Profitability Comparison
Bitcoin Space Heater L3 Edition
Bitcoin Space Heater S9 Edition
Based on BTC price of $61,030 and current network difficulty as of Jun 6, 2026. Actual results vary.
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 S9 Edition 2380852% more hashrate (0.0 vs 12.0 TH/s)
- Bitcoin Space Heater L3 Edition 27% better power draw (800 vs 1,100 W)
- Bitcoin Space Heater S9 Edition 100% better efficiency (1,587,301.6 vs 91.7 J/TH)
- 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)
- Bitcoin Space Heater S9 Edition 2% more home mining score (58.0 vs 59.0)
Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Bitcoin Space Heater L3 Edition | Metric | Bitcoin Space Heater S9 Edition |
|---|---|---|
| $499 | Upfront cost (MSRP) | $499 |
| -$1.92 | Daily net profit | -$2.31 |
| -$1,200 | Net after 1 year | -$1,342 |
| -$1,901 | Net after 2 years | -$2,184 |
| -$2,601 | Net after 3 years | -$3,027 |
| Does not pay back at current rates (negative daily profit) | Payback period | Does not pay back at current rates (negative daily profit) |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.

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.
