GMO miner B2
Quick answer
The GMO miner B2 is a Bitcoin miner rated about 24 TH/s at roughly 1,950 W (about 81.3 J/TH). An industrial-class unit — loud and power-hungry, best suited to a dedicated mining space, not living areas.
Professional-Grade Miner
This miner draws 1,950W, but this profile does not have a verified noise value. Do not substitute a generic dB estimate; verify the exact manufacturer manual and installation requirements before choosing a circuit or location.
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 1,950W, this miner outputs approximately 6653 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.

Home Mining Assessment
The GMO miner B2 is a SHA-256 cryptocurrency miner manufactured by GMO miner. It delivers a hashrate of 24 TH/s with a power consumption of 1950W, achieving an efficiency of 81.3 J/TH.
With a home mining score of 11/100, this miner is best suited for dedicated mining spaces for residential use. It produces 6653 BTU/h of heat output, making it effective for supplemental space heating.
At 81.3 J/TH, the GMO miner B2 sits in the legacy efficiency tier, so it is most economical run as a space heater or for hobby and learning setups rather than for pure profit.
Its waste heat (around 6653 BTU/h) can be ducted into a room, turning money you would otherwise spend on heating into hashrate.
