Why Use Geothermal Energy To Heat and Cool Your Home?
Geothermal Applications

These "Boilerless/Towerless" Heat Pump systems use the natural thermal properties of the Earth to dissipate or capture heat for the water loop. Geothermal Heat Pumps operate in an identical fashion to Water-Source Heat Pump units. However, without the need for a boiler or cooling tower, they save substantial energy costs and space. The water loop system is underground and the units are inside the building. Thus, the environmentally friendly geothermal system preserves the architectural design of a building naturally.

Geothermal Earth Loops

Geothermal Earth Loops come in several different configurations depending on space availability and soil properties. Chances are at some point you have either stood over, or walked across a geothermal loop field. Loop fields can be located under parking lots, landscaped areas, or any number of other locations. All earth loops use high-density polyethylene pipe to circulate either water or an antifreeze mixture. All joints and connection fittings are thermally fused to prevent leaks and most piping comes with a 25-year or longer warranty.

Vertical Loops

Vertical loops utilize bore holes drilled to an average depth of 250 feet. Once the loop pipe is inserted into the bore, it is grouted using a Bentonite mixture for maximum thermal conductivity.

When space is a limited, vertical loops are the most common type of geothermal loop installed.

Horizontal Loops

Horizontal loops utilize trenches dug to an average depth of four to six feet.

As one of the more cost effective loops to install, horizontal loops are commonly found in open fields, parks or under parking lots.

Pond/Lake Loops

Lake loops utilize a "slinky" assembly of geothermal loop piping placed at the bottom of a pond,
lake, or other large body of water.

An extremely cost effective loop system, lake loops are an easy alternative if the option is available.

Open Loop (Water Well)

Most commonly known as "Open Loop", well systems pump water out of a nearby body of water or water well,
and then discharge the water into another body of water or water well.

Well systems usually employ a plate heat exchanger inside the building to keep the building water loop
separated from the well water. This prevents any contaminates from affecting unit performance and extends system life.

Well systems are often the most efficient as the well water is always at the same temperature year-round.

Quick Tips

Tip Thirteen

Warm indoor air contacting the evaporator coils will condense causing moisture to collect and drip. In most units, a plastic pipe carries the water outdoors or to a floor drain. Algae and bacteria growth can clog the pipe, many people will use a pan treatment to retard the growth of algae, etc.
