Ground Loops in Beatrice, Nebraska, 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. Whatever the circumstances, you probably want to know a little bit more about how geothermal works.

Geothermal HVACs take consistent temperature from the ground to deliver hot or cool air to your home’s interior. This is possible because of an underground system called a geothermal ground loop.

Ground loops are,in essence, just an underground pipe system. A few basic sorts of these systems are used for heating and cooling most residential and commercial buildings.

Antifreeze fluid goes through plastic pipes to move heat effectively and efficiently up to a heat pump in your home.

There exist four different sorts of 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 home is determined by the structure and the property on which it sits. Residential systems typically use vertical or horizontal loops.

Below are further explanations of each type of ground loop.

Closed systems, which encompass 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 need much of space. They’re set in place by drilling tight-diameter holes in the ground that go 100-400 feet deep. Then pipes are driven into the holes and connected under 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 contrast to a vertical loop system, a horizontal system needs significantly more space but is actually not as pricey considering it just uses 2 straight pipes placed 6 inches down in the ground over 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 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 returned to the pond. That said, in order for this system to work, the water must not be acidic or else pipes will erode and filters will need 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, a well or a pond, for example. From there, it directly pumps water into the heat pump unit to be used in heating and cooling your home or other structure.

Generally speaking, 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 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 negligible change in temperature.

Before you install an open loop system, it is essential to know whether a well or pond holds enough water to power your geothermal heat pump, and that it won’t exhaust a neighbor’s well source. See that you check with your local contractor on whether there’s enough water on hand to justify installing an open loop geothermal heating system.
