Understanding The Geothermal Heat Pump?
Conventional heat pumps heat homes and buildings by extracting heat from the outside air. In summer months, heat pumps function as air conditioners by reversing the process. Unfortunately, heat pumps are trying to provide heat when the air is coldest outside and to cool when the air is hottest. Thus, in very cold and very hot weather, conventional heat pumps do not operate efficiently.The Geothermal Heat PumpGeothermal heat pumps offer another solution to heat and cool homes and commercial buildings. Instead of exchanging heat with air, these heat pumps exchange heat with the ground or a source of water. This gives geothermal heat pumps a significant efficiency advantage over conventional heat pumps because the ground and water sources are more thermally inert than air. What this means is that the ground below the frost line and bodies of water do not change temperature much no matter what the season. So geothermal heat pumps do not have to work as hard to heat in the winter and cool in the summer as conventional heat pumps do. Consequently, they use significantly less electricity than conventional heat pumps and have less need for auxiliary heating sources. There are two types of geothermal heat pumps. The closed system uses a mix of water and antifreeze that flows through pipes buried in the ground or submerged in a large body of water such as a pond or lake. The open loop system pumps water from a well, pond, or lake through the heat pump and then pumps the water back to the source or to a drainage ditch.Factors to ConsiderGeothermal heat pumps are more efficient than conventional heat pumps, but that efficiency advantage varies greatly. A consumer may see as little as a 20% gain over his current energy source, or he may see in excess of 60% gains in efficiency. Factors such as the local geology, availability of a water source, the type of geothermal heat pump installed, and the cost of the type of energy currently used impact the efficiency gains. Geothermal heat pumps also cost twice as much or more than conventional heat pumps to purchase and install. However, they cost less to maintain and usually have a longer lifespan than conventional heat pumps. Home and business owners should do significant research and seek expert assistance before determining which type of heat pump is right for them.

How did the three sources of heat prevent life from existing when the earth was formed?
the first sources of heat was asteroids and meteorites. another sources of heat for the early earth was the contraction of gravity. the third sources of energy for the early earth was radioactivity. hope this helped :)
Three sources of heat in a home?
People, computers and light bulbs.
What are the three natural sources of heat and light?
sun,stars and fireflies.
What are the four common sources of heat are the sun?
sun fuel electricity and friction
What does air to air mean in heat pumps?
Air to air simply means a heat pump that sits outside of your home and pulls heat from the outside air. This is the most common type of heat pump.
