The upcoming U.S. Department of Energy (DOE) regulations for pool pumps will change the industry more than any other issue in recent memory. All manufacturers—domestic and foreign—must comply with the regulations that go into effect on July 19, 2021. Products made before this date can be sold throughout the channel, and existing inventory does not need to be returned.  However, all pumps made after this date must meet the new DOE energy efficiency criteria. These requirements are based on a new metric named weighted energy factor (WEF). WEF is the first industry-wide efficiency metric and will naturally impact both international and Canadian markets as well. The new WEF rating will be physically labelled on most pumps imported into the market after July 19, 2021, which will allow users to easily compare energy efficiency to other models. As consumers are becoming more educated on performance and the total cost of ownership of a pump purchase, WEF is an easy way to evaluate and compare the energy efficiency of pool pumps and will cultivate a new standard for evaluating efficiency worldwide. DOE-compliant pumps provide the same installation and performance requirements needed to successfully operate pools and spas while delivering significant energy savings and noticeably quieter operation, too.
