Bitmain Antminer G2
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, the electricity cost of running this miner replaces your heating bill — and you earn Bitcoin on top. In cold climates like Canada, this dual-purpose approach can dramatically improve mining economics. D-Central offers purpose-built Bitcoin Space Heater editions with noise reduction, duct adapters, and heater-mode firmware for seamless home integration.

Frequently Asked Questions
Is the Bitmain Antminer G2 profitable?
At $0.07/kWh, the Bitmain Antminer G2 currently operates at a daily loss of $2.02. However, profitability can improve with lower electricity rates or rising BTC prices. If used as a space heater, the heating offset may make it economically viable.
Can I mine Bitcoin at home with the Bitmain Antminer G2?
The Bitmain Antminer G2 has a home mining score of 31/100. With 0 dB noise and 1,200W power draw, it may require a dedicated space like a garage, basement, or outdoor enclosure. Consider noise insulation and proper ventilation.
Can the Bitmain Antminer G2 heat my home?
The Bitmain Antminer G2 outputs approximately 4094 BTU/hr of heat. For reference, a typical space heater produces 5,000-5,500 BTU/hr. All electrical energy consumed by the miner is converted to heat, making it 100% efficient as a heater. D-Central offers Bitcoin Space Heater builds designed specifically for home heating integration.
What power supply does the Bitmain Antminer G2 need?
The Bitmain Antminer G2 draws 1,200W of power. You need a power supply rated for at least 1,320W with appropriate voltage (200-240V AC). D-Central stocks compatible power supplies in our shop. Always use a quality PSU from a reputable manufacturer to protect your investment.
