Ground Loops in New Jersey, New Jersey, Geothermal Applications

You’ve finally gotten, or are considering getting, a a new heating and cooling system. Maybe you’re weighing the advantages of a new Geothermal HVAC. Whatever the circumstances, you undoubtedly want to know a bit more about how one 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,in essence, just a system of pipes buried in the ground. There are a few basic types of these systems that can be used for heating and cooling common residential and commercial]26] buildings.

It works when antifreeze fluid goes through these plastic pipes to transfer heat quickly and efficiently up to a heat pump in the house.

Typically used are four different sorts of ground loops: Open Loop, Pond Loop, Horizontal Loop and Vertical Loop. These fall into one of two different categories: either they’re open loop systems or closed loop systems. The appropriate system for your house is dependent on your building and the environment surrounding it. Household systems mostly use vertical or horizontal loops.

Below are additional details on each kind of ground loop.

Closed systems, which consist of vertical, horizontal, and pond loops, continuously move water through them.

Vertical ground loops are used commonly in residences because, unlike horizontal loops, they don’t have to have much of space. They’re positioned by drilling small 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, additional pipes are attached that channel fluid to the indoor system to transfer the necessary temperature from the ground.

In comparison with a vertical loop system, a horizontal system needs much more space but is actually not as expensive because it uses 2 straight pipes inserted 6 inches underground in an area of ¼ to ¾ acre.

In order to have a pond loop system, it should be evident that you must be in close proximity to a pond, lake, pond, or well. Coils are installed vertically and affixed to the bottom of the water source. Water is then transferred through more pipes belowground to a pump, where the heat is pulled out and cool water is put back into the pond. Nevertheless, in order for this system to work, the water can never be be acidic or else pipes will decay and filters will have to be replaced often.

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

Generally speaking, used water is taken care off in either of these ways: through surface drainage or water re-injection. In returning the water back to the earth, it must be said that pollution is not a by-product. The only difference in water that’s processed through a geothermal heat pump is a negligible change in temperature.

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