Hot-LinkPlus-e by Taco Comfort Solutions offers high-efficiency, intelligent domestic hot water recirculation ideal for retrofit applications. A dedicated return line is not required. The Hot-LinkPlus-e combines a 006e3 ECM hot water circulator with Taco’s Hot-Link Valve and Smart Plug Instant Hot Water Control in one easily-installed package. The Hot-Link Valve, installed at the building’s farthest water fixture, sends cooled water back to the water heater so hot water lines remain hot. The 006e3 circulator that comes in the Hot-LinkPlus-e package uses up to 85 percent less electricity than a conventional circulator. It has three performance curves to best match the application, and a setting selection guide to make the choice simple. The Smart Plug 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 entire package is compact, making it ideal for tight spaces. Multiple connection options are available. A temperature sensor is included.
