Geothermal heat, also known as ground source heat, pumps heat from deep within the ground that was generated by the earth’s core. This efficient technology can be used for both heating and cooling, and works by transferring the air stored within the ground into a home or business, and sending the warmer or cooler air from the building back into the ground. Geothermal heat pumps reduce electricity consumption and also improve indoor humidity control. Geothermal heat is a viable option for Minneapolis homes and businesses and an innovative component of many green building projects.
