1. Geothermal Heat Pumps

2. How It Works Different from Geothermal Energy Uses the earth surface not center Finds an area at the earth’s surface that has a source of heat. Usually the Sun

3. Indoor (Evaporator Coil) and outdoor units (Condenser) Refrigerant carries heat from one area of pump to another Heat extracted from ground, brought into house and spread out through vent system Works like a refrigerator

4. Earth Heating Uses the earth as a heat source in the winter Heat Sink in the summer Temperature below 6 meters can match average house room temperature Heat comes from air trapped in earth Even in winter air still holds heat Until -200 degrees Celsius

5. Used For Central Heating in homes and appliances

6. Mad Amounts of Heat Energy source is solar Heat supply runs all year round Even in winter still produces heat Renewable Requires very little electricity to power Environmentally friendly chemicals

7. Depressing Heat Facts High initial installment cost Very large: 3 or 4 times If it breaks, requires specialists

8. Environmental Impacts Produces almost no greenhouse gasses Extremely efficient Basically perfect! All pollution comes from electricity providers That’s not even the heat pumps fault I mean, seriously

9. The emissions Natural Gas furnaces can rival the heat pumps All depends on the area the heat pump is in Good or bad electricity providers

10. Where it is found Mostly in big corporations Commercial Franchises Places with a lot of land, and a lot of money Canada and Russia Not a large market in developing countries

11. Replacing Air Conditioners Always better than electric heaters Up to 50% more efficient than conventional heating or cooling systems Technology constantly improving Almost totally silent

12. Performance Very low maintenance costs once installed Raises value of property Chicks dig heat pumps

13. Longevity CURRENTLY inside equipment lasts around 25 years Outside ground loops last around 50+ years
