Obelisk SC1
Quick answer
The Obelisk SC1 is a Blake2b miner rated about 550 GH/s at roughly 500 W. Runnable at home with proper airflow and noise control; best in a dedicated space.
Heater-Class Miner
At 500W, this miner outputs approximately 1706 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.
