Profitability Comparison
Bitcoin (SHA-256) profitability math does not apply here: the Bitcoin Space Heater L3 Edition mines Scrypt and the Bitcoin Space Heater S9 Edition mines SHA-256. Daily revenue for each depends on its own coin's network difficulty, block reward, and price — not on Bitcoin difficulty — so a single BTC calculation cannot compare them.
Verdict
Two budget-friendly Space Heater editions based on different algorithms. The S9 Edition mines Bitcoin (SHA-256) while the L3 Edition mines Litecoin (Scrypt).
The S9 Edition is the Bitcoin purist choice, mining BTC directly. The L3 Edition mines Litecoin/Dogecoin, which can be auto-converted to BTC. Both produce similar heat output. Choose based on your preferred mining algorithm.
Spec Deltas
The Bitcoin Space Heater L3 Edition and Bitcoin Space Heater S9 Edition diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Bitcoin Space Heater L3 Edition 27% better power draw (800 vs 1,100 W)
- Bitcoin Space Heater S9 Edition 20% better weight (10.0 vs 8.0 kg)
- Bitcoin Space Heater S9 Edition 38% more heat output (2,730 vs 3,753 BTU/hr)

Frequently Asked Questions
Can the L3 Edition mine Bitcoin?
The L3 is a Scrypt miner and cannot mine Bitcoin directly. It mines Litecoin and Dogecoin, which can be exchanged for Bitcoin through various services.
Which produces more heat?
Heat output is similar between the two as both operate at comparable wattage levels. The difference is in what cryptocurrency is being mined.
