    Filter operating cost?

    How much do you figure you spend on electric to run your pump per day / month? Do you run your pump day or night? Also
    how many hours a day do you run the pump?
    My pool is a 10,500 gallon (420 Sq Ft ) kidney shape. STA-RITE HRPB30, Sand filter 30" 98 GPM, 1 HP Maxi-Glas 2 pump, BBB Method, Taylor K-2005 test kit, 50 Watt 12V low-voltage pond light illuminates the pool at night for a nice soft glow.

    For me ..... $1.10 a day. cost 13 cents a KW. I run my pump 24/7.
    I run it around 350 watt per hour or less pumping 31 gpm.

    I also run my Rola-Chem chlorinator 24/7.

    Amps X voltage divided by 1000. That sum X your cost per kilowatt hour. That sum is the cost, in dollars and cents, to run your pump per hour. Multiply that sum X the number of hours you run your pump. This is the daily cost. Daily cost X 30 will compute your monthly cost.


    11 amps X 110v = 1210/1000 = 1.21 X .13 per kilowatt hour = $0.15 to run the pump for one hour X 8 hours = $1.20 is the cost to run the pump for 8 hours.

    $1.20 X 30 approx days in a month = $36 is the cost to run the pump per month.

    Wow - my kwh price is .11272. So 15 X 115/1000 = 1.725*.11272 = .19 per hour * 24 hours = 4.7 per day. I run 24 hours a day, for $139 per month. Without the formula, I'd have taken a guess that the pump costs around $150 per month. I didn't realize how variable electric rates are in different regions.
