Geothermal systems are technological systems that make it possible to exploit the earth’s heat to heat/cool rooms and for the production of hot water for domestic and industrial use. The earth’s heat is drawn by the heat-transfer fluid that circulates inside geothermal probes and is transferred to a suitable heat pump that brings the extracted heat to the required temperature and puts it into the heating circuits.

The geothermal probes, i.e. pipes placed inside the ground, can be of the following types:

  • horizontal, i.e. pipes installed horizontally over a broad surface area at a depth of approximately 1.50 metres;
  • vertical, i.e. pipes installed vertically at a depth normally between 70 and 150 metres.

The type of system to be installed depends on the stratigraphy of the ground, on the dimensions of the available surfaces, on the performance objectives that we wish to achieve and on other project-related aspects.

Exploiting the earth’s heat offers an economic source of energy that does not depend on the atmospheric conditions and seasons, continuously renewed by the earth’s heat and sunlight. This solution is distinguished by a low environmental impact (lower CO2 emissions) and by energy savings (up to 75% for heating and cooling).
