Member Country Report, Market Overview, Germany – September 7, 2021. 
The Member Country Report of Germany included a market overview. Several universities, research organizations, and industrial enterprises in Germany are working on heat pump technologies. Heat pumps account for more than half of all heating systems installed in new buildings. There is even more potential in the building stock; a government scheme rewards property owners who replace older oil-fired central heating systems, which is one of the key catalysts for heat pump implementation. Air to water heat pumps currently accounts for about 80% of the market in Germany. High electricity prices compared to gas and oil, like in the UK, are a significant hurdle for heat pumps. According to their research, roughly 842,000 heating systems were installed in one year in 2020 for new and existing buildings, as well as replacement. Thanks to the government’s support system, the number of heat pump sales have increased dramatically from 100,000 in 2019 to 140,000 in 2020. Download the presentation here.
