StrongU STU-U2
Professional-Grade Miner
This miner draws 1,600W 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 1,600W, this miner outputs approximately 5459 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.
Profitability Calculator
| Period | Revenue | Electricity Cost | Profit |
|---|---|---|---|
| Daily | $0.22 | $2.69 | $-2.46 |
| Weekly | $1.57 | $18.82 | $-17.25 |
| Monthly | $6.73 | $80.64 | $-73.91 |
| Yearly | $81.89 | $981.12 | $-899.23 |
Heating offset estimates the value of heat replacing an electric space heater during heating season (~6 months/year in Canada). Actual savings depend on your heating setup and climate.

Frequently Asked Questions
Is the StrongU STU-U2 profitable?
At $0.07/kWh, the StrongU STU-U2 currently operates at a daily loss of $2.46. 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 StrongU STU-U2?
The StrongU STU-U2 has a home mining score of 28/100. With 0 dB noise and 1,600W power draw, it may require a dedicated space like a garage, basement, or outdoor enclosure. Consider noise insulation and proper ventilation.
Can the StrongU STU-U2 heat my home?
The StrongU STU-U2 outputs approximately 5459 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 StrongU STU-U2 need?
The StrongU STU-U2 draws 1,600W of power. You need a power supply rated for at least 1,760W 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.
