With an enhanced combustion design, the Rinnai SENSEI Tankless Water Heater provides a better experience for both users and installers. Like all Rinnai Tankless Water Heaters, it's also vertically integrated. That means all key components are manufactured by Rinnai — to ensure Rinnai quality.
Condensing Technology for Colder Climates
The Rinnai SENSEI offers freeze protection down to -4o F (for outdoor units) or -22o F (for indoor units) through:
- NEW integrated check valve that prevents backflow from outside cold air
- NEW Fiber Mesh Premix Burner
- Integrated logic to temporarily activate the unit in extreme cold climates
Most Flexible Venting in the Industry
The Rinnai® Sensei™ can go in an old condensing vent system for replacement if needed, but new installs can use smaller, lighter, less expensive concentric venting.
