Geothermal Heating / Geothermal Heat PumpsGeothermal Heating / Geothermal Heat PumpsAllie PaccadolmiHow They WorkSplit System outdoor unit (condenser) and indoor unit (evaporator coil)Compressor changes gaseous refrigerant to high pressure gasRefrigerant cools and changes into a high temp gasLiquid refrigerant expands and turns into gas gas then absorbs heat from circulating airAdvantagesTwice as efficient as the top-rated air conditionersEnergy costs are 30-70% lowerReduces greenhouse gas emissions equivalent to planting 750 treesDisadvantagesInitial cost is high two to three times higher than a conventional heating/cooling systemOpen-loop systems bring in water from outside, can lead to clogging, mineral deposits, or corrosion of pipesImpact on the Environment?Reduces greenhouse gas emissions 5.9 million CO2 emissions cut 1.6 million C emissions cut Compared to other Energy SourcesLasts longer abt 50 years longerNo gas lines no potential for leakage or fireRestrictionsOpen-loop systems: need a large supply of clean water to be most efficientLimits use in coastal, lake, and river areasFactsTakes only 1 kW/hr for a geothermal heat pump to produce nearly 12,000 Btu of cooling or heating. (To produce the same number of Btus, a standard heat pump consumes 2.2 kilowatt-hours.) 50% more efficient than the best gas furnaces70% of energy used in a geothermal heat pump system is renewable energy from the groundWebsiteshttp://climatelab.org/Geothermal_Heat_Pumps http://www.residential.carrier.com/products/geothermalheatpumps/index.shtmlhttp://www.consumerenergycenter.org/home/heating_cooling/geothermal.htmlhttp://www.thisoldhouse.com/toh/article/0,,20162296,00.html
