The Natural Way. 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 the year round
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 GT-G 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. 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.
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 GT-G Series unit is a lasting investment. Electric utilities, recognizing the dual benefits of high efficiency and low electric peak demand, may provide incentives to purchase these systems.
WARRANTY INFORMATION: GT-G System Series residential warranty reflects the reliability built into every unit and includes one year on all parts with service labor allowance and five years on the compressor and refrigerant circuit parts.
