How Geothermal Works
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.
