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 way the roots of a tree exchange the essentials of life with their leaves and branches, a Bosch geothermal heat pump provides unmatched comfort and tranquility to your home and family. You will experience amazing peace and quiet, unmatched contentment and efficiency while you re Bosch geothermal system saves energy for generations to come. That s because Bosch is Invented for Life. Cooling Mode Heating Mode

4 3 Residential Geothermal Heat Pumps Operation Modes of a Heat Pump Outside, temperatures fluctuate with the changing seasons, but underground temperatures don t change nearly as dramatically, thanks to the mass of the earth. 4 to 6 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 an earth loop, and/or a pump to reinjection well, capitalizes on these constant temperatures to provide free energy.

5 boschheatingandcooling.com 4 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 reduced load for air conditioning your home.

6 5 Residential Geothermal Heat Pumps Earth Coupling Options Just like trees and plants have different root systems, there are several earth 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 Pond/Lake Loop System Well Water System

7 boschheatingandcooling.com 6 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 the 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 connected to the Bosch geothermal heat pump.

8 7 Residential Geothermal Heat Pumps 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 (Matt loops) are laid at the bottom of the excavation. The piping is connected together, and run into the home for connection to the Bosch geothermal heat pump. The excavation is backfilled, and returned to its original condition.

9 boschheatingandcooling.com 8 Pond/Lake Loop System 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.

10 9 Residential Geothermal Heat Pumps Well Water Loop System Also referred to as Pump to Reinjection or Class V Thermal Exchange Wells, these systems are often the best choice for cooling dominant climates (including residential), 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. These systems are favorable in most areas. Talk to your Bosch Geothermal representative about your particular application.

11 boschheatingandcooling.com 10 Advantages of Bosch Geothermal Systems Bosch Geothermal Systems provide among the most efficient heating and cooling efficiencies available in the world today. Being environmentally friendly has its benefits, beyond just sharing energy with the earth and saving you money considered these advantages that you get just by going geothermal: u u u You can choose to have all of your equipment indoors providing a quieter environment Storm proofing your home nothing outside to be damaged by inclement weather 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 Environmentally Friendly Bosch s green technology is one of the most environmentally friendly ways to heat and cool your home.
