    Pump Upgrade

    I just bought a house with a 25K gallon in ground pool. I am interested in upgrading to a variable speed pump but am unsure what would be compatible. I do like the reviews I have read on the Hayward EcoStar but I am not sure if it would be a direct replacement.

    Currently the pool as a M Centurion for Pac Fab
    3/4HP
    1.67SF
    RPM 3450
    HZ 60
    Volts 208-230/115

    I believe the filter is sand. PackFab SuperFlow PF-50.

    Thank you

    Welcome to TFP!

    The first thing to check is to make sure you have the correct voltage and enough amps available to run a variable speed pump. Your current pump can be wired for either 120 volts or 240 volts. The variable speeds all require 240 volts. The variable speed will also draw a noticeably higher peak current. Check what kind and amp rating is on the pump circuit breaker. 240 volt circuit breakers have two levers connected by a bar, while 120 volt breakers have a single lever. A variable speed will tend to require 240 volts at 30 amps.

    A variable speed pump will also be physically larger than your current pump. Most of the time this is not an issue, but if your pump is right next to something it could be an issue.

    Variable speed pumps are only really worth it in money saved terms if your current electric rates are $0.20/kwh or higher. If your electric rates are below that, you should look into the possibility of getting a two speed pump, or just replacing the motor on your current pump with a two speed motor.

    Re: Pump Upgrade

    I am going to upgrade the main electrical box and I would make sure there is enough power to run a new pump. We move a month from today so I will have to check what the current breaker is for the existing pool pump. I will have to check the clearance since it is next to a garage. I saw a picture of a Jandy Variable pump and it looks huge compaired to a Pentair.

    Given your low electric cost a 2-speed probably makes more sense if you do not have any special water flow demands.

    Nothing like a waterfall or anything cool like that. Thanks for the input. If you recommend a 2 speed then I will start researching those pumps.

    It's been a childhood dream to have an in-ground pool.

    Re: Pump Upgrade

    Still need to confirm whether you are set up for 120 or 240. Also, what are your suction and return pipe diameters? Pentair whisperflo and superflo are nice.

    Re: Pump Upgrade

    I was told the electrical box was only 60 AMPs so I need to have it upgraded when we move in next month. I need to get over there and check the diameters of the pipes.

    Currently there is a 3/4 hp but when I run the Hayward Energy Calculator they use a 2hp. Should upgrade to a 2HP if I do have a 25K gallon?

    Re: Pump Upgrade

    The house is 60 amps or your pool pad box is 60 amps? My pool pad is currently 20 amps.

    The pump size depends on you pool setup. If it is just a basic pool with no spa or water features then a 3/4 or 1 HP 2 speed should be plenty.

    Edit: I saw most of my questions were previously answered. I think 2 HP is way too big for the basic setup.
