Heat pumps make use of the warmth available in the environment in order to raise ambient heat to a higher, usable level. Sources of heat are the solar and geothermal energy present in the air and groundwater. The latter is used most frequently.

Gas for the Environment - The Heat Pump

E.ON Energie undertook a field test to evaluate the environmental compatibility and cost of heat pumps. The findings clearly show that heat pumps are a boon to our climate as they harbor substantial potential for reducing CO2.

Moreover, they are affordable, convenient, and assist in conserving valuable resources such as oil, coal and gas, which would otherwise be used for heating applications.

And This is How it Works

Heat pumps work much like refrigerators, albeit turning the method used in refrigerators upside down: They convert regenerative low-temperature ambient warmth into high-temperature heat. This is done by extracting the energy stored in the ambient environment, combining it with the drive energy, and transferring it as heat to the heating and hot water cycle. Approximately three fourths of the warmth used in heating appliances come from the environment. This makes heat pumps extremely efficient, environmentally compatible heating systems.
