The Hot-Link System is designed for hot water recirculation and is ideally suited as a retrofit solution for homes without a dedicated return line, says the company. The system’s technology eliminates the wait for hot water and the wasting of thousands of gallons of water down the drain while waiting for hot water to arrive. The recirculator includes a composite bypass valve and a stainless steel circulator with a timer and line cord. The one-pump, one-valve combo is easily installed and does away with the need to run a dedicated return line back to the water heater. The timer on the pump enhances its energy efficiency during evening and mid-day downtime. The system begins working when the timer-activated pump, which can be conveniently installed at the water heater, pushes hot water toward a one-way Hot-Link bypass valve beneath the furthest fixture in the house. The valve acts as a sort of drawbridge between the hot and cold water supply lines. As long as the water in the hot line remains cold, the valve stays open, and the cold water is sent back to the water heater through the cold water line. But when incoming water reaches approximately 100°F, the Hot-Link valve closes. Hot water is delivered immediately when any tap is turned on in the house.
