Track the true energy footprint of daily cold plunges by combining your chillerโs wattage, runtime, and electricity rate. The calculator estimates daily, monthly, and annual costs so you can budget for recovery sessions or compare the chiller to traditional ice baths.

Cold plunging has exploded in popularity as athletes and wellness enthusiasts tout its recovery benefits. Electric chillers keep water near freezing without hauling ice, yet maintaining those temperatures draws a steady stream of power. Monitoring energy consumption helps you forecast utility bills and decide whether to schedule sessions daily or only on intense training days.
Chillers behave like compact air conditioners. Power in watts converts to kilowatts by dividing by 1000. Multiplying by runtime yields energy in kilowatt-hours:
Multiplying energy by the electricity rate returns cost :
The calculator expands daily values to monthly and annual totals so you can compare the chiller against other recovery tools.
| Chiller size | Approximate wattage |
|---|---|
| 1/4 HP | 500 W |
| 1/2 HP | 800 W |
| 3/4 HP | 1100 W |
| 1 HP | 1500 W |
Each calculation also produces best-, expected-, and high-use scenarios so you understand how runtime changes the bill during heavy training blocks.
| Scenario | Daily runtime | Monthly cost | Annual cost |

Insulate the tub, keep it covered, and position the unit in a shaded or climate-controlled space to reduce compressor runtime. Some athletes run the chiller only before sessions, allowing water to warm between uses. If your utility offers time-of-use pricing, schedule chilling during off-peak hours. Pair the data from this calculator with the home sauna operating cost calculator, compare hydrotherapy options with the hot tub heating time calculator, and explore alternative cooling with the aquarium chiller energy cost calculator.
Suppose a 1/2 HP chiller draws 800 watts for 1.5 hours each day at $0.18/kWh for 30 sessions a month. Daily energy equals 1.2 kWh, monthly consumption hits 36 kWh, and the monthly cost lands around $6.48. Annual expense totals roughly $77.76โuseful context when comparing subscription cryotherapy packages.
