Overview: Geothermal Heat Pumps

If you're planning to build a new house, office building, or school, or replace your heating and cooling system, you may want to consider a geothermal heat pump (GHP) system. GHP systems are also known as GeoExchange, ground-source, or water- pumps (as opposed to air-source heat pumps). Regardless of what you call them, energy-efficient are available today for both residential and commercial building applications.

A GHP system can be installed in virtually any area of the country and will save energy and money. According to the Environmental Agency (EPA), GeoExchange systems are the most energy efficient, environmentally clean, and cost-effective space conditioning systems available.

While residential GHP systems are usually more expensive initially to install than other heating and cooling systems, their greater efficiency means the investment can be recouped in two to ten years. After that, energy and maintenance costs are much less than conventional heating and air-conditioning systems.

When GHP systems are installed in commercial buildings, the state-of-the-art designs are extremely competitive on up-front costs when compared with cooling towers and boilers, and they have lower energy and maintenance costs.

In addition to their cost effectiveness, GHP systems offer aesthetic advantages, quiet operation, free or reduced-cost hot water, improved comfort, and a host of other benefits.
