Ground Loops in Cape Cod, Massachusetts, Geothermal Applications

You’ve just bought or are thinking about purchasing a a new heating and cooling system. Maybe you’re considering a new Geothermal HVAC. Whatever the case, you undoubtedly want to know a bit more about how geothermal works.

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

Ground loops are pretty much just a series of pipes buried in the earth. Various basic sorts of ground loop systems are used for heating and cooling standard residential and commercial]26] buildings.

The way it works is, antifreeze fluid goes through these plastic pipes to get heat effectively and efficiently to a heat pump in your home.

There are four different kinds 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 best system for your house is determined by the specific structure and the property on which it sits. Household systems typically use vertical or horizontal loops.

Below are additional details on each sort of ground loop.

Closed systems, which include vertical, horizontal, and pond loops, continuously move water through them.

Vertical ground loops are used typically in residences because, unlike horizontal loops, they don’t take up much of space. They’re positioned by drilling small-diameter holes in the ground that extend 100-400 feet deep. Then pipes are driven into the holes and connected below the ground to form the vertical loop. Next, additional pipes are attached that channel fluid to the indoor system to transfer the necessary temperature from the ground.

In contrast to a vertical loop system, a horizontal system needs significantly more space but usually costs less considering it uses 2 straight pipes set 6 inches in the earth within an area of ¼ to ¾ acre.

If you want a pond loop system, you plainly 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 Water is then transferred through more pipes beneath the earth to a pump, where the heat is withdrawn and cool water is reintroduced to the pond. That said, in order for this system to work, the water can not 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 a plentiful 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 dwelling or other structure.

Normally, 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 must be pointed out that pollution is not a by-product. 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 vital to know whether a well or pond holds enough water to power your geothermal heat pump, and that it won’t deplete a neighbor’s well source. Make certain you check with your local contractor on whether there’s enough water at hand to warrant installing an open loop geothermal heating system.
