Ground Loops in Dexter, Michigan, Geothermal Applications

You’ve just purchased or are mulling over 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 bit more about how geothermal works.

Geothermal HVACs take consistent temperature from the ground to put hot or cool air into your home. This can be done because of an underground system called a geothermal ground loop.

Ground loops are pretty much just an underground pipe system. There are several basic sorts of geothermal loop systems that can be used for heating and cooling conventional residential and commercial]26] buildings.

Antifreeze fluid travels through the pipes to get heat quickly and efficiently down to a heat pump in your home.

There exist 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 appropriate system for you is determined by your structure and its surroundings. Residential systems primarily 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 move water through them.

Vertical ground loops are the most common type used residentially because, unlike horizontal loops, they don’t require a significant amount of space. They’re set in place by drilling small 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, more pipes are attached that convey fluid to the indoor system to transfer the desired temperature from the ground.

A horizontal loop system has to have a lot more space but generally doesn’t cost as much because it uses 2 straight pipes set 6 inches in the earth over an area of ¼ to ¾ acre.

If what you want is a pond loop system, you plainly must be close to a pond, lake, pond, or well. Coils are installed vertically and
secured to the bottom of the water source. Water is then transported through more pipes belowground to a pump, where the heat is extracted and cool water is put back into the pond. Nevertheless, in order for this system to work, the water can not be acidic or else pipes will erode and filters will need to be replaced often.

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

Used water is taken care of in one of two 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 slight change in temperature.

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