The GeoThermal System’s Indoor Portion: What It Involves
A geothermal heating and cooling system consists of an indoor and an outdoor portion, both of which are vital to the system’s function. The basic structure of a water-source geothermal system requires an outdoor system of pipes, often referred to as the water loop, placed in a well, aquifer, lake or other water source at a depth where the water retains a consistent year-round temperature. Ground-source heat pumps use a similar loop system buried at a distance beneath the surface where the temperature stays about 50 degrees all year long.
