High Energy Savings with a Low Initial Investment
Use Earth’s energy to heat and cool your home.
Geothermal heat pump systems are an incredibly quiet and
efficient way to heat and cool your home. Because you are using
the natural energy from the Earth, you can reduce your monthly
utility bills by as much as 70 percent. Best of all, geothermal
systems can be installed in any sized home in almost any location.
Save energy. Save money.
Typical central cooling systems work by exchanging heat with the
air. Because ambient air temperatures can vary greatly, how hard
the system has to work varies as well. When temperatures outside
are very hot, for instance, it is harder to disperse heat into already
hot air.
A geothermal heat pump, on the other hand, exchanges heat with
the ground. While the air outside will vary in temperature, the
ground stays a fairly consistent 55°-70°F year-round. That means
a geothermal system doesn’t have to work nearly as hard to
disperse heat as a traditional split-system air conditioner or heat
pump, which is how it operates so efficiently.
In the winter, geothermal heat pumps simply move the heat from
the ground to your home. Unlike a gas furnace, geothermal heat
pumps don’t burn a fuel source to create heat.

HOW EARTHDIREXTM GEOTHERMAL DIRECT
GEOEXCHANGE HEAT PUMPS WORK
Earth loops. A direct exchange geothermal system uses a series
of underground refrigerant tubes called an “Earth loop.” A typical
installation includes a small trench and/or one to two 5- to 6inch diameter boreholes drilled to depths of 400 feet or less. The
refrigerant tubes are placed into these holes, which is how they
access the natural heating and cooling power of the Earth.
The tubes connect through the house to a compressor and an air
handler that sits inside. When running, the compressor unit makes
about as much noise as a refrigerator and is quieter than an electric
fan. There is no unsightly and noisy outdoor unit. In areas near the
seashore, there is no exterior equipment subjected to corrosive saltwater air.
Take advantage of a 30%
geothermal tax credit.
U.S. homeowners who
install an ENERGY STARrated geothermal system
can take advantage of a
30% tax credit – that’s
30% back on both the
equipment and the
installation costs. The
credit is scheduled to be
in effect until the end of
2016. Talk with your tax
advisor for more details.
Earth loops use the Earth’s
consistent temperature to
cost-effectively heat and
cool your home.

QUALITY
EARTHDIREXTM VS. OTHER GEOTHERMAL SYSTEMS
Several types of geothermal heat pumps exist, but not all are equal in
performance or design. Here’s why you should consider a EarthDirEX
system.
Less expensive. EarthDirEX geothermal direct
geoexchange heat pumps require much less drilling
SAVINGS
than other geothermal systems. Drilling can account
for half of your total cost, so reducing drilling can
significantly reduce your initial investment.
100% refrigerant. With the EarthDirEX system, there
is no refrigerant-to-water heat exchanger component,
so the heat pump transfers heat more efficiently. Other
geothermal systems transfer heat from refrigerant
to water to the Earth and back again. EarthDirEX
transfers heat simply from the refrigerant to the Earth.
Fewer moving parts. An EarthDirEX system has only
two primary moving parts – a compressor and a
blower – which means you have less to service and
less to potentially break down over time.
Outstanding Warranty.
Westinghouse products
offer a 10-year limited
warranty on all parts, and
a 10-year Quality Pledge
at no extra cost (when
product is registered
as part of a complete
Westinghouse system).
With our 10-year Quality
Pledge, we will replace
the indoor unit should
the compressor fail
within the first 10 years.
To learn more about
our product warranties,
ask your Westinghouse
contractor, or visit us

Electronic expansion valve. While other geothermal
heat pumps use a thermal expansion valve, EarthDirEX
uses an electronic one for precise refrigerant control.
Greater corrosion resistance. EarthDirEX geothermal
heat pumps utilize all-aluminum Anteater MC® MicroChannel coils for superior protection against leaks
caused by corrosion.
Westinghouse EarthDirEX geothermal direct
geoexchange heat pumps are energy-efficient,
environmentally responsible products. Look for the
ecoLogic® seal.
