How does geothermal energy keep me
warm in winter and cool in summer with
savings of 30 to 60% over my current
energy costs?
No matter where you live, the underground temperature stays
relatively constant all year, even though outdoor temperatures vary
widely. Geothermal systems harness that free, renewable, natural
supply of energy stored below the ground...and use it for heating, air
conditioning and hot water. One system keeps you comfortable both in
winter and summer.
The basic principle of a geothermal system is to transfer the heat
produced by the sun and stored within the earth into the structure
during winter, and to remove heat from indoors in summer and return
it to the cooler earth. Water is used to carry this heat either by
circulating through an underground closed loop piping system or by
directly pumping ground water.
During the heating season...
Water circulating through a “loop” of underground pipe absorbs
heat from the earth and carries it to the Spectra unit which extracts the
heat, compresses it to a higher temperature and distributes it through-
out the building via a duct system.
