Geothermal heat pumps connect to a ground loop system that transfers heat to and from your home. There are a number of different ground loop systems, all of which are designed differently to meet your needs and the land characteristics.
The question often asked is, “Which loop works the best?” The answer: all of them. Each type of loop, when designed properly, can yield equal effectiveness to the geothermal heat pump system. Depending on the type of land and how much space is available will dictate which loop system is best.

Types of Geothermal Ground Loops Systems
Open Loop System – Uses well water as the heat exchange fluid that circulates directly through the heat pump system.
Closed Loop System – Circulates a water and antifreeze solution through the geothermal pipes, carrying heat to a heat exchanger.
Standing Column Well System – Uses a well to circulate water between the ground and the geothermal heat pump to heat and cool your home more efficiently.
Vertical Loop System – Used when there is not enough property for trenching, minimizing the disturbance to the existing landscaping.
Horizonal Loop System – Generally most cost-effective for residential installations, where sufficient land is available for trenches at least 4 feet deep.
Pond or Lake System – For sites with an adequate body of water: at least .5 acre with a minimum depth of 8 feet.
Horizontal Bored System – Commonly utilized in the running of natural gas lines, fiber optic, or utility cables, it is the least invasive and reliable way to install geothermal pipes.
