How efficient is a GSHP?
The GSHP is one of the most efficient residential heating and cooling systems
available today, with heating efficiencies 50 to 70% higher than other
heating systems and cooling efficiencies 20 to 40% higher than available
air conditioners. That directly translates into savings for you on your
utility bills.
Can one system provide both space heating and cooling for my
home? And what about heating hot water?
Yes. A GSHP can be a combination heating/cooling and hot water heating
system. You can change from one mode to another with a simple flick on
your indoor thermostat. Using a desuperheater, some GSHPs can save you
up to 50% on your water-heating bill by preheating tank water.
How long will my GSHP system last?
GSHPs are durable and highly reliable. The GSHP contains fewer mechanical
components, and all components are either buried in the ground or located
inside the home, which protects them from outside conditions. The underground
pipe carries up to a 50-year warranty.
How noisy is the GSHP unit?
GSHPs are very quiet, providing a pleasant environment inside & outside
of the home. GSHPs have no noisy fan units to disturb outdoor activities,
on or near the patio.
How safe are GSHPs?
GSHP systems are safe and protected. With no exposed equipment outdoors,
children or pets cannot injure themselves or damage exterior units.
GSHPs have no open flame, flammable fuel or potentially dangerous fuel
storage tanks.
How will I save money with a GSHP?
GSHPs save money, both in operating costs and maintenance costs. Investments
can be recouped in as little as three years. There is a positive cash
flow, since the energy savings usually exceeds payment on the system.
Will my existing ductwork function with this system?
Yes, in most cases. Your dealer or installer will be able to determine
ductwork requirements and if any minor modifications are needed.
Will an underground loop affect my lawn or landscape?
No. Research has shown that loops have no adverse effects on grass, trees,
or shrubs. Most horizontal installations require trenches about six
inches wide. Temporary bare areas can be restored with grass seed or
sod. Vertical loops require little space and do not damage lawns significantly.
My yard contains many shade trees. Will this affect ground temperature and my ability to use it as an energy source?
Not at all. The system is installed deep enough that it utilizes constant
ground temperature.
Do soil freezing conditions create any problems?
Not if a system is properly designed and installed. The three to four
foot depths allow the sun to melt the frozen soil during the summer.
Adequate length per ton capacity prevents objectionable soil movement.
