Antminer T19
Budget alternative to S19. Lower binned chips at 84 TH/s. Very affordable on secondary market.
Quick answer
The Antminer T19 is a Bitcoin miner rated about 84 TH/s at roughly 3,150 W (about 37.5 J/TH), built on the BM1398 ASIC. An industrial-class unit — loud and power-hungry, best suited to a dedicated mining space, not living areas.
DCENT_OS Compatible
DCENT_OS is custom firmware developed by D-Central Technologies specifically for home miners. It transforms this miner with whisper-quiet fan profiles, 120V North American outlet support, auto-tuning for maximum efficiency, heater mode integration, and a clean web dashboard for monitoring.
Miners running DCENT_OS score higher on our Home Mining Assessment because the firmware is purpose-built to make industrial hardware livable in residential spaces.
Learn More About DCENT_OS →Professional-Grade Miner
This miner draws 3,150W and produces 75 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).
However, this miner is compatible with DCENT_OS — D-Central's custom firmware that adds whisper-quiet fan profiles and 120V North American outlet support. With DCENT_OS installed, this industrial miner can be transformed for home use.
Heater-Class Miner
At 3,150W, this miner outputs approximately 10747.8 BTU/hr of heat — equivalent to a standard electric space heater. Every watt consumed by an ASIC miner is converted to heat with 100% efficiency, making it a space heater that also mines Bitcoin.
During heating season, miner heat can offset part of the heat a room would otherwise need from another electric heater. The economics depend on your electricity rate, room heat demand, BTC price, network difficulty, and noise constraints.

Home Mining Assessment
Budget alternative to S19. Lower binned chips at 84 TH/s. Very affordable on secondary market.
The Antminer T19 is a SHA-256 cryptocurrency miner manufactured by Bitmain. It delivers a hashrate of 84 TH/s with a power consumption of 3150W, achieving an efficiency of 37.5 J/TH.
Built on the BM1362 ASIC chip, uses air cooling, operates at 75 dB noise level, weighs 14.4 kg, measures 400x195x290.
With a home mining score of 8/100, this miner is best suited for dedicated mining spaces for residential use. It produces 10747.8 BTU/h of heat output, making it effective for supplemental space heating.
At 37.5 J/TH, the Antminer T19 sits in the previous-generation efficiency tier; it runs best where electricity is inexpensive, or as a dual-purpose heat source.
Its waste heat (around 10747.8 BTU/h) can be ducted into a room, turning money you would otherwise spend on heating into hashrate.
D-Central’s in-house technicians repair the Antminer T19. DCENT_OS (D-Central’s GPL-3.0 open-source Antminer firmware) is in active development for the Antminer T19 — it is closed beta on the S9 today, with this platform planned for a later stage; join the waitlist to be notified when an image is ready (waitlist only, never a pre-order).
