The device input is separate from the external adapter’s mains input. Check the matching adapter, cable and regional mains lead for your exact unit.
Electricity example: £0.25/kWh and 24 hours of operation are fixed assumptions. The energy and cost rows use the listed watts; actual consumption depends on mode and setup. Include any extra adapter or auxiliary load when it is outside that rating. These rows show electricity cost, not mining income or useful room heat.
Enter your own tariff, fees and operating assumptions in the Bitcoin mining calculator. Assess how much paid heating is replaced in the heat-reuse guide.
Load current specifications into the calculator: Nano 3 · Nano 3S. Then enter your own costs and running time.

Manufacturer references checked 29 October 2026: Canaan Nano 3, Canaan Nano 3S shop specification and Nano 3S features and test notes. These are published ratings, not measurements from The Mining Shop. The comparison’s efficiency is the listed product value. Its energy and cost rows are arithmetic examples, not measured consumption or guaranteed operating results.
Noise, power supply and network differences
Canaan’s Nano 3S feature page advertises 30–40 dB and identifies 30 dB as a low-mode test at 25°C; its shop lists 33–40 dB. The Nano 3 laboratory range uses different published conditions. These figures do not establish which machine is quieter in your room. Ask for sound measured at a stated distance and power mode, including the adapter and background noise.
The Nano 3S uses a supplied USB Wi-Fi module, with limited support for some USB-to-RJ45 adapters. Canaan does not guarantee every adapter or USB hub. A generic industrial-miner Ethernet specification is not proof of a built-in Ethernet socket on this device. Match the exact unit and firmware to its manufacturer setup instructions.
Confirm the adapter, compatible cable and UK mains lead included with your particular order. The required 28V PD supply should not be confused with an arbitrary phone charger. Manufacturer package descriptions do not establish what is included in every reseller bundle.
Which Nano should you choose?
- For learning: compare the complete delivered kit and support, then check that your chosen pool’s fees and payout threshold suit small hashrate.
- For mining output: the 3S reference offers more hashrate per watt, but the extra purchase cost still needs to be justified using your own assumptions.
- For desk warmth: start with room heat demand and tolerable sound. A higher hashrate at the same power does not make more useful heat.
- If you already own a Nano 3: compare the upgrade cost with the additional expected mining output. There is no automatic financial case for replacing a working unit.
Use the model-specific calculator links above to load the current listed hashrate and power, then enter your actual electricity rate, fees and running time. Measured wall power and operating mode can differ from a listed rating. For solo mining, use the solo mining calculator; a small average expected payout does not mean a regular solo payout.
Check the current Nano 3 listing and Nano 3S listing for availability and order terms. For a larger heat source, see the separate Nano 3S, Mini 3 and Avalon Q comparison and the home heating cost example.
Canaan Avalon Home miners in simple English
A Nano turns a modest electrical load into heat while attempting SHA-256 mining work. Check the exact Nano generation and operating mode; larger Avalon machines have different power and room requirements.
Simple example
Match the adapter’s output, cable and connector to the exact miner, then check its mains input and regional lead. A familiar-looking USB connector alone does not establish compatibility.
Key terms in plain English
- ASIC:
- A computer built to do one specialised job. A mining ASIC is designed for a particular proof-of-work algorithm.
- Hashrate:
- The amount of mining work a machine attempts each second. More hashrate does not guarantee more profit.
- Efficiency:
- How much electricity a miner uses for a set amount of work. Lower joules per terahash usually means better efficiency.
- Wall power:
- The electricity measured at the socket or supply. It includes losses that a headline chip figure may leave out.
- Mining pool:
- A service that combines work from many miners and shares rewards using stated rules.
Start with the exact model
A manufacturer name tells you who made a machine. It does not tell you whether that machine suits your power supply, cooling system, noise limit or mining plan. Two models from the same brand can have very different needs.
Write down the full model name and rated version. Check the algorithm, hashrate, wall power and efficiency. Then compare those figures with the seller’s description and current manufacturer information.
Compare hashrate and efficiency
Hashrate is the amount of mining work attempted each second. Efficiency shows how much electricity is used for that work. A higher hashrate can still be a poor choice if the power cost is too high.
Use measured wall power when it is available. A chip or test-mode figure may leave out fans, pumps or power-supply losses. Test worse conditions as well as the headline setting.
Check the electrical supply
ASIC miners are continuous electrical loads. Confirm voltage, current, plug, cable, isolation, earthing and protective devices before installation. A competent electrician should assess the real circuit and duty cycle.
Do not choose a miner first and hope the room can support it later. Electrical work, cooling and noise control can change the true project cost.
Plan heat and noise
Nearly all electricity used by a miner becomes heat. The room needs a safe path for cool air to enter and hot air to leave. Hydro and immersion systems still need pumps, heat exchangers and a place to reject heat.
Noise data also needs context. Fan speed changes with temperature and load. Test the machine in conditions similar to the planned site.
Check firmware and controls
Use firmware from a trusted source. Match it to the exact control board and hardware revision. Keep a record of the original version and the steps needed to recover the machine.
Change default passwords. Restrict dashboard access. Check the pool address and payout wallet before the full test. Watch accepted shares, rejects, temperature, fan speed and restarts.
Warranty, repairs and spare parts
Read the written warranty instead of relying on a sales headline. Check the length of cover, exclusions, shipping responsibility and the evidence needed for a claim. Ask how repairs are handled in the UK.
Spare-part access matters after the warranty ends. Confirm whether fans, power supplies, control boards and hashboards can be identified and tested.
A simple buying example
Imagine two miners with similar hashrate. One uses less electricity, but needs expensive electrical and cooling work. The other uses more power, but already fits the site. The better choice depends on the complete installed cost and expected running cost.
Now test lower revenue, higher difficulty and downtime. If the plan fails after a small change, it has little room for error.
Questions to ask before paying
- What is the exact model, revision and serial-number evidence?
- Which algorithm and firmware branch does it use?
- What is the measured wall power at the stated mode?
- What voltage, current, cooling and network setup are required?
- Who handles delivery damage, warranty work and later repairs?
Frequently asked questions
What is the difference between Avalon Nano 3 and Nano 3S?
The Nano 3S has a 6 TH/s reference hashrate versus up to 4 TH/s for the Nano 3. Both have a published 140W maximum. Compare the complete kit, operating mode and setup requirements as well as hashrate.
How much electricity does a Nano use in the UK?
At a constant 140W, 24 hours uses 3.36 kWh. An illustrative £0.25/kWh rate gives £0.84/day. Use your actual tariff and measured wall power; this does not establish mining profit.
Can a Nano mine a solo Bitcoin block?
It can attempt mining through a compatible solo setup, but a successful block is very unlikely over short periods at this hashrate. Use the solo calculator for probability, and check the selected pool’s current rules and fees.
Will a Nano heat an entire room?
Around 140W is a small supplementary heat source. Whether any heat is useful depends on the room’s losses, existing heating and operating hours. Do not assume a kilowatt-scale heating effect.
Is stock in the Nano comparison current?
The comparison uses each product page’s stock message and checks again every 30 seconds while the page is visible, with another check when you return to the tab. Check the displayed time and current order terms before buying. If a refresh fails, previous values are hidden.
Does the device-input voltage mean mains voltage?
No. The miner’s DC device input and the external adapter’s AC mains input are different requirements. Use an adapter, cable and connector compatible with the exact miner, and check the regional mains lead and supply. Do not choose a charger from wattage or connector appearance alone.
Can I load either Nano into the calculator?
Yes. The model links above load the current listed hashrate and watts into the Bitcoin mining calculator. Enter your own electricity rate, pool fee, uptime and other costs, then check the market timestamp. A listed rating and an estimate are not measurements or a payout promise.
Which Nano will be quieter in my room?
The published figures use different conditions and do not establish a direct room comparison. Fan mode, temperature, placement, background sound and distance affect what you hear. Check the exact manufacturer conditions and assess the intended operating position before relying on either in a sound-sensitive room.
Conclusion
Canaan Avalon Home: Noise, Heat and Setup should help you compare a specific machine. Check the model, power, efficiency, site needs, firmware, support and full cost. A brand name by itself is never enough.
