What is geothermal home energy?

Geothermal home, more properly called low enthalpy geothermal energy, is the technology that allows you to heat and cool a room by exploiting the temperature difference between the outer layers of the Earth's crust and the external environment. This technology involves the exploitation of ground water and is suitable for a wide range of construction and any geographical location.

The low enthalpy geothermal energy can be installed in place of traditional heating systems, when combined with a thermal buonisolamento and maybe even a radiant heating system, offers significant economic and environmental benefits. Not actually represents a real technological breakthrough in fact in the countries of Northern Europe is widely exploited for over 30 years.

The fundamental principle of this technology is precisely the heat exchange that occurs with the ground or with the rocks. During the winter season, in fact, the environment is heated by the transfer of heat from the ground to the user while in the summer the heat is transferred from the environment to the ground.

Geothermal plants can be divided into two main technologies:

the borehole heat exchangers (tubes) vertical heat with depths ranging from 50 to over 200 m. Plant coil, heat exchangers placed horizontally at 1-2 m depth in loose soil.

The costs for this technology are quite competitive with other renewable sources, it is estimated that for a house of 150 square meters the cost is estimated to be around 20,000 euros. In addition, the 2008 Budget provides a 55% tax deduction on expenditure incurred for the replacement of a traditional heating system with a geothermal system.
