Common questions about buying a miner

Do I pay customs when ordering from 21energy?
<p>No. All our miners ship from our warehouse in Austria. Customers inside the EU (including Germany, Austria, France, Finland, Sweden, and more) pay no customs or import duties. The shop price is the final price.</p><p>Customers outside the EU will pay country-specific import duties on delivery, we only display the net price for such orders.</p>
How long does shipping to Germany, Austria, or Switzerland take?
<p>In-stock miners typically arrive within 2–3 business days across the DACH region.</p><p>For pre-orders or custom configurations, the expected lead time is stated directly on the product page. All orders over €200 inside the EU qualify for free shipping.</p>
What warranty do I get on my ASIC miner?
<p>All new, originally packaged ASIC miners we sell come with a 12-month warranty, provided the operating conditions (ambient temperature, power supply, no overclocking) are observed.</p><p>Repairs or replacements are handled directly through our European support, no return to China or the US required.</p>
Can I use any miner as a heater?
<p>Technically, every ASIC miner converts ~100% of its electricity into heat, that is the physical reality. For residential heating use, we recommend our Ofen 2 series: insulated housing, quiet operation, designed as furniture, and a control app.</p><p>Plain ASIC miners (e.g. Antminer S21) can also be used as a heat source for basements, offices, or workshops, but they are louder and less living-room friendly.</p>
Which payment methods does 21energy accept?
<p>We accept SEPA transfer, credit and debit cards (Visa, Mastercard), Apple Pay, Google Pay, Klarna (pay-over-time), and of course Bitcoin.</p><p>For B2B orders and larger quantities, we offer custom payment terms, contact our business team for details.</p>
