There are already as many as 730,000 heat pumps in Finland. They extract more than 5 terawatt-hours of energy from around buildings per year. A heat pump is by far the most popular form of heating in new single-family houses, and heat pumps are rapidly replacing oil and electric heating as well as district heating in old buildings. In 2015, Finns invested approximately 350 million Euros in heat pumps, out of their own pockets.
