Bitmain Antminer KS5 Pro (21Th)
Professional-Grade Miner
This miner draws 3,150W and produces 75 dB of noise — it is designed for dedicated mining environments, not living spaces. Professional-grade miners deliver the highest hashrate and revenue per unit but require proper infrastructure: a 240V circuit, adequate ventilation or exhaust ducting, and a space where noise is not a concern (garage, basement, warehouse, or outdoor enclosure).
For home miners looking for a quieter alternative, consider our Bitcoin Space Heater builds or explore open-source miners like the Bitaxe that are purpose-built for residential environments.
Heater-Class Miner
At 3,150W, this miner outputs approximately 10748 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.
