How Does Geothermal Heat System Work

Geothermal heat originates from Earth’s fiery consolidation of dust and gas over 4 billion years ago. At earth’s core – 4,000 miles deep – temperatures may reach over 9,000 degrees F.
Today we drill wells into the geothermal reservoirs to bring the hot water to the surface. Geologists, geochemists, drillers and engineers do a lot of exploring and testing to locate underground areas that contain this geothermal water, so we’ll know where to drill geothermal production wells.
