About SunBit

SunBit Oy sells the Bitcoin Boiler, a water-based heating system that uses waste heat from Bitcoin mining hardware to heat a building. The unit has an output of 5.3 or 10.6 kW and heats water to 60 °C, with excess heat released through an outdoor unit.

The customers are owners of detached houses and commercial properties that already have water-based heating. The offer is turnkey: SunBit handles installation, maintenance and 24/7 remote management, and the company states that mining income can offset electricity costs.

SunBit was founded in 2023 and is based in Espoo, Finland. Its reference projects include installations in Kotka and Nokia, and in 2025 it completed its first project abroad, a commercial property in Lekkum, Netherlands. The company lists Finland, the Netherlands and Belgium as its served areas.

Product: Bitcoin Boiler, a heating system that uses waste heat from Bitcoin mining hardware, sold with installation, maintenance and remote management.
