What Arizona homes use
EIA's 2020 residential survey found 376 kWh a year across 40 sampled homes that run one, 22% under the national 484 kWh. The middle half spans 133 kWh to 651 kWh, so a hot tub pump varies by 518 kWh between one household and another.
The circulation pump and jets, separately from the water heater. That average covers homes with a hot tub — 7% of homes here.
That makes a hot tub pump about 3% of the electricity an Arizona home uses. The remaining 13,227 kWh is what a hot tub pump is billed on top of, and on a tiered or time-of-use plan that is what sets the rate it meets.
