Closed-Loop Geothermal Systems (Horizontal and Vertical)

Closed-loop geothermal systems usually circulate a heat-transfer fluid, typically a food-grade antifreeze, through pipes or coils buried beneath the land surface. During the winter, the fluid collects heat from the earth wmf during summer, the systems cools the building by pulling heat from the building, carrying it through the system, and leaving it in the ground.

The closed-loop geothermal systems can be installed horizontally or vertically beneath the land surface, or in the bed of a body of water. Horizontal geothermal systems require more land (enough to dig a 100 to 300-foot trench), but a vertical system requires numerous well holes drilled deep enough vertically to accommodate the geothermal loops or plates.

Pond Loop Geothermal Systems

If your home or commercial building is near a body of water, such as a pond or a lake, this type of geothermal loop design may be the most economical. The fluid circulates through polyethylene piping in a closed system, just as it does with a in the ground loop, but typically, workers run the pipe to the water, then submerge long sections under water.

Geothermal heating and cooling experts recommend using a pond loop only if the water level never drops below six to eight feet at its lowest to assure sufficient heat-transfer capability.

Pond loops used in a closed system result in no adverse impacts on the aquatic system.

Open-Loop Geothermal Systems

Open-loop geothermal systems operate on the same principle as closed-loop systems, but typically use ground water as the heat-exchange fluid. After it circulates through the system, the water is discharged over land or directly into lakes, wetlands, streams or ditches.

Permit Requirements

The Department of Natural Resources requires a water appropriation permit if the total water use from a supply well, including the geothermal system and other uses, is more than 10,000 gallons per day or more than 1 million gallons per year. For open loop systems the discharge of water may require a permit from the Minnesota Pollution Control Agency and possibly from a local government unit.
