Ground Loops in Lime Springs, Iowa, Geothermal Applications

You’ve finally gotten, or are contemplating getting, a 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 more about how one works.

Geothermal HVACs take consistent temperature from the ground to deliver hot or cool air to your home’s interior. 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 ground loop systems are used for heating and cooling conventional residential and commercial]26] buildings.

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

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 right system for your house is determined by your structure and the property on which it sits. Home systems mostly use vertical or horizontal loops.

Below are additional details on each kind of ground loop.

Closed systems, which include 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 take up a lot of space. They’re set in place by drilling small holes in the ground to a depth of 100-400 feet. Then pipes are driven into the holes and connected under ground to form the vertical loop. Next, extra pipes are attached that carry fluid to the indoor system to transfer the needed temperature from the ground.

A horizontal loop system has to have significantly more space but is actually not as expensive considering it uses only 2 straight pipes set 6 inches in the ground within an area of ¼ to ¾ acre.

If what you want is a pond loop system, you plainly must be close to a pond, lake, pond, or well. Coils are installed vertically and
secured to the bottom of the water source. Water is then transported through more pipes beneath the earth 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 not be acidic or else pipes will decay and filters will have to be replaced often.

The essential difference between open and closed looped systems is the open loop’s need for an ample source of groundwater, a well or a pond, for instance. From there, it directly pumps water into the heat pump unit to be used in heating and cooling your home or other structure.

Generally speaking, 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 important 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.

Before you install 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 drain a neighbor’s well source. See that you check with your local contractor on whether there’s enough water available to go ahead with installing an open loop geothermal heating system.
