    1. 1. How Can Free Energy Help Your Business Today?
    2. 2. Geothermal Heat Pumps A Proven Renewable Energy Technology
    3. 3. While Earth travels through Space…
    4. 4. … it Absorbs Energy from the Sun
    5. 5. This natural Energy Collection and Storage System captures nearly 50% of the Solar Energy falling on our Planet… … thus maintaining a nearly constant temperature just below the surface year-round
    6. 6. US Deep Ground Temperatures
    7. 7. … to create “the most energy-efficient, environmentally clean, and cost-effective space-conditioning system” (according to U.S. EPA 1993) Geothermal Heat Pump Systems capture the Solar Energy stored in the Earth using proven technology…
    8. 8. Geothermal Heat Pump Basic Principles
    9. 9. The Earth is the Source of Heat in Winter… Outdoor air design temperature: 0°F in winter 72°F 55°F Insulating layer of earth A geothermal heat pump takes heat from the earth during winter and transfers it into the building
    10. 10. … and an Efficient Place to Reject Heat in Summer… Outdoor air design temperature: 100°F in summer 74°F 55°F Insulating layer of earth A geothermal heat pump cools the building in summer by rejecting heat into the earth
    11. 11. … using Heat Pump Technology A geothermal heat pump is connected to a sealed water piping loop buried in the earth near the building When water exiting the heat pump is pumped through the ground loop, it is naturally warmed (or cooled) by the earth surrounding it Insulating layer of earth
    12. 12. Geothermal Heat Pump Efficiency 1 unit of energy from the grid Plus: 3-5 units of energy from the earth Yields: 4-6 units of energy for the building 400-600% Efficient
    13. 13. Geothermal Heat Pumps Exchange Heat between Air and Water $1 Worth of Electricity to Operate the Compressor and Fan Moves $4 Worth of Heat from the Water Delivering $5 Worth of Heat into the Air Heating Mode Shown Heat can be “pumped uphill” meaning delivered at a higher temperature than the source $4 $1 $5
    14. 14. Geothermal Heat Pumps Heat or Cool on Demand and also Produce Hot Water Operates on the Same Principle as a Refrigerator Cooling Mode Shown 160F Hot water is produced whenever the unit is operating
    15. 15. Heat Pumps Are All Around Us… Air conditioners and air-source heat pumps transfer heat from inside houses to the air outside Refrigerators transfer heat from food into the kitchen B B B HEAT HEAT
    16. 16. Geothermal Heat Pumps Self-contained heating, cooling and hot water
    17. 17. Residential Site Energy Conventional System Over 70% of the energy consumed by a typical home is used for heating, cooling, and water heating
    18. 18. Residential Site Energy Geothermal Heat Pump System Total site energy consumption is cut in half
    19. 19. Geothermal Heat Pumps are the Most Efficient way to convert Green Energy into Heating, Cooling and Water Heating Making the most effective use of this precious resource
    20. 20. Geothermal Systems can be Classified as: Solar Geothermal Renewable Alternative Demand-Side Conservation Energy-Efficiency Zero-Ozone Depleting Environmentally Responsible
    21. 21. Geothermal Heat Pump Installation Methods
    22. 22. Vertical Closed-Loop A pair of pipes with a special U-bend assembly at the bottom is placed into bore holes from 100 to 400 feet deep
    23. 23. Horizontal Closed-Loop A piping array is installed in trenches cut 3 to 5 feet deep and hundreds of feet in length
    24. 24. Surface Water Closed-Loop A piping array is submerged in a pond or lake at least 8 feet deep
    25. 25. Ground Water Open-Loop Well water from an underground aquifer is pumped through the geothermal heat pump and then returned to the aquifer or discharged to the surface
    26. 26. Vertical Closed-Loop Installation Drilling Pipe Loop Insertion Heat Fusing Inside Connection
    27. 27. Geothermal Heat Pumps Are a Scalable Technology
    28. 28. Geothermal Heat Pumps 1300 Square Foot Habitat for Humanity Home Are widely used in Homes and Commercial Properties
    29. 29. Geothermal Heat Pumps Currently Used in Commercial Buildings
