Do you know that you can heat or cool your home using the warmth of the earth? The principle of geothermal air conditioning is very simple:
Βased on the fact that few meters below the surface temperature of the soil is standard at 18-20 degrees Celsius. If we, therefore, seize the temperature difference between surface and underground, you can warm places in winter and the cool in the summer. This is done by using a geothermal heat pump and the heat transmitted through a network of pipes that are either in a horizontal or vertical layout.
A geothermal heat pump saves approximately 25-30% of energy, thus contributing significantly to energy savings and a cleaner environment.
Geothermal heat pumps can also be used in hybrid systems, along with solar thermal.
