Geothermal Pump
The Environmental Protection Agency and other
environmental and consumer groups are unanimous in extolling the virtues of
geothermal
heat pumps. In fact, the EPA has stated they are the most
energy efficient, environmentally clean and cost effective space conditioning
systems available. That's the kind of endorsement that makes people start wondering
whether a
geothermal heat pump might make sense for them. If you're
one of those people here's some things about geothermal heat pumps you might want to
consider.

Geothermal heat pumps are expensive initially,
but their life cycle costs are substantially less than conventional heating
systems.
Heat pumps cost on average about $2500 per
ton of capacity so an average 3 ton residential unit tons would cost around $7500.
In comparison, a conventional heating unit plus an air conditioner for the same
size home would cost around $4000. Offsetting the higher initial cost, it's
estimated that with a geothermal heat pump a homeowner would save 30 to 60% on
their energy usage. At an average energy cost per home of $1500 per year, that would
be a saving of $450 to $900 per year, providing a payback of the extra cost in 4
to 8 years.
