off and on again freely in any season.
This feature is especially important for small seasonal hotels that host guests for a limited time, or for country houses visited by the owners during the cold season only on holidays and weekends. The relatively low unit cost of air heating equipment is also an important factor.
Since ancient times, people have tried to heat their homes by means of hot air. In the notorious Pompeii, ashes preserved the foundations and walls of buildings, which made it clear that even then people were using ancient systems of centralized air heating systems.
They were called hypocaust.
The next revival of heating systems of this type happened already in the 14-15th centuries.
Interesting fact: Heating of floors and walls with hot air was carried out in the chambers of the Kremlin before a similar method was used in Europe. Surprised foreign ambassadors talked about such a curiosity in their homeland, and for some time such a home heating system was called Russian heating.
Already in modern times, air heating has found its widespread use, at the moment when huge masses of people moved to cities in search of a better life.
The first heating in the houses of the then industrial capital of the world, London, was of this kind.
The earliest air-assisted heating systems had a fairly simple design. The air was heated in a specially arranged place at the bottom of the building. Used for this combustion of coal or charcoal, firewood. By gravity, warm air rose up through specially arranged cavities in the walls and floor, and through the outlet holes in the roof it was removed away.
The air of the rooms received heat from the walls and floors heated by passing air, one might say indirectly.Such a system was called direct-flow, and had a rather modest efficiency. The reason for this is that a large amount of heat was spent on heating the entire depth of the floor and walls, as well as on "heating" the street. After all, a still warm air stream came out into the street. But it was precisely because of this temperature difference outside and inside the system that a thrust was formed, which improves the heating process.
The beginning of the use of natural gas as a fuel of a new type made a real revolution in heating by air methods. Heating of air with a fairly clean type of fuel, the appearance of special air filters - all this made it possible to pump hot air mass into the room, creating a closed cycle of air circulation in the building.
The air flow heated by electric or gas heaters is supplied through specially equipped air ducts to the upper part of the building.
The air gives off heat and gradually begins to descend, returning back to the heater, and it is occupied by other, hotter rising streams.
A similar arrangement of the recirculation system is called gravitational, since the movement of air occurs only due to the natural force of gravity, without the use of any devices.
In the event that the structure of the building does not allow air to circulate freely, a forced ventilation system is arranged.
To pump heated air into the premises, and take it back to the heater, they are carried out by means of special fans. Such heating with recirculation is a fairly inexpensive and simple heating option, perfect for warehouses, workshops and other non-residential premises. Why uninhabited? The fact is, passing through the heating element many times, the air loses its quality.
Therefore, when heating an apartment or house using this type, the air will have to be ionized and humidified.
Exhaust air is gradually removed outside, and fresh air from the street takes its place. There are also all kinds of combined air / oil or air / water heating systems used for district heating of a small building complex.
First of all, you need to think over everything, and choose the most important thing - a heating element for the system. Very often, special gas generators are used to heat residential buildings and apartments. Which heater model do you prefer?
The correct choice is based on the area of the room as well as the standard fuel consumption of the unit.
There are a lot of good reviews about devices made in the Scandinavian countries. They, of course, are not budgetary, but they are perfectly adapted to long harsh winters. What else do you need besides the heat generator itself?
These are special pipes designed to circulate heated air through them. Rigid ones also require special "curved" elements called bends. You will also need to take care of the required number of tees. Their number depends on the scheme and complexity of the circulation system. Air ducts are made of various materials, but more often galvanized steel fixtures are used.
It is most convenient to plan a suitable heating system for a house in advance, even at the initial stages of construction. Then you can take into account the location of future elements, and make special inconspicuous niches in the walls for conducting air ducts.
In the same case, when the system is designed and installed in an already finished house, such air ducts are masked with false walls and false ceilings.
Air-thermal heating of a building is a profitable and very promising model for arranging a comfortable home, which is worth paying close attention to. Be that as it may, it's up to you to choose!
