SmartPlus-e is a high-efficiency domestic hot-water recirculation system from Taco Comfort Solutions. It’s ideal for application with a dedicated hot-water return line and tank-style water heater. It pairs a 006e3 ECM hot-water circulator with the intelligence of Taco’s SmartPlug Instant Hot Water Control in one easily installed package. The SmartPlug learns hot-water usage patterns and delivers hot water when it’s needed, reducing energy use and extending the life of the water heater. The hot-water circulator is designed to make installation and operation of domestic hot-water recirculation systems easier and more efficient. It has a dial to select from three performance curves to best match the application and a setting selection guide to make the choice simple. 401-942-8000; www.tacocomfortsolutions.com.
