Verdict
Two very different miners repurposed for home heating: the tiny S9 versus the powerful S19-based Space Heater Edition. Which makes the better Bitcoin-powered heater?
The Space Heater S19 Edition produces far more heat and mines far more Bitcoin. But it requires 240V power and is significantly more expensive. The S9 is the budget entry into Bitcoin heating on a standard 120V outlet.
Spec Deltas
Here is every spec where the Bitmain Antminer S9 eight-bin OEM reference and Bitcoin Space Heater S19 Edition actually differ, with the gap quantified:
- Bitcoin Space Heater S19 Edition 700% more hashrate (10.0 vs 80.0 TH/s)
- Bitmain Antminer S9 eight-bin OEM reference 59% better power draw (980 vs 2,400 W)
- Bitcoin Space Heater S19 Edition 69% better efficiency (98.0 vs 30.0 J/TH)
- Bitcoin Space Heater S19 Edition 28% better noise (76.0 vs 55.0 dB)

Frequently Asked Questions
Which Space Heater can run on a normal outlet?
The S9 Edition runs on a standard North American 120V/15A outlet. The S19 Edition requires a 240V circuit, which may need professional installation.
How much more heat does the S19 Edition produce?
The S19-based edition produces roughly 2-3x more BTUs than the S9 Edition, owing to its higher wattage. It can heat a larger room or serve as the primary heat source for a medium-sized space.
