Ground Loops in Fort Wayne, Indiana, 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. If so, 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 can be done because of an underground system called a geothermal ground loop.

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

Antifreeze fluid flows through these plastic pipes to transfer heat effectively and efficiently up to a heat pump in the house.

There are four different sorts 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 appropriate system for you is contingent on the specific building and the environment surrounding it. Residential systems primarily use vertical or horizontal loops.

Below are more specifics on each sort of ground loop.

Closed systems, which encompass vertical, horizontal, and pond loops, continuously move water through them.

Vertical ground loops are the most common type used residentially because, unlike horizontal loops, they don’t need a significant amount of space. They’re installed 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 the ground to form the vertical loop. Next, additional pipes are attached that convey 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 usually less expensive because it uses only 2 straight pipes set 6 inches in the ground in an area of ¼ to ¾ acre.

If you’re thinking of getting 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 Water is then transferred through more pipes underground to a pump, where the heat is withdrawn and cool water is returned to the pond. Still, 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 replacing often.

The prime difference between open and closed looped systems is the open loop’s need for an adequate source of groundwater, such as 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.

Normally, 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’s worth noting that there’s no pollution. The only difference in water that’s processed through a geothermal heat pump is a minor change in temperature.

Before installing an open loop system, it is vital 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 support installing an open loop geothermal heating system.
