Vertical bore holes are required to place 3408 hdpe 3/4" to 1.25" vertical pipe into the ground.
This pipe delivers the energy transfer between the earth and equipment.  Grout is needed to keep
the conductivity of the soil and the ground loop in constant connection. Thermal conductivity
and engineering of the system is imperative for systems operation.
SEE SOME OF
OUR HVAC WORK.
Horizontal loops are put in either a 6 pipe configuration  or slinkeys.
The most cost effective and effective loop system installation but  takes alot of ground space to
lay the loop. Again, engineering of the system and thermal conductivity of the soil is imperative
to the system operation. Planed right, ground loops can pay you to be installed.
Geothermal Tax Credits for 2009

An exciting new tax credit is now
available for home and commercial
building owners who install
geothermal heating and cooling
systems through the Energy
Improvement and Extension Act of
2008 (H.R. 1424). H.R. 1424 offers a
one time tax credit of 30% of the total
investment (maximum of $2,000 for a
single residence) for all residential
ground loop or ground water
geothermal heat pump installations. A
credit of 10% of the total investment is
also available (no maximum) for a
commercial system installation.
To qualify, the systems must meet or
exceed EnergyStar requirements and
be installed after December 31, 2007.
Owners can file for the credit by
completing the Renewable Energy
Credits subsection on their tax return
forms for 2008. For taxpayers that are
subject to the Alternative Minimum
Tax, they can claim the credit on their
taxes for the following year. No proof
of purchase will be required;
however, in case of an audit, owners
are encouraged to keep a detailed
invoice of their purchase on file. The
contractor who sold and installed the
product should list the purchase as a
"Geothermal Heat Pump" on the
invoice and that it "Exceeds
requirements of Energy Star program
currently in effect".
The tax credit is available from
October 3, 2008 through December 31,
2016. For more information, visit
http://thomas.loc.gov or contact your
local tax professional.

88hvac specializes in geothermal HVAC sytem. From Verticle well drillers, to HDD Geothermal Drillers, to 6 pipe installations, slinkey
installations, hybrid loop solutions, and Swiming pool loop installations. Our goal is a high efficient system that has the cost beifits to
go with it. Since 1999 we have been working in ground source geothermal industry, and not untill the energy needs of 2000 has there
been a more need for green systems to curb energy use. Geothermal equipment today is much more efficient than last year. Lets say
in some cases there are systems that can operate at $1 worth of power and give you back $20 in heating or cooling. COP 20?

The U.S. Environmental Protection Agency has identified geothermal heat pumps as a
technology that significantly reduces greenhouse gas and other air emissions associated
with heating, cooling and water heating residential buildings, while saving consumers
money, compared to conventional technologies.1 For every 100,000 units of typically
sized residential geothermal heat pumps installed, more than 37.5 trillion Btu’s of energy
used for space conditioning and water heating can be saved, corresponding to an
emissions reduction of about 2.18 million metric tons of carbon equivalents, and cost
savings to consumers of about $750 million over the 20-year-life of the equipment.
· Geothermal heat pump systems, also known as “geoexchange,” are the most energy
efficient, environmentally clean, and cost-effective space conditioning systems available,
according to the Environmental Protection Agency.1
· Geothermal heat pumps strengthen U.S. energy security. Every 100,000 homes with
geothermal heat pump systems reduce foreign oil consumption by 2.15 million barrels
annually and reduce electricity consumption by 799 million kilowatt hours annually. ·
Geothermal heat pumps are efficient. The use of geoexchange lowers electricity demand by
approximately 1 kW per ton of capacity. · Geothermal heat pumps are environmental. They
generate no on site emissions and have the lowest emissions among all heating and
cooling technologies. 1 · Geothermal heat pumps save money. Schools now using
geothermal heat pump systems save more than $25 million in energy costs – meaning
more money for books, equipmentmand teachers. Homeowners can save 25 to 50 percent
on home electric bills compared to conventional heating and cooling systems. Electric bills
for a 2,000 sq. ft. home can be reduced to as low as $1 a day, using a geoexchange system. ·
Geoexchange systems represent a savings to homeowners of 30 to 70% in the heating
mode and 20 to 50% in the cooling mode, compared to conventional systems. · EPA found
that geoexchange heating and cooling systems can reduce energy consumption—and
corresponding emissions—by more than 40% compared to air source heat pumps and by
over 70% compared to electric resistance heating with standard
air-conditioning equipment. · Geoexchange systems use the Earth’s energy storage
capability to heat and cool buildings,  and to provide hot water. The earth is a huge energy
storage device that absorbs 47% of the sun’s energy – more than 500 times more energy
than mankind needs every year – in theform of clean, renewable energy. Geoexchange
systems take this heat during the heating season at an efficiency approaching or exceeding
400%, and return it during the coolingseason. GeoExchange Heating and Cooling
Systems: Fascinating Facts · EPA found that, even on a source fuel basis – accounting for
ALL losses in the fuel cycleincluding electricity  generation at power plants – geoexchange
systems are much more efficient than competing fuel technologies. They are an average of
48% more efficient than the best gas furnaces on a source fuel basis, and over 75% more
efficient than oil furnaces. In fact, today’s best geoexchange systems outperform the best
gas technology, gas heat pumps, by an average of 36% in heating mode and 43% in
cooling mode! · The U.S. General Accounting Office estimates that if geoexchange systems
were installed nationwide, they could save several billion dollars annually in energy costs
and substantially reduce pollution.2 · Surveys by utilities indicate a higher level of
consumer satisfaction for geoexchange systems than for conventional systems. Polls
consistently show that more than 95% of all geoexchange customers would recommend
geoexchange to a family member or friend. · Today there are now more than 1,000,000
geoexchange installations in the United States. The current use of geothermal heat pump
technology has resulted in the following emissionsreductions:
 Elimination of more than 5.8 million metric tons of CO2 annually
 Elimination of more than 1.6 million metric tons of carbon equivalent annually · These
1,000,000 installations have also resulted in the following energy consumption
reductions:
 Annual savings of nearly 8 billion kWh
 Annual savings of nearly 40 trillion Btus of fossil fuels
 Reduced electricity demand by more than 2.6 million kW
· The monumental impact of the current use of geoexchange is equivalent to:
 Taking close to 1,295,000 cars off the road
 Planting more than 385 million trees
 Reducing U.S. reliance on imported fuels by 21.5 million barrels of crude oilper year.
