A major source of energy is right
under your feet.
Your
own backyard has the potential to be your source of heating and
cooling comfort. Now you can get safe, reliable, energy efficient
heating and cooling from one piece of equipment. Geothermal energy
represents the leading edge of heating and cooling technology.
It moves heat energy to and from the earth to heat and cool your
indoor environment. And compared to ordinary systems, geothermal
technology can save you 30% to 60% on your monthly energy bills.
Geothermal is the safest, cleanest, most reliable space conditioning
system you can buy.
Geothermal
energy is an unlimited resource. The lot surrounding a suburban
home or other building contains a vast reservoir of low temperature
thermal energy, typically 10 times that required over an entire
heating season. This resource is constantly resupplied by the
sun, the surrounding earth, and heat rejected while cooling during
the summer. The universal definition of geothermal is "...pertaining
to the heat of the earth." By using the earth to provide
up to 50% of a building's total heating and cooling needs, GHP
systems are truly geothermal energy made practical.
Four
basic types of geothermal energy sources:
Closed loop
systems circulate a water-based solution through a "loop"
of small diameter, underground pipes. In cold weather this solution
absorbs heat from the earth and carries it to the geothermal unit.
The geothermal system amplifies the heat and delivers it indoors.
In warm weather the process is reversed, excess heat is carried
from indoors and into the earth. You keep refreshingly cool during
the hottest summer.
| Horizontal
loops are often considered when adequate land surface
is available. Pipes are placed in trenches, in lengths
that range from 100 to 400 feet. |
 |
| Vertical
loops are the ideal choice when available land surface
is limited. Drilling equipment is used to bore small-diameter
holes from 75 to 300 feet deep. |
 |
Pond (lake) loops are very economical to install when
a body of water is available, because excavation costs
are virtually eliminated. Coils of pipe are simply placed
on the bottom of the pond or lake. |
 |
| Open
loop systems utilize ground water as a direct energy
source. In ideal conditions, an open loop application
can be the most economical type of geothermal system.

Boiler/Tower
Systems
For
efficiency upgrades where large geothermal systems are not viable,
existing boiler/tower jobs are frequently retrofitted. Hybrid
systems incorporate both geothermal loop coupled with down-sized
conventional heat rejection or addition equipment (boiler or tower).
Four
times the efficiency.
A geothermal
system uses the Earth's thermal properties in conjunction with
electricity to provide unprecedented efficiency. For every unit
of electricity the system uses, it provides four units of heating
energy, giving a geothermal system a 400% efficiency rating on
average. These numbers can translate into real savings on your
utility bills year- round.
The
WaterFurnace Advantage:
When
you invest in a WaterFurnace geothermal system, you can be assured
that you are receiving the highest quality, best performing heating
and cooling system available. Here are some of the benefits of
geothermal ownership.
Lower operating costs: The WaterFurnace system operates more efficiently
than ordinary heating and air conditioning systems-30% to 60%
in most cases.
Comfortable:
Because the
unit uses the relatively stable temperature of the earth as an
energy source, you are assured of constant, even winter heating
and better humidity control in summer.
Safe
and clean:
No flame,
no flue, no odors, just safe reliable operation year after year.
Flexibility:
The unit provides
heating, central air conditioning and hot water all from the same
compact unit.
Economical
Water Heating:
Water heating
can be a significant energy expense. WaterFurnace units can reduce
the high cost of water heating by as much as 66%.
Attractive:
The completely
self contained indoor unit needs no noisy, unsightly outside condensing
unit
Environment:
The system
emits no carbon dioxide, which is considered a major contributor
to environmental air pollution.
