Geothermal Heating A to Z

• Jeff Johnson

2
Questions That Will Be Answered

• Where does the heat come from?
• How do we produce a higher heat and lower cool?
• What can we do with that heat and cool?
• What are the environmental financial advantages
  of geo?

3
Heat With the Suns Energy

• The earth absorbs 47 of the suns energy.

4
Where Does the Heating and Cooling Come From

• Extracting heat and cool from ground water.
• Extracting heat and cool from a ground loop.

5
1.Extracting Heat From Ground Water.

• Re-injection well system.
• Ground water discharge, A.K.A.Pump
  dump.

Horizontal Slinky Loop
13
Vertical Bored or Drilled Loops

• Standard bore is 140 deep.

14
Pond Loops
15
Icy Pond Loop
16
Crazy Minnesotans
17
Heat From the Loop Goes to a Heat Exchanger
18
Refrigerant Gas to Compressor

• Hot gas gets compressed creating a approximately
  a 51 ratio.
• 30 degree gas compresses to about 150 degree gas.

19
To Summarize
20
Now What Can We Do With The Hot Gas We Have
Created?
21
Hot Gas Is Used to Create Hot Air or Hot Water

• Hot air
• Hot water

22
Forced Air Applications

• Requires duct work to transfer heating and
  cooling to rooms.

23
Forced Air Distribution
24
Hydronic Heat Applications

• Creates hot or cold water solution to use for in
  floor heat and fan coil applications

25
Hydronic Distribution
26
Swimming Pool Application
27
The Environmental Financial Advantages of
Geothermal
28
The EPA Claims That

• Geothermal heat pumps are the most efficient and
  comfortable heating and cooling technologies
  currently available for homes and other
  buildings.

29
Geothermal Systems Strengthen U.S. Energy Security

• Every 100,000 homes with geothermal heat pumps
  reduce foreign oil consumption by 2.15 million
  barrels annually.

30
Electrical Consumption Reduction

• And could reduce electrical consumption by 799
  million kilowatt hours.

31
The Monumental Impact of the Current Geothermal
Heat Pumps

• Taking close to 1,295,000 cars off the road

32
All of These Show a Reduction of Energy
Consumption.

• A reduction in energy helps to provide a greener
  planet
