Geothermal Pond Heating and Cooling Loop
What is a Geothermal Pond or Lake Heat Pump Loop
A pond loop is a great option for a Geothermal Heat Pump system installation when a large body of water is available near the home or business. This loop system would be the most economical because these loops often require less excavation than vertical and horizontal loops.  Coils of pipe are simply placed on the bottom of the pond or lake to capture the geothermal energy. Hoffman Brothers Heating & Air Conditioning, your St Louis Premier Geothermal heating and cooling installation company, has the skilled technicians available to install your geothermal pond loop.

Benefits of a Geothermal Energy Pond or Lake Loop
Ponds and lakes are excellent applications for geothermal systems since water provides superb heat transfer to or from the pipe. In the cold St Louis, MO winters, ice can form on the surface of the pond or lake, but the temperature at the bottom of the pond remains relatively constant and unfrozen providing an abundant supply of geothermal heat.
When to use a Geothermal Pond/Lake Loop Installation
A half acre, 8 to 10 foot deep body of water is usually adequate to support the average home. The body of water is best if it is within 200 feet from the home. This geothermal system uses coils of pipe typically 300 to 500 feet in length. The coils are placed in and anchored at the bottom of the body of water. Polyethylene piping is run to the water underground and then long sections are submerged under water. The pipe may be coiled in a slinky shape to fit more of it into a given amount of space. The fluid circulates through the piping, just as it does in ground loops, to the geothermal unit. Pond loops used in a closed system result in no adverse impacts on the aquatic system.
