Geothermal Heating and Cooling Systems

geothermal 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
How does it work?
  • It simply moves heat energy from one place to another--(like your refrigerator).
definition of heat
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
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
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
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
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
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
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
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
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 in-floor radiant tubing or other hydronic systems.
what about cooling
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
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
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
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
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
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
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
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
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
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
How much hot water will it make?
  • The unit will generally make around 40-60% 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
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
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
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.
