Bitmain Antminer L3+ (504Mh)
Heater-Class Miner
At 800W, this miner outputs approximately 2730 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.
Profitability Calculator
| Period | Revenue | Electricity Cost | Profit |
|---|---|---|---|
| Daily | $0.00 | $1.34 | $-1.34 |
| Weekly | $0.00 | $9.41 | $-9.41 |
| Monthly | $0.00 | $40.32 | $-40.32 |
| Yearly | $0.01 | $490.56 | $-490.55 |
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.

Custom Power Profiles
With custom firmware like DCENT_OS, this miner can be tuned across a wide range of power levels. Lower wattage improves efficiency and reduces electricity costs; higher wattage increases hashrate at the expense of efficiency.
| Wattage | Hashrate | Efficiency |
|---|---|---|
| 450 W | 350 MH/s | 1.29 J/MH |
| 550 W | 420 MH/s | 1.31 J/MH |
| 650 W | 480 MH/s | 1.35 J/MH |
| 800 W | 504 MH/s | 1.59 J/MH |
| 900 W | 560 MH/s | 1.61 J/MH |
| 1,000 W | 620 MH/s | 1.61 J/MH |
Actual performance varies by individual unit silicon quality, ambient temperature, and cooling configuration. These operating points are achievable with custom tuning firmware such as DCENT_OS; values are calculated at runtime by the autotuner, not fixed presets.
Home Mining Assessment
The Bitmain Antminer L3+ (504Mh) is a Scrypt cryptocurrency miner manufactured by Bitmain. It delivers a hashrate of 504 MH/s with a power consumption of 800W, achieving an efficiency of 1587301.6 J/TH.
Weighs 4400 kg, measures 188 x 130 x 352mm.
With a home mining score of 30/100, this miner is best suited for dedicated mining spaces for residential use. It produces 2730 BTU/h of heat output, making it suitable for supplemental space heating.
At 1587301.6 J/TH, the Bitmain Antminer L3+ (504Mh) 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 2730 BTU/h) can be ducted into a room, turning money you would otherwise spend on heating into hashrate.
