Bitmain Antminer S19 Hydro

The Bitmain Antminer S19 Hydro (commonly the 158 TH/s variant, released October 2022) is a hydro-cooled (liquid-cooled) Bitcoin ASIC miner from Bitmain’s popular S19 series. It’s designed for professional mining operations, using the SHA-256 algorithm for Bitcoin (BTC), Bitcoin Cash (BCH), and Bitcoin SV (BSV). The liquid cooling provides quiet operation, excellent thermal management (inlet water 20–50°C, outlet up to 70°C), and sustained high performance in dense racks or hot environments, without the high fan noise of air-cooled models.

Here are detailed views of the Antminer S19 Hydro, showing its compact rectangular black chassis, hydro cooling ports (inlet/outlet fittings), sturdy build, and rack-friendly design:

Key Specifications (158 TH/s Variant – Most Common)

• Hashrate: 158 TH/s (±5%; some batches 145–158 TH/s)
• Power Consumption: 5451 W (±10%; typical wall power)
• Efficiency: ~34.5 J/TH (good for its era, though newer models like S19 XP Hydro are better at ~21 J/TH)
• Algorithm: SHA-256 (BTC/BCH/BSV)
• Cooling: Hydro/liquid cooling (requires external loop with distilled water + inhibitor/antifreeze; low noise ~50 dB)
• Noise Level: ~50 dB (significantly quieter than air-cooled S19 equivalents)
• Dimensions: 412 × 197 × 209 mm (compact for rack mounting)
• Weight: ~15.8 kg
• Power Input: 220–240V AC (standard; high amperage circuit needed)
• Connectivity: Ethernet RJ45 (web interface for pool setup/monitoring)
• Operating Conditions: Temp 5–40°C ambient, humidity 10–90%
• Other Features: Plug-and-play for pools; supports firmware updates; robust for 24/7 farms

Features and Use Case

This is an industrial/professional-grade miner — excellent for farms or data centers with hydro infrastructure (pumps, radiators, coolant management). The liquid cooling eliminates fan noise/throttling issues, allowing stable operation in warm climates or dense racks. Setup: Connect power/Ethernet/coolant lines, configure pool (e.g., ViaBTC, F2Pool), monitor via Bitmain UI. Not suitable for home use in Romford due to high power (~5.5 kW!), hydro setup complexity, and need for dedicated space/ventilation. Variants like S19 Pro Hydro (170–184 TH/s) or newer S19 XP Hydro (255+ TH/s) offer better efficiency.

Profitability and Pricing

As of January 22, 2026 (BTC ~$90,000–$93,000 range, network difficulty ~146T), gross daily revenue ~$6–$7 USD (pool mining). At Romford UK rates (~0.25–0.30 GBP/kWh), daily electricity £32–£38 — resulting in net loss (£25–£30/day negative) without very cheap power (e.g., <$0.07/kWh for breakeven). It’s marginal or unprofitable at current high difficulty unless hosted in low-cost regions or with heat recovery.

Pricing (used/refurb common in 2026): $1,500–$2,000 USD ($9–$13/TH; e.g., CryptoMinerBros ~$1,999, resellers like ASL Miner ~$1,400–$1,500). New stock rarer/older batches; check Zeus Mining, BT-Miners, or eBay for availability. Cheaper than newer hydro models (e.g., S19 XP Hydro ~$1,600–$3,000+ for higher hashrate).

Compared to recent queries:

• Vs. MICROBT WhatsMiner M60 (air-cooled, ~172 TH/s): Similar hashrate but air vs. hydro (S19 Hydro quieter, needs cooling setup).
• Vs. Bitdeer SEALMINER A2 Hydro (500+ TH/s): Much lower hashrate/power but easier/cheaper entry for hydro.
• Vs. home options (Bitaxe, Canaan Nano): Industrial scale vs. hobby low-power.
