Geothermal resource consists of underground layers or springs that contain water with a temperature level which is enough to gain useful forms of energy. Usually, the water is heated through the higher temperatures in the earth core. The water temperate level can be used in the buildings for heating with low temperature directly or with the help of heat pumps. In case of very high temperatures or when the water is in the form of steam, electricity is produced. Here, focus is on the utilization of geothermal resources for heating purposes,......
