Ground Loops in Hart, Michigan, Geothermal Applications

You need a new heating and cooling system. Maybe you’re partial to the idea of a new Geothermal HVAC. Whatever the situation, you undoubtedly want to know a little more about how one 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 essentially just a system of pipes buried in the ground. There are several basic types of these systems that can be 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 the house.

Typically used are four different sorts of geothermal ground 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 your house is contingent on the specific building and its environment. Home systems mostly 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 push water through them.

Vertical ground loops are used commonly in residences because, unlike horizontal loops, they don’t take up much of space. They’re set in place 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, additional pipes are attached that convey fluid to the indoor system to transfer the needed temperature from the ground.

When compared to a vertical loop system a horizontal system requires a lot more space but usually costs less considering it uses only 2 straight pipes placed 6 inches down in the ground within an area of ¼ to ¾ acre.

If you want a pond loop system, you plainly must be near a pond, lake, pond, or well. Coils are installed vertically and anchored to the bottom of the water source. Water is then transported through more pipes beneath the earth to a pump, where the heat is withdrawn and cool water is returned to the pond. That said, in order for this system to work, the water must not be acidic or else pipes will corrode and filters will have 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, a well or a pond, for example. From there, it directly pumps water into the heat pump unit to be used in heating and cooling your home or other structure.

Generally speaking, 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 said that pollution is not a by-product. The only difference in water that’s processed through a geothermal heat pump is an insignificant change in temperature.

Before installing 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 drain a neighbor’s well source. See that you check with your local contractor on whether there’s enough water available to warrant installing an open loop geothermal heating system.
