Geothermal installations come in two ways. One is smaller and simpler in nature, also known as ‘Direct Use’, where tubes are drilled down to the water table to tap hot water that is used in homes and offices. In some cases, pumps are used to pull the hot water that is used to warm power air heating systems in colder climates. This kind of geothermal delivery accounts for about 70% of its use, whiles about 30% accounts for it use as electricity.
