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.  Betinite 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 a
systems operation.

WORK.
Horizontal loops are put in either single pipes , multi pipes, or slinkeys.
The most cost effective and effective loop system,but  takes ground
space to lay the loop. Again, engineering of the system and thermal
conductivity of the soil is imperative to the system operation.
Tax Credit Information for 2006-2008
The federal tax credits for the installation of geothermal equipment and for the
construction of energy efficient homes are available from January 1, 2006 to
December 31, 2008. The homeowner is eligible for a tax credit of up to $300
for the installation of a geothermal system with a desuperheater connection for
hot water assist. In addition, the system must generate efficiency ratings of
14.1 EER and 3.3 COP for a closed loop, 16.2 EER and 3.6 COP for an open
loop, and 15 EER and 3.5 COP for a direct expansion system.
Builders are eligible for a $2,000 tax credit for energy efficient homes
achieving a 50 percent higher energy savings than the 2004 International
Energy Conservation Code (IECC) and supplements, and contractors are
eligible for a $1,000 credit for manufactured homes achieving an over 30%
higher energy savings than the 2004 IECC and, or EPA requirements under the
ENERGY STAR program. In addition, regular energy efficient homes are
required to have 20 percent of the energy savings come from the building
envelope, and 30 percent is required for manufactured homes. In order for
these credits to apply, the home must be built in the U.S. after August 8, 2005,
and used as a residence within the timeframe of January 1, 2006 through
December 31, 2008.
When filing for the federal and state tax incentives, the homeowner should
have proof of purchase, and keep an ARI Certificate on file, which states the
performance ratings of their equipment. Also, two certificates should be
printed off if the homeowner has a dual capacity system.

88hvac is dedicated to the greenest and most mechanically sustainable solutions to your HVAC system. With
energy cost sky rocketing to $135 per barrel, our fuels and electric cost will soon follow. Geothermal operates at
500% efficient. This is 5x worth of heating or cooling energy , when you give it 1 kw of electricity!
Every Geothermal Install we find better and price saving techniques that we pass on to you.
We are working on cost effective drilling techniques that will be much less than vertical drilling and  less
destructive to the land scape as would be a horizontal slinky. Call us for information  and see what type savings
and comfort you can have from a GSHP geothermal HVAC system.

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 energyefficient,
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, equipment
and 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 the
form 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 cooling
season.
GeoExchange Heating and Cooling
Systems: Fascinating Facts
· EPA found that, even on a source fuel basis – accounting for ALL losses in the fuel cycle
including 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 emissions
reductions:
 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 oil
per year.
