Taco introduces the HotLink system for domestic hot water recirculation. Designed for systems without dedicated hot water return lines, Taco’s Hot-Link system substantially reduces the time it takes to receive hot water and can save an average family of four up to 12,000 gal. of water a year. The system ensures instant hot water comfort to showers and faucets by maintaining hot water at each fixture while returning the cooled hot water back to the water heater through the cold water line. The Hot-Link circulator includes an analog timer that can be set to operate during peak usage hours or for continuous operation.
