SunBit Deploys 30 Bitcoin Mining Heating Systems Across Finland

Finnish startup SunBit has operationalized 30 Bitcoin mining heating systems, with 29 situated in Finland. The liquid-cooled Bitcoin Boiler units redirect thermal output into hydronic heating loops, delivering between 5.3 kW and 10.6 kW of capacity with equipment priced from €14,500 to €22,300 before VAT. Economically, the setup requires Bitcoin to trade near $70,000 to fully cover operational electricity expenses, projecting an estimated capital payback period of three to six years. The deployment accompanies larger Nordic heat-reuse initiatives, including MARA Holdings supplying heat to networks serving 80,000 residents.
