Rinnai RSC160iN 9 GPM Condensing Tankless Water Heater

The Rinnai SENSEI® RSC160iN is a super-high-efficiency condensing tankless water heater designed to provide continuous, on-demand hot water with the added convenience of built-in recirculation. With a modulating heating range of 15,000 to 160,000 BTU/h and a maximum rated flow of up to 9.0 GPM, it delivers dependable performance for appropriately sized residential hot-water applications.

Unlike a conventional storage tank that continuously maintains a supply of heated water, the RSC160iN heats water when it is required. Its condensing technology captures additional heat from combustion gases, helping the system achieve a 0.95 Uniform Energy Factor while reducing standby energy loss.

A built-in multi-speed recirculation pump helps reduce the wait for hot water at frequently used fixtures. Rinnai Smart-Circ™ Intelligent Recirculation learns household hot-water usage patterns over time and schedules recirculation around regular demand periods. This helps improve convenience while avoiding unnecessary continuous pump operation.

The recirculation system can be configured with a dedicated return line or a compatible thermal bypass arrangement, depending on the home’s plumbing design and applicable local requirements. Professional assessment is necessary to determine the correct recirculation configuration for the property.

The compact wall-mounted cabinet measures approximately 31.3 inches high, 18.5 inches wide and 11.4 inches deep. Designed for indoor natural-gas installation, it saves valuable floor space and can fit into many utility rooms, basements and finished mechanical areas.

The RSC160iN is ENERGY STAR® certified, Wi-Fi capable and approved for Ultra-Low NOx operation. Wi-Fi functionality requires compatible Rinnai controls or accessories. Its digital controls and intelligent recirculation features provide a practical combination of hot-water performance, efficiency and everyday convenience.
