Homeowners in virtually every region of the United States are enjoying a high level of comfort and significantly reducing their energy use today with
geothermal heating and cooling.
This marvelous technology relies primarily on the Earth’s natural thermal energy, a renewable resource, to heat or cool a house or multi-family
dwelling. The only additional energy geothermal systems require is the small amount of electricity they employ to concentrate what Mother Nature
provides and then to circulate high-quality heating and cooling throughout the home.
Homeowners who use geothermal systems give them superior ratings because of their ability to deliver comfortably warm air, even on the coldest
winter days, and because of their extraordinarily low operating costs. As an additional benefit, geothermal systems can provide inexpensive hot water,
either to supplement or replace entirely the output of a conventional, domestic water heater.
Geothermal heating and cooling is cost effective because it uses energy so efficiently. This makes it very environmentally friendly, too. For these
reasons, federal agencies like the Environmental Protection Agency and the Department of Energy, as well as state agencies like the California Energy
Commission, endorse it.
Owners of geothermal systems can relax and enjoy high-quality heating and cooling year after year. Geothermal systems work on a different principle
than an ordinary furnace/air conditioning system, and they require little maintenance or attention from homeowners. Furnaces must create heat by
burning a fuel--typically natural gas, propane, or fuel oil. With geothermal systems, there’s no need to create heat, hence no need for chemical
combustion. Instead, the Earth’s natural heat is collected in winter through a series of pipes, called a loop, installed below the surface of the ground
or submersed in a pond or lake. Fluid circulating in the loop carries this heat to the home. An indoor geothermal system then uses electrically-driven
compressors and heat exchangers in a vapor compression cycle--the same principle employed in a refrigerator--to concentrate the Earth’s energy and
release it inside the home at a higher temperature. In typical systems, duct fans distribute the heat to various rooms.
In summer, the process is reversed in order to cool the home. Excess heat is drawn from the home, expelled to the loop, and absorbed by the Earth.
Geothermal systems provide cooling in the same way that a refrigerator keeps its contents cool--by drawing heat from the interior, not by injecting
cold air.
Geothermal systems do the work that ordinarily requires two appliances, a furnace and an air conditioner. They can be located indoors because there’s
no need to exchange heat with the outdoor air. They’re so quiet homeowners don’t even realize they’re on. They are also compact. Typically, they are
installed in a basement or attic, and some are small enough to fit atop a closet shelf. The indoor location also means the equipment is protected from
mechanical breakdowns that could result from exposure to harsh weather.
Geothermal works differently than conventional heat pumps that use the outdoor air as their heat source or heat sink. Geothermal systems don’t have
to work as hard (which means they use less energy) because they draw heat from a source whose temperature is moderate. The temperature of the
ground or groundwater a few feet beneath the Earth’s surface remains relatively constant throughout the year, even though the outdoor air
temperature may fluctuate greatly with the change of seasons. At a depth of approximately six feet, for example, the temperature of soil in most of
the world’s regions remains stable between 45 F and 70 F. This is why well water drawn from below ground tastes so cool even on the hottest
summer days.
In winter, it’s much easier to capture heat from the soil at a moderate 50o F. than from the atmosphere when the air temperature is below zero. This
is also why geothermal systems encounter no difficulty blowing comfortably warm air through a home’s ventilation system, even when the outdoor air
temperature is extremely cold. Conversely, in summer, the relatively cool ground absorbs a home’s waste heat more readily than the warm outdoor air.
Studies show that approximately 70 percent of the energy used in a geothermal heating and cooling system is renewable energy from the ground.
The remainder is clean, electrical energy which is employed to concentrate heat and transport it from one location to another. In winter, the ground
soaks up solar energy and provides a barrier to cold air. In summer, the ground heats up more slowly than the outside air.
Making Hot Water
Geothermal systems can also provide all or part of a household’s hot water. This can be highly economical, especially if the home already has a
geothermal system, hence a ground loop, in place.
One economical way to obtain a portion of domestic hot water is through the addition of a desuperheater to the geothermal unit. A desuperheater is
a small, auxiliary heat exchanger that uses superheated gases from the heat pump’s compressor to heat water. This hot water then circulates through
a pipe to the home’s water heater tank. In summer, when the geothermal system is in the cooling mode, the desuperheater merely uses excess heat
that would otherwise be expelled to the loop. When the geothermal unit is running frequently, homeowners can obtain all of their hot water in this
manner virtually for free. A conventional water heater meets household hot water needs in winter if the desuperheater isn’t producing enough, and in
spring and fall when the geothermal system may not be operating at all.
Because geothermal systems heat water so efficiently, many manufacturers today are also offering triple function geothermal systems. Triple function
systems provide heating, cooling and hot water. They use a separate heat exchanger to meet all of a household’s hot water needs.
The Earth Connection
Once installed, the loop in a geothermal system remains out of sight beneath the Earth’s surface while it works unobtrusively to tap the heating and
cooling nature provides. The loop is made of a material that is extraordinarily durable but which allows heat to pass through efficiently. This is
important so it doesn’t retard the exchange of heat between the Earth and the fluid in the loop. Loop manufacturers typically use high-density
polyethylene, a tough plastic. When installers connect sections of pipe, they heat fuse the joints. This makes the connections stronger than the pipe
itself. Some loop manufacturers offer up to 50-year warranties. The fluid in the loop is water or an environmentally safe antifreeze solution that
circulates through the pipes in a closed system.
Another type of geothermal heating and cooling is Direct geoexchange (DX) systems, which utilize copper piping placed underground. As refrigerant is
pumped through the loop, heat is transferred directly through the copper to the earth.
To ensure good results, the piping should be installed by professionals who follow procedures established by the International Ground Source Heat
Pump Association (IGSHPA). Installers should be certified by IGSHPA or be able to show equivalent training by manufacturers or other recognized
authorities at a recognized institution, such as one of the many regional geothermal training centers located throughout the United States.
The length of the loop depends upon a number of factors, including the type of loop configuration used; a home’s heating and air conditioning load;
soil conditions; local climate; and landscaping. Larger homes with larger space conditioning requirements generally need larger loops than smaller
homes. Homes in climates where temperatures are extreme also generally require larger loops. A heat loss/heat gain analysis should be conducted
before the loop is installed.
Types of Loops
Most loops for residential geothermal systems are installed either horizontally or vertically in the ground, or submersed in water in a pond or lake. In
most cases, the fluid runs through the loop in a closed system, but open-loop systems may be used where local codes permit. Each type of loop
configuration has its own, unique advantages and disadvantages, as explained below:
Horizontal Ground Closed Loops. This configuration is usually the most cost effective when adequate yard space is available and
trenches are easy to dig. Workers use trenchers or backhoes to dig the trenches three to six feet below the ground, then lay a series of parallel plastic
pipes. They backfill the trench, taking care not to allow sharp rocks or debris to damage the pipes. Fluid runs through the pipe in a closed system. A
typical horizontal loop will be 400 to 600 feet long per ton of heating and cooling capacity. The pipe may be curled into a slinky shape in order to fit
more of it into shorter trenches, but while this reduces the amount of land space needed it may require more pipe. Horizontal ground loops are easiest
to install while a home is under construction. However, new types of digging equipment that allow horizontal boring are making it possible to retrofit
geothermal systems into existing homes with minimal disturbance to lawns. Horizontal boring machines can even allow loops to be installed under
existing buildings or driveways.
Vertical Ground Closed Loops. This type of loop configuration is ideal for homes where yard space is insufficient to permit horizontal
buildings with large heating and cooling loads, when the Earth is rocky close to the surface, or for retrofit applications where minimum disruption of
the landscaping is desired. Contractors bore vertical holes in the ground 150 to 450 feet deep. Each hole contains a single loop of pipe with a U-bend
at the bottom. After the pipe is inserted, the hole is backfilled or grouted. Each vertical pipe is then connected to a horizontal pipe, which is also
concealed underground. The horizontal pipe then carries fluid in a closed system to and from the geothermal system. Vertical loops are generally more
expensive to install, but require less piping than horizontal loops because the Earth deeper down is alternatingly cooler in summer and warmer in
winter
.
Pond Closed Loops. If a home is near a body of surface water, such as a pond or lake, this type of loop design may be the most economical.
The fluid circulates through polyethylene piping in a closed system, just as it does in the ground loops. Typically, workers run the pipe to the water,
then submerge long sections under water. The pipe may be coiled in a slinky shape to fit more of it into a given amount of space. Geothermal experts
recommend using a pond loop only if the water level never drops below six to eight feet at its lowest level to assure sufficient heat-transfer capability.
Pond loops used in a closed system result in no adverse impacts on the aquatic system.
Open Loop System. This type of loop configuration is used less frequently, but may be employed cost-effectively if ground water is plentiful.
Open loop systems, in fact, are the simplest to install and have been used successfully for decades in areas where local codes permit. In this type of
system, ground water from an aquifer is piped directly from the well to the building, where it transfers its heat to a heat pump. After it leaves the
building, the water is pumped back into the same aquifer via a second well--called a discharge well--located at a suitable distance from the first. Local
environmental officials should be consulted whenever an open loop system is being considered.
Standing Column Well System. Standing column wells, also called turbulent wells or Energy WellsTM, have become an established
technology in some regions, especially the northeastern United States. Standing wells are typically six inches in diameter and may be as deep as 1500
feet. Temperate water from the bottom of the well is withdrawn, circulated through the heat pump’s heat exchanger, and returned to the top of the
water column in the same well. Usually, the well also serves to provide potable water. However, ground water must be plentiful for a standing well
system to operate effectively. If the standing well is installed where the water table is too deep, pumping would be prohibitively costly. Under normal
circumstances, the water diverted for building (potable) use is replaced by constant-temperature ground water, which makes the system act like a
true open-loop system. If the well-water temperature climbs too high or drops too low, water can be "bled" from the system to allow ground water
to restore the well-water temperature to the normal operating range. Permitting conditions for discharging the bleed water vary from locality to
locality, but are eased by the fact that the quantities are small and the water is never treated with chemicals.
Other loop designs are also being used. In a few places, for example, home builders have installed large community loops, which are shared by all of
the homes in a housing development.
Sound Investment
Geothermal is becoming the system of choice in many parts of the United States as consumers learn more about its aesthetic advantages and long-
term value, and as it becomes more widely available.
Geothermal is no longer just for the affluent, a reputation it once held because typical early buyers were owners of upscale homes. They wanted the
quiet comfort geothermal systems provide, and they were more than willing--and could afford--to pay the cost premium associated with early
systems. This is because the extraordinarily low operating costs of geothermal systems more than make up for any higher installation costs within a
few years. According to the U.S. Environmental Protection Agency, geothermal systems save homeowners 30-70 percent in heating costs, and 20-50
percent in cooling costs, compared to conventional systems. Geothermal systems also save money in other ways. They are highly reliable, require little
maintenance, and are built to last for decades. They add considerably to the value of homes.
Today, homeowners in all income brackets can take advantage of the benefits of geothermal heating and cooling. Initial costs have declined
substantially as many more builders and heating and cooling contractors nationwide make geothermal systems available, and as innovative techniques
enable the loops to be installed more quickly (often in one day) and for lower cost.
What’s more, some electric utilities around the nation now have incentive programs and low-interest financing programs which can make geothermal
even more affordable. Many financial institutions also now allow home buyers to qualify for larger mortgages if they purchase a house that utilizes a
geothermal system. The reduction in monthly energy bills more than offsets the slightly higher mortgage payment. With such mortgages,
homeowners with geothermal systems can begin saving money from day one, then go on saving year after year!
Today, the major barrier to wider use of this marvelous technology is the fact that many consumers simply aren’t aware it’s there.
A Wise Choice
Geothermal is a smart investment for consumers who want a system that provides a high level of comfort and low monthly energy bills for as long as
they own their homes. Geothermal energy will save about 70% on your electric bill, plus the fact that home heating oil will no longer be needed.
Therefore, besides saving money on your energy bills, you will be helping the United States become independent from foreign oil!

How Geothermal Works
Your own backyard has the potential to be an energy source for heating and cooling comfort. Outdoor air temperatures fluctuate throughout the year
with the changing seasons. In contrast, ground temperatures about four to six feet below the Earth's surface remain relatively moderate and constant
all year. That's because the Earth absorbs 47% of all the heat energy that reaches it's surface from the sun. A geothermal system circulates a
water-based solution through a buried loop system to take advantage of these constant temperatures. A single piece of equipment has the ability to
heat and cool your home, while providing some or all of your home's hot water as well. Geothermal systems can save you 30% to 70% on your
monthly utility bills, plus saving the cost of home heating oil.
Heating Cycle
During the heating cycle, the fluid circulates through the loop extracting heat from the ground. The heat energy is transferred to the geothermal unit.
The unit compresses the extracted heat to a high temperature and delivers it to your home through a normal duct system or radiant heat system.
Cooling Cycle
For cooling, the process is simply reversed. Because the earth is much cooler than the air temperatures on a hot day, the geothermal system removes
heat from the home and deposits it into the ground. The fluid is cooled by the ground temperatures and returned to the unit for cooling your home.
