Thermal waters (1) in a temperature range from 100 °C up to 250 °C (212°F- 482°F) that rise to the surface from hot water aquifers (aquifer = ground or mineral water containing layer of earth) or after the Hot-Dry-Rock principle flow through an evaporator (2). This evaporator has to be made from special, salt resistant metal alloys because of the high content of salt and solute gases in the thermal water. The water is cooled down to approximately 80 °C (176°F) and then is reinjected into the drill hole (3). The residual heat can be used for heating purposes
