E-Heat has completed a containerized data center in the Kirkkokallio eco-industrial park, Honkajoki, Western Finland, which is now integrated into the local district heating network. The 1MW facility will provide waste heat to heat water to 80°C (176°F) for the Vatajankoski district heating network.

The previous Puistotie grate boiler has been shut down and will serve as a backup. Vatajankoski also deployed a 2MW data center in Kankaanpää in 2024, which meets 20% of local heating needs. Last year, they launched a 1.5MW module in Merikarvia. E-Heat plans to install a 1.8MW module in Ivalo, Finnish Lapland, in spring 2026, in collaboration with Inergia Lämpö Oy, covering half of that area's heating requirements.
