Geothermal Loop Configurations

Geothermal systems can be installed with a variety of loop configurations. There are two basic types of geothermal loop configurations: closed and open.

Open loop diagram for geothermal heating and cooling.Open loop systems are the simplest. Water is drawn from one well, passed through the heat pump's exchanger and discharged through a second well.

Closed loop systems are becoming the most common because they are economical, efficient and reliable. Fluids are re-circulated through a continuous loop of buried pipes.

Ask your local dealer for the design that works best with your home.

Horizontal closed loop installations are generally most cost-effective for small installations where sufficient land area is available. These involve burying pipe in trenches dug with back-hoes or chain trenchers.Vertical loop diagram for geothermal heating and cooling systems.

Vertical Loops:

Vertical closed loops are preferred in many situations where the soil is too shallow or land area required is prohibitive. These are installed using a drilling rig.

Pond Loops:
