What is Geothermal?
In a heating and cooling sense, the term geothermal describes the process of utilizing the natural heat energy derived from the earth and earth’s groundwater to heat and cool a given space. The earth absorbs nearly 50% of all solar energy and remains at a constant temperature, typically 50°F-54°F, allowing a geothermal unit to easily exchange energy between a home or building and the earth.
Horizontal Ground Closed Loops:
This type is usually the most cost effective when trenches are easy to dig and the size of the yard is adequate. Workers use trenchers or backhoes to dig the trenches three to six feet below the ground in which they lay a series of parallel plastic pipes. They back-fill the trench, taking care not to allow sharp rocks or debris to damage the pipes. Fluid runs through the pipe in a closed system. A typical horizontal loop will be 400 to 600 feet long for each ton of heating and cooling.
