About the Bosch Group

Sharing Energy with the Earth

Bosch Geothermal Systems bring

your home in harmony with nature,

while providing unmatched energy

efficiency at a price that can’t be

beat. Our geothermal systems

work in concert with the stable

earth temperatures to provide

heating in the winter, and cooling

in the summer.

Much like the way the roots of a

tree exchange the essentials of life

with their leaves and branches,

a Bosch geothermal heat pump

provides superior comfort and a

more tranquil environment to your

home and family via our system’s

smooth operation and consistent

temperatures. You will experience

amazing peace and tranquility,

and efficiency while your Bosch

geothermal system saves energy

for generations to come. That’s

because Bosch is Invented for Life.

Bosch Geothermal Heat Pumps


Outside, temperatures fluctuate with the changing

seasons, but underground temperatures don’t change

nearly as dramatically, thanks to the mass of the earth.

Four to eight feet below the ground, the temperature

remains relatively constant year round. A Bosch

geothermal system, which typically consists of an indoor

heat pump and a buried system of pipes called a ground

loop, and/or a well system, capitalizes on these constant

temperatures to provide “free” energy.

Operation Modes of a Heat Pump


Winter: Heating Mode

In winter time, fluid circulating through the earth loop (or well) absorbs stored heat from the ground and carries it indoors. The Bosch geothermal heat pump compresses the heat to a higher temperature and distributes it throughout the home.

Summer: Cooling Mode

In summer time, the process reverses, and the cooler earth absorbs the heat from the home, returning cooler fluid to the Bosch geothermal heat pump. This fluid is typically cooler than the outside temperatures, providing a more efficient operation and energy savings.


Earth Coupling Options

Just like trees and plants have different root systems, there are several coupling options to fit

different climates, geologies, and lifestyles. Your Bosch geothermal expert will know which works

best for you.

Vertical Ground Loop System Horizontal Ground Loop System

Pond/Lake Loop System


Well Water System


Vertical Ground Loop System

Vertical Ground Loops are perhaps the most common earth coupling system, primarily because they make good use of limited space. Holes are drilled into the earth, and then a pair of High Density Polyethylene (HDPE) pipes, connected by a “U” bend at the bottom are inserted into each hole. The bore holes are sealed with an environmentally safe grout material to enhance the transfer of heat to and from the earth, and to protect the subterranean environment. The underground pipes are connected together and run neatly into the home and are connected to a Bosch geothermal heat pump.


Horizontal Ground Loop System

Horizontal ground loops are often less expensive to install, but need more surface area. Rather than drilling, trenchers or excavators are used to dig 4 to 6 feet deep (or more), and loop variations ranging from single pipes to slinky style are laid at the bottom of the excavation. The piping is connected together, and run into the home for connection to a Bosch geothermal heat pump. The excavation is backfilled, and returned to its original condition.



Pond loops are often the least expensive application as a geothermal source. Though bodies of surface water fluctuate with ambient temperatures, these fluctuations are not as marked as actual ambient temperatures. This application is well-suited in situations where the body of water is large enough, and where boating, fishing, or other activities do not pose a risk to the loops. Pond loops can provide advantages to marine life.


Well Water Loop System

Also referred to as “Pump to Reinjection” or “Class V Thermal Exchange Well”, these systems are often the best choice for cooling dominant climates (including residential) where the warm climate predominantly requires cooling, and commercial applications. A pair of boreholes is drilled, one as the source well, and one as the injection well, and the water is pumped from the aquifer through the geothermal heat pumps, and injected back into the aquifer with no chemical change. Talk to your Bosch Geothermal representative about your particular application.


Advantages of Bosch Geothermal Systems

Environmentally FriendlyBosch’s green technology is one of the most environmentally friendly ways to heat and cool your home. The system has no direct carbon dioxide emissions, and with only positive effects on the environment. Bosch’s geothermal installations reduce greenhouse gas emissions to improve our world’s climate.

Reliability and Unmatched QualityThe ground loop/well system often lasts for generations, and your Bosch geothermal heat pump is built for the long haul. We are so confident that we back each residential heat pump with a limited warranty on all parts and labor up to 10 years! Visit boschheatingandcooling.com for specific heat pump warranties and details.

Being Green Means Saving GreenGreen is beautiful, and Bosch geothermal’s attractive environmental benefits accent our commitment to a reduction of energy consumption and elimination of carbon emissions. Geothermal HVAC systems are recognized by the US Department of Energy as the most efficient heating and cooling available, and with uncapped 30% tax credits through 2016 on the entire installation costs of your Bosch geothermal heat pump system, your savings are compounded.

Quiet OperationSynonymous with environmental friendliness, Bosch has a vested commitment to your family’s peace and tranquility. Our geothermal heat pumps are engineered to be quiet, which helps to provide a peaceful home environment.

Bosch Geothermal Systems provide some of the most efficient heating and cooling available in the

world today. Being environmentally friendly has its benefits. Beyond sharing the abundant thermal

energy stored within the earth and saving you money, considered these advantages that you get just by

going to geothermal:

u You can choose to have all of your equipment indoors – providing a quieter environment

u Storm proofing your home and HVAC system – nothing outside to be damaged by inclement weather

u Longer-lasting comfort – because equipment is safe inside, and your loop or well can last for generations to come

u No more burning of fossil fuels for heating – geothermal heat pumps can provide all the heat needed for your home

u Superior comfort for both heating and cooling modes – better humidity removal in the summer for a crisp, cool environment; more even and comfortable heating in the winter, for a cozy feel

u Thermal load sharing – you can use waste heat for your domestic hot water, pool and spa

Comparison of Energy Sources


Geothermal HVAC systems are recognized by the US Department of Energy as the most efficient heating

and cooling available, and with an uncapped 30% U.S. Federal tax credit available through 2016 for the

entire installation costs of your Bosch geothermal heat pump system, your savings are compounded.

Bosch geothermal systems are among the longest lasting, most efficient technologies available for

heating and cooling. So while they cost a little more to install the first time (because of the geothermal

loop/well), the payback period and return on investment can be rapid. With an energy consumption

reduction of 25% to 70% depending on the differing climatic regions and installation comparisons, you

will likely find no better return on your investment.

Limited Residential WarrantyCoverage for your Geothermal Heat PumpWith the limited residential warranty, you receive peace-of-mind knowing you will receive replacement parts protection for up to 10 years. This standard offering covers all components incorporated into the unit cabinet at the time of manufacture. Other components or parts that are purchased from Bosch and installed in the field have a 1 year replacement parts warranty from proof of certificate of occupancy date or proof of certified start up date, unless otherwise noted. Many units also come with a standard 10 year labor-allowance included for the replacement of any defective component to help offset labor expenses if a component should fail. Visit boschheatingandcooling.com for specific heat pump warranties and details.

30% Tax Credit for Geothermal Heat PumpsHome owners who install ENERGY STAR qualified geothermal heat pumps are eligible for a 30% tax credit on the cost of the geothermal system including all installation costs. There is no cap on the federal tax credit. Presently, these tax credits are only available through the end of 2016.

Additionally, many areas have local incentives for utilities, counties or states. Visit the DOE’s “Database of State Incentives for Renewable Energy” (DSIRE) at dsireusa.org to find out just what is in store for you!
