Antminer L7
Scrypt algorithm ASIC for mining Litecoin and Dogecoin simultaneously via merge mining
Professional-Grade Miner
This miner draws 3,425W 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 3,425W, this miner outputs approximately 11686.1 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.

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
Scrypt algorithm ASIC for mining Litecoin and Dogecoin simultaneously via merge mining
The Antminer L7 is a Scrypt cryptocurrency miner manufactured by Bitmain. It delivers a hashrate of 9050 MH/s with a power consumption of 3425W, achieving an efficiency of 378453.04 J/TH.
Built on the BM1800 ASIC chip, uses air cooling, operates at 75 dB noise level, weighs 14.4 kg, measures 400x195x290.
With a home mining score of 36/100, this miner is best suited for dedicated mining spaces for residential use. It produces 11686.1 BTU/h of heat output, making it effective for supplemental space heating.
At 378453.04 J/TH, the Antminer L7 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 11686.1 BTU/h) can be ducted into a room, turning money you would otherwise spend on heating into hashrate.
