Horizontal Closed Loop
The most common loop design utilizes an excavator to bury the heat exchanger horizontally in the ground approximately 6ft deep.

Open Loop
An abundant supply of high-quality water can be used to operate the heat pump. Water is pulled from a well and discharged into either a pond, stream or another well.

Vertical Closed Loop
This loop allows smaller properties to take advantage of geothermal technology. A drilling rig is used to bury the heat exchanger vertically in the ground.

Pond/Lake Loop
The most cost-effective strategy submerges the heat exchanger in a large body of water (because no digging or drilling is needed). Most homes require a 1/2 acre pond with a ten foot minimum depth for proper operation.
