Ground Loops in Central New Jersey, New Jersey, Geothermal Applications

You’ve just gotten or are mulling over purchasing a a new heating and cooling system. Maybe you’re considering a new Geothermal HVAC. If so, you probably want to know a little more about how geothermal works.

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

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

It works when antifreeze fluid goes through the pipes to move heat quickly and efficiently down to a heat pump in your house.

There exist four different sorts of ground 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 home is determined by the specific building and its surroundings. Household systems usually use vertical or horizontal loops.

Below are further explanations of each sort of ground loop.

Closed systems, which consist of vertical, horizontal, and pond loops, continuously push water through them.

Vertical ground loops are used most often in residences because, unlike horizontal loops, they don’t have to have a significant amount 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 under ground to form the vertical loop. Next, more pipes are attached that carry fluid to the indoor system to transfer the needed temperature from the ground.

In contrast to a vertical loop system, a horizontal system needs much more space but is usually less pricey considering it uses only 2 straight pipes set 6 inches in the ground over an area of ¼ to ¾ acre.

In order to have 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 anchored to the bottom of the water source. Water is then moved through more pipes beneath the earth to a pump, where the heat is extracted and cool water is returned to the pond. That said, 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 adequate 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 home or other structure.

Most often, 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 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 modest change in temperature.

Prior to 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 use up a neighbor’s well source. Be sure to check with your local contractor on whether there’s enough water in the vicinity to justify installing an open loop geothermal heating system.
