Geothermal heating. Geothermal heating of a private house: price. Geothermal heating by one's own hands

Everyone dreams about a good comfortable home. And one of the main components of the dream is the right atmosphere in the room, that is, when in winter the heat, and in the summer - there is a comfortable coolness. At the moment there are many types of heating systems, so there is a choice. Somewhere and now they heat the dwelling by burning wood, somewhere they prefer peat or coal, and some use natural gas or electricity for this purpose. Different types of heating and prices are different. There are problems associated with the safety of the heating system, as well as environmental issues.

Alternative to tradition

Quite often you can hear that the optimal option for heating a house is the use of natural gas. It is cheaper than other sources of heat, but there are also certain problems. Not all natural gas is available, since gas pipelines have not yet been carried out anywhere. The gas column needs constant monitoring and maintenance. In addition, you must comply with safety regulations, as well as pre-authorize from special offices.

There is such an alternative as geothermal heating. This idea is based on the principle of physical transfer of refrigerant from the environment of thermal energy. The most important advantage of geothermal energy lies in the fact that it is completely independent of the environment, the time of the year and the time of day, and is also almost inexhaustible. These properties are deprived even of solar energy, which also refers to renewable resources. This technology was used successfully enough in the eighties of the last century in the Soviet Union. However, in those days it was inaccessible and very expensive. At the moment the situation has become completely different.

Russian developments in the field of renewable resources

At the moment, Russia can not boast of the presence of unique developments in this field. After all, they also require intelligence, certain studies. Geothermal heating, based on the use of the same energy, has such a basic merit as total independence and practical inexhaustibility. Now it is possible to speak about incredibly great opportunities for using the heat of the earth's depths as an important perspective. Water or a mixture of steam and water can be directed to the needs of heat supply and hot water supply, as well as to generate electricity for various purposes. It all depends on the temperature.

High-temperature heat should be used to generate electricity and heat. The station has a certain device, depending on what geothermal energy sources are used there. If there is a source of underground thermal water in the region, they can be directed to hot water supply and heat supply.

Geothermal heating systems are used every day more and more, since such heating has many advantages, including safety, environmental friendliness and economy. One of the main problems is the need to re-inject water into underground aquifers. Typically, thermal waters contain many salts, as well as toxic metals and a variety of chemical compounds. Because of this, it is impossible to discharge such waters into surface water systems.

So far, there are not many geothermal stations in Russia. However, from year to year there are more and more supporters and users who prefer geothermal heating.

How it works?

It is very difficult to state the principle of the operation of such an installation in an accessible form, since it has a rather complex design. It's easier to explain by resorting to some abstract example. It is necessary to imagine a system in the form of a refrigerator, only vice versa. Here the role of the freezer is an evaporator located in the depths of the earth. The condenser, made of a copper coil, brings the temperature of the air to the desired level. And the temperature of the evaporator is much lower than that of the surface. In such systems, the energy of the earth is used not only for heating, but also for conditioning.

Geothermal heating involves the use of reliable and durable compressors based on innovative technologies of refrigerator systems, which allows creating such unusual methods of transforming heat from earth depths into quality heat, which is further used to heat the room. The heat pump in such a system is one of the most important components.

The basis of the system

As a basic principle of the operation of such a system, the physical transfer of thermal energy to the coolant from the environment is used. This can be observed in any refrigerator. Geothermal heating of a private house assumes that more than 75% of the total thermal volume allocated during the operation of such systems is the energy of the environment, which accumulates and enters the premises of the house. That is why this energy is characterized by such an excellent property as self-healing. It turns out that the geothermal heating of the house is safe for use and is incapable of causing any damage to the energy or ecological balance of the planet.

Development of technology

Geothermal heating systems began to be developed after the energy crises of the seventies of the last century. When innovative installations only appeared, only simple families could use them in their home. However, later the systems became more and more widespread, due to which their cost became more accessible. Now a family with an average income can use geothermal heating, the price of which ranges from 35-40 thousand rubles and has become affordable for many. Naturally, work is still under way to improve the equipment intended for these purposes. Every year there are more and more economical and convenient units.

Ecological compatibility

Geothermal heating of a private house, whose price is becoming more affordable every year, is based on a qualitatively different fuel, unusual for us. Heating and air conditioning of an individual dwelling is carried out through the energy of the earth, by means of which it is possible to create optimal conditions for life. In addition, such heating is environmentally friendly, as its use does not lead to environmental pollution by toxic emissions and harmful wastes.

Safety in operation

Installations that carry out geothermal heating work without the use of combustion processes. It is because of this that any preconditions for explosions or fires are completely excluded. As important advantages are often called the lack of the need to purchase and install additional hoods and chimneys, which is required for heating systems operating on other principles. During the operation of such a system, no harmful odors or fumes appear in the house. In addition, it should be said about the quiet operation of such a heating system, as well as its compactness.

If we compare geothermal installations with solid fuel or liquid fuel systems, it is worth noting that they not only do not violate the interior of the dwelling, but also do not require time to solve the problems associated with the acquisition, delivery and subsequent storage of fuel, since the energy of the earth can be called inexhaustible .

Price of issue

When it comes to choosing devices and heating systems, one of the first places is always financial issues. Installation of a geothermal heating system will require significantly more costs than diesel or gas equipment. However, we should remember about a much lower level of energy consumption. So in the long term, the purchase and installation of such a system are more economical.

Space saving

There are several ways in which you can significantly reduce the space occupied by heat pumps if you are doing geothermal heating yourself:

• Use special underground probes, for which a contour filled with antifreeze is lowered into the well;
• Use of warm groundwater, which requires drilling a deep well, and the water pumped out by the pump will be run through the heat exchanger;
• The probes are laid horizontally at a level below the ice level of the bottom of water bodies in winter.
