The
earth is a massive solar collector that absorbs and stores heat from the
sun. By recovering this free heat a geothermal heat pump achieves an efficiency
level far beyond other heating and cooling systems. If you are
interested in finding out if a geothermal
heat pump would work in your house, read on.
HOW THE CO-OP CAN HELP:
The
co-op will do a complete analysis of the requirements for installing a
geothermal heat pump in your house. It will include the following:
*
Heat loss survey -From a set of plans or by taking measurements
of an existing house, the BTU heating requirements will be calculated.
The heat loss indicates the capacity or size of heat pump needed for
this house.
*
Loop design -Based on heating requirements, a closed loop pipe
system is designed. Usually a vertical closed loop is recommended. It
uses a system of bore holes, similar to wells. The number and depth of
holes is based on the heat loss of the house. These will vary but a
typical installation may have five, 160 ft. holes spaced 12 feet apart.
*
Duct layout -Depending on the situation, the co-op will work with
your contractor to design a duct system that will provide optimum
efficiency and comfort. The duct system is a very important part of a
heating/cooling system.
INSTALLERS:
The
co-op has helped train independent contractors to be ground-source heat
pump installers. They will give you a price for installation that will
usually include labor and materials to backfill the bore holes, labor to
make up the pipe loops, delivering the equipment to the site, duct
materials and labor to install it, wiring, plumbing and purging the heat
pump.
DRILLERS:
Area
well drilling companies are part of the team that makes geothermal heat
pump systems affordable. Arrangements have been made with them to drill
the bore holes, for vertical closed loop systems, at a special price.
HEAT PUMP EQUIPMENT:
The
co-op is a dealer for Command-Aire heat pumps. Co-op members may purchase
heat pumps and pipe from the co-op.
FINANCING:
Existing
homes switching to geothermal heat pumps may qualify for $3000 financing
at 5% for a maximum term of 5 years. This is not available for new
construction.
TO PROCEED:
If
you decide to install a geothermal heat pump, notify the co-op and your
contractor. From that point on, your contractor will coordinate the entire
installation.
WHO YOU PAY:
Somerset
REC for pipe and equipment. Drilling company for bore holes. Contractor
for installing the system.
