  Hot Water Recirculation - How It Works

A return line is installed near the faucet farthest from the water heater. The return line is connected to the UP 15 series pump and flows back to the water heater. As water slowly cools in the hot water line, the UP 15 series recirculation pump then moves the hot water from the heater throughout the pipe back to the heater, creating a continuous loop of slow-moving warm water. When a faucet is turned on, warm water is instantly available for use with no waste.
