| How to Utilize Geothermal Commercial Energy Systems |
| 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 existing water well or surface water. Regardless of whether the system is open or closed, heat is transferred to or from the structure to provide year-round comfort, no matter what the outdoor temperature is. |
| General Thermal Conductivity Drilling and Testing Procedure: |
 |
Boiler-Cooler Systems
Typically, a boiler is employed to maintain closed loop temperatures above 60°F and a cooling tower to maintain loop temperatures below 90°F. These systems are applicable in medium to large buildings regardless of whether the load is heating or cooling dominated. |
 |
Vertical Loops
The ideal choice when available land surface is limited. Well drilling equipment is used to bore small-diameter holes from 100 to 400 feet deep. |
 |
Pond (Lake) Loops
Very economical to install when a large body of water is available. Coils of pipe are simply placed on the bottom of the pond or lake. |
 |
Ground Water Systems
In ideal conditions, an open-loop application can be the most economical type of geothermal system - utilizing well water, lake, ocean or other water source as a direct energy source. |
