Geothermal Advantages

Geothermal systems transfer heat from a building to the earth in the cooling mode, or from the earth to the building in the heating mode. Water is used as the heat transfer medium, either in a closed loop piping system, or by directly pumping well water. By using this stable thermal source, geothermal heat pumps provide energy efficient comfort year around.

Highest Efficiency

The extremely high levels of efficiency are possible because a geothermal heat pump only uses electricity to move heat, not produce it. A geothermal unit typically supplies 4 kilowatts of heat for every kilowatt of electricity used. Three of these kilowatts of heat come directly from the earth itself, and are clean, free, and renewable. Overall, geothermal technology offers the highest cooling EER’s and heating COP’s available in the industry. Most systems also include a hot water generator, which diverts a portion of the supplied heat to the domestic water heater. This provides a substantial portion of a family’s hot water needs at a very low cost. Overall, geothermal technology offers the highest cooling EER’s and heating COP’s available in the industry.

Maximum Comfort

Geothermal heat pumps also provide higher comfort levels than traditional space conditioning equipment. By using a relatively warm source of heat such as the earth, supply air temperatures are significantly higher in the heating mode than traditional air-source heat pumps. Geothermal heat pumps also cycle much less often than fossil furnaces, creating a consistent indoor temperature with comfortable relative humidity.

Environmentally Friendly

The environmental advantages of geothermal systems have caught the eye of governmental agencies such as the Environmental Protection

Agency (EPA) and the Department of Energy (DOE). Because it is lowest in CO2 emissions, geothermal technology provides a solution to global warming by primarily using the natural energy

of the earth. In contrast, traditional space conditioning systems depend upon the exploitation and burning of fossil energy sources with the resultant greenhouse gas emissions. Also, Puron® HFC 410A refrigerant is used in the GT-PX series equipment for minimum global warming impact and zero ozone depletion.

Better Investment

Low life-cycle costs are provided by the low operating and maintenance costs of geothermal systems, even when the higher initial installation costs are considered. In new construction, monthly energy savings typically exceed the increased mortgage payments. Therefore, cash flow can be positive from the start. In retrofit systems, a buyer who purchases with cash usually realizes a return on investment well above certificate of deposit rates. And, with equipment life exceeding 20 years, a Carrier geothermal system is a lasting investment.

Electric utilities, recognizing the dual benefits of high efficiency and low electric peak demand, often provide incentives to purchase these systems.

Before choosing a geothermal system, many application factors must be evaluated including:

•Ground water availability and quality

•Loop installation costs

•Land area available

•Sub-soil conditions

•Local codes

•Owner preferences

Carrier dealers have the expertise and computer software to determine the best type of system. Many regions have contractors specializing in the installation of the ground loop portion of the system.
