About the Antminer S21e Hydro
The Antminer S21e Hydro is the entry model of Bitmain's S21 hydro range, for sites with cheap power that want the quiet and the density of a water loop more than the last joule per terahash. In this factory version it runs at 288 TH/s on 4,896 W, which is 17.0 J/TH; the 332 and 310 TH/s versions keep that efficiency at 5,644 and 5,270 W. Within the range, the S21 Hydro and the S21+ Hydro are more efficient, the XP models more so.
It needs three phase power at 380 to 415 V and draws about 117.5 kWh a day per unit. Cooling runs through a liquid loop with manifold plumbing and a dry cooler or water source; the site also provides power cords and a PDU. At about 50 dB it is far quieter than air cooled machines, and the operating range is 5 to 45 °C. Each unit measures 339 × 173 × 207 mm and weighs 13.8 kg, the chassis of the S21+ Hydro.

Read before you buy the Antminer S21e Hydro
The breakeven power price, and why we ask for yours first
Every machine has an electricity price above which it stops making money. Work that number out and most of the hardware decision answers itself.
Hydro miners compared, and what the loop really costs
Water cooled machines hold the efficiency frontier and they are quiet enough to put near people. They also come with a construction project attached, and that is the part to price before the hardware.
Three phase power for a mining site, in plain terms
Most modern miners are three phase machines, and most new sites are wired for something else. This is the vocabulary you need before you talk to an electrician.
