Wyoming has about 3,000 residential pools, one for every 194 residents. Here is what running one costs at Wyoming's electricity price, and the calculators to keep yours clear.
Electricity in Wyoming averages 14.43 cents per kWh, below the median state's 16.32 cents. For a typical 20,000-gallon pool turned over in 8 hours a day:
| Pump | Per month | Per year, if run year-round |
|---|---|---|
| Single-speed, 1.7 kW, 8 h a day | $59.66 | $716 |
| Variable-speed at half speed, 16 h a day | $14.91 | $179 |
Switching saves about $44.74 a month in Wyoming. Run your own pump and pool size in the pool pump calculator, already set to Wyoming's price.
A covered spa whose 4 kW heater runs about 2 hours a day, with a 300 W pump on for 12 hours, uses about 353 kWh a month: $50.89 a month at Wyoming prices.
Heater time is the big variable: a cold winter or a waterlogged cover can double it. Enter your own numbers in the hot tub electricity cost calculator.
Wherever you swim, clear water comes down to a few numbers: free chlorine at 7.5% of your stabilizer or more, pH between 7.2 and 7.8, and enough pump time to filter all the water every day. Sunny, hot weeks use chlorine fastest, so test more often then.
About 3,000 residential pools, one for every 194 residents. That ranks Wyoming 50th of 50 states for the number of pools and 50th for pools per person.
At Wyoming's average residential electricity price of 14.43 cents per kWh, a 1.7 kW single-speed pump running 8 hours a day costs about $59.66 a month. A variable-speed pump moving the same water at half speed costs about $14.91.
About $50.89 a month for a spa whose 4 kW heater runs 2 hours a day and whose 300 W pump runs 12 hours, at 14.43 cents per kWh. Your heater time depends on weather and your cover.
