Question by jarrod s: how does geothermal heating and cooling work, in a nut shell?
Answer by Ryan14
Geothermal heating has been used since Roman times as a way of heating buildings and spas by utilizing sources of hot water and hot steam that exist near the earth’s surface. Where such geothermal resources are available, it is possible to distribute hot water or steam to multiple buildings.
Not the best answer, but it’s basically heat used from the ground.
