StrongU STU-U8
Quick answer
The StrongU STU-U8 is a Bitcoin miner rated about 46 TH/s at roughly 2,100 W (about 45.7 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 2,100W, 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 2,100W, this miner outputs approximately 7165 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 StrongU STU-U8 is a SHA-256 cryptocurrency miner manufactured by StrongU. It delivers a hashrate of 46 TH/s with a power consumption of 2100W, achieving an efficiency of 45.7 J/TH.
Weighs 8200 kg, measures 130 x 220 x 390mm.
With a home mining score of 11/100, this miner is best suited for dedicated mining spaces for residential use. It produces 7165 BTU/h of heat output, making it effective for supplemental space heating.
At 45.7 J/TH, the StrongU STU-U8 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 7165 BTU/h) can be ducted into a room, turning money you would otherwise spend on heating into hashrate.
