Ground Loops in Columbus, Ohio, Ohio, Geothermal Applications

You’ve finally gotten, or are contemplating getting, a a new heating and cooling system. Maybe you’re weighing the advantages of a new Geothermal HVAC. Whatever the case, you undoubtedly want to know a little more about how geothermal works.

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

Ground loops are,in essence, just a system of pipes buried in the ground. There are several basic kinds of geothermal loop systems that can be used for heating and cooling commercial or residential buildings.

The way it works is, antifreeze fluid travels through plastic pipes to transfer heat fast and efficiently down to a heat pump in your house.

There 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 you is determined by your building and the environment surrounding it. Home systems usually use vertical or horizontal loops.

Below are additional details on each sort of ground loop.

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

Vertical ground loops are used most often in residences because, unlike horizontal loops, they don’t take up a lot of space. They’re positioned by drilling tight-diameter holes in the ground that extend 100-400 feet deep. Then pipes are placed into the holes and connected below the ground to form the vertical loop. Next, more pipes are attached that carry fluid to the indoor system to transfer the necessary temperature from the ground.

In comparison with a vertical loop system, a horizontal system needs a lot more space but is actually not as pricey because it uses only 2 straight pipes placed 6 inches underground over an area of ¼ to ¾ acre.

If you want a pond loop system, you plainly must be close to a pond, lake, pond, or well. Coils are installed vertically and fastened to the bottom of the water source. Water is then moved through more pipes belowground to a pump, where the heat is pulled 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 corrode and filters will need replacing often.

The big difference between open and closed looped systems is the open loop’s need for an adequate source of groundwater, a well or a pond, for instance. From there, it directly pumps water into the heat pump unit to be used in heating and cooling your house or other structure.

Typically, used water is disposed off in either of the following ways: through surface drainage or water re-injection. In returning the water back to the earth, it must be pointed out that pollution is not a by-product. The only difference in water that’s processed through a geothermal heat pump is a minute change in temperature.

Prior to installing an open loop system, it is vital 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 sure you check with your local contractor on whether there’s enough water in the vicinity to support installing an open loop geothermal heating system.
