Different Geothermal Systems

Ground Water Energy System
Ground Water Energy Systems (Open Loop) have been utilizing the earth's natural
heat source/heat sink ability for over 40 years. Ground Water Energy Systems draw
water from an aquifer via a supply well, pass through the Geothermal heat pump's
heat exchanger where heat is either absorbed or rejected, then returned to the aquifer
via a return well. Ground water temperatures remain very constant (usually within
a degree) though out the year despite wide variations in outside air temperature,
therefore your FHP Unit will maintain it's super high efficiency no matter how hot
or cold it is outside. Ground Water Energy Systems are ideally suited for homes
that have existing water wells available

VERTICAL ENERGY SYSTEMS
Vertical Energy Systems (Closed Loop) utilize the natural thermal properties of
the earth in a similar manor to the Ground Water Energy Systems. However instead
of pumping water out of a well then back into the ground, you simply circulate water
or an antifreeze solution through a closed loop network of plastic pipe that is
inserted into vertical wells. These vertical wells are drilled to a depth of 100
to 300 feet per ton of air conditioning. The Vertical Energy System is ideally suited
for applications when available land area is limited. Similar to the Ground Water
Energy System, the FHP Manufacturing Vertical Energy System avoids wide temperature
swings of the outside air to deliver constant high efficiency and comfort no matter
where you live.

HORIZONTAL ENERGY SYSTEMS
Horizontal Energy Systems (Closed Loop) also utilize the Earth's plentiful and renewable
thermal characteristics. Like the Vertical Energy systems, Horizontal Energy Systems
circulate water or an antifreeze solution through a closed loop network of sealed
and pressurized plastic pipe that is buried in the ground. Instead of inserting
the plastic pipe into vertical wells the pipe is laid into horizontal trenches that
are trenched at a typical depth of 4 to 6 feet and to a length of 75 to 400 feet
per ton of air conditioning. Recent innovations in horizontal pipe configurations
has made this system particularly attractive in first cost as well as operating
efficiency. Typically a little more land area is required to install a Horizontal
Energy System. The same energy saving characteristics are enjoyed with the FHP Manufacturing
Horizontal Energy System as with the Ground and Vertical Energy Systems.

POND / LAKE ENERGY SYSTEMS
Pond or Lake Energy Systems (Closed Loop) may be the most economical system to install
and has many advantages for producing energy savings. This system utilizes a near
by body of water such as a lake or a pond. As with the Vertical and Horizontal Energy
Systems it is a closed loop of sealed and pressurized plastic pipe and water or
an antifreeze fluid solution. Instead of inserting the pipe into a vertical well
or laying the pipe in a horizontal trench the pipe is submerged into a body of water
(pond or lake) where it can utilize the consistent temperature and outstanding heat
transfer characteristics of the water. No wells and very little trenching are required
cutting installation costs. Once again the FHP Manufacturing Pond or Lake Energy
System is not subject to the cruel outside air temperatures that all air-to-air
heat pumps are subject to year after year.
