Taco Comfort Solutions SmartPlug is a hot-water recirculating system that can save homeowners a significant amount of water — up to 12,000 gal. per year, the company states. The SmartPlug upgrades a hot-water recirculation system to a “smart” system. This technology makes any corded circulator up to 94% more energy efficient, Taco notes, by learning hot-water usage patterns and delivering hot water only when needed. This increases hot-water comfort, reduces energy use and helps to extend the life of the water heater. There is no programming or use of timers or aquastats. Simply plug the unit into a 110V outlet and then plug the circulator power cord into the SmartPlug.
