Ground Loops in Ebensburg, Pennsylvania, Geothermal Applications

You need a new heating and cooling system. Maybe you’re partial to the idea of a new Geothermal HVAC. Whatever the case, you undoubtedly want to know a little more about how geothermal works.

Geothermal HVACs variously cool and heat your home by extracting ground temperature. This works because of an underground system called a geothermal ground loop.

Ground loops are pretty much just a system of pipes buried in the ground. There are several basic kinds of geothermal loop systems that can be used for heating and cooling ordinary residential and commercial]26] buildings.

It works when antifreeze fluid travels through plastic pipes to move heat effectively and efficiently to a heat pump in your house.

Typically used are four different sorts of loops: Open Loop, Pond Loop, Horizontal Loop and Vertical Loop. All four are split into two distinct categories: either they’re open loop systems or closed loop systems. The right system for your home is contingent on the building and its surroundings. Residential systems mostly use vertical or horizontal loops.

Below are further explanations of each kind of ground loop.

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

Vertical ground loops are used commonly in residences because, unlike horizontal loops, they don’t have to have much of space. They’re installed by drilling tight-diameter holes in the ground to a depth of 100-400 feet. Then pipes are inserted into the holes and connected under ground to form the vertical loop. Next, additional pipes are attached that carry fluid to the indoor system to transfer the necessary temperature from the ground.

A horizontal system takes up a lot more space but typically costs less considering it uses 2 straight pipes set 6 inches in the earth within an area of ¼ to ¾ acre.

In order to install a pond loop system, you obviously must be near a pond, lake, pond, or well. Coils are installed vertically and attached to the bottom of the water source. Water is then transferred through more pipes underground 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 replacing often.

The prime 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 disposed of in one of two ways: through surface drainage or water re-injection. In returning the water back to the earth, it is crucial to note that there is no pollution generated. The only difference in water that’s processed through a geothermal heat pump is a negligible change in temperature.

Before installing 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 available to warrant installing an open loop geothermal heating system.
