Taco’s SmartPlug instant hot water control has been awarded recognition as 2017 AHR Expo Product of the Year. A hot water recirculating system can save a significant amount of water – up to 12,000 gallons per year. But continuously running circulators and improperly programmed timers can waste energy by operating the circulator and water heater at times when hot water isn’t needed.
SmartPlug upgrades a hot water recirculation system to a “smart” system by making any corded circulator up to 94% more energy-efficient by learning hot water usage patterns and delivering hot water when it’s needed. This increases hot water comfort, reduces energy use and helps to extend the life of the water heater. There’s no programming or use of timers or aquastats. Installers simply plug the SmartPlug into a 110 V outlet, then plug the circulator power cord into the SmartPlug. Using a sensor that mounts to the hot water supply pipe, the SmartPlug learns the daily hot water usage pattern in a business and adjusts the circulator run time to deliver hot water when needed.
