How to make the heating of the land in a private house

Most of us understand that the use of coal, gas and wood as fuel is not without cost to the environment. However, the introduction of alternative energy sources is hampered by their high cost and efficiency, which are still inferior to traditional ones. But lately, manufacturers have increasingly begun to pay attention to such products, so we hope that soon they will be easier to install and less expensive.

Today we consider geothermal heating, which can be installed for a private house with your own hands. You will learn about the principle of his work, types, features and self-assembly.

It should be said that in European countries and the USA, heating from the earth is gradually becoming the main source of heating at home, but so far, such systems are only an alternative to more traditional ones.

Appearance and distribution

The energy of the earth for heating began to spread in the United States closer to the end of the 80s of the last century in cities that were in serious crisis. The system immediately became interested in wealthy people, to whom it provided an opportunity to save on heating housing. Then it became cheaper, and the poorer class began to apply it.

After some time, the heat of the earth for heating has become the prerogative of the majority of owners of private houses. In Europe, the number of households using the heat of the house with the heat of the earth is increasing every year.

This trend of geothermal heating is quite understandable. Using the heat of the earth for heating can significantly save the family budget, it is safe and economical.

The operation of geothermal heating

Its principle of operation can be compared with a conventional refrigerator, just the opposite. Earth keeps heat constantly, so it is possible to heat objects located on its surface with it.

The meaning of the method is that inside the planet is heated by hot magma, and on top of the ground does not allow it to freeze. The resulting heat energy is used by a geothermal heating system based on a special heat pump.

The following process occurs:

1. Heat pump installed on the surface.
2. A hole is drilled in the ground into which the heat exchanger is lowered..
3. Ground water passing through the pump is heated and then used for domestic and industrial purposes..

The main advantage of the system is the ratio of electrical energy and the received power - 1 to 4-6 kW. For example, when using a conventional air conditioner goes 1 to 1. Therefore, the installation will be able to pay for itself soon.

Special features

Independent heating of a house from the ground has certain difficulties, which we describe below:

1. They begin with the manufacture of the mine shaft. It is calculated separately for each specific case, taking into account:

• climate in the area;
• soil type;
• characteristic of the structure of the earth's crust in the region;
• heating area.

Typically, the depth varies from 25-100 m.

1. At the next stage, pipes are lowered into the barrel, which should absorb heat from the depths and feed it to the pump, which increases the temperature of the heat carrier in the heating system.

Tip: it is better to carry out work with an assistant, as the pipes are often quite large.

In summer, the heating with earth energy can be started as an air conditioner. For which the reverse mechanism is activated. During operation, the heat exchanger will begin to take cooling energy.

Kinds

For an environmentally friendly and efficient system, there are three main options:

Benefits of geothermal heating

Now we will find out what advantages such systems possess, and whether they will be able to satisfy our requests:

1. Heat energy is released several times more than energy consumption for pump operation.
2. There are no harmful emissions, so the heating of a country house from the ground is an environmentally friendly way.
3. The system only needs electricity. The use of chemicals and fuel is not required.
4. During operation there is no danger of explosion or fire.
5. Proper installation of the heating system guarantees operation without technical support for approximately 30 years.

Independent installation of geothermal heating

It must be said at once that the heating of the house with the energy of the earth will require a one-time large investment of funds. The lion's share of which will go to the arrangement of the mine shaft.

Tip: The most expensive part in the heat pump is the compressor. If you do not want problems, do not purchase it from a Chinese factory. It is better to use Danfoss or Copeland (preferably not from China).

We also recommend using a floor heating system instead of radiators. So you can reduce the payback of equipment at times. It is necessary to take into account the annual increase in tariffs for traditional energy sources, at the same time the geothermal heating system at home will avoid price jumps.

Inside the house, nothing will remind you that you are using ground heating. The main part of the scheme - the well and the heat exchanger, will be hidden underground. It is only necessary to allocate a small place for the device, for example, in the basement, which generates heat energy.

The device allows you to adjust the temperature and supply of heat. The installation instructions for the heating system in the house do not differ from the traditional method, so there are no special features in it.

Conclusion

The use of heat pumps makes it possible to get rid of the traditional types of fuel that are rising every year, although the initial costs will be quite large. Installation of geothermal heating is quite possible to carry out independently, only when installing pipes into a shaft, it is advisable to put out an assistant.

The recoupment of the project depends on the insulation of housing, as well as the method of heating - radiator or underfloor heating. Video in the article will provide an opportunity to find additional information on the above topic.
