Waste heat replaces heating A miner in a living space heats it. Whatever gas or electricity you therefore do not buy counts against the power bill, but only in the months you would be heating anyway.

The break-even electricity price is the price per kilowatt-hour at which earnings exactly cover the power bill. Below it the machine earns, above it the machine burns money. In central Europe that is the number almost everything turns on.

The sum behind it

Power cost per day–

of which heat credit–

BTC per day = hashrate ÷ network hashrate × 144 blocks × 3.125 BTC × (1 − pool fee) Power cost = watts ÷ 1000 × 24 h × price per kWh Break-even = earnings in euro ÷ kilowatt-hours per day

Not included: connection, cooling, power-supply losses, downtime and maintenance. Water cooling adds the loop itself, hosting adds the slot fee. Network difficulty rises over the long run, which lowers earnings at the same hashrate; the payback figure uses today's values and is therefore on the optimistic side.

Assessment

The Avalon A1566 is Canaan's current mid-range at 185 TH/s and 18.5 J/TH. Canaan units are traditionally straightforward to set up and have their own, fairly approachable interface. Efficiency and price both sit mid-field, which makes it a solid rather than outstanding choice.

Do the sums before you buy

If you do not like the numbers, you are not alone: at household prices almost none of these machines pay off in central Europe. If you still want to understand how mining works economically, you can play it through in the Coinovo app, with the same models and the same formulas, but without hardware and without a power bill.
