When you build a spectacular home, you take time to
choose the location, style of the building, internal
furnishings and everything to ensure your comfort. Within
these post and beam rooms a forced air system was
chosen to best match it’s heating and cooling needs. Then
to minimize operating costs while maximizing their comfort,
these homeowners installed a safe, clean and energy

efficient Geothermal system.
A Geothermal system has two
main components, the heat-
pump and a heat-reservoir. The
geothermal heat-pump (in this
home a reliable WaterFurnace
unit was selected), uses similar

technology to that of a home refrigerator to exchange
heat energy between the home’s interior and the
heat-reservoir. Bringing heat energy inside during
the winter and taking heat energy out of the home in
the summer. There is no combustion, so no chance
of carbon monoxide emission and only the whisper
quiet air circulation pump when operating.

This home’s geothermal heat-reservoir is a beautifully
landscaped pond that naturally collects and stores the

sun’s heat energy throughout the year. Header pipes
are run below ground from the home to the pond in
which heat exchange loop-coils are submerged. In this
installation the loop-coils are closed, only heat energy
is exchanged with the pond, which ensures a long
lifespan and continued low ownership costs.
This Geothermal system, together with a Heat-Recovery
Ventilator to regularly refresh inside air, maintains the
desired quality, quiet comfort and low operating costs
these energy-smart homeowners desired.

Geothermal systems are
on average 48% more
efficient than the
highest efficiency gas
furnace on a source fuel
basis and over 75%
more efficient than oil
furnaces.

Todays Geothermal
systems out perform the
best gas technology by
an average of 36% in
heating mode and 43%
in cooling mode....more
EPA findings

For every 100,000
typically sized residential
geothermal systems
installed, more than
37.5 trillion BTU's of
space heating and water
heating energy can be
saved. This corresponds
to an emissions
reduction of about
2.18million metric tons
of carbon equivalents,
and a cost saving to
customers of about
$750 million over a 20
year period....more EPA
