Avalon A1446
Mid-range Canaan offering at 135 TH/s. Competitive efficiency at 24.5 J/TH. Standard air-cooled Avalon form factor.
Professional-Grade Miner
This miner draws 3,310W 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 3,310W, this miner outputs approximately 11293.7 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, the electricity cost of running this miner replaces your heating bill — and you earn Bitcoin on top. In cold climates like Canada, this dual-purpose approach can dramatically improve mining economics. D-Central offers purpose-built Bitcoin Space Heater editions with noise reduction, duct adapters, and heater-mode firmware for seamless home integration.

Frequently Asked Questions
Is the Avalon A1446 profitable?
At $0.07/kWh, the Avalon A1446 currently operates at a daily loss of $1.32. However, profitability can improve with lower electricity rates or rising BTC prices. If used as a space heater, the heating offset may make it economically viable.
Can I mine Bitcoin at home with the Avalon A1446?
The Avalon A1446 has a home mining score of 36/100. With 75 dB noise and 3,310W power draw, it may require a dedicated space like a garage, basement, or outdoor enclosure. Consider noise insulation and proper ventilation.
Can the Avalon A1446 heat my home?
The Avalon A1446 outputs approximately 11293.7 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. D-Central offers Bitcoin Space Heater builds designed specifically for home heating integration.
Does D-Central repair the Avalon A1446?
Yes, D-Central provides professional repair services for the Avalon A1446. Our technicians have repaired 2,500+ miners since 2016. Services include hashboard repair, control board diagnostics, fan replacement, and full refurbishment. Ship your miner to our Laval, Quebec facility for diagnosis and repair.
What power supply does the Avalon A1446 need?
The Avalon A1446 draws 3,310W of power. You need a power supply rated for at least 3,641W with appropriate voltage (200-240V AC). D-Central stocks compatible power supplies in our shop. Always use a quality PSU from a reputable manufacturer to protect your investment.
