Rinnai highlights its latest non-condensing tankless water heater: the RE Series, featuring Smart-Circ Intelligent Recirculation technology. Manufactured at the new U.S. Griffin plant, the RE model provides PROs and customers with the latest hot water technology to improve overall performance. With Smart-Circ, external controllers are no longer required, making the installation process an overall smoother experience. And the unit “learns” the users’ hot water patterns over a 7-day period and then will schedule the pump to recirculate patterns, accordingly, providing customers with immediate hot water.
