Power Mining, one of the world’s leading personal Bitcoin mining device manufacturers, has developed a portable datacenter that will heat towns using residual heat from Bitcoin mining. The first two datacenters, housed in shipping containers, will be shipped to a Scandinavian town, where they will be connected to the municipal heating system.
In one year, one Power Mining datacenter can mine up to 9.7 Bitcoin, and heat up to 2000 homes. With 1.6MW/h in power, the datacenter achieves 95% energy efficiency, thereby providing the municipality with 1.52MW/h. The datacenters are built in Latvia and cost starting from 300,000 EUR. Due to being put together in a shipping container, they are easily shipped around the world.
The datacenter is made up of eight server closets, each outfitted with 20 Whatsminer M63S++ servers that consumes 10kW of electricity each, and creates an equivalent amount of heat. The servers can raise the incoming coolant temperature by 10-14°C, producing the equivalent amount of heat while mining Bitcoin. Each server closet is equipped with warm and cool fluid collectors, which send the warmed liquid to a built-in heat pump station, where a 1.7 MW heat exchanger ensures the redistribution of heat from the datacenter to the town’s heating grid.
If the heating grid does not require additional heat from the datacenter, the heated fluid is redirected to a built-in dry cooler, which adjusts the temperature to suit the needs of the servers. This way, the datacenter is able to cool itself, and also contributes to balancing the municipality’s heating grid.
“We’re truly grateful to our partners for trusting us with such an ambitious and technically demanding project. 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.”
The development of a passive heating datacenter is one step towards increased energy efficiency in Bitcoin mining. While classical datacenters can collect heat at approx. 27°C, the Power Mining datacenters can collect heat up to 65°C, providing cities with more efficient sources of heat.
European data centers already make up more than 3% of the continent’s total electricity consumption, which is expected to surpass 150 Tw/h annually – an equivalent of all of Poland’s electricity demands. Up to 40% of this energy is turned into heat, which most often is released into the atmosphere. If this energy were collected and redirected back to heating, it could ensure up to 10 million European households with heat. Heat collection from data centers could become one of the most effective ways to combine digitalisation and climate goals.
In addition to having built over 100 Bitcoin datacenters, Power Mining also builds personal and industrial-scale Bitcoin mining hardware. Their desktop miner is one of the most used open-source Bitcoin mining devices globally, with over 20,000 devices shipped around the world.
