Overview on Geo-Exchange Technology

 1946 First successful Ground Source Heat Pump

installed in Portland, OR

 Primarily open loop systems until 1979, now almost

all are closed loop

 As of 2004, an estimated 12 GW of thermal capacity

installed world wide

 Each year about 80,000 units are installed in the US

SLIDE 4

How Geo-Exchange Works

During the winter, the fluid collects heat

from the earth and carries it through the system and into the building.

During the summer, the system reverses

itself to cool the building by pulling heat from the building, carrying it through the system and placing it in the ground.

This process creates free hot water in the

summer and delivers substantial hot water savings in the winter.

Why Does WMS Promote Geothermal

 Energy Efficiency  Improves system load factor  Is a dispatchable renewable energy source  Lowers customers energy costs  Economic development

SLIDE 6

Energy Efficiency

The GSHP is one of the most efficient residential heating and cooling systems available today, with heating efficiencies 50 to 70% higher than other heating systems and cooling efficiencies 20 to 40% higher than available air conditioners. That directly translates into savings for you on your utility bills.

Lowers Energy Costs

 The average customer will save $580 dollars per

year

 After approximately 22 years they will “break

even” and begin to save even more money

 WMS will also be saving on power generation
