Home mining

According to the manufacturers, quiet home miners produce roughly 33–55 dB. The quietest machines (Avalon Nano 3S, Bitaxe) are around 33–35 dB – like a quiet library. Machines around 45–50 dB (Avalon Q, DG Home 1) sound roughly like a muted conversation – better suited to a study, hallway or plant room. A classic ASIC produces 70–80 dB and doesn't belong in a flat without a soundproof box. You'll find the values for all machines in the table above.

A miner turns practically all the electricity it uses into heat: 1 kWh of electricity gives roughly 1 kWh of heat, just like an electric heater. A machine drawing 800 W therefore heats like an 800 W convector – and mines as well. A heat pump produces heat more cheaply, so a miner makes sense mainly where you would otherwise heat directly with electricity. See the calculation in our article Heating with an ASIC miner.

Calculate the current as power ÷ 230 V. Machines up to roughly 1.7 kW can be handled by a normal socket on a circuit with a 16 A breaker, but a kettle, oven or washing machine shouldn't run on the same circuit. For 24-hour operation don't use more than about 80% of the breaker rating, and don't use extension leads or multi-plug adapters. A warm socket or a tripping breaker means the circuit is overloaded – move the miner elsewhere or consult an electrician.

It mainly depends on the price per kWh. Home miners such as the Avalon Mini 3, Avalon Q or DG Home 1 would pay for themselves at roughly 1.6–1.9 Kč/kWh (at difficulty and exchange rate as of 18 Oct 2026). At normal grid prices of 4.5–6.5 Kč/kWh they mine less than they consume – so they make sense as heating or for surplus solar power.

We give a 24-month warranty on new home miners. We handle warranty claims and repairs in our own ASIC miner service centre in Prague 10 (Rostovská 260/2b, Mon–Fri 9–17) – you can bring the machine in person or send it to us. We also repair machines out of warranty. More on the ASIC miner repairs page.

Yes. If the noise, summer heat or electricity price at home stops suiting you, we can arrange to move the machine to our hosting in a data centre with cheaper electricity. Home miners are built for quiet operation rather than maximum efficiency, though – so we'll calculate in advance whether the particular machine pays off in hosting. Locations and prices are on the ASIC miner hosting page.
