21energy is the stronger choice for UK buyers in 2026. The Austrian manufacturing, UK reseller support through Sento, broader product range (including 12 ASIC miners), and slightly lower entry price all tip the balance. Both are excellent products — but 21energy offers more for the UK market.
Heatbit pricing and specs are approximate and subject to change. Always check the official Heatbit website for current UK pricing and availability. 21energy products are ordered through Sento as UK reseller at official 21energy prices. Updated March 2026.
