Rinnai updates condensing tankless water heaters

SENSEI RSC condensing tankless water heaters by Rinnai will replace further production of its RUR models, delivering Smart-Circ Intelligent Recirculation technology and easier installation, according to the company. With Smart-Circ, external controllers are no longer required to provide recirculation for customers, making installation a smoother process. 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 unwanted recirculation. In addition, the RSC model has a more efficient multi-speed DC pump, providing improved performance with a higher flow rate, better head pressure and more flexible operation.
