Ground Loops in Topeka, Kansas, Geothermal Applications

You’ve just gotten or are mulling over purchasing a a new heating and cooling system. Maybe you’re considering a new Geothermal HVAC. Whatever the circumstances, you probably want to know a bit more about how geothermal 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 essentially just a system of pipes buried in the ground. Several basic sorts of ground loop systems are used for heating and cooling most residential and commercial buildings.

It works when antifreeze fluid flows through plastic pipes to get heat effectively and efficiently to a heat pump in your home.

There are four different types of loops: Open Loop, Pond Loop, Horizontal Loop and Vertical Loop. These are divvied up into two categories categories: either they’re open loop systems or closed loop systems. The best system for you is determined by your building and its environment. Household systems usually use vertical or horizontal loops.

Below are further explanations of each kind of ground loop.

Closed systems, which consist of 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 small 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, additional pipes are attached that carry fluid to the indoor system to transfer the desired temperature from the ground.

When compared to a vertical loop system a horizontal system requires much more space but is typically less expensive considering it uses only 2 straight pipes inserted 6 inches down in the ground in an area of ¼ to ¾ acre.

If you’re thinking of getting 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 fastened to the bottom of the water source. Water is then conveyed through more pipes underground to a pump, where the heat is drawn out and cool water is reintroduced to the pond. Still, 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 a sufficient source of groundwater, a well or a pond, for instance. From there, it directly pumps water into the heat pump unit for use in heating and cooling your house 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 mentioning that there is no pollution generated. The only difference in water that’s processed through a geothermal heat pump is a modest change in temperature.

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