Connecting to district heating

Households and businesses within the Oulu city, Haukipudas, Kiiminki, and Oulunsalo regions can become customers of Oulun Energia’s district heating.

In new construction areas, all properties can almost without exception be connected to district heating, as the district heating network is constantly being built alongside expanding residential and business areas. In previously built up areas, we always examine the conditions for a district heating connection on a case-by-case basis.

District heat acts as a basis for smart energy solutions—it is an investment in constantly evolving technologies.

Instructions for connecting to district heating



Oulu’s district heating network covers the entire Oulu urban area and its most important neighbouring areas of Haukipudas, Jääli, Kiiminki, and Oulunsalo. To ensure reliable heat distribution, we systematically service and overhaul the network, as well as build new network and monitor the faultlessness of the heat distribution 24/7.
