Description
Canaan Avalon A15 Pro 221TH/s Bitcoin Miner
The Canaan Avalon A15 Pro is a professional SHA-256 ASIC miner developed for Bitcoin mining farms, hosting facilities, workshops, and other dedicated mining environments. Canaan’s current official A15Pro configuration delivers a rated hashrate of 221TH/s while consuming approximately 3,662W.
With a rated power efficiency of 16.8J/TH, the Canaan Avalon A15 Pro provides a strong balance between Bitcoin mining output, electrical demand, and conventional air-cooled deployment. Two high-speed 12050 fans move cooling air through the chassis to remove heat from the hashboards, controller, power supply, and internal components.
The Canaan Avalon A15 Pro operates on the SHA-256 algorithm and is primarily intended for Bitcoin mining. It may also work with other compatible SHA-256 cryptocurrencies where suitable firmware, wallets, and mining pools are available.
This is industrial mining equipment rather than a quiet household appliance. Its 3.66kW electrical load, maximum 75dB noise level, and continuous heat output require a properly rated electrical circuit, strong ventilation, wired networking, and suitable noise separation.

Canaan Avalon A15 Pro Bitcoin Mining Performance
The Canaan Avalon A15 Pro delivers a factory-rated 221TH/s of SHA-256 mining output. This level of performance is intended for continuous professional operation rather than casual desktop use.
Actual accepted hashrate can vary according to ambient temperature, electrical stability, fan condition, firmware, network latency, pool uptime, dust buildup, and individual manufacturing tolerance.
Operators should compare the local miner dashboard with pool-side accepted hashrate over several hours or days. Short-term dashboard peaks do not always represent long-term accepted performance.
Important metrics include:
- Real-time and average hashrate
- Accepted and rejected shares
- Hashboard status
- ASIC chip errors
- Fan speed
- Intake and exhaust temperature
- Power consumption
- Pool latency
- Network uptime
A persistent reduction in output may indicate blocked airflow, high intake temperature, unstable power, a failed fan, pool interruption, firmware problems, or a hashboard fault.
Canaan Avalon A15 Pro 16.8J/TH Efficiency
The official efficiency rating of the Canaan Avalon A15 Pro is 16.8 joules per terahash. Dividing 3,662W by 221TH/s gives a calculated result of approximately 16.57J/TH, which is consistent with Canaan’s rounded factory specification.
At 3,662W, continuous operation consumes approximately:
- 87.89kWh per day
- 615.22kWh per week
- 2,636.64kWh per 30-day month
- 32,080kWh per year
Estimated monthly miner-only electricity costs are:
- At $0.04/kWh: approximately $105.47
- At $0.06/kWh: approximately $158.20
- At $0.08/kWh: approximately $210.93
- At $0.10/kWh: approximately $263.66
- At $0.15/kWh: approximately $395.50
- At $0.20/kWh: approximately $527.33
These calculations exclude routers, extraction fans, air conditioning, transformers, power-distribution losses, and other facility equipment.
Bitcoin mining profitability is not guaranteed. Bitcoin price, network difficulty, block rewards, transaction fees, pool charges, electricity rates, equipment cost, cooling expenses, maintenance, and uptime all affect returns.
Canaan Avalon A15 Pro Cooling and Noise
The Canaan Avalon A15 Pro uses two 12050 fans to force cooling air through the miner. Air passes across the hashboards, heatsinks, controller, and power components before leaving the exhaust side as heated air.
Canaan lists a maximum sound level of approximately 75dB. This makes the machine unsuitable for bedrooms, living rooms, shared offices, and other quiet environments.
Airflow Requirements
- Keep both intake and exhaust openings unobstructed.
- Do not install the miner inside a sealed cabinet.
- Prevent hot exhaust from returning to the intake.
- Use intake filtration in dusty environments.
- Provide sufficient clearance around both ends.
- Use extraction fans or ducting where required.
- Monitor room and intake temperature.
- Stop the miner if either fan fails.
The Canaan Avalon A15 Pro converts nearly all of its electrical consumption into heat. A 3,662W miner therefore produces a continuous thermal load comparable to a powerful electric heater.
Any noise-control enclosure must preserve adequate airflow. Restricting ventilation can increase temperature, reduce hashrate, raise fan speed, and damage the miner.
Mineable Coins with Canaan Avalon A15 Pro
Bitcoin
The primary cryptocurrency mined by the Canaan Avalon A15 Pro is Bitcoin. The miner performs SHA-256 calculations and submits accepted shares to a compatible mining pool.
Other SHA-256 cryptocurrencies may also be technically supported where suitable firmware, pools, wallets, and exchange liquidity are available.
Before switching networks, compare mining difficulty, expected revenue, pool support, wallet compatibility, block rewards, and market liquidity.
For general information about Bitcoin and proof-of-work mining, review the official Bitcoin educational resources.
Canaan Avalon A15 Pro Mining-Pool Setup
The Canaan Avalon A15 Pro will normally be configured to work with a professional SHA-256 mining pool. Pool mining combines the hashrate of many machines and distributes rewards according to accepted shares and the chosen payment method.
Before selecting a pool, compare:
- Pool fees
- Payout thresholds
- Payment methods
- Server locations
- Historical uptime
- Security controls
- Reporting tools
- Backup server support
Configuration usually requires a pool URL, worker name, password, and payout address. Secondary and tertiary pools should be entered where supported to reduce downtime.
Third-party services such as NiceHash may accept compatible SHA-256 hashrate, but fees, payout structures, regional availability, and profitability should be reviewed before use.
Canaan Avalon A15 Pro Electrical Requirements
The seller-supplied voltage range for the Canaan Avalon A15 Pro is 220–277V. The exact input range and connector should be confirmed from the delivered machine’s power-supply label and official documentation.
At approximately 3,662W, estimated current draw is:
- Approximately 16.65A at 220V
- Approximately 15.26A at 240V
- Approximately 13.22A at 277V
These calculations do not include power-factor effects, manufacturing tolerance, startup variation, or circuit derating.
- Use a properly grounded high-voltage circuit.
- Install a correctly rated breaker.
- Use appropriate conductor sizes.
- Confirm the required power connector and cable.
- Use overcurrent and surge protection.
- Avoid overloaded extension leads.
