GROUND SOURCE, GEOTHERMAL AND GEOEXCHANGE SOLUTIONS by well driller Jesse Yoakum
The Ultimate in Heating/Cooling Efficiency
PLEASE NOTE: It should be understood that three
terms are often used interchangeably for this type of efficient
system. The terms "ground source", "geothermal"
and "geoexchange" mean the same thing.
HOW
IT WORKS
Owners of ground source systems can enjoy high
quality heating and cooling year after year at substantial savings!
Because ground source systems work on a different principle than ordinary
furnace/air conditioning systems, they require less maintenance. Ordinary
furnaces using natural gas or propane create heat through a chemical
combustion by burning fuel. With a ground source system, the earth's
natural heat is collected in water through a series of pipes, called
a loop, installed below the earth's surface. Fluid circulates through
the loop and carries heat into the home. There, the system uses electrically
driven compressors and heat exchangers in a vapor compression cycle
to concentrate the earth's energy and release it inside the home as
heat.
In the summer, the process is reversed to cool
the home. The heat is pulled from the home, carried out through
the loop, and absorbed by the earth.
Ground source systems can also provide all, or
part, of a home's hot water through the addition of a desuperheater
to the system. When the unit is running frequently, homeowners can
obtain all of their hot water in this manner, virtually for free.
Usually borings are drilled and vertical ground
closed loops are installed. There are several other types of loop
systems, such as open, pond, and horizontal ground.
Although we have the ability to drill using any
of the above loop systems, we choose to utilize vertical ground
closed loop. This type seems to be the most efficient for both geological
and weather conditions specific to our area.
SAVINGS
FOR YOU!
Studies have shown that about 70% of the energy
used in a ground source heating and cooling system is renewable
energy from the ground. What this means to you is a savings of up
to 70% in heating costs and 50% in cooling costs, compared to a
conventional system. These systems are highly reliable, require
little maintenance, and are built to last for decades.
