Geothermal Heating and Cooling Systems
Geothermal Systems
Use the earth or well-water to provide
heating, cooling and hot water for your
home.
Are also known as GeoExchange because
the systems exchange energy with the
earth.
Have been used successfully for decades.
First patented in 1912.
How does it work?
It simply moves heat energy from one
place to another--(like your refrigerator).
Definition of Heat:
 Heat: (1): A condition of being hot: warmth
(2): A marked or notable degree of hotness
(3) Added energy that causes substances to rise
in temperature, fuse, expand, or undergo any
of various related changes, that flows to a
body by contact with or radiation from bodies
at higher temperatures.
(4) The energy associated with the random
motions of the molecules, atoms, or smaller
structural units of which matter is composed.
- Webster’s Dictionary
How is heat energy
transferred?
The earth has the ability to absorb and
store heat energy
Heat transfer takes place by a liquid
medium (water, antifreeze or well-water)
that works as a conductor to carry the
Heat Energy back and forth to your yard
How does the heat move from the
earth to my home?
The heat moves through a liquid medium inside
a loop system or through a well-water.
Temperature differences between materials or
area cause heat to travel from areas of high
heat (Hi temperature) to areas of lower heat
(Lo temperature) Example: Your coffee always
gets colder not warmer when you leave it set on
the table.
What’s a “loop system”?
Geothermal earth loops are a series of
high density, polyethylene pipe buried in
the ground and connected to your
geothermal unit.
Are there different kinds of
loops?
Closed loop systems-- circulate the same
fluid (water or water & antifreeze)
through the tubing.
Open loop systems-- use well water
Are there different kinds of
closed loop systems?
Closed loops can be:
Horizontal-- placed in trenches
Vertical-- inserted into bore holes
Pond-- placed at the bottom of a pond or
lake
How can it heat using
earth temperatures?
A few feet below the surface, earth
temperatures remain relatively constant
and moderate.
During the heating season, heat is
extracted by the loop system and moved
into the home.
The earth serves as a “heat source”.
How does it heat using
cool earth temperatures?
Although the temperature of the earth may feel
cool to you and me, there is enough heat to
cause the refrigerant inside the unit to change
from a liquid into a gas.
The refrigerant gas is then compressed, making
it very hot, and then it’s passed through an air
coil. As air passes over the hot coil, it is
warmed.
How does this heat my
home?
The warm air is circulated throughout the
home through your duct system.
Or, a geothemal system can make hot
water that can be circulated through infloor radiant tubing or other hydronic
systems.
What about cooling?
A geothermal unit can also cool your
home.
During the cooling season, heat is
extracted from the home and transferred
into the cool earth through the loop
system or well-water.
The earth serves as a “heat sink”.

Do I need separate loops
for heating and cooling?
No. The same loop works for both. All
that happens when changing from heating
to cooling, or vice versa, is that the flow
of heat is reversed.
How much space do I need
to install my loop?
Horizontal loops usually require about 1/3
of an acre of available space.
Vertical loops usually require an area
about 15 feet by 15 feet.
Pond loops can be installed at the bottom
of the pond if the pond has a surface area
of at least 1/2 acre and a minimum of 8
feet deep.
If I use well-water, how
much will I need?
Geothermal units using well-water require
about 5-9 gallons of water per minute,
whenever the unit is running.
After the water runs through the unit, it is
discharged into a ditch, field tile, stream,
pond or another well.
The ONLY change to the water is a few
degrees of temperature difference.
How do I know which loop
is best for my house?
Your ClimateMaster dealer has experience
and training in selecting and designing the
most appropriate and most effective loop
for your home based on installation costs,
digging and soil conditions, moisture, and
the amount of space available.
How do I know that the
loop is the right size?
Scientific based computer software
programs are used to calculate the size of
the loop, based on the heating and
cooling requirements of your home, soil
conditions and your climate.
It’s a science… not a guessing game.
What are the major
components in my unit?
The geothermal unit consists of a
compressor, blower, heat exchangers,
refrigerant piping and valves, electrical
controls and a circulating system
The same type of components used in a
conventional air conditioning or
refrigeration system

How long does my unit
warranty last?
The standard warranty on all ClimateMaster
residential units is 1 year on all parts, 1 year
labor allowance and 4 additional years on the
refrigeration circuit parts
The standard warranty on the loop flow center
pump system is 1 yr labor allowance and 4
additional years on all parts
Extended 5 or 10 yr parts and labor warranty
options are also available
What about the reliability of the
pipe in my loop system?
Pipe is specially formulated for
geothermal installations.
Does not rust, rot, or corrode.
All connections are made by heat fusion.
Warranties vary on pipe from 20 - 55
years. Life expectancy is several hundred
years.
What about hot water?
A geothermal unit can make hot water
too!
An optional component called a
“desuperheater or hot water generator”
makes hot water when your unit is
heating or cooling your home.
Free hot water during cooling
How much hot water
will it make?
The unit will generally make around 4060% of the hot water required for your
home, but the actual amount can vary
significantly depending on how long the
unit runs each day to heat and cool.
The rest of the hot water is generated by
your conventional water heater.
What about hot water for
radiant heating?
Some ClimateMaster units have the ability to
generate hot water for use in radiant floor
heating systems or other hydronic applications.
These Water to Water units generate hot water
for heating plus, it has the ability to operate as
a chiller for applications which need both
hydronic heating and forced air cooling modes.
Can a geothermal system be used
in other applications?
They can also be used for in-floor radiant
heating, pools, spas, fan-coil systems, and
snow melt systems.
In addition to residential applications
geothermal systems are successfully
installed in churches, offices, schools,
apartments, manufacturing plants and
other commercial applications.
How much will I save with
my geothermal system?
There are many variables that must be
considered when calculating operating
costs including: size of home, insulation,
climate, fuel rates, etc.
Your ClimateMaster dealer can perform a
Free Energy Analysis to tell you about
your costs and savings.
In existing homes...
Replacing an existing system with a
geothermal system can save you money
in operating costs.
Your return on the added investment for a
geothermal system can usually be
achieved in 3-5 years.
In new homes...
You’ll generally achieve a positive cash
flow from the first day!
Generally, if you add the extra cost of the
geothermal system into the mortgage,
you’ll find your monthly energy savings
will be greater than the added cost of the
mortgage.
You start saving immediately!
Your energy bill...
If you’re a typical homeowner, about 70%
of your total energy bill is for heating,
cooling and hot water. The rest is for
lighting, appliances and other usage.
Therefore, the biggest opportunity to save
large amounts of money on your energy
bill is to increase the efficiency of your
heating, cooling, and hot water system.
How can I finance my
geothermal system?
For new homes, it can be included in the
cost of your mortgage…(remember
positive cash flow from “day one”)
For existing homes, several financing
programs are available, depending on
your specific needs.
