Are there different types of geothermal systems?
Yes, there are. In New Hampshire, there are essentially two types of systems, the most common being an “open-loop” system. It consists of one or more groundwater wells and a heat pump. Water is pumped out of the well and circulated through the heat pump where heat is extracted from the water.
