Ground Loops in Greene County, New York, Geothermal Applications

You’ve finally gotten, or are thinking about getting, a a new heating and cooling system. Maybe you’re weighing the advantages of a new Geothermal HVAC. Whatever the circumstances, you very likely want to know a little bit more about how geothermal 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 series of pipes buried in the earth. Several basic sorts of these systems are used for heating and cooling commercial or residential buildings.

The way it works is, antifreeze fluid flows through the pipes to transfer heat quickly and efficiently up to a heat pump in your home.

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

Below are additional details on each kind of ground loop.

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

Vertical ground loops are used commonly in residences because, unlike horizontal loops, they don’t take up a lot of space. They’re set in place by drilling small-diameter holes in the ground to a depth of 100-400 feet. Then pipes are driven into the holes and connected below ground to form the vertical loop. Next, more pipes are attached that carry fluid to the indoor system to transfer the necessary temperature from the ground.

In contrast to a vertical loop system, a horizontal system needs significantly more space but is typically less costly because it uses only 2 straight pipes placed 6 inches underground within an area of ¼ to ¾ acre.

If you’re thinking of getting a pond loop system, it should be evident that you must be near a pond, lake, pond, or well. Coils are installed vertically and attached to the bottom of the water source. Water is then moved through more pipes beneath the earth to a pump, where the heat is drawn out 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 erode and filters will need replacing often.

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

Used water is disposed 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 modest change in temperature.

Before you install an open loop system, it is vital to know whether a well or pond contains enough water to power your geothermal heat pump, and that it won’t drain a neighbor’s well source. See that you check with your local contractor on whether there’s enough water in the vicinity to go ahead with installing an open loop geothermal heating system.
