Ground Loops in Medina, Ohio, Geothermal Applications

You’ve finally gotten, or are considering getting, a a new heating and cooling system. Maybe you’re partial to the idea of a new Geothermal HVAC. If so, you undoubtedly want to know a little more about how one 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 essentially just an underground pipe system. Several basic kinds of geothermal loop systems are used for heating and cooling conventional residential and commercial]26] buildings.

Antifreeze fluid goes through these plastic pipes to get heat effectively and efficiently to a heat pump in your house.

There exist four different sorts 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 right system for your home is dependent on the specific structure and its environment. Household systems mostly use vertical or horizontal loops.

Below are additional details on each type of ground loop.

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

Vertical ground loops are used most often in residences because, unlike horizontal loops, they don’t have to have a lot of space. They’re set in place by drilling small-diameter holes in the ground to a depth of 100-400 feet. Then pipes are driven into the holes and connected below the ground to form the vertical loop. Next, additional pipes are attached that carry fluid to the indoor system to transfer the desired 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 uses only 2 straight pipes set 6 inches underground within an area of ¼ to ¾ acre.

If you want a pond loop system, it should be evident that you must be near a pond, lake, pond, or well. Coils are installed vertically and anchored to the bottom of the water source. Water is then transported through more pipes belowground to a pump, where the heat is extracted and cool water is reintroduced to 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 to be replaced often.

The essential difference between open and closed looped systems is the open loop’s need for a plentiful 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.

Most often, used water is taken care off in either of these ways: through surface drainage or water re-injection. In returning the water back to the earth, it is crucial to note that there’s no pollution. The only difference in water that’s processed through a geothermal heat pump is a negligible change in temperature.

Before you install 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 exhaust a neighbor’s well source. Be sure to check with your local contractor on whether there’s enough water in the vicinity to warrant installing an open loop geothermal heating system.
