Can upgrading my pool pump to a Variable Speed (VS) pump save on my electricity bill?
Yes, installing a Variable Speed (VS) pump is a wise decision that promises substantial long-term savings on your electric bill. All VS pumps adhere to Department of Energy (DOE) compliance standards and operate much quieter than single or dual-speed pumps. Experience up to 90% energy savings, and consider our suggested VS pump, the Pentair 013075 IntelliPro3 3 HP VS Pump. Learn more about this product by clicking here.
