# Innosilicon A4+ LTCMaster

The Innosilicon A4+ LTCMaster is a Scrypt miner rated about 620 MH/s at roughly 750 W. An industrial-class unit — loud and power-hungry, best suited to a dedicated mining space, not living areas.

### Heater-Class Miner

At 750W, this miner outputs approximately 2559 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. This means it serves as a space heater that also mines Bitcoin.

The economics depend on your electricity rate, room heat demand, BTC price, network difficulty, and noise constraints.

| Period  | Revenue | Electricity Cost | Profit   |
