Bitcoin Heater 2026 – Quiet ≤45 dB Miners from €1,379

What a Bitcoin heater is

A Bitcoin heater is an ASIC miner designed for quiet operation and heat output in living spaces. Physically almost all input power becomes heat — exactly like a fan heater, except Bitcoin is mined at the same time. The difference from a standard miner is noise, enclosure and power class.

The units compared

• Avalon Q: 90 TH/s at 1,674 W (18.6 J/TH) — current efficiency, suitable for living spaces
• Avalon Mini3 Heater: 37.5 TH/s at 1,200 W (32 J/TH) — smaller heat output, cheaper entry
• Classic large miner: 3 kW and 75 dB — basement, workshop or hall only

Making the economics work

The maths works when you need the heat anyway. Then you compare mining revenue against the cost of your other heating energy rather than against electricity cost outright. A 1.67 kW unit produces roughly the heat of a mid-size fan heater, and the mining revenue lowers your effective heating cost.

The key question is summer: what happens outside the heating season? Either switch off, move it to a cool room, or reduce power.

Buying a Bitcoin heater: price and delivery

The Avalon Q sells for €1,379 including VAT and sits in our warehouse in Bavaria; the Avalon Mini3 is the smaller, cheaper option. Both ship in 2–4 business days, inside the EU with no customs and no import VAT.

You need a standard socket on an adequately fused circuit, Wi-Fi or LAN and a pool account. Setup usually takes under 30 minutes.

Safety in living spaces – children and pets

A Bitcoin heater in a living room follows the same rules as any other heater: free-standing, away from curtains and furniture, air intakes never covered. The casing gets warm but not glowing hot — still, with toddlers and pets treat it exactly like a fan heater and do not run it unattended within reach.

Units such as the Avalon Q are built for living spaces and run at ≤45 dB, roughly the level of a quiet fridge. Classic large miners at 70–75 dB belong in a basement, workshop or hall only.

What works in practice: a dedicated fused circuit, a non-flammable surface, regular dust checks on the fans and — where children play — a fixed corner that is off the play area.

Shipping, warehouse and delivery time

Stocked units ship within 2–4 business days from our warehouse in Bavaria, Germany. Because the hardware is already imported and cleared inside the EU, there is no import VAT, no customs paperwork and no waiting for air freight from Asia. Models sourced directly from the factory show their own delivery time on the product page.

We ship insured to Germany, Austria, Switzerland and the rest of the EU. Orders above 1,000 € ship free within Germany, and express shipping is available for stocked units.

Payment, invoice and warranty

You can pay by bank transfer, credit card, PayPal, Apple Pay or cryptocurrency. Every order comes with a proper invoice showing VAT. EU business customers with a valid VAT ID are invoiced at 0 % under the reverse-charge scheme, and we can switch your session to B2B mode with net prices.

New and used miners are covered by statutory warranty under EU law. Used units are tested, cleaned and shipped with a logged hashrate; the exact scope is stated on each product page.

Advice before you buy

We help you check electricity tariff, power connection, cooling, noise and realistic payback before you order — including when the honest answer is that a machine will not pay off at your kWh price. Send us your electricity cost and the planned location and we will run the numbers with you.
