The cost of operating a spa, including heating water and running pumps, is highly variable and depends on a number of factors, including these:
Because all these outside factors may come into play, it is very hard to determine a typical cost of use.
|Estimated annual consumption||Estimated annual heating cost|
|Above-ground spa (6 ft. x 4 ft. x 2.5 ft.)||7,167 kWh/year||$522.47/year*|
|Octagonal in-ground spa (8 ft. x 2.75 ft.)||2,583 kWh/year||$188.30/year*|
*Rate D average: 7.29¢/kWhData and assumptions used for estimate:
