2. The Basic’s Of Geothermal - It’s What’s Underneath that Counts!

3. Space 17% reflected by clouds. 100% 6% reflected by surface. Atmosphere 19% absorbed by water vapor, dust 4% absorbed by clouds. 46% absorbed by ground Earth The earth is like a solar battery absorbing nearly half of the sun’s energy. The ground stays a relatively constant temperature through the seasons, providing a warm source in winter & a cool heat sink in summer.

7. Vapor / Compression Refrigeration Cycle

8. Geothermal Benefits • Free and Renewable Energy • Quiet operation • Safe – all electric • Increased Comfort • Substantial Energy Savings • Reliability & longer life expectancy • Lower maintenance • Less impact on the environment

9. Typical Home Energy Usage

10. Typical Home Energy Usage With a Geothermal System

11. System Materials & Components • Ground loop • Plastic pipe – high density polyethylene which is a higher grade than natural gas pipelines • Standard 50yr warranty on pipe from Manufacturer • Heat fusion method of joining pipe & fittings – very reliable method which makes one continuous pipe • Antifreeze heat transfer solution-Food grade • Small pumping station-low energy consumption and reliable components • 200 year theoretical life expectancy of buried pipe

12. Which Type of Ground Loop? • All loops are sized for the same results. • Each produces about the same annual operating costs. • Choose the most economical loop to install

13. Which Type of Ground Loop? • Closed loop - Vertical, horizontal, and pond • Contains 100-150 gallons of fluid • Open loop – Uses ground water from well • Requires water flow of approximately 1.5 – 2 gallons per minute per nominal ton • Average system uses 500,000 gallons of water/year

14. Surface Water/Pond Loops • Least expensive • Typically requires 1/4 acre pond at least 10-12 feet deep

16. Single plate / 6 Ton unit 4 – 8 Ton plates / 32 Tons

17. Horizontal Loop Configurations

18. Horizontal Loops • Normally can be less expensive • Typically requires 300-400 foot of trench per ton • Or 600-800 feet of pipe per ton

19. Horizontal loop / fusion

20. Vertical loops • Requires less area • Typically 3-6 bores of 150-200 feet deep per bore • One bore per ton of required load • Sealed with grout to prevent contamination of ground water
