The sun’s energy is useful for generating electricity for
your home. It’s also useful for heating and cooling, but not through the use of
solar panel collectors. Geothermal heating and cooling systems also make use of
the sun’s free energy using different collection methods. Ground loop
components actually absorb heat caused by the sun from within the earth to heat
your home, and deposit heat back into the earth for cooling.
Geothermal heating and cooling systems offer the highest
level of energy savings compared to any home system. With geothermal, you can
save as much as 70 percent on heating and cooling costs. This savings is made
possible through the use of the sun’s energy stored within the earth, rather
than fossil fuels.
Even when temperatures outside fluctuate, geothermal
provides steady heating and cooling. It doesn't matter what the outside
temperature is, because the temperature below ground always remains at a
constant level. Usually, this temperature is between 50 and 55 degrees year
round.
For heating purposes, geothermal heating and cooling systems
offer the best return on your heating dollars. They are able to produce about 5
dollars’ worth of heat for every dollar spent for electricity. Even the most
high efficiency furnace can’t do that. In fact, the best a high efficiency
furnace can do is give you back about 98 cents’ worth of heating for every
dollar spent on heating fuels; not much of a payback, is it?
For cooling, central air conditioners and air source heat
pumps drop in efficiency as outdoor temperatures climb, which is typically when
you want and need cooling the most. A geothermal heating and cooling system is
much more efficient. Typically, they more than double the efficiency you’ll
find with air source heat pumps and central air conditioners.
Geothermal heating and cooling systems don’t have exposed outdoor components. Everything you need is either below ground or housed within your home. Central air conditioners and air source heat pumps have outdoor components, leaving them vulnerable to damage, vandalism, and theft.
Most of us take heating and cooling for granted. We expect our heating systems to keep us warm during the winter, and we depend on air-conditioning to keep us cool during the summer.
