The Smart Choice for Energy Efficiency
Th
he Smart Choice for Energ
GEOTHERMAL SYSTEMS
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
confi gurations depending on space availability and soil
properties. Chances are at some point you have either
stood over, or walked across a geothermal loop fi eld.
Loop fi elds 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
fi ttings 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
fi elds, parks or under parking lots.
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.
WELL SYSTEMS
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 effi cient as the well water is always at the same
temperature year-round.
