  • *Mr. Loosleys System:Belt drive compressorAir coil in old oil furnaceDesuperheater added to hot water tankCourtesy Mr. Ed Lohrenz, CGD, GeoXergyClimateMaster

    ClimateMaster

  • *Heat Pump Systems are ReliableCompressor was initially powered by hand crank diesel motor changed to electric motor (still being used!!) in 1953 when his wife couldnt start it.Courtesy Mr. Ed Lohrenz, CGD, GeoXergyClimateMaster

  • *GSHP BasicsClimateMaster

    ClimateMaster

  • ClimateMaster*Geothermal Heat Pump Systems combine Sun, Earth and Waterusing proven technology to create the most energy-efficient, environmentally clean, and cost-effective space-conditioning system

    (according to U.S. EPA 1993)

  • ClimateMaster*Simple Concept Water moves energy better than air doesWater in the ground provides renewable energy

    *Typical water-refrigerant Heat Exchanger used in most GSHP equipment

    ClimateMaster

  • *47% of the solar energy falling on our planet is absorbed by the Earths surfaceClimateMaster

  • ClimateMaster*Geothermal Heat PumpsSelf-containedheating, cooling and hot water

    ClimateMaster

  • ClimateMaster*Geothermal Heat Pumpsare one of the Most Effectiveand Deployable Technologies producing the lowest carbon dioxide emissions, including all source effects, of all available space-conditioning technologies (EPA, 1993)

    ClimateMaster

    ClimateMaster

  • ClimateMaster*Ground Source Heat Pumps offer the greatest potential for energy efficiency of any existing technology

    (EPRI Dec 2009)

    ClimateMaster

  • ClimateMaster*Buildings Dominate U.S. Energy Use and Carbon Emissionswith Heating, Cooling, and Water Heating being the Largest Contributors

    Thermal Loads

    Heating 9.2%

    Cooling 4.3%

    Hot Water 3.8%

    Total 17.3% ~ 20% of all U.S. Carbon Emissions
