Rinnai is raising the bar in tankless heating technology with their SENSEI tankless water heaters. Rinnai's SENSEI series provides a better experience for both users and installers alike with simple installation, serviceability, efficient performance, and flexible venting options. The SENSEI's advanced condensing technology can easily adapt to colder climates with freeze protection down to -4 degrees fahrenheit for outdoor units. The RUR199iN shines above all SENSEI series models by offering an integrated recirculation pump alongside Rinnai's incredibly efficient condensing design. A corrosion-resistant heat exchanger, integrated check valve, and included safety devices allow for efficient water heating for years to come.



Continuous Water for Multiple Applications 
Rinnai tankless water heaters provide an endless supply of hot water that remains uninterrupted, even when you're the last one in line for the shower.

Energy Efficient Promise 
Tankless water heaters avoid the need to keep a large amount of reserve water heated at all times. This saves energy by only heating water when you need it, while an entirely electric ignition avoids the constantly wasted energy of a standing pilot light.

Circ-Logic Recirculation Technology 
Rinnai's Circ-Logic technology allows users to set recirculation patterns that work with their usage patterns. This means that hot water is always available when needed without having to circulate during times of inactivity.

Wi-Fi Compatible 
Every SENSEI water heater is Wi-Fi compatible for remote monitoring and management.

Enhanced Combustion Design 
The Rinnai SENSEI series water heaters feature a fiber mesh premix burner that provides an even flame distribution for optimal performance and efficiency.

Stainless Steel Heat Exchanger 
The included stainless steel heat exchanger features corrosion-resistant properties to ensure reliable and long-lasting operation, while its superior efficiency puts the SENSEI series at the top of its class.

Flexible Venting Options 
Perfect for both new installs and retrofits, the SENSEI features the most flexible venting in the industry. Whether your install requires concentric, direct, room air, or common venting, the SENSEI series can handle it all.

Simple Installation and Serviceability 
The SENSEI water heater features an adjustable mounting plate and a rotatable pressure relief valve to accommodate a variety of install applications. An easily accessible control panel and parameter adjustment allow for fast and simple servicing.

Circ-Logic Recirculation Technology

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, ThermaCirc360™ technology allows for the simple installation of a Thermal Bypass Valve (included with purchase) at the fixture farthest away from the water heater.
