The new Rinnai system in a garage setting.
Smart-Circ “learns” users’ hot water patterns over seven days, then schedules pump and tankless recirculation patterns accordingly. Hot water usage must be greater than 20 seconds to be added to Smart-Circ’s memory, minimizing any unwanted recirculation.
In addition, the RSC model will have a more efficient multi-speed DC pump, providing improved performance with a higher flow rate, better head pressure and more flexible operation. Upgrades will also be seen in high-temperature climes with the revised low-flow activation logic.
