Taco HLS-2 Hot-Link Recirculation System – Pump, Valve, Supply Lines

The Taco HLS-2 Hot-Link System is a domestic hot water recirculation solution designed to deliver instant hot water without the need for a dedicated return line. Using a circulator pump at the water heater and a thermal bypass valve under the sink furthest from the heater, it creates a recirculation loop through the cold water line, eliminating wasted water and reducing wait time. The system can save the average household up to 12,000 gallons of water annually.
