Geothermal Heating & Cooling | Battle Creek, MI

Geothermal energy originates from the heat retained within the Earth since the original formation of the planet, from radioactive decay of minerals, and from solar energy absorbed at the surface.[2] Most high temperature geothermal heat is harvested in regions close to tectonic plate boundaries where volcanic activity rises close to the surface of the Earth. In these areas, ground and groundwater can be found with temperatures higher than the target temperature of the application. However, even cold ground contains heat, below 10 feet or 3 meters, the ground is consistently 12.8 °C (55 °F) in moderate climates, and it may be extracted with a heat pump.
