From daily heating to showers and dishes.
Geothermal explained.
Simply put, a geothermal system doesn’t
heat or cool your home by burning fossil
fuels or using electricity in the ways you’re
used to. Instead, it uses electricity to transfer
the near-constant temperatures found deep
in the earth to your home.
Geothermal works on a very simple principle:
no matter what the air temperature is outside,
under the surface of the earth, the temperature
remains constant. Which means that during
the summer, the earth is cooler than the outside
air, and during the winter, the earth is warmer
than the outside air.
A geothermal system works like a heat
pump, only on a much larger scale. In
cold weather, your home is warmed by
heat brought in from the earth. During
warm weather, your home is cooled by
the movement of heat from your home
back into the earth.
There are four types of geothermal ground
loops possible. Your Trane dealer will help
determine which installation works best
for your needs.
Efficiency starts deep inside the earth.
Pond Loop
Uses the water in a nearby lake
or pond to gather or reject heat
through transfer tubes.
Open Loop
Uses existing groundwater
as a heat transfer medium.
Horizontal Loop
When plenty of space is
available, the heat transfer
tubes are not as deep, and
extend out rather than down.
Vertical Loop
When space is limited, the
heat transfer tubes are sunk
straight down into the earth.
Most EnviroWise
™
geothermal systems
have a hot water generator option that
can be used to heat the water you need
throughout the day, for everything from
showers to laundry and dishes. So in
addition to more efficient heating and
cooling for your home, you’ll also save
the energy you’d normally use to power
a water heater. It’s just one more way a

Geothermal System
can help keep you comfortable and
more energy efficient.
