Canaan Avalon Nano 3 Review 2024: The Best Home Miner?

The Canaan Avalon Nano 3 is a compact miner and heater combo that's affordable to buy. It can hash up to 4 TH/s using only about 120 watts of power, and it's quiet too. In this review, we'll check out how it performs and whether it's worth buying.

The fifth epoch has arrived, meaning that Bitcoin's supply emission is now 50% less than before. This makes mining twice as challenging for miners. However, this decrease in supply is expected because of Bitcoin's programmed halving, which is built into its code. This change has posed a growing challenge for individual miners over the years, leading many to shut down their machines due to decreasing profitability and rising energy demands. As a result, Bitcoin mining has become predominantly the realm of professional mining farms, leading to increased centralization over time.

Recently, there has been a rise in small-scale home mining initiatives. This includes repurposing devices like the Antminer S9 into space heaters with special modifications to reduce noise, as well as projects like the Futurebit Apollo and DIY initiatives such as the "Bitaxe" open-source project. One notable addition to this trend is the Canaan Avalon Nano 3. In this review, I'll examine the Avalon Nano 3, analyzing its hashrate, energy consumption, profitability, noise level, design, and other important aspects.

Canaan Avalon Nano 3: What It Is?

Canaan Avalon Nano 3 Overview
Canaan Avalon Nano 3 Overview

The Canaan Avalon Nano 3 isn't just a Bitcoin miner; it's also a small heater for your home. It can mine Bitcoin or other SHA 256-based cryptocurrencies. In absolute terms, its hashrate isn't the most powerful (4TH/S), so you won't earn as much, but it also helps heat your house.

The fans blow out the heat from the device, with the air reaching about 60 degrees Celsius at maximum power. Domestic miners like this one are often advertised as heaters too because they serve a dual purpose. Plus, the fact that they can keep your home warm might make them more appealing to your spouse.

Canaan is a big company that's been making mining machines for a long time. They're even on Wall Street (NASDAQ: CAN). Now, they've made a home miner for the first time. They have access to the latest technology for making these machines, and they've made one that's ready to use, though it's not open-source. But you can still pick which mining pool you want to join, and you can even mine on your own if you want.

This miner has 10 chips inside that can mine a little over 4.2 terahashes per second. It uses a maximum of 140 watts of power (during our test it used a maximum of 127 watts @ max power). It's a quite efficient miner, using about 29 joules of energy for each terahash. And it's also a great deal at just $99 (a bit more if you want the power supply too). It gives you a lot of mining power for a low price and uses very little energy. Later on, we'll also look at how profitable it is compared to other options.

How The Avalon Nano 3 Works

Apart from the hashing power and low power consumption, Avalon Nano 3's main perk is its small size and built-in Wi-Fi. It weighs less than 1 kilogram and is super compact, so you can put it almost anywhere. With Wi-Fi, you can place it wherever you want without needing an Ethernet cable for internet connection like traditional ASICs.

It's all set up when you receive itβ€”just plug in the cable, connect it to Wi-Fi, choose your favorite pool, pick a preset (low, medium, or high), and start mining. No need to mess with firmware or anything else; you can do everything from your smartphone or computer.

Finding its IP address is easy tooβ€”it's right there on the little screen near the power button. This makes it perfect for beginners who want to learn about mining. Plus, since it uses roughly the same firmware as bigger miners, it's great for educational purposes too.

The Avalon Nano 3 is built to mine non-stop at full power without overheating, thanks to the fans at the back. Although, I've noticed that the included Canaan power supply unit (PSU) might get a bit too much warm.

Using the admin panel of the Nano 3, you can choose any mining pool you like, such as "stratum+tcp://," set up your worker (usually a Bitcoin address), restart the device, and it'll start mining immediately.

At maximum settings, the Nano 3 makes about 36 decibels of noise, which isn't much. But if you want it to be even quieter, you can adjust it to medium or low speed.

Canaan Avalon Nano 3 Features

What makes the Avalon Nano 3 a good choice for home miners? Let's check out the main reasons:

  1. Affordability: It's priced at around $100, making it affordable for almost everyone. Plus, you get a brand new unit with the latest ASIC chips, so you're not getting an outdated miner.
  2. Hashing Power: With 4 terahashes per second (TH/s), it's not the fastest miner out there, but it's a solid starting point, especially considering its low power consumption.
  3. Power Consumption: It uses a maximum of 140 watts of power, which is similar to what a desktop computer or monitor consumes.
  4. Form Factor: It's small and lightweight, weighing less than 1 kilogram, so you can easily move it around. It also features magnetic vent front/back covers for easy dust cleanup.
  5. Connectivity: It has Wi-Fi built-in, making it easy to place anywhere in your house without needing to connect it to an Ethernet cable. This is really convenient.
  6. Compatibility: It can mine cryptocurrencies that use the SHA-256 algorithm, like Bitcoin, and it can connect to any pool that supports Stratum V1. So you have a lot of options for what you can mine with it.

Canaan Avalon Nano 3 Design

One of the most interesting aspects of the Avalon Nano 3 isn't just the fact that you can mine at 4TH/S with just 120watts and even heat your house in the mean time, but it's how this is obtained. Let's have a look at the most important aspects.

Form Factor

The Nano 3 is light, less than one kilo. The dimensions of the Avalon Nano 3 are approximately 20.5 centimeters in length, 11.5 centimeters in width, and 5.7 centimeters in height. In American measurements, it's about 8.07 inches long, 4.53 inches wide, and 2.24 inches tall. The volume of the device it's extremely compact: 1312 cubic centimeters or 81 cubic inches.

It's small size let's it easily be put in every corner of the house. The rubber feet and perfectly squared size makes it easy to stack more devices on top of each other, in case you want to increase your hashrate with more of these devices.


The devices has a type of active airflow with three fans on the back that blows over big heatsinks positioned inside the device, by taking out the hot air in front of the device. This let's you easily point the air in the area you would like to heat at the same time. Thanks to the great built quality of the device, the heat doesn't goes around the device so except the front grille, the other exterior parts feels actually not hot at the touch.


The display might seem an overreach but it's actually useful to see the important stats of the device, such as the hashrate and the power consumption. It also tells the time. This little LCD shows also the IP address of the machine, so you won't have to use an IP scanner to locate it in your network.

Avalon Nano 3 Alternatives

The Avalon Nano 3 made by Canaan is one of the first home miners meant to heat your house while mining Bitcoin. Since it's made by a big company, there aren't really any other options like it right now. However, there are some alternatives.

  1. Antminer S9: Introduced nearly a decade ago, the Antminer S9, including variants like S9i and S9j, remains a staple in the mining community. Despite its age, it boasts a hash rate of up to approximately 14 TH/s, drawing around 1372 W (like a vacuum cleaner, basically). While its energy efficiency is not impressive at 98 J/TH, many users have repurposed it as a space heater, often tweaking and downclocking it for optimal performance. It serves as a viable alternative to the Avalon Nano 3, especially for those looking for a more serious mining setup, although it's crucial to consider energy costs before investing.
  2. Bitaxe: The Bitaxe Project offers a distinct approach, not solely focused on heating but rather as a low-power and cost-effective mining solution. Rooted in an open-source ethos, it repurposes ASIC chips, such as the BM1366 ASIC from the S19XP, into single-board configurations. Despite its modest hash rate of around 0.5 TH/s due to the use of a single chip, it excels in terms of energy efficiency, boasting an impressive 24 J/TH and consuming only 12 W. Moreover, ongoing developments promise more powerful Bitaxe solutions with multiple chips on the same board, enhancing its mining capabilities. This miner is more used as a "lottery miner" by mining in solo mode on pools like the Public Pool or the CK Pool.

Both of these alternatives are available for purchase, with worldwide shipping, through the D-Central shop. D-Central, a reputable e-commerce platform based in Canada, has established a strong track record for customer service and reliability in the mining community.
