Heat pumps are considered as easy to use while utilizing the possibility of bringing low-temperature heat sources to a higher temperature. Thus, low-grade renewable energy sources (such as air, water, ground, solar), as well as waste heat sources, can be used to reduce the demand for fossil fuels and greenhouse gas emissions.
How does a heat pump work?
Heat pumps are devices that use electricity or other energy sources to extract heat from a low-temperature source (such as the air, ground, or water) and transfer it to a high-temperature source (such as a building or a hot water tank).
