    Should i upgrade to a VS?

    Current pump. Singe speed. 1.5hp. 3450rpm. 230//115. 8/16 amps, My meter says i,m pulling 1600watts or 1.6 kw, Sta-rite. PHK2RA6F-103L. Motor #168453

    Live in michigan, runs almost 6 months of the year. 35 bucks a month x 6 = 210 bucks a year.

    So if a VS can save me 50% for example, i would save 105 bucks a year, x 4 years. 440 bucks.


    I seen a VS motor. 1.65hp for 400 bucks free shipping. Would that bolt into my current impellar/houseing and give the same water pressure/movement when set at max? Of my current pump.

    I have a spa and pool heater, so when i turn either of these on, i would want maximum pressure/flow.

    I don't know. More here, How To Replace the Motor on Your Pool Pump - INYOPools.com


    I run my VS pump at 1100 rpm for skimming, filtering and making chlorine with the SWG and it uses 150 watts. Very efficient.

    Check for state/utility rebates. I was able to get 2/3 of my pump paid for by my state rebate and self installing. I needed to to the entire pump since the "motor only" was not an approved unit. My payback will likely be 1.5 to 2 years.

    Yes it would.

    But when doing a cost analysis of a VS, you need to include the cost of protecting the drive. You will need surge protection for the pump electronics ($100-$200).


    Another option would be to replace the current motor with a two speed. Low speed saves about 75% in energy cost.

    As to which way to go, you just need to run the numbers to see if it is worth it.

    On the motor itself does it say it's a "56Y" Frame Number ??

    If so this should be a bolt in replacement but I'd still run it by whatever seller you use - - > A.O. Smith 1.65 HP Variable Speed Pool Pump Motor Square Flange - ECM16SQU - INYOPools.com

    The vs pumps are most efficient at low speeds so if you plan on running it at high speed for the same amount of time then I would say you won't really save anything.this also holds true for the 2 speed pumps.I personally am saving about 60 percent on my daily kw usage but running 24hr a day.I have had my vs pump In for 2 swim seasons now and because I bought and put it in myself it has already pretty much paid for itself.

    Oh and the rpm of the motor and the pump size will determine how much water pressure you will have so if the motor will do at least the same rpms and it fits on your pump then you should be fine
