• The Earth's crust is hot. Since the beginning of time, water that has been heated by the high temperature of the earth's crust has been used to heat public baths, greenhouses, and buildings: this is what is traditionally known as geothermal heating. This term is used today in a broader sense to designate the various means of recovering energy from the soil.

• Geothermal heating systems using buried loops offer a new means of using this geothermal energy to heat homes, wherever they are located. Because the energy is recuperated from the top layers of the ground, no deep drilling or heavy investment is required.
