Bitmain Antminer S21 XP Hydro 473 TH/s Hydro Cooled Bitcoin Miner: Specifications, Single Phase Advantage, and Deployment Guide

The S21 XP Hydro combines specifications that sound like they belong to different machines. Quiet like a home miner at 40 dB. Powerful at 473 TH/s, nearly half a petahash from a single unit. Flexible on voltage with universal 100 to 240V single phase input. No other Bitcoin miner currently available delivers all three in one package.

The key differentiator is single phase compatibility. Bitmain's more powerful hydro models (S23 Hyd at 580 TH/s, S23 Hyd 3U at 1,160 TH/s) require 380V+ three phase industrial power. The S21 XP Hydro runs on the same standard single phase circuits available in homes, offices, and small commercial spaces worldwide. At 220V it draws approximately 25.8 amps, requiring a dedicated 30 amp circuit. At 110V it draws about 51.6 amps, which is impractical for most installations, so 220V+ is the realistic minimum for this unit.

12.0 J/TH efficiency sits between the air cooled S21 XP (13.5 J/TH) and the S23 Hyd 3U (9.5 J/TH). The S21 XP Hydro is 11 percent more efficient than its air cooled sibling at 75 percent more hashrate, which demonstrates the performance headroom water cooling unlocks from the same chip architecture. Each unit adds roughly 5.7 kW to your cooling loop, so size heat exchangers and pumps accordingly.

Water cooled closed loop using standard plumbing. No dielectric fluid immersion. The miner itself has zero internal fans. All noise comes from the external cooling infrastructure (pumps, radiators, dry coolers), which you control and can isolate from working spaces. 40 dB at the unit is realistic when the cooling loop equipment is properly located.

Daily electricity at $0.07 per kWh: approximately $9.54. Monthly: $286. At $0.04 per kWh industrial rates: $5.45 daily, $163 monthly. Current Bitcoin revenue at 473 TH/s runs approximately $16 to $18 per day, netting $7 to $12 in daily profit depending on your power rate.

410 x 170 x 209 mm at 13.8 kg. Compact hydro chassis smaller than any air cooled Antminer at this hashrate. Ethernet connectivity. Bitmain firmware with web management, fleet tools, and standard Stratum for all SHA-256 pools. 5 to 45 degrees Celsius at 5 to 95 percent humidity.

MillionMiner ships the S21 XP Hydro brand new with Bitmain warranty, PSU, and power cables included. Free DDP delivery worldwide. Hosting at managed facilities with existing hydro loops available for operators who want water cooled mining returns without building their own cooling infrastructure.

Antminer S21 XP Hydro 473 TH/s: The Single Phase Hydro Powerhouse

The S21 XP Hydro fills a gap no other Bitmain product covers: hydro cooled Bitcoin mining at 473 TH/s on universal single phase 100 to 240V power. The larger S23 Hyd 3U produces 1,160 TH/s but demands 380V+ three phase and runs 50 dB. The S21 XP Hydro sacrifices raw hashrate but retains single phase compatibility and delivers 10 dB less noise at 40 dB. For facilities with water cooling infrastructure but only single phase power, this is the highest output Bitmain option available.

12.0 J/TH efficiency positions the S21 XP Hydro between the air cooled S21 XP (13.5 J/TH) and the S23 Hyd 3U (9.5 J/TH). Not the current efficiency leader, but significantly better than any air cooled model and competitive for its power class. At 220V the unit draws approximately 25.8 amps, requiring a dedicated 30 amp circuit per unit. Water cooled closed loop with standard plumbing and no dielectric fluid.

410 x 170 x 209 mm at 13.8 kg. Zero internal fans means the 40 dB noise comes from your external cooling infrastructure, not the miner itself. 5 to 45 degrees Celsius. PSU and power cables included. Bitmain warranty and free DDP from MillionMiner.

473 TH/s of SHA-256 at 5,428W with hydro cooling. 11.5 J/TH efficiency — among the best in the industry, bridging the gap between the air-cooled S21 XP (13.5 J/TH) and the S23 Hydro (9.5 J/TH).

The S23 Hydro delivers 580 TH/s at 9.5 J/TH — more hashrate and better efficiency. The S21 XP Hydro at 473 TH/s and 11.5 J/TH offers a strong mid-range option, potentially at a lower acquisition cost.

At $0.07/kWh, the S21 XP Hydro generates daily profit that varies with market conditions. Check the live profitability calculator on this page for current numbers at your electricity rate. At predicted 2026 BTC prices of $150K-$250K, daily profits could increase significantly. Solid profitability for hydro-equipped facilities.
