Ground Loops in Utah, Utah, Geothermal Applications

You need 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 more about how such a system 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 series of pipes buried in the earth. There are a few basic types of these systems that can be used for heating and cooling common residential and commercial]26] buildings.

The way it works is, antifreeze fluid travels through plastic pipes to move heat fast and efficiently down to a heat pump in the house.

There exist four different sorts of geothermal ground loops: Open Loop, Pond Loop, Horizontal Loop and Vertical Loop. These fall into one of two different categories: either they’re open loop systems or closed loop systems. The right system for your home is determined by the specific structure and the property on which it sits. Residential systems primarily use vertical or horizontal loops.

Below are more specifics on each sort of ground loop.

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

Vertical ground loops are used commonly 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 under ground to form the vertical loop. Next, additional pipes are attached that channel fluid to the indoor system to transfer the needed temperature from the ground.

A horizontal system has to have significantly more space but is usually less costly because it uses 2 straight pipes set 6 inches underground in an area of ¼ to ¾ acre.

If you’re partial to a pond loop system, you plainly must be near a pond, lake, pond, or well. Coils are installed vertically and affixed to the bottom of the water source. Water is then conveyed through more pipes underground to a pump, where the heat is withdrawn and cool water is returned to the pond.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 corrode and filters will need replacing often.

The big 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 for use in heating and cooling your home or other structure.

There are two ways to take care of used water: through surface drainage or water re-injection. In returning the water back to the earth, it must be said that there’s no pollution. The only difference in water that’s processed through a geothermal heat pump is a minor 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 drain a neighbor’s well source. See that you check with your local contractor on whether there’s enough water at hand to support installing an open loop geothermal heating system.
