Antminer S19
Standard industrial miner, common in hosting facilities
Quick answer
The Antminer S19 is a Bitcoin miner rated about 95 TH/s at roughly 3,250 W (about 34.21 J/TH), built on 228× BM1398. An industrial-class unit — loud and power-hungry, best suited to a dedicated mining space, not living areas.
Professional-Grade Miner
This miner draws 3,250W 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).
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.
Heater-Class Miner
At 3,250W, this miner outputs approximately 11089 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.

| Period | Revenue | Electricity Cost | Profit |
|---|---|---|---|
| Daily | $3.70 | $5.46 | $-1.76 |
| Weekly | $25.88 | $38.22 | $-12.34 |
| Monthly | $110.91 | $163.80 | $-52.89 |
| Yearly | $1,349.38 | $1,992.90 | $-643.52 |
Heating offset estimates the value of heat replacing an electric space heater during heating season (~6 months/year in Canada). Actual savings depend on your heating setup and climate.

Home Mining Assessment
Standard industrial miner, common in hosting facilities
The Antminer S19 is a SHA-256 cryptocurrency miner manufactured by Bitmain. It delivers a hashrate of 95 TH/s with a power consumption of 3250W, achieving an efficiency of 34.21 J/TH.
Built on the BM1398 ASIC chip (76 chips per hashboard, 228 per unit), 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 11089 BTU/h of heat output, making it effective for supplemental space heating.
At 34.21 J/TH, the Antminer S19 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 11089 BTU/h) can be ducted into a room, turning money you would otherwise spend on heating into hashrate.
