Hot Water Recirculation Systems
How Hot Water Recirculation Systems Work
The hot water supply line in your home carries hot water from the water heater to the various sinks and baths throughout the house. In a home without recirculation, when you turn on a hot water faucet, all the water sitting in the supply lines has to pass through the pipes before hot water from the tank reaches the faucet. As a result, gallons of water are wasted while waiting for hot water to arrive.
By running a return line from the last tap on the hot water supply line back to the water heater and installing a small circulating pump, hot water is circulated in the supply line and is immediately available when you turn on your faucet. The direction of flow moves from the water heater through the hot water supply line, through the return line, through the recirculating pump, and then back to the water heater.

Innovative hot water recirculation systems deliver hot water to fixtures quickly without waiting for the water to get hot. Rather than relying on low water pressure common in most water lines, recirculating systems use a pump to rapidly move water from a water heater to the fixtures.
In this system, a recirculating pump rapidly pulls hot water from a water heater while simultaneously sending cooled-off water from the hot water lines back to the water heater to be reheated. In addition to having the convenience of hot water on-demand, the system conserves water and can save energy.
Hot water recirculation systems can be activated by the push of a button, or by a thermostat, timer or motion sensor. Systems that use a thermostat or timer automatically turn on the pump whenever water temperature drops below a set-point, or when the timer reaches a setting. These systems ensure that hot water is always available at the faucet without any waiting.
