FFMiner DS19
Heater-Class Miner
At 980W, this miner outputs approximately 3344 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
The FFMiner DS19 is a Blake256r14 cryptocurrency miner manufactured by FFMiner. It delivers a hashrate of 3.1 TH/s with a power consumption of 980W, achieving an efficiency of 316.1 J/TH.
Measures 130 x 170 x 330mm.
With a home mining score of 31/100, this miner is best suited for dedicated mining spaces for residential use. It produces 3344 BTU/h of heat output, making it suitable for supplemental space heating.
At 316.1 J/TH, the FFMiner DS19 sits in the legacy efficiency tier, so it is most economical run as a space heater or for hobby and learning setups rather than for pure profit.
Its waste heat (around 3344 BTU/h) can be ducted into a room, turning money you would otherwise spend on heating into hashrate.
