Heat pumps (DE-UZ 230)

The heat pump is a key technology for moving away from fossil fuel heating systems and is used not only for space heating but also for producing hot water. The use of regenerative heat sources (e.g. water, geothermal energy and air) saves fossil fuels. Nevertheless, there is still considerable potential for reducing the environmental impact of heat pumps. The Blue Angel requirements are therefore designed in a way that combines the absence of fluorinated refrigerants with energy-efficient operation of the heat pumps to reduce their greenhouse gas emissions. In addition, the formation of long-lasting degradation products of refrigerants (PFAS) is avoided and noise emissions are limited.
