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 HotLinkPlus-e combines a 006e3 ECM hot-water circulator with the company’s Hot-Link Valve and SmartPlug Instant Hot Water Control in one easy-to-install package. The valve, installed at the building’s furthest water fixture, sends cooled water back to the water heater so hot-water lines remain hot. The entire package is compact, making it ideal for tight spaces. Multiple connection options are available. A temperature sensor is included. 401-942-8000; www.tacocomfortsolutions.com.
