Profitability Comparison
Bitcoin Space Heater S19 Edition
Bitcoin Space Heater S9 Edition
Based on BTC price of $78,227 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
D-Central's two flagship Space Heater editions compared. Both repurpose industrial mining hardware for residential heating, but with very different heat output and mining performance.
The S19 Edition produces significantly more heat (and BTC) but requires a 240V outlet and has higher operating costs. The S9 Edition runs on standard 120V, is quieter, and is more suitable for smaller spaces. Choose based on your heating needs and electrical infrastructure.

Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Bitcoin Space Heater S19 Edition | Metric | Bitcoin Space Heater S9 Edition |
|---|---|---|
| $1,299 | Upfront cost (MSRP) | $499 |
| -$2.88 | Daily net profit | -$2.21 |
| -$2,350 | Net after 1 year | -$1,305 |
| -$3,401 | Net after 2 years | -$2,111 |
| -$4,453 | Net after 3 years | -$2,917 |
| 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
Which Space Heater Edition should I choose for a bedroom?
The S9 Edition. Its lower power consumption (1400W on 120V) and quieter operation make it more suitable for smaller, inhabited spaces. The S19 Edition is better for larger rooms, basements, or workshops.
Do both Space Heater Editions require special electrical work?
The S9 Edition runs on a standard 120V/15A North American outlet. The S19 Edition requires a 240V circuit, which may need an electrician to install if you do not already have one available.
How much Bitcoin can each Space Heater Edition earn per month?
Revenue depends on current BTC price and network difficulty. Use the profitability comparison above with your local electricity rate for real-time estimates. The S19 Edition earns significantly more due to its higher hashrate.
