Heat pump sales increased by 30% and even more in euro terms. More than EUR 600 million was invested in the 98,000 heat pumps that were installed last year. At the same time, the milestone of one million installed heat pumps was broken. Heat pump investments already total approximately 6 billion. Heat pumps produce well over 10 TWh of energy per year in total, which corresponds to 15% of the heating of Finland’s residential and service building stock. It is noteworthy that this huge investment in the environment and in fighting against climate change has been made primarily by house owners using their own money. The excellent profitability of heat pumps has certainly made consumers’ decision-making easier.
