Canaan AvalonMiner 821
Réponse rapide
The Canaan AvalonMiner 821 is a Bitcoin miner rated about 11.5 TH/s at roughly 1,200 W (about 104.3 J/TH). An industrial-class unit — loud and power-hungry, best suited to a dedicated mining space, not living areas.
Heater-Class Miner
At 1,200W, this miner outputs approximately 4094 BTU/hr of heat — equivalent to a standard electric space heater. Every watt consumed by an ASIC miner is converted to heat with 100% efficiency, making it a space heater that also mines Bitcoin.
During heating season, miner heat can offset part of the heat a room would otherwise need from another electric heater. The economics depend on your electricity rate, room heat demand, BTC price, network difficulty, and noise constraints.
