Geothermal Heating and Cooling

 

No matter what climate you live in, the temperature throughout the year varies. For some climates that means blazing summers that cool to frigid winters. What many people don’t realize is that the temperature below ground (regardless of climate or season) stays fairly consistent all year.

The ground absorbs 47% of the sun’s energy as it hits the Earth’s surface – this is how the ground is able to hold a consistent temperature. Whether you’re in chilly Seattle or balmy Miami, the temperature just below the frost line stays relatively consistent. GeoStar geothermal systems tap into this free energy with an earth loop, which is where it all begins.

 

 

 

 

Four Basic Geothermal Energy Sources

  • Closed-loop systems circulate a water-based solution through a “loop system ” of small-diameter, high-density polyethylene underground pipes. Closed-loop systems can be installed horizontally, vertically or in a pond. Open-loop systems use an existing water well or surface water. Whether the system is open or closed, heat is transferred to or from the structure, regardless of outdoor temperature, to provide year-round comfort.

    Horizontal Loops

    Often used when adequate land surface is available. Depending on geothermal system needs and space available, pipes are placed in trenches that range in length from 100 to 400 feet.

    Vertical Loops

    The ideal choice for a geothermal heat pump when available land surface is limited. Well drilling equipment is used to bore small-diameter holes from 100 to 400 feet deep.
