Enjoy an endless supply of hot water with the SENSEI™ RSC199iP Super High Efficiency Plus condensing tankless water heater from Rinnai. Only the size of a small suitcase, the propane gas RSC199iP model is compact, easy-to-install and perfect for indoor locations.
With Smart-Circ, installation just got easier. External controllers are no longer required to set-up recirculation for your customers. Smart-Circ “learns” users hot water patterns over a seven-day period, then schedules pump and tankless recirculation patterns accordingly. Users enjoy hot water during regular demand periods, while saving energy and money.

You’re all set! Hot water will be ready for you based on your previous usage schedule. As hot water events are added throughout the week, scheduled recirculation adjusts accordingly.

Rinnai Circ-Logic recirculation technology allows users to set recirculation patterns that coincide with their hot water usage patterns. Hot water is available when needed, without the expense of circulating it during times of inactivity. Two recirculation modes are available:
Dedicated Mode - With a dedicated return line, the integrated pump recirculates water from the tankless water heater through the return line and back to the heater.
Crossover Mode - In applications where a dedicated return line is not available or is difficult to install, Circ-Logic technology allows for the simple installation of a Thermal Bypass Valve (included with purchase) at the fixture farthest away from the water heater
