Innosilicon A9 ZMaster
Heater-Class Miner
At 620W, this miner outputs approximately 2115 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.
