Geothermal Heat Pumps - and a simple explanation of how they dramatically lower your electric bill
Yuma Arizona and the surrounding areas are ideally suitable for geothermal heat pumps- just beneath the surface a layer of wet sand maintains a constant temperature of 75 degrees year round, therefore the use of heat-pump technology can make a big difference in both cooling and heating costs.
Geothermal heat pumps take advantage of the fact that a majority of the Earth's surface just below the ground (between 10 and 15 feet deep) maintains a constant temperature ranging from 50 to 60°F. However Yuma subsurface temperatures average 76 degrees, meaning much less energy is needed to heat or cool air to room temperature, which lowers your use of electricity significantly.
A geothermal pump system consists of pipes buried horizontally in the ground adjacent to a building and then tied into the structure's ventilation system by simply using the subsurface as a heat exchanger. A liquid passed through the pipes picks up residual underground heat in winter, then delivers it to the building, thus warming it. In summer, the liquid transfers heat from the building to the ground, thus cooling the building.
An exciting new tax credit is now available for home and commercial building owners who install geothermal heating and cooling systems through the Energy Improvement and Extension Act of 2008 (H.R. 1424). H.R. 1424 offers a onetime tax credit of 30% of the total investment for homeowners who install residential ground loop or ground water geothermal heat pumps. A credit of 10% of the total investment is also available (no maximum) for a commercial system installation.
There may be other significant tax advantages and federal grant money may available for a limited time that will lower the cost of installation - Bowling experienced technical staff will work with you and provide an analysis that includes the tax rebates and federal incentives for your residential or commercial installation.
