SunBit, a Finnish company, has installed 30 systems that use heat from Bitcoin mining to warm buildings, with mining revenue potentially covering electricity costs.

The systems cost roughly $20,000 or more to install and use more electricity than heat pumps, making their financial advantage dependent on Bitcoin prices, power costs and mining competition.

Bitcoin’s expected 2028 halving will cut new coin rewards in half, potentially before homeowners recoup their investment, and is not included in SunBit’s payback calculations.

Finland is already the testbed for heating with mining. MARA’s systems feed waste heat from its miners into district heating networks in Satakunta and Seinäjoki, warming about 80,000 residents.
