Three 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 are installed horizontally, vertically, or in a pond.

Horizontal Loop

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

Vertical Loops

This is 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

Pond & Lake Loops

Choose this loop because it is very economical to install when a large body of water is available for use by the geothermal heating and cooling system. Coils of pipe are simply placed on the bottom of the pond or lake to capture the geothermal energy.

Open Loops (Wel Water Systems)

In ideal conditions, an open-loop application can be the most economical type of geothermal system. These use groundwater from a well as a direct energy source.
