Can your pump be wired to run on 220v as well as 110v? If so, consider going to the higher voltage. Your pump will run cooler and more efficiently.

Also two speed pumps are just a real joy. Once you have one you'll wonder why everyone doesn't have them (everyone with pools ).

But my 2-spd is a Hayward SuperPump and it has to be wired to run on 220v.

Still, even at a high speed it is not very hot.

Yeah, they are more expensive, but I cut a deal on it when I bought my pool, so it was far less costly.

Plus the quiet of low speed means sometimes I have to check the return or listen to the pump from 3' just to be sure it's running.
