Geothermal Heating Systems

Geothermal heat pumps strengthen US energy security. Every 100,000 homes with geothermal heat pump systems reduce foreign oil consumption by 2.15 million barrels annually and reduce electricity consumption by 799 million kilowatt hours annually.

\"We are very happy with our geothermal unit. It has exceeded our expectations...with the rise in gas prices, the unit will be paid for in 4 years based on propane savings alone. Installation was fast and professional. Our unit is essentially maintenance free and the Haley\\\'s professional staff has always been more than willing to answer any questions that I have had regarding my system.\"

\"Bridget, I just wanted to let you know how impressed I was with the Haley team during my Geothermal System installation. The installation itself was like clock work and went incredibly smooth. I also appreciated the fact that the crew cleaned up well everyday and when I had questions the team made me feel like I was the most important person on their list. I just wanted to thank Haley Comfort Systems for installing a system that, on average, only costs me $336 per year. What tremendous savings!!!\"

Today there are now more than 1,000,000 geoexchange installations in the United States.


These 1,000,000 installations have also resulted in the following energy consumption reductions:

Annual savings of nearly 8 billion kWh

Annual savings of nearly 40 trillion Btus of fossil fuels

Reduced electricity demand by more than 2.6 million kW


The monumental impact of the current use of geoexchange is equivalent to:

Taking close to 1,295,000 cars off the road

Planting more than 385 million trees

Reducing US reliance on imported fuels by 21.5 million barrels of crude oil
per year


Types of Geothermal Loops

Vertical Loop
Used mainly when land area is limited. A drilling rig is used to bore holes to depths of approximately 125 to 250 feet deep. A U-shaped loop of high-density polyethylene pipe is inserted. The holes are then backfilled with a sealing solution.

Horizontal Loop
Used when adequate land is available. Loop installers use a chain trencher or backhoe to dig trenches. Each trench is approximately 6 feet deep. Trench lengths range from 100 to 300 feet. Depending on loop design and application.

Pond Loop
Option available if a large body of water is present. A 1/2 acre, 8 foot deep body of water is usually sufficient for the average home. This system places coiled pipe on the bottom of the body of water.

Open Loop
This system can be installed if an abundant supply of well water is available. A proper discharge site, such as a ditch, field tile, stream, or pond must also be present. Check your local codes before selecting a discharge method.
