Ground Loops in Hattiesburg, Mississippi, Geothermal Applications

You’ve finally gotten, or are contemplating getting, a a new heating and cooling system. Maybe you’re partial to the idea of a new Geothermal HVAC. If so, you very likely want to know a little 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 series of pipes buried in the earth. There are several basic types of these systems that can be used for heating and cooling commercial or residential buildings.

It works when antifreeze fluid travels through these plastic pipes to get heat effectively and efficiently down to a heat pump in the building.

There are four different sorts of geothermal ground loops: Open Loop, Pond Loop, Horizontal Loop and Vertical Loop. All four are split into two distinct categories: either they’re open loop systems or closed loop systems. The right system for your house is contingent on the specific structure and the environment surrounding it. Household systems typically use vertical or horizontal loops.

Below are more specifics on each sort of ground loop.

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

Vertical ground loops are the most common type used residentially because, unlike horizontal loops, they don’t need much of space. They’re positioned by drilling small holes in the ground to a depth of 100-400 feet. Then pipes are placed into the holes and connected below ground to form the vertical loop. Next, extra pipes are attached that channel fluid to the indoor system to transfer the necessary temperature from the ground.

When compared to a vertical loop system a horizontal system needs significantly more space but generally is less pricey since it uses only 2 straight pipes placed 6 inches in the ground over an area of ¼ to ¾ acre.

In order to make use of a pond loop system, you plainly must be near a pond, lake, pond, or well. Coils are installed vertically and anchored to the bottom of the water source. Water is then conveyed through more pipes beneath the earth to a pump, where the heat is extracted and cool water is reintroduced to the pond. Still, in order for this system to work, the water can never be be acidic or else pipes will erode and filters will need to be replaced often.

The big difference between open and closed looped systems is the open loop’s need for an ample 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.

There are two ways to dispose of used water: through surface drainage or water re-injection. In returning the water back to the earth, it’s worth noting 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.

Prior to installing 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. Be sure to check with your local contractor on whether there’s enough water in the vicinity to warrant installing an open loop geothermal heating system.
