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.
| Antminer S9 | Metric | Bitcoin Space Heater S9 Edition |
|---|---|---|
| — | Upfront cost (MSRP) | $499 |
| -$2.74 | Daily net profit | -$2.21 |
| -$999 | Net after 1 year | -$1,305 |
| -$1,997 | Net after 2 years | -$2,111 |
| -$2,996 | Net after 3 years | -$2,917 |
| — | 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 I convert my own S9 into a Space Heater?
Yes. D-Central also provides consultation and parts for DIY conversions. However, the professionally tuned edition ensures optimal noise levels and thermal management.
Is the mining performance the same?
The Space Heater Edition may be slightly underclocked for noise reduction, which marginally reduces hashrate. The trade-off is a dramatically quieter machine suitable for living spaces.
