    Need Advice: 2HP Jandy or Variable Speed

    I have to decide do I take the standard package with the 2HP Jandy pump or pay an up-charge for the Variable Speed.

    Here are some specifics to consider:
    * Free Form Pool, ~33,000 gallons
    * Plumb for future waterfall
    * Plan on adding solar heating in 1-2 years

    From what I've heard, a variable speed saves money. However, I may need the 2HP for the waterfall & solar heating.

    I would appreciate experience and feedback to help me make the right decision.

    Welcome to TFP!!!

    Which VS pump? What is the upcharge? Do you get a rebate? How much is your electricity?
    The answer to these determine if the VS will eventually save you money.

    2HP is likely much too big anyways, depending on how big or a water feature your are considering.

    The greatly over-simplified rule of thumb is that electric rates of $0.20/kwh or higher justify a variable speed, while below that you should get a dual speed.

    Hi JBlizzle,

    Cartridge filter cl340
    Pump jandy 2 h.p power flow

    The Variable pump upcharge is $750. I believe I'm at $0.09/kwh right now.

    I think the waterfall is fine. I'm concerned about the solar heating on the roof because I read somewhere that you need the powerful pump to push the water up. I have a 2 story house.

    With electrical rates that low, the variable speed pump is not going to pay back the additional up front cost.

    Nearly any in-ground pump can handle solar panels that are up two stories.

    Thank you everyone! We'll probably post photos of our project as it gets going.
