Ground Loops in Lancaster, Pennsylvania, Geothermal Applications

You’ve got to have a new heating and cooling system. Maybe you’re weighing the advantages of a new Geothermal HVAC. Whatever the circumstances, you very likely want to know a little bit more about how geothermal 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 essentially just a series of pipes buried in the earth. A few basic sorts of these systems are used for heating and cooling typical residential and commercial]26] buildings.

It works when antifreeze fluid flows through these plastic pipes to transfer heat quickly and efficiently to a heat pump in your home.

Typically used are four different types of 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 appropriate system for your house is determined by the structure and its environment. Home systems mostly 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 push 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 installed by drilling tight-diameter holes in the ground that extend 100-400 feet deep. Then pipes are driven into the holes and connected below the ground to form the vertical loop. Next, extra pipes are attached that convey fluid to the indoor system to transfer the necessary temperature from the ground.

A horizontal loop system has to have a lot more space but is typically less costly because it uses 2 straight pipes set 6 inches in the earth within an area of ¼ to ¾ acre.

If you’re thinking of getting a pond loop system, it should be evident 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 belowground to a pump, where the heat is extracted and cool water is put back into the pond. However, in order for this system to work, the water can in no way be be acidic or else pipes will decay and filters will need replacing often.

The big difference between open and closed looped systems is the open loop’s need for a sufficient source of groundwater, like 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.

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 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 an insignificant 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 deplete a neighbor’s well source. See that you check with your local contractor on whether there’s enough water on hand to justify installing an open loop geothermal heating system.
