Ground Loops in Central Ohio, Ohio, Geothermal Applications

It’s time for you to get a new heating and cooling system. Maybe you’re partial to the idea of a new Geothermal HVAC. If so, you probably want to know a little bit more about how one 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 basically just a system of pipes buried in the ground. Several basic sorts of these systems are used for heating and cooling standard 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 the building.

There exist four different types 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 right system for your home is dependent on your building and the property on which it sits. Household systems usually use vertical or horizontal loops.

Below are additional details on 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 commonly in residences because, unlike horizontal loops, they don’t need a significant amount of space. They’re installed by drilling small holes in the ground that go 100-400 feet deep. Then pipes are driven into the holes and connected below ground to form the vertical loop. Next, additional pipes are attached that channel fluid to the indoor system to transfer the desired temperature from the ground.

In comparison with a vertical loop system, a horizontal system needs much more space but actually doesn’t cost as much since it uses only 2 straight pipes inserted 6 inches underground over an area of ¼ to ¾ acre.

If you’re thinking of getting a pond loop system, it should go without saying that you must be near a pond, lake, pond, or well. Coils are installed vertically and
secured to the bottom of the water source. Water is then transferred through more pipes underground to a pump, where the heat is drawn out and cool water is put back into the pond. Nevertheless, 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 to be replaced often.

The primary difference between open and closed looped systems is the open loop’s need for an adequate 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.

Typically, 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 minor change in temperature.

Prior to installing an open loop system, it is vital to know whether a well or pond holds enough water to power your geothermal heat pump, and that it won’t use up 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.
