Variable-speed pump vs single-speed pump: Pays for itself in a year with energy savings

A variable-speed pump can dial down to 300 watts most of the day versus a single-speed pump that runs at 1,500+ watts constantly. You’ll save $300–$600 a year on electricity, and the lower speed is quieter with better filtration. The upfront cost is higher ($800–$1,200 vs $300), but rebates and savings recoup that in one to two years.
