Ranked by our Home Mining Score — noise, power, heat value, and ease of setup.
Choosing the right miner for your home means balancing noise, power draw, heat output, and hashrate. Our Home Mining Score weighs these factors so you can find the perfect miner for your living space. These rankings update automatically with live market data.
A single-chip Bitmain ASIC (~1.2 TH/s, ~18W, near-silent) you can run on a desk. Open-source, repairable, and hand-built by D-Central in Canada — 2,600+ shipped since 2016.
25 miners in our database qualify for this list under the page's filter criteria. Efficiency spans 15.0 to 765.7 J/TH — the Bitaxe Gamma is the most power-efficient of the group. The quietest pick here is the NerdQAxe+ at 25 dB. At a $0.0735/kWh rate, the NerdQAxe++ posts the strongest daily profit at $0.02/day. For heat output, the Canaan Avalon Nano 3 tops the list at 4,777 BTU/hr — enough to heat ~150 sq ft.

Miners are ranked by Home Mining Score (highest first). Profitability is calculated server-side using live BTC price and network difficulty, with a default electricity rate of $0.0735/kWh (Quebec average). Daily revenue uses the standard formula: (hashrate x 10^12 x 86,400 x block_reward) / (difficulty x 2^32). You can adjust the electricity rate above to recalculate profitability for your location.
All data comes from our ASIC Miner Database. Scores, specs, and profitability update automatically. Only miners meeting this page's filter criteria are shown.
A good home miner balances noise level (under 50 dB for living spaces), power draw (standard 120V outlet compatible), and heat output that can offset heating costs in winter. Our Home Mining Score weighs all these factors.
Yes — low-noise miners like the Bitaxe and NerdAxe run at under 45 dB and draw minimal power. They are ideal for apartments. Full-size ASICs require dedicated space and ventilation.
It varies widely. A Bitaxe uses about 15W (like a light bulb), while an Antminer S21 draws 3,500W. Use our Power Cost Calculator to estimate your monthly electricity cost.
Profitability depends on your electricity rate and hardware choice. At Quebec rates ($0.0735/kWh), efficient miners like the S21 are profitable. Use our Profitability Calculator for live estimates.
Yes — 100% of the electricity consumed by a miner is converted to heat. A 3,000W miner produces over 10,000 BTU/hr, equivalent to a portable electric heater, while earning Bitcoin.
25 miners currently meet this page's criteria. The Bitaxe Ultra ranks first by home mining score. Rankings recompute automatically as our ASIC Miner Database is updated, so this list stays current.
Efficiency on this list ranges from 15.0 J/TH to 765.7 J/TH. Lower J/TH means less electricity per unit of hashrate — at scale, that gap compounds into a meaningful difference in your monthly power bill.
