The optional standby power panel is designed to provide backup power during utility power outages, which makes it the best choice for supplying power to the circulating pump in case of an emergency. The standby emergency boiler may not always be available or may not be connected to the necessary circuits for the circulating pump. The external emergency panel and public panel may not have the capacity or capability to supply power to the circulating pump.
