Ground Loops in Starkville, Mississippi, 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. If so, you undoubtedly want to know a little bit more about how one works.

Geothermal HVACs take consistent temperature from the ground to put hot or cool air into your home. 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. A few basic sorts of ground loop systems are used for heating and cooling commercial or residential buildings.

The way it works is, antifreeze fluid goes through plastic pipes to move heat fast and efficiently down to a heat pump in your house.

There are four different sorts of geothermal 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 right system for your house is contingent on the specific building and the property on which it sits. Household systems typically 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 push water through them.

Vertical ground loops are used commonly in residences because, unlike horizontal loops, they don’t have to have a lot of space. They’re installed 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, additional pipes are attached that convey 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 is usually not as pricey considering it just uses 2 straight pipes set 6 inches in the earth in an area of ¼ to ¾ acre.

In order to make use of a pond loop system, you obviously 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 underground to a pump, where the heat is pulled out and cool water is reintroduced to the pond. That said, in order for this system to work, the water must not be acidic or else pipes will decay and filters will need replacing often.

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

Normally, used water is disposed off in either of the following ways: through surface drainage or water re-injection. In returning the water back to the earth, it’s worth mentioning that there’s no pollution. The only difference in water that’s processed through a geothermal heat pump is a modest change in temperature.

Before installing an open loop system, it is vital to know whether a well or pond holds enough water to power your geothermal heat pump, and that it won’t deplete a neighbor’s well source. Make certain you check with your local contractor on whether there’s enough water available to warrant installing an open loop geothermal heating system.
