1) WORK TO BE DONE:

GEOTHERMAL ENERGY SITUATION IN GALICIA

14

The use of geothermal systems in Galicia, focuses on HVAC systems and thermal

water, using low and very low enthalpy geothermal resource.

Geothermal energy of very low enthalpy, with temperatures of just a few degrees is

available anywhere on our planet, but like any other mining resource its use

depends on the geological conditions of the area where its use is intended. In the

case of the Galicia, the existence of a subsoil with predominance of crystalline

rocks of high thermal conductivity (granites), easily drivable and with a very

shallow water table, makes that practically all its territory is optimal for the

implementation of the Ground Source Heat Pump.
