What is the advantage of using a geothermal heat pump? Geothermal heat pumps can be used to force the transfer of heat. This makes them comparable to a refrigerator or an air conditioner. These devices are capable of transferring heat from a cool temperature and into a warm area. They can be made to go against the natural direction of flow or to enhance the natural flow from a warm area. In fact, these pumps are traditionally far more effective when it comes to heating than air source electric heat pumps-even in cases when these pumps are extracting heat from freezing temperatures.
Air source electric pumps transfer heat to or from the air outside the room. The difference with this type of pump, and the reason that it is so much more effective, is that it exploits the stability of the earth's resources. Because geothermal pumps exchanges heat with the ground, it always has access to the same temperatures underground. These temperatures tend to be much more stable than the winter or summer air.

Pump pumps over your sweating face the clear
Water, cold, so cold! you cup your hands
And gulp from them the dailiness of life.

Usually, the temperature of the shallow ground is warmer than that of the air above, and in contrast, cooler than the air above during summer time. Geothermal pumps use this force to their advantage and thus are considered stable and more effective heating devices. They can also operate as air conditions or heaters.
The main disadvantage of geothermal pumps is that they take money to set up, more so than buying averagely expensive equipment of air source electric heat pumps, and more expensive equipment in dual-fuel pumps. If you choose a system that doesn't take electricity, and only uses geothermal heat, then you could eventually save money-but you won't recuperate your costs until years later. Nevertheless, system life is well over a century if maintained properly.
Geothermal pumps are often mentioned as more efficient "green" energy, the type that could alleviate energy cost and help stop global warming. Manufacturers of these devices include Addison, ClimateMaster, Econar, McQuay and Rheem Classical/Prestige. Some of the top systems available online include the Addison VWY VGY Water Source Self-Contained (8-30 tons), the McQuay Enfinity Horizontal & Vertical Water Source Heat Pumps and the Rheem Prestige Series RPRL-JEZ Two-Stage Heat Pump.

The technology of geothermal pumps dates back to the 1800s, but it continues down into the present day thanks to the stability of our planet's resources. Chris Brown has been researching the top efficient heat pumps for heating his home in the winter and cooling it in the summer. Heat-Pump-Review.net provides an overview of the top heat pumps from the top manufactures.
