How this is calculated
- ENERGY STAR lists the power this model draws but no yearly figure. We estimate the annual energy use ourselves, assuming 8 hours a day at its low-speed setting, every day of the year. Your use will differ, so treat the cost as a guide.
- Yearly cost = annual kWh × your rate. Monthly cost is the yearly cost divided by 12, a flat average. Five-year cost keeps the rate constant; prices will change.
- Statewide averages are not your utility’s tariff. Use your bill’s rate for a closer number.
- We do not estimate watts or hourly cost: the source data does not include them.

Frequently asked questions
How much electricity does the Pentair 011056 use?
ENERGY STAR lists the power this model draws but no yearly figure, so we estimate about 335.2 kWh per year, assuming 8 hours a day at its low-speed setting, every day of the year. Your use will differ with the pool size, how many hours a day the pump runs and the months your pool is open.
How much does it cost to run?
At statewide average residential prices, the listed annual use costs about $42.64 in Nevada and $158.15 in Hawaii (EIA, 2026-08). Your own utility rate may be different; enter it in the calculator.
How does the Pentair 011056 compare with similar models?
Among 42 ENERGY STAR certified in-ground (self-priming) pool filter pump models with a similar rated horsepower, it ranks 12th lowest in annual energy use. Its 335.2 kWh per year is 4% below the median of 348.5 kWh.
What does the weighted energy factor mean?
It is thousands of gallons of water moved per kWh across the pump's speeds, so a higher number means a lower running cost. This model is listed at 6.9 kgal/kWh.
