The modern ecological tendencies on the one hand, and the continuously increasing cost of conventional forms of energy on the other hand, is one way track to use renewable forms of energy even on daily applications issues like heating and air conditioning of a residence. One of the forms of energy that belongs to this category, the renewable forms of energy is geothermal energy.

With the term geothermal energy we mean the energy that is contained in the ground interior and it is so big, that can be considered practically inexhaustible for the human facts.

The principle of geothermal energy is exceptionally simple and it is based on the fact that few metres under the surface of the ground the ground temperature is constant at 14-20°C at any given time. If consequently we exploit the difference of temperature between subsoil and surface, we can heat spaces in the winter and freeze them respectively during summertime.

This can be achieved with the use of geothermal pump of heat, while the heat is transmitted through a network of pipes with water, that or is found in horizontal provision and low depth, or in vertical provision exploiting one or more drillings that become for this reason.

A geothermal heat pump consumes usually round 25-30% of the energy that it attributes.

Thus the users of geothermal energy can receive until 75% of the required heat, free of charge from the ground.

Moreover the use of geothermal energy ensures the following advantages:

• It is available on a 24-hour basis, at any given time and under any weather conditions (It does not depend e.g. on the sunlight etc).
• It is permanently renewable, while it emanates from the interior of the ground and the radiation of helium.
• It can be developed with tried refrigeration-heating technologies, as an example surface heating or air conditioning with fan coils, as well as in hybrid systems, as e.g. joint with solar heated fields.
• It ensures heating and refrigeration of spaces as well as production of hot water of use with the same installation without extra cost.
• It is completely independent on oil.
• It saves room, for reservoir of oil and chimney
• It is friendly to the environment since there is no need of emissions of pollutants.
