Ground Loops in Hattiesburg, Mississippi, Geothermal Applications

You’ve just gotten or are mulling over 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 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,in essence, just a series of pipes buried in the earth. There are various basic types of these systems that can be used for heating and cooling ordinary residential and commercial]26] buildings.

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

There are four different sorts of 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 best 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 further explanations of each sort of ground loop.

Closed systems, which consist of 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 a lot of space. They’re positioned by drilling tight-diameter holes in the ground that extend 100-400 feet deep. 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.

A horizontal system takes up significantly more space but is generally not as costly since it uses only 2 straight pipes set 6 inches in the earth in an area of ¼ to ¾ acre.

If you’re partial to a pond loop system, you plainly must be close to a pond, lake, pond, or well. Coils are installed vertically and
secured 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. That said, in order for this system to work, the water can not be acidic or else pipes will corrode and filters will need replacing 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 house 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’s worth noting that there’s no pollution. 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 contains 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 available to go ahead with installing an open loop geothermal heating system.
