Ground Loops in Southeast Missouri, Missouri, Geothermal Applications

You’ve got to have a new heating and cooling system. Maybe you’re partial to the idea of a new Geothermal HVAC. Whatever the circumstances, you very likely want to know a bit more about how one works.

Geothermal HVACs take consistent temperature from the ground to put hot or cool air into your home. This works because of an underground system called a geothermal ground loop.

Ground loops are essentially just a series of pipes buried in the earth. There are a few basic types of ground loop systems that can be used for heating and cooling commercial or residential buildings.

The way it works is, antifreeze fluid goes through these plastic pipes to move heat quickly and efficiently down 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 best system for your house is contingent on your building and the environment surrounding it. Home systems mostly use vertical or horizontal loops.

Below are further explanations of each kind of ground loop.

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

Vertical ground loops are used typically in residences because, unlike horizontal loops, they don’t have to have a lot of space. They’re set in place by drilling small holes in the ground to a depth of 100-400 feet. Then pipes are inserted 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 needed temperature from the ground.

In comparison with a vertical loop system, a horizontal system needs significantly more space but actually costs less considering it uses only 2 straight pipes inserted 6 inches down in the ground over an area of ¼ to ¾ acre.

If what you want is 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 Water is then moved through more pipes beneath the earth to a pump, where the heat is withdrawn and cool water is put back into the pond.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 corrode and filters will need to be replaced often.

The essential 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.

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 important to note that there is no pollution generated. The only difference in water that’s processed through a geothermal heat pump is a minor change in temperature.

Before installing an open loop system, it is critical 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 in the vicinity to support installing an open loop geothermal heating system.
