After a decline in recent years caused by a sluggish construction sector, the economy as a whole, and inexpensive oil, heat-pump sales have improved in Finland, with over 60,000 heat pumps sold in 2016. Consumers invested 350 million
(US$ 370 million) in heat pumps last year, and the use of heat pumps in larger buildings is expanding. The total number of heat pumps installed in Finland is heading towards 800,000 units.
Finnish Heat Pump Association statistics show that annual sales of ground-source heat pumps dropped 8% to 8,500 units. With sales reaching 3,500 units in 2016, a 30% year-on-year increase, air-to-water (ATW) heat pumps were the big success story. Sales of exhaust-air heat pumps amounted to 2,200 units, a 20% year-on-year increase. The ATW heat pumps were mainly installed during renovation to replace oil or electric heating, or as an addition. Exhaust-air heat pumps are mainly installed in new single-family houses. The growth reflects enhanced heat-pump performance, excellent supply, and a changing market structure. Sales of air-source heat pumps reached 45,000 units, roughly the same level as the previous year.
