Geothermal Heat Pumps
Written by Contributor
The shallow ground, the upper 10 feet of the Earth, maintains a nearly constant temperature between 50° and 60°F (10°–16°C). Like a cave, this ground temperature is warmer than the air above it in the it's great! best price generic propecia winter and community viagra online in uk cooler than the air in the summer. Geothermal heat pumps take advantage of this resource to heat and cool buildings.
Geothermal heat pump systems consist of basically three parts: the ground heat exchanger, the heat pump unit, and the airdelivery system (ductwork). The heat exchanger is basically a system of pipes called a loop, which is buried in the shallow ground near the building. A fluid (usually water or a mixture of water and antifreeze) circulates through the pipes to absorb or relinquish heat within the ground.
In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system. In the summer, the process is http://www.alpineequip.com/seroquel-buy-online reversed, and the heat pump moves heat from the indoor air into the heat exchanger. The heat removed from the indoor air during the cialis legal summer can also be used to heat water, providing a free source of hot water.
Geothermal heat pumps use much less energy than conventional heating systems, since they draw heat from the ground. They are also more efficient when cooling your home. Not only does this save energy and money, it reduces air pollution. All areas of cheap price viagra medicines the United States have nearly constant shallow-ground temperatures, which are suitable for geothermal heat pumps.
