A hot water recirculation system rapidly delivers hot water from a water heater to fixtures using a dedicated loop or an integrated loop. The plumbing system doesn't need to wait for water to warm up before moving it to fixtures.
A timer or a thermostat typically activates a hot water recirculation system. The system instantly turns on the pump once the timer reaches a specific setting or when the water temperature falls below a particular set point. Saving time, conserving water and reducing municipal energy waste are the main benefits of using a hot water recirculation system. The downsides include the possibility of very high energy consumption if the system pumps continuously and significant heat loss if the hot water pipes are improperly insulated.
