Ground Loops in Greenville, Ohio, Geothermal Applications

It’s time for you to get a new heating and cooling system. Maybe you’re weighing the advantages of a new Geothermal HVAC. If so, you probably want to know a little more about how such a system 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 basically just a series of pipes buried in the earth. Various basic sorts of geothermal loop systems are used for heating and cooling most residential and commercial buildings.

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

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 best system for your house is dependent on the specific building and the property on which it sits. Residential systems usually use vertical or horizontal loops.

Below are further explanations of each sort of ground loop.

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

Vertical ground loops are used typically in residences because, unlike horizontal loops, they don’t take up much of space. They’re positioned 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, extra pipes are attached that channel fluid to the indoor system to transfer the necessary temperature from the ground.

A horizontal system takes up a lot more space but typically doesn’t cost as much because it uses only 2 straight pipes inserted 6 inches in the ground within an area of ¼ to ¾ acre.

If you’re partial to a pond loop system, you plainly 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 conveyed through more pipes underground to a pump, where the heat is extracted and cool water is put back into the pond. However, in order for this system to work, the water can in no way be be acidic or else pipes will corrode and filters will need to be replaced often.

The major difference between open and closed looped systems is the open loop’s need for an ample 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 dwelling or other structure.

There are two ways to dispose of used water: 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. Make certain you check with your local contractor on whether there’s enough water in the vicinity to go ahead with installing an open loop geothermal heating system.
