The R50LSI is the most compact option in the lineup, providing up to 5.1 gallons per minute (GPM) of hot water at a 35°F rise in temperature. It is an ideal choice for smaller households or apartments where space is a premium. It operates using a direct vent system, ensuring safe exhaust of combustion gases outside the home. The R75SLI, with a maximum output of 7.5 GPM, is suited for needs such as multiple showers running simultaneously, making it perfect for medium-sized homes.

Moving on to the R94LSI and R98LSI, these models provide even greater capacity and efficiency. The R94LSI offers an impressive 9.4 GPM flow rate, while the R98LSI reaches a peak of 9.8 GPM, supporting larger family requirements and ensuring hot water availability for multiple applications concurrently. Both models incorporate Rinnai’s advanced Circ-Logic technology, which allows users to set schedules for recirculating hot water, minimizing wait time and enhancing convenience.

For commercial applications, the R98LSI-ASME is a specialized model that includes the American Society of Mechanical Engineers (ASME) certification. This makes it suitable for larger facilities, such as restaurants, schools, and other institutions that demand a robust and efficient solution for comprehensive hot water needs.

All these models feature a user-friendly digital controller, enabling easy temperature adjustments and real-time monitoring. Moreover, their compact design means they can be installed in various locations, saving valuable space. The Rinnai tankless water heaters utilize a highly efficient condensing technology, resulting in a lower carbon footprint and reduced energy costs.
