The US Government
will pay for 30% of your Geothermal heating
and cooling system! Be green; Save some
green; Stop buying foreign fuel (Oil, natural
gas) from countries that do not like us!

Did you know that your
moist soil can actually heat and cool your
home for up to 60% less than you are currently
spending? (without burning oil or gas, or
producing greenhouse gasses) Geothermal
energy works by using the relatively constant
temperature of the earth and using that
as a heat source and heat sink to heat and
cool your home. During the winter, heat
is extracted from the earth by piping liquid
through a network of polyethylene tubing
that runs beneath the earth. During the
summer, the process is reversed and the
hot air from your house is pumped into the
relatively cool 55 degree earth. This process
is much more efficient that your traditional
noisy central air conditioner units because
the hot air is moved to the comparatively
cool earth rather than pumping the hot air
into the 98 degree atmosphere. This leads
to efficiencies as high as a 30 SEER for
air conditioning! Geothermal systems also
have the added benefits of extremely quiet
operation when compared to traditional central
air conditioning systems. Geothermal systems
will also produce a more even heating when
compared to fuel fired heating systems because
warm air is continuously circulated.

horizontal ground loop.
It just
so happens that saturated ground has a much
higher specific
heat capacity and thermal
conductivity than does dry ground. For
this reason, geothermal loops that are installed
in saturated ground will perform much more
efficiently than those that are installed
in dry earth. This increased efficiency allows
for a faster payback period on these systems,
and makes geothermal an ideal choice for houses
that also have drainage issues due to saturated
ground. Bobcats for Hire can provide you with
a drainage solution that will not only dry
up your yard and basement, but also incorporate
a Geothermal system that can save you up to
60% on your heating, air conditioning, and
hot water bills in the same project! If you
currently heat with either electric or propane,
your savings will be even higher than that.
To the right and above is a geothermal ground loop designed and installed by Bobcats for Hire. This seven ton system used 3600 feet of polyethylene tubing and consisted of a header pipe that is 1.25" and eight circuits that are 3/4" HDPE tubing. We use 200 PSI Endot sdr 11 geothermal pipe that is the strongest in the industry and is frequently used for water lines and gas lines. Any connections that are buried are heat fused together to ensure that they can never leak. This process fuses the tubing together and makes the connection even stronger than the pipe itself. Water mixed with an environmentally safe antifreeze solution is pumped through the loop field where it will extract stored heat from the earth during heating system and deposit heat removed from the home during the cooling season. Geothermal heat pumps help to reduce peak loads on the Nation's electric grid by significantly lowering electrical usage for hot summer air conditioning needs. The New Jersey Clean Energy Program is currently offering rebates on Geothermal systems of $500 per ton! This link to Geoexchange.us can answer many common questions on the basics of geothermal heating and cooling. The US Department of Energy provides additional information on the many benefits of geothermal energy. We are an authorized dealer for Geocomfort made by Water Furnace, and can offer many different configurations to optimize your installation and system.
Designing a geothermal
system requires a thorough knowledge of many
engineering aspects of both soil mechanics
and hydrology. Among them are characteristics
of the soil such as specific heat and moisture
content, heat loss rates of the structure,
pipe hydraulics, water velocity through the
loop field, pump curve characteristics, and
proper equipment sizing. Bigger is definitely
not better with geothermal heating and cooling.
An accurately sized loop field and geo unit
will have a lower first cost, cost less to
operate, last longer, and provide better comfort
than a system that is either over or undersized.
As a geothermal designer, one needs to be
acutely aware of the many intricacies that
affect the performance of the geothermal system.
Steve wrote his master's thesis on the elements
of geothermal design including the design
of a 200 ton geothermal heating and cooling
system for a school. Steve Therianos will
consider many of the above site specific criteria
when designing your geothermal system to ensure
that your system will provide decades of comfort,
energy savings, and environmental benefits.
