Recirculating hot water heater

Recirculating hot water heater

Systems that use a thermostat or timer to automatically turn on the pump whenever water temperature drops below a set-point, or when the timer reaches a specific setting. Hot-water recirculation systems can be activated by the push of a button or by a thermostat, timer, or motion sensor. Such systems ensure that hot water is always available without any waiting time. Hot-water recirculation systems generally consist of a pump, an integrated electronic controller, and a zone valve.
