Ground Loops in Panama City, Florida, Geothermal Applications

You’ve just bought or are thinking about purchasing a a new heating and cooling system. Maybe you’re considering a new Geothermal HVAC. If so, you undoubtedly want to know a little more about how such a system works.

Geothermal HVACs variously cool and heat your home by extracting ground temperature. This can be done because of an underground system called a geothermal ground loop.

Ground loops are pretty much just a system of pipes buried in the ground. Several basic types of geothermal loop systems are used for heating and cooling most residential and commercial buildings.

Antifreeze fluid flows through these plastic pipes to get heat quickly and efficiently to a heat pump in your house.

There are four different kinds of loops: Open Loop, Pond Loop, Horizontal Loop and Vertical Loop. These are divvied up into two categories categories: either they’re open loop systems or closed loop systems. The right system for your home is contingent on the specific structure and the environment surrounding it. Household systems usually use vertical or horizontal loops.

Below are further explanations of each type of ground loop.

Closed systems, which include vertical, horizontal, and pond loops, continuously circulate water through them.

Vertical ground loops are used most often in residences because, unlike horizontal loops, they don’t have to have a significant amount of space. They’re installed by drilling small holes in the ground to a depth of 100-400 feet. Then pipes are inserted into the holes and connected below ground to form the vertical loop. Next, extra pipes are attached that carry fluid to the indoor system to transfer the needed temperature from the ground.

A horizontal loop system has to have a lot more space but usually is less pricey since it uses only 2 straight pipes inserted 6 inches down in the ground in an area of ¼ to ¾ acre.

If you’re thinking of getting a pond loop system, you plainly must be close to a pond, lake, pond, or well. Coils are installed vertically and fastened to the bottom of the water source. Water is then moved through more pipes beneath the earth to a pump, where the heat is extracted and cool water is put back into the pond. Nevertheless, in order for this system to work, the water must not be acidic or else pipes will corrode and filters will need replacing often.

The prime difference between open and closed looped systems is the open loop’s need for an ample source of groundwater, a well or a pond, for example. From there, it directly pumps water into the heat pump unit to be used in heating and cooling your dwelling or other structure.

Used water is taken care of in one of two ways: through surface drainage or water re-injection. In returning the water back to the earth, it is crucial to note that there is no pollution generated. The only difference in water that’s processed through a geothermal heat pump is a slight change in temperature.

Before you install an open loop system, it is essential to know whether a well or pond contains enough water to power your geothermal heat pump, and that it won’t use up a neighbor’s well source. Make sure you check with your local contractor on whether there’s enough water on hand to warrant installing an open loop geothermal heating system.
