A cryptomining device manufacturer has developed a portable data center that redirects residual heat from Bitcoin mining into municipal heating grids.

Latvia-based Power Mining estimates that one of its data center modules, which are housed inside a shipping container, can mine up to 9.7 Bitcoin per year while heating around 2,000 homes.

The first two units will be shipped to an unnamed town in Scandinavia, where they will provide the municipality with 1.52MWph.

The data centers, which start from €300,000 ($349,000), each contain eight server closets with 20 Whatsminer M63S++ mining rigs.

Dielectric fluid that is warmed up in the server closets is pumped to a 1.7MW heat exchanger that then redistributes the data center’s heat to the town’s heating grid.

“We’re truly grateful to our partners for trusting us with such an ambitious and technically demanding project,” Power Mining wrote in a statement.

“We hope this is only the beginning – an opportunity to scale this model further and demonstrate how Bitcoin mining can strengthen a town’s heating system, reduce waste, and deliver real, tangible value for local communities.”

Data centers currently account for more than three percent of Europe’s electricity consumption, according to figures from the European Commission, with that figure expected to significantly increase in the coming years.

Under the EU’s latest Energy Efficiency Directive, data center operators are encouraged to reuse heat waste to supply local networks. 

With an estimated electricity consumption of around 150TWh annually, European data centers hold the potential to heat up to 10 million households if heat energy is collected and redirected into heating, according to Power Mining.

“The development of a passive heating data center is one step towards increased energy efficiency in Bitcoin mining,” the company said.

“While classical data centers can collect heat at approximately 27°C (80.6°F), the Power Mining data centers can collect heat up to 65°C ( 149°F), providing cities with more efficient sources of heat.”

Power Mining said that it is currently focused on developing these heat recapture technologies in order to further integrate them with centralized heating grids.

The company has built and shipped more than 100 shipping container data centers since it was founded in 2017, surpassing €5 million ($5.82m) in annual revenue in 2025.
