What is the definition of a "hot water recirculation system"?

A hot water recirculation system is defined as a system that keeps hot water readily available at fixtures. This technology is designed to minimize wait times for hot water at taps and appliances, improving convenience and reducing water waste. The recirculation system continuously circulates hot water through the plumbing system and back to the water heater. When a hot water tap is opened, hot water is immediately available, rather than waiting for water to run until it reaches the desired temperature.

This efficient setup ensures that hot water is always within reach, providing comfort and efficiency in residential or commercial settings. By maintaining hot water within the pipes, it prevents the need to run tap water for extended periods, thus preserving water resources and energy that would be used for heating additional cold water.
