Bitmain Antminer S21 XP Hyd
Latest Generation Hardware
This is the newest generation of mining hardware, featuring the most advanced ASIC chips available. Latest-gen miners deliver the highest efficiency (lowest J/TH), the best profitability per watt, and the longest profitable lifespan.
Lower J/TH means lower operating costs and more profit per hash. Cutting-edge silicon technology means this miner will remain competitive longer than older generations as network difficulty rises.
Hydro-Cooled Miner
This miner uses a closed-loop liquid cooling system (hydro cooling) instead of traditional air cooling. Water or coolant circulates through internal channels to absorb heat from the ASIC chips, then transfers it to an external radiator or facility cooling loop.
Hydro-cooled miners run significantly quieter than air-cooled models since they eliminate or minimize fan noise. They also achieve higher hashrates and better efficiency because the chips can be driven harder while staying within safe thermal limits. The trade-off: hydro miners require compatible water infrastructure — inlet/outlet connections, a cooling distribution unit (CDU), and proper plumbing.
Hydro cooling is ideal for professional mining operations and data centers where water infrastructure already exists, or for home miners building a dedicated water-cooled setup to eliminate noise completely.
Professional-Grade Miner
This miner draws 5,676W and produces 50 dB of noise — it is designed for dedicated mining environments, not living spaces. Professional-grade miners deliver the highest hashrate and revenue per unit but require proper infrastructure: a 240V circuit, adequate ventilation or exhaust ducting, and a space where noise is not a concern (garage, basement, warehouse, or outdoor enclosure).
For home miners looking for a quieter alternative, consider our Bitcoin Space Heater builds or explore open-source miners like the Bitaxe that are purpose-built for residential environments.

Frequently Asked Questions
Is the Bitmain Antminer S21 XP Hyd profitable?
At $0.07/kWh electricity, the Bitmain Antminer S21 XP Hyd generates approximately $5.58 in daily profit. Profitability depends on your electricity rate and Bitcoin network conditions. Use the calculator above with your actual electricity rate for personalized results.
Can I mine Bitcoin at home with the Bitmain Antminer S21 XP Hyd?
The Bitmain Antminer S21 XP Hyd has a home mining score of 44/100. With 50 dB noise and 5,676W power draw, it may require a dedicated space like a garage, basement, or outdoor enclosure. Consider noise insulation and proper ventilation.
Can the Bitmain Antminer S21 XP Hyd heat my home?
The Bitmain Antminer S21 XP Hyd outputs approximately 19367 BTU/hr of heat. For reference, a typical space heater produces 5,000-5,500 BTU/hr. All electrical energy consumed by the miner is converted to heat, making it 100% efficient as a heater. D-Central offers Bitcoin Space Heater builds designed specifically for home heating integration.
What power supply does the Bitmain Antminer S21 XP Hyd need?
The Bitmain Antminer S21 XP Hyd draws 5,676W of power. You need a power supply rated for at least 6,244W with appropriate voltage (200-240V AC). D-Central stocks compatible power supplies in our shop. Always use a quality PSU from a reputable manufacturer to protect your investment.
