Quick answer
The Innosilicon A4 Dominator is a Scrypt miner rated about 280 MH/s at roughly 1,050 W. An industrial-class unit — loud and power-hungry, best suited to a dedicated mining space, not living areas.
Heater-Class Miner
At 1,050W, this miner outputs approximately 3583 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.

Dedicated 120V circuit recommended
The Innosilicon A4 Dominator is a Scrypt cryptocurrency miner manufactured by Innosilicon. It delivers a hashrate of 280 MH/s with a power consumption of 1050W, achieving an efficiency of 3750000 J/TH.
With a home mining score of 22/100, this miner is best suited for dedicated mining spaces for residential use. It produces 3583 BTU/h of heat output, making it suitable for supplemental space heating.
At 3750000 J/TH, the Innosilicon A4 Dominator 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 3583 BTU/h) can be ducted into a room, turning money you would otherwise spend on heating into hashrate.
Frequently Asked Questions
What are the current mining economics for the Innosilicon A4 Dominator?
At $0.07/kWh, the Innosilicon A4 Dominator currently shows an estimated daily net cost of $1.76 before pool fees and hardware cost. Lower electricity rates, network changes, BTC price changes, or useful heat recovery can change the result.
Can I mine Bitcoin at home with the Innosilicon A4 Dominator?
The Innosilicon A4 Dominator has a home mining score of 22/100. With 0 dB noise and 1,050W power draw, it may require a dedicated space like a garage, basement, or outdoor enclosure. Consider noise insulation and proper ventilation.
Can the Innosilicon A4 Dominator heat my home?
The Innosilicon A4 Dominator outputs approximately 3583 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.
What power supply does the Innosilicon A4 Dominator need?
The Innosilicon A4 Dominator draws 1,050W of power. You need a power supply rated for at least 1,155W with appropriate voltage (200-240V AC). D-Central stocks compatible power supplies in our shop.
