What’s Different About the S1B?
Cost to Run (Estimated)
| Scenario | Typical Draw | Assumed Use | Rate | Est. Cost | Notes |
|---|---|---|---|---|---|
| Cold plunge (no chiller, tap water + ice) | 0 kWh | 124 gal fill; partial ice top-off | Water/Sewer ≈ $0.01–$0.02/gal | $1.25–$2.50 water (+ ice if used) | Using tap water only is lowest cost; ice adds variable expense. |
| With compatible ¾ HP chiller (maintain 45–50°F) | ~450 W (duty-cycled) | Continuous maintain, covered | Electric $0.12/kWh | ~$12–$25 per month | Estimate assumes moderate climate and good cover; warmer sites cost more. |
| Hot fill (from electric water heater) | ~9–12 kWh per full hot fill* | Heat 124 gal from ~60°F → 100°F | $0.12/kWh | ~$1.10–$1.45 per full hot fill | Gas water heat is typically cheaper; partial top-offs reduce cost. |
*Engineering estimate; actual energy depends on inlet temperature, heater efficiency, and how hot you run the tub. Always keep covered to reduce heat loss.
