Ground Loops in Beckley, West Virginia, Geothermal Applications

You’ve finally gotten, or are thinking about getting, a a new heating and cooling system. Maybe you’re partial to the idea of a new Geothermal HVAC. Whatever the case, you undoubtedly want to know a bit more about how such a system 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 pretty much just an underground pipe system. Various basic kinds of ground loop systems are used for heating and cooling common residential and commercial]26] buildings.

Antifreeze fluid flows through these plastic pipes to get heat effectively and efficiently up to a heat pump in your 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 home is contingent on your building and the property on which it sits. Household systems usually use vertical or horizontal loops.

Below are further explanations of each type of ground loop.

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

Vertical ground loops are the most common type used residentially because, unlike horizontal loops, they don’t require a lot of space. They’re installed by drilling small-diameter holes in the ground that extend 100-400 feet deep. Then pipes are driven into the holes and connected below ground to form the vertical loop. Next, additional 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 requires significantly more space but is typically not as costly because it uses only 2 straight pipes placed 6 inches down in the ground within an area of ¼ to ¾ acre.

If you’re partial to a pond loop system, it should go without saying that you must be in close proximity 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 reintroduced to the pond. That said, in order for this system to work, the water can not be acidic or else pipes will decay and filters will have to be replaced often.

The major difference between open and closed looped systems is the open loop’s need for a plentiful source of groundwater, like 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.

Normally, used water is taken care off in either of these 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 slight change in temperature.

Before you install an open loop system, it is critical to know whether a well or pond has enough water to power your geothermal heat pump, and that it won’t use up a neighbor’s well source. See that you check with your local contractor on whether there’s enough water in the vicinity to warrant installing an open loop geothermal heating system.
