Bosch Geothermal

Geothermal & Water Source Systems

Bosch's heat pump systems are the most energy and cost efficient systems on the market and therefore the greenest technology and the smartest investment for commercial and residential heating and cooling applications.

Geothermal Systems

As the cost of energy increases geothermal installations become the system of choice. The earth has a tremendous capacity for storing thermal energy which can be utilized to heat or cool a Heat Pumps, Air to Air, HVAC, Geothermalbuilding or home. Although the initial cost of a geothermal application may be higher, if one considers the life cycle savings in energy and the reduced maintenance costs, then geothermal is the smartest decision for your project. Geothermal systems are especially recommended in areas that have significant heating and cooling loads. In areas that are either cooling or heating dominant our hybrid systems could be the perfect solution for your needs. Using a cooling tower in conjunction with a ground loop in areas that have a cooling dominant load reduces the cost of the loop field with only a small impact on the efficiency of the system. Conversely, in areas that are heating dominant, the addition of a boiler to a geothermal loop reduces the loop field cost with a minimal effect on the efficiency of the system.

Water Source Cooling Tower/Boiler Systems

A tower/boiler system offers as excellent alternative to a geothermal system where space is limited or initial costs are a determinant factor. The tower/boiler system consists of a cooling tower that will reject heat absorbed by the loop when the system is predominantly in the cooling mode. The boiler's function is to add heat to the loop when there is a net heating demand. In many instances the heat generated by the units in cooling mode balance the heat loss in the loop for the units in the heating mode. In this situation neither the tower nor boiler will operate as the system is self balancing. Environmental stewardship is a core philosophy for Bosch Manufacturing from design to production to the reduction in our customer's energy bills. At Bosch, we are working on a better future every day.

Advantages of Bosch's Technology Low Installation Costs

Bosch water source heat pumps systems provide the most flexible and lowest installation costs of virtually any HVAC system. In a typical installation the water loop remains above the dew point of the ambient air meaning no insulation is required on piping, a major cost of any installation. To accomplish the same degree of flexibility as a heat pump system, a four pipe system is required. This represents another significant cost saving potential since heat pump installations only require a two pipe system for either heating or cooling.

Flexibility and Comfort

Bosch units come in a wide variety of models, sizes and configurations. This provides the design engineer true flexibility when designing the system. Should the occupancy of an area change, the unit may be changed out for the appropriate size without major modifications to the layout.

Energy Efficient

Bosch units operate individually with high efficiency making the complete system extremely efficient. What makes this system unique is the ability to transfer heat around the building in winter through the common water loop. In today's modern buildings, interior zones generally require cooling even in the winter because of the lighting, occupancy and electronic loading. When cooling these areas heat is transferred to the water loop and utilized by the units on the perimeter that may require heating. This is the only system with this capability and the net result is a truly economical operating system. Individual units serve specific zones so that there is no need to operate large units if there is only a small area calling for heating or cooling.


The building is not dependent on one or two large chillers. With multiple units serving individual zones should one unit fail, only this area is affected. Bosch units are designed for convenient, easy and fast service and do not require specialized training to maintain or repair. Downtime should be minimal. Routine maintenance is limited to filter replacement and an annual checkup, making maintenance costs for water source heat pumps one of the lowest of any system.

Space Savings

Bosch horizontal units are designed to be as compact as possible. In a commercial application units are typically located above a false ceiling meaning that large equipment rooms that would normally house large chillers or air handlers are not required This frees up space that can now be used for tenant occupancy generating additional revenue throughout the life of the building. Each Bosch unit will have its own duct system to serve the specific zone. Large central plant ducting is not required, allowing for the possibility of reduced floor to floor height with a corresponding reduction in the mass and cost of the building.

Operation Modes of A Heat Pump

Cooling Mode

Geothermal Air Conditioning Systems

Cooling Mode

In the COOLING mode, the refrigerant, a hot gas, is pumped from the compressor to the water-to-refrigerant heat exchanger via the reversing valve. Water, generally with an anti freeze, following through the water-to-refrigerant heat exchanger removes heat and the hot gas condenses into a liquid. This liquid then flows through a metering device to the air-to-refrigerant heat exchanger coil. In evaporating into a gas, the liquid absorbs heat and cools and dehumidifies the air that passes over the coil surface. The cooling cycle is completed when the surface. The cooling cycle is completed when the reversing valve and back to the suction side of the compressor.

Heating Mode

During the HEATING mode, the refrigerant, a hot gas, is pumped from the compressor to the air-to-refrigerant heat exchanger coil via the reversing valve. In the air-to-refrigerant heat exchanger coil, the heat is removed by the air that passes over the coil surface, and the hot gas condenses into a liquid. The air is circulated to the space and provides heating for the building. The refrigerant liquid then flows through a metering system to the water-to-refrigerant heat exchanger. While it evaporates into a gas, the liquid absorbs heat and cools the water. The heating cycle is completed when the refrigerant \ufb02ows as a low pressure gas through the reversing valve and back to the suction side of the compressor.

Earth Coupling Options

Geothermal systems use the earth as a heat source. In order to transfer heat to or from the house, heat exchangers (ground loops) are installed in the ground. These consist of high density polyethylene plastic pipes. The loops are then connected to the heat pump and fluid is circulated between them transferring the heat between the heat pump and the earth.

Vertical Ground Loop System

Geothermal Vertical Ground Loop This type is used mainly in commercial buildings or where space is limited. Vertical holes 100 to 400 feet deep are drilled in the ground, and a single loop of pipe with a U-tube at the bottom is installed. The borehole is then sealed with grout to ensure good contact with the soil. The vertical ground loops are then connected to a horizontal underground header pipe that carries fluid to the unit. The earth's temperature is more stable farther below the surface which is an advantage for the system. Vertical ground loop fields may be located under buildings or parking lots. The life expectancy is in excess of 50 years.

Horizontal Ground Loop System

Geothermal Horizontal Ground Loop

This type of design is cost effective on smaller projects or where there is sufficient space for the loop. Trenches, three to six feet deep, are created and a series of parallel plastic pipes are laid inside them. These loops are manifolded and connected to the heat pump. The fluid is then circulated, absorbing or rejecting heat to the earth depending on the mode of operation. A typical horizontal loop will be 400 to 600 feet long for each ton of heating and cooling but will vary according to the soil type and the layout of the piping.

Pond/Lake Loop System

Geothermal Pond Lake Loop System

This type of design is economical when a project is located near a body of water. Fluid circulates through polyethylene piping in a closed system, just as it does through ground loops but in this case underwater. The pipes may be coiled in a slinky to fit more surfaces into a given amount of space. The lake needs to be a minimum size and depth depending on the load. Lake loops have no adverse impact on the aquatic system.

Well Water System

Geothermal Well Water System

This type of installation is only possible if there is sufficient ground water available in a well, a lake or river in the area. The water must be of good quality. Local codes may limit the use of this system in certain areas. The system is open which means that water is pumped directly into the geothermal unit and then discharged either into a return well or a body of water. The water quality is unaffected other than a change in the temperature.
