Geothermal Basics Presentation
- 2. What is GeoThermal Technology? Uses Earth’s Renewable Energy Just Below the Surface to Heat and Cool and Provide Domestic Hot Water “Most energy-efficient, environmentally clean and cost-effective systems available today” U.S. Environmental Protection Agency” (EPA)
- 3. How Does GeoThermal Work? Just Below Earth’s Surface, Temperature Remains Fairly Constant Year-Round Water Circulating Through Pipes Buried in the Ground Absorbs Heat in Winter and Carries “Home” Where Heat Pump Transfers to Interior Space for Warmth In Summer, Process is Reversed and Heat is Extracted from the Air and Transferred Through Heat Pump to the Ground Loop Piping Only a Small Amount of Energy Required to Operate Heat Pump, Ground Loop Pump and Distribution Fan or Pump
- 4. Is GeoThermal New? Technology Around Over 50 Years Significant Recent Improvements in Materials, Systems and Efficiencies of Pumps and Compressors
- 5. What Are Major Benefits? Lower Utility Bills (25% to 70%) Reduced Maintenance Higher Levels of Comfort Year Round Environmental Conservation No Fossil Fuel Burned Less Greenhouse Gas Emissions Eliminates Potential Source of Poisonous Carbon Monoxide
- 6. How Popular is GeoThermal? Over One Million Installations in US Today Rapidly Growing As More Learn About The Technology and Its’ Benefits
- 7. Where is GeoThermal Used? Schools Estimated $25M Savings Across US Commercial Enterprises Factories Retail Stores Office Buildings Homes
- 8. Does GeoThermal Cost More? Depends on How You Measure Cost GeoThermal May Cost More Due To Ground Loop Piping HOWEVER…… GeoThermal Systems Have Lowest Life-Cycle Cost Typical 2,000sq ft home as low as $1 a day Installation Costs Declining as More Builders & Contractors Offer Option As Industry Develops Innovative Ways To Install Systems Faster & More Efficiently Costs Are Declining Rebates Offered State and Federal Tax Credits
- 9. Who Can I Hire To Install My GeoThermal System? Proper Design & Installation of GeoThermal Systems is Key Ensure Installer is IGSHPA (“International Ground Source Heat Pump Association”) Certified Check References Ask How Many Installations Completed
- 10. What is a De-Superheater? A desuper heater is a secondary heat exchanger that transfers heat from the earth in the winter and from your home in the summer, into your domestic hot water tank. The desuper heater is part of the geothermal heat pump's domestic hot water generating system (HWG). Hot water generators only heat domestic water when your geothermal heat pump is heating or cooling your home. The hot water generator's water circulating pump moves the cold water from the bottom of your hot water tank through a water pipe to the desuper heater itself, where the water is heated by the heat that has been transferred from the earth when you are heating your home, and from the inside of your home when you are cooling your home. The heated water is then circulated back into your hot water tank.
- 11. What is a De-Superheater? Heating water with a geothermal heat pump's hot water generator costs about 8 percent less in a heating dominated climate, and up to 95 percent less in a cooling dominated climate, than if you heat your domestic water with electric, oil, or propane fired hot water heater. At the present cost of natural gas the savings is about 15 percent less - not as drastic a savings as the others, but saving on your bills is still saving on your bills! In the summer heating your domestic water is “almost” free. This is because the heat that is being removed from your home is transferred into your hot water tank. Since this heat from inside of your home was going to be rejected (thrown away) into the earth anyway, putting it into your hot water tank instead is free. The only cost for the summer water heating is the small cost of running the circulating pump that moves the water.
