A Definition of a Thermal Field
A thermal field, or geothermal field, is the space occupied by the installation of a geothermal system.
In a geothermal system, wells are dug in the ground at regular interval. It is the space occupied by these wells that is called a thermal field or a geothermal field. When installing a geothermal system, it is the thermal field that we operate.
The thermal field, or geothermal field, may consist of a variable number of wells, depending on the intensity of energy sought.
