Two-speed and variable-speed pumps are great ways to conserve energy and save on your electric bill.
National and state regulations require your new pool pump be a two-speed or variable-speed pump*. This applies to pumps being replaced with a new pump as well as new construction. These pumps deliver immediate savings on your electric bill that can range from 75% - 90%.
• Variable-speed pumps can be set to run at a lower speed but still obtain the same or better cleaning/sanitation by running for longer periods of time
• Lower speeds reduce energy use to 1/4 of what it was, despite the increased run time.
• Lower speed also means less noise from the pump.
• High speed is still available for occasional needs such as spa therapy jets, pool cleaners or water features.
Why is now the right time to address this portion of your home energy budget?
