Ground Loops in Southwest Michigan, Michigan, Geothermal Applications

You’ve got to have a new heating and cooling system. Maybe you’re considering a new Geothermal HVAC. Whatever the situation, you undoubtedly want to know a little bit more about how one works.

Geothermal HVACs take consistent temperature from the ground to put hot or cool air into your home. This works 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 types of geothermal loop systems that can be used for heating and cooling ordinary residential and commercial]26] buildings.

It works when antifreeze fluid flows through the pipes to get heat effectively and efficiently up to a heat pump in the house.

There exist four different kinds of loops: Open Loop, Pond Loop, Horizontal Loop and Vertical Loop. All four fall into one of two categories: either they’re open loop systems or closed loop systems. The appropriate system for your house is determined by the building and the environment surrounding it. Home systems usually use vertical or horizontal loops.

Below are further explanations of each kind of ground loop.

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

Vertical ground loops are used typically in residences because, unlike horizontal loops, they don’t need much of space. They’re positioned by drilling small holes in the ground that extend 100-400 feet deep. Then pipes are driven into the holes and connected below 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.

When compared to a vertical loop system a horizontal system requires much more space but usually is less pricey considering it just uses 2 straight pipes set 6 inches in the ground in an area of ¼ to ¾ acre.

In order to have a pond loop system, you plainly must be near a pond, lake, pond, or well. Coils are installed vertically and affixed 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 Water is then transported through more pipes beneath the earth to a pump, where the heat is withdrawn and cool water is returned to the pond.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 a sufficient 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 house or other structure.

Used water is disposed of in one of two 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 essential 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. Be sure to check with your local contractor on whether there’s enough water in the vicinity to support installing an open loop geothermal heating system.
