First heat recovery unit delivered to Tampere pilot district (March 2014)

Heat recovery systems are becoming increasingly popular in apartment blocks equipped with mechanical air extraction. These include buildings constructed between 1960 and 2000. Since 2002, heat recovery has been required by construction regulations. Heat recovery from extraction air creates cost savings of 30-40% in heating of buildings with district heating, and up to over 50% savings in buildings with oil heating.
