What to look for
| What matters | Why | Hashrate House |
|---|---|---|
| Noise | Air-cooled miners run 75+ dB; you'll hear them through walls | 34 dB, no fans |
| Heat use | All the power becomes heat; reusing it is where home mining pays | Heats hot water, floors, forced air, or a hot tub |
| Circuit | Real hashrate takes real power, usually 240V | 240V, 30A (often the water heater's circuit) |
| Efficiency (J/TH) | Lower means more hashrate per watt | Aqueon 19.9 J/TH; HashTub Pleb 24 or Pro 17.5 |
| Install | Who can hook it up, and with what | A plumber and an electrician, like a water heater |
| Warranty | Support if something goes wrong | 1 year from purchase, 18 months registered; 60-day money-back from delivery |
Efficiency matters, but at home the heat matters more: a slightly less efficient miner whose heat replaces your water heater can beat a more efficient one blowing heat out a window.
