Advantages Of Using Geothermal Heat Pump Systems

The geothermal heat pump system is probably one of the most notable innovations of recent times in the field of heating and cooling. These heat pump systems work in a similar fashion to that of the traditional refrigeration systems with fluids inside a network of pipes that is used to dissipate or absorb heat from the surrounding. However, unlike refrigeration that uses the surrounding air of its outside atmosphere to maintain its temperature requirements, the geothermal heat pump systems work at an underground level.

Temperatures at about 10 feet underground remain constant irrespective of the changes in weather above ground greenhouse air conditioner. This approach, offers a greater efficiency to the system, and can heat and cool faster since the unit is not combating ambient temperatures.

As far as statistics go, these ground source geothermal heat pump systems are capable or performing at efficiency levels that are at least 400x more efficient than the best air conditioners available in the market, and 200x better than most gas furnaces in the market. These devices can work with one kilowatt/hour of energy to produce 12,000 BTU of cooling and heating, compared to 2.2 Kilowatt/hour energy required by most other standard systems to produce the same amount of output.

These systems are widely recommended by the EPA, various environmental groups, and energy-conscious associations. For instance, the Environmental Protection Agency of the United States recommends these geothermal energy systems are the most energy efficient, environmentally friendly, and money-saving space conditioning devices available to date. Geothermal systems are heavily favored for many reasons. Here are some of the top geothermal heat pump advantages

The simple payback period for each rebuild scenario was calculated (based on incremental annual utility bill savings) without considering rising costs of electricity (which increased 3.3% in this region in the past year) or rises in crude oil prices (which rose 64% in the past year). In the recommended scenario (ENERGY STAR), an estimated 713 MW annually would be avoided, roughly equal to one nuclear power plant serving Hartsville, South Carolina . The increased benefits in savings for local power plants, and the environmental benefits (in an already-challenged region) would be reduced greenhouse gases in the form of CO2 equivalent to removing 51,221 cars from the roads . And for every 1 MW avoided, an estimated $1 million is saved, and similar savings are achievable in reduced distribution costs.

As the rebuilding of the Gulf Coast continues, building energy efficient homes through the 2006 ENERGY STAR for New Homes Guidelines (along with the Indoor Air Package guidelines being piloted) ensure that occupants of these new homes will spend less on medical-related problems and mold-remediation costs long associated with poor construction techniques in hot, humid climates. When considering that indoor air pollution is responsible for one death every 20 seconds , and that the economic impacts of indoor pollution have been estimated at billions of dollars a year , spending a little more on each home to avoid these costs is money well-spent.
Homeowners in Louisiana can access the Louisiana Home Energy Rebate Option (HERO) program, the Home Energy Loan Program (HELP), the Property Tax Exemption, or the Qualified Allocation Plan (QAP) program for rebuilding assistance or tax incentives. In general, the HERO program only requires that homes be built 30% better than the 1995 MEC, an outdated standard; and its cash assistance amounts to an energy efficiency premium up to $2,000. The HELP program, a program of the Louisiana Department of Natural Resources, precludes a homeowner from participating in the HERO program and largely consists of home improvement loans to make energy-related improvements to existing homes.
