Canaan Avalon Mini 3

Description

Avalon Mini 3

The first factory-built Bitcoin space heater that does not require a single modification. The Canaan Avalon Mini 3 is a 37.5 TH/s SHA-256 miner designed from the ground up as a home appliance — baseboard heater form factor, 33–55 dB operating range, Wi-Fi control from your phone, and four power modes that let you balance hash rate, heat output, and noise for any room in your house. Plug it in, connect the Avalon Family App, point it at your pool, and start mining Bitcoin while heating your home. No custom firmware, no fan swaps, no enclosure mods. Canaan built the dual-purpose miner that the home mining community has been asking for.

At 800W full power, the Mini 3 outputs approximately 2,730 BTU/hr — equivalent to a standard portable electric heater — while running 66 advanced 4nm ASIC chips at 21.3 J/TH efficiency. In Night Mode, it drops to ~400W and ~33 dB: quieter than a refrigerator, still hashing at ~20 TH/s, still warming your bedroom. The physics are the same as every Bitcoin space heater we sell: every watt of electricity becomes a watt of heat. The difference is that these watts also produce SHA-256 hash rate. Your heating bill stays the same. Your sats stack up.

D-Central stocks the Avalon Mini 3 in Canada with full support, warranty service, and the same expertise we bring to every miner in our catalog. We have been building and selling Bitcoin mining heaters since 2016 — we know this category better than anyone. Whether this is your first miner or your tenth, we are here for setup, troubleshooting, and repair if you ever need it.

Four Operating Modes

The Avalon Mini 3 ships with four pre-configured profiles that you switch between in the Avalon Family App. No firmware flashing, no SSH, no config files — just tap.

Mode	Hash Rate	Power	Noise	Best For
Mining	37.5 TH/s	~800W	50–55 dB	Maximum hash rate, dedicated mining room or workshop
Heater (Super)	~30 TH/s	~650W	~45 dB	Living spaces, balanced heat and hash rate
Heater (Eco)	~25 TH/s	~500W	~40 dB	Daytime use in living room, home office
Night	~20 TH/s	~400W	~33 dB	Bedrooms, quiet spaces, overnight mining

Night Mode at ~33 dB is quieter than most household appliances — comparable to a whisper or a quiet library. Even Mining Mode at 50–55 dB is roughly the volume of a normal conversation. This is not a repurposed industrial ASIC. Canaan designed this from scratch for rooms where people live and sleep.

App-Controlled Mining Heater

The Avalon Family App (iOS and Android) turns the Mini 3 into the most accessible Bitcoin miner on the market. Initial setup takes minutes: download the app, create an Avalon account, pair via Bluetooth, connect to your Wi-Fi network, enter your mining pool credentials, and start hashing. From that point, the app gives you full remote control:

• Mode switching — Toggle between Mining, Super Heater, Eco Heater, and Night modes with a tap
• Pool configuration — Set your preferred pool or switch to solo mining (Public Pool, CK Solo, or your own full node)
• Thermostat control — Set a target temperature in Heater modes; the miner adjusts power to maintain it
• Real-time monitoring — Hashrate, power consumption, chip temperature, IP address, all from your phone
• Display & night light — Toggle the on-device screen and ambient night light on or off

No web dashboards to bookmark, no IP addresses to remember, no SSH terminals. If you can use a phone app, you can run this miner. For power users who prefer a hardwired connection, Canaan offers an optional USB-to-Ethernet adapter.

Purpose-Built for Home Living Spaces

The Avalon Mini 3 uses a baseboard heater form factor — long, low, and designed to sit along a wall. At 760mm wide and 214mm tall, it occupies roughly the same footprint as a traditional electric baseboard heater. The slim profile keeps it out of the way while directing warm air upward into the room naturally.

Safety features match what you expect from a home heating appliance: tip-over protection automatically shuts the unit down if it falls, thermostat control prevents overheating by adjusting power output to maintain your target temperature, and a safety buckle on the power connector prevents accidental disconnection. The operating temperature range of -5°C to 40°C covers every Canadian scenario from a cold garage startup to a warm summer room.

Solo Mining Ready

The Avalon Mini 3 supports solo mining out of the box. Point it at Public Pool, CK Solo, or connect it directly to your own Bitcoin full node for the most sovereign mining setup possible. At 37.5 TH/s, your odds of hitting a solo block are low — but they are not zero. Every hash is a lottery ticket for a full block reward. This is what pleb mining is about: contributing your hash rate to the decentralization of the Bitcoin network on your own terms.

Prefer pooled mining? The Mini 3 works with any Stratum-compatible pool. It ships with F2Pool integration (scratch-off card included), but you can configure any pool in the app: Braiins, Ocean, Demand Pool, or whichever pool aligns with your values. See our Bitaxe Hub for more on solo mining philosophy and the open-source mining ecosystem.

The Physics: Why Every Miner Is a Heater

A 800W electric space heater converts 800W of electricity into 800W of heat. The Avalon Mini 3 converts 800W of electricity into 800W of heat and 37.5 TH/s of SHA-256 hash rate. The thermodynamics are identical — the first law of thermodynamics guarantees that every watt consumed becomes a watt of thermal energy. The only question is whether you want that watt to do one job or two.

In a Canadian winter — six or seven months where you are paying for heat anyway — running a Bitcoin miner as your space heater means your effective mining cost is zero during heating season. You were going to spend that electricity on heat regardless. The Mini 3 just adds Bitcoin production to the energy you are already consuming.

D-Central Space Heater Comparison

The Avalon Mini 3 joins D-Central’s lineup of dual-purpose Bitcoin mining heaters. Here is how it compares to our custom-built Space Heater Editions:

Model	Hash Rate	Power	BTU/hr	Noise	Best For
S9 Space Heater	~13.5 TH/s	~800–1,300W	~2,730–4,434	~45–55 dB	Entry-level, small rooms
S17 Space Heater	~40 TH/s	~1,200W	~4,094	~45–55 dB	Mid-range hash rate, medium rooms
Avalon Mini 3 (this unit)	37.5 TH/s	800W	~2,730	33–55 dB	Plug-and-play, app control, bedrooms
S19 Space Heater	~50–95 TH/s	~1,500–3,250W	~5,100–11,090	~45–55 dB	Maximum hash rate, large rooms (240V)
L7 Pivotal Edition	~3.5 GH/s	~1,300W	~4,434	~45–55 dB	Scrypt (Litecoin/Dogecoin), medium rooms

The Avalon Mini 3 advantage: It is the only miner in this lineup that ships as a finished consumer appliance. No custom firmware, no fan swaps, no enclosure builds. App control, multiple power modes, thermostat integration, and tip-over safety — all out of the box. If you want plug-and-play simplicity with genuine hash rate, this is the unit.

When to choose a D-Central custom build instead: If you need more heat output (the S19 at 240V pushes 4x the BTUs), want tunable firmware with per-chain control, or prefer Ethernet-only networking, our custom Space Heater Editions offer more raw power and deeper configurability for experienced miners.

Frequently Asked Questions

How loud is the Avalon Mini 3?

In Night Mode, approximately 33 dB — quieter than a refrigerator and comparable to a whisper. Eco Heater mode runs at roughly 40 dB (library quiet). Mining Mode at full 37.5 TH/s reaches 50–55 dB, which is about the volume of a normal conversation. For comparison, a stock industrial Antminer runs at 75+ dB. The Mini 3 was designed from the ground up for rooms where people live, work, and sleep.

Can I run this on a standard household outlet?

Yes. The Avalon Mini 3 accepts 110–240V AC with a universal integrated power supply. At full power it draws 800W — well within the capacity of a standard 15A / 120V North American outlet. No dedicated circuit, no electrician visit, no 240V wiring required. Plug it into any wall outlet and you are mining.

Will this actually heat my room?

At full power (800W), the Mini 3 outputs approximately 2,730 BTU/hr — equivalent to a standard portable electric space heater. Canaan rates it to warm a small to medium room (~80 sq ft as primary heat) in about 10 minutes. In Eco or Night modes at lower wattage, heat output decreases proportionally. For larger rooms or as the sole heat source in a Canadian winter, consider supplementing with additional heating or stepping up to our S19 Space Heater Edition which delivers up to 11,090 BTU/hr. Use our BTU calculator to size for your space.

Can I solo mine with the Avalon Mini 3?

Yes. The Mini 3 supports any Stratum-compatible pool, including solo mining pools like Public Pool and CK Solo. You can also point it at your own Bitcoin full node for a fully sovereign setup. At 37.5 TH/s, solo block odds are low — but every hash is a chance at a full block reward. Many customers run the Mini 3 on a solo pool during heating season and switch to pooled mining in warmer months. Every hash counts.

Do I need a separate power supply?

No. Unlike most ASIC miners that require a separate APW-series PSU, the Avalon Mini 3 has a fully integrated power supply. Plug the included power cable directly into the wall. This is one of the key design advantages over traditional miners: no external PSU, no heavy transformer brick, no extra cables to manage.

How do I set it up?

Download the Avalon Family App on your phone, create an Avalon account, and power on the Mini 3. The app discovers the device via Bluetooth and walks you through Wi-Fi setup and pool configuration. The entire process takes about 5–10 minutes. No command line, no web interface, no technical expertise required. For pool mining, you can use the included F2Pool scratch-off card or configure any pool of your choice in the app.

What happens in summer when I do not need heat?

You have options. Run it in Night Mode (~400W, ~33 dB) for minimal heat with continued hash rate production. Move it to a garage, basement, or utility space with adequate ventilation. Or shut it down until heating season returns — it is just an appliance. Some customers keep it running year-round in a room with a window fan exhausting warm air. The dual-purpose advantage is strongest in winter, but the miner works whenever you want it to.

How does the Avalon Mini 3 compare to a Bitaxe?

Different tools for different goals. A Bitaxe runs at 0.5–3 TH/s on 5–25W — it is a desktop solo lottery miner and a statement of decentralization. The Avalon Mini 3 at 37.5 TH/s and 800W is a serious SHA-256 machine that doubles as a space heater. The Bitaxe is about participation and sovereignty at minimal cost. The Mini 3 is about meaningful hash rate and replacing your electric heater with a machine that mines Bitcoin. Many of our customers run both — a Bitaxe on the desk and a Mini 3 heating the room.
