    1 Hp Jandy pump

    Based on my pool size @13,000 gallons I was recommended a 1 hp jandy stealth pump.. My question is.. I heard that a variable or a 2 speed pump is recommended for cost savings. Is it necessary on such a small pump?

    Thanks

    It will save you money in electricity to go with a 2 speed, even a 1 HP pump can cost hundreds of dollars per year to operate depending you electricity cost, length of swim season, etc.

    On low speed it uses 1/4 the power to move 1/2 the amount of water as on high speed. So even doubling the runtime on low to move the same water would be a 50% power savings.

    Do you already have a pump you are replacing? Most 2-speeds are 230V, so it is a little more difficult to find the 2-speed pumps if you are only wired for a 115V motor.

    No not replacing, going to be building and want to make sure I have proper equipment in place. I guess even at the small hp still makes sense for a 2 speed for savings.

    Thank you!

    Even the jandy stealth 1hp 2-speed is pretty big for your pool unless you will have high volume water features. If you want to stick with jandy, the flopro 1 hp 2-speed may be a better fit.

    Post the list of your equipment and details and we can comment.

    What will the volume of the pool be? Make sure they do not undersize your cartridge filter as that too can be a pain.

    Blue Granite

    Make sure your Cartridge is at least 190 sqft for a 13k pool.

    K thanks, we are thinking blue granite also. Are you happy with color? Do you have a picture?

    It is a nice blue. We were looking to avoid any aqua/green.

    This is all I currently have available:

    Looks great from above! Ours is only going to be 5 ft deep. So i am hoping not going to look too grey.
