Energy 101: Geothermal Heat Pumps

The following edit was recommended by DOE's Office of Energy Efficiency and Renewable Energy's Geothermal Technologies Office: At :58, “During the winter, the air is usually cooler than the temperature below ground. The solution circulates in a loop underground and absorbs the Earth's heat. This heat is brought to the surface and transferred to a heat pump. T̶h̶e̶ ̶h̶e̶a̶t̶ ̶p̶u̶m̶p̶ ̶w̶a̶r̶m̶s̶ ̶t̶h̶e̶ ̶a̶i̶r̶ ̶a̶n̶d̶ ̶y̶o̶u̶r̶ ̶r̶e̶g̶u̶l̶a̶r̶ ̶h̶e̶a̶t̶i̶n̶g̶ ̶s̶y̶s̶t̶e̶m̶ ̶w̶a̶r̶m̶s̶ ̶t̶h̶e̶ ̶a̶i̶r̶ ̶s̶o̶m̶e̶ ̶m̶o̶r̶e̶ ̶t̶o̶ ̶a̶ ̶c̶o̶m̶f̶o̶r̶t̶a̶b̶l̶e̶ ̶t̶e̶m̶p̶e̶r̶a̶t̶u̶r̶e̶.̶ ̶F̶i̶n̶a̶l̶l̶y̶ Ducts circulate the air to the various rooms.” --- An energy-efficient heating and cooling alternative, the geothermal heat pump system moves heat from the ground to a building (or from a building to the ground) through a series of flexible pipe "loops" containing water.
