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

Geothermal HVACs variously cool and heat your home by extracting ground temperature. This works because of an underground system called a geothermal ground loop.

Ground loops are basically just an underground pipe system. There are several basic sorts of geothermal loop systems that can be used for heating and cooling commercial or residential buildings.

The way it works is, antifreeze fluid goes through the pipes to get heat fast and efficiently to a heat pump in the building.

There are four different kinds 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 appropriate system for you is determined by the structure and the property on which it sits. Home 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 circulate 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 set in place by drilling tight-diameter holes in the ground to a depth of 100-400 feet. Then pipes are driven into the holes and connected below the ground to form the vertical loop. Next, more pipes are attached that convey fluid to the indoor system to transfer the desired temperature from the ground.

In comparison with a vertical loop system, a horizontal system needs much more space but is usually not as pricey because it just uses 2 straight pipes set 6 inches in the earth within an area of ¼ to ¾ acre.

In order to make use of a pond loop system, you obviously must be close 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 beneath the earth to a pump, where the heat is drawn out and cool water is put back into the pond. Nevertheless, 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, 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 take care of used water: through surface drainage or water re-injection. In returning the water back to the earth, it is crucial 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 you install an open loop system, it is critical to know whether a well or pond contains enough water to power your geothermal heat pump, and that it won’t use up a neighbor’s well source. Make sure you check with your local contractor on whether there’s enough water on hand to justify installing an open loop geothermal heating system.
