What it could earn
Costs about $52/mo more than it earns at $0.15
Heat you'd pay for anyway: about $87/mo
Estimate: what a 800 W electric space heater would cost running 24/7 at $0.15/kWh. It only counts if you'd heat the room with electric heat anyway; a heat pump or gas is usually cheaper.
Break-even power price: about $0.062/kWh
Above this price the power costs more than the pool estimate.
Estimate. Changes with Bitcoin price and network difficulty. Uses BTC ≈ $84,417, network ≈ 1,057 EH/s and the seller-stated hashrate, minus a 2% pool fee and a 10% safety margin, rounded down. Updated Oct 21, 2026 15:50 UTC. Solo vs pool

Good to know
About the Avalon Mini 3
The Avalon Mini 3 is a heater miner shaped like a baseboard heater. Sellers state 37.5 TH/s at up to 800 W, so it heats a room like a mid-size electric heater while it mines. Sellers list app control and several modes (for example a quieter night mode and an extra-heat mode).
Best for: Someone who already heats a room with electricity in winter and would rather that heat also mine Bitcoin.
Check before you buy
- At about 800 W it runs on a normal household outlet, but don't share that circuit with other big heaters.
- Noise depends on the mode: sellers list roughly 33 to 55 dB.
- D-Central prices it in Canadian dollars and ships from Canada, so US import costs may apply. Our dollar figure is an estimate.

How much heat does the Avalon Mini 3 give off?
Almost all the electricity a miner uses comes out as heat, like an electric space heater. At full power that's about 800 W, or roughly 2,730 BTU per hour. How heater miners work.
Will the Avalon Mini 3 pay for its electricity?
Usually not all of it, and nothing is guaranteed. Pointed at a mining pool, it earns small, steady amounts of bitcoin that can offset part of the power bill. How much depends on Bitcoin's price, the network's total hashrate and your electricity rate, and all three change. Pointed at solo mining, it's a lottery ticket for a whole block.
