Rinnai CU199eN Commercial 199K BTU Outdoor Natural Gas Tankless Heater

More hot water, faster with the Rinnai Sensei series

The Rinnai Sensei series features an enhanced combustion design, to provide a better experience for both users and installers. All key components are manufactured by Rinnai to ensure well-known Rinnai quality.

New condensing technology for colder climates

You get freeze protection down to -4°F for outdoor units or -22°F for indoor units. The Sensei series achieves this by using:
• a new integrated check valve that prevents backflow from outside cold air
• a new fiber mesh premix burner
• programming that temporarily activates the unit during extremely cold weather

Stainless Steel Primary Heat Exchanger

Early in the combustion process, all high efficiency condensing tankless water heaters produce condensate. Rinnai's new R-evolution Primary Stainless Steel Heat Exchanger resists corrosion for better performance in the long run.

Another leading innovation: Venting

The Sensei series offers the most flexible venting options of any tankless. It can use the old condensing vent system when installed as a replacement tankless. Or, new installations can use smaller, lighter, less expensive concentric venting. Approved materials: PP, PVC, CPVC.

The 2" adaptor ring and cap allow for use of 3"x 5" concentric venting or 2" twin pipe venting.
• 14 possible vent configurations
• 9 compatible vent manufacturers

For use with natural gas or propane

Quick and easy conversion to/from NG and LP in just three simple steps. Kit is optional.

Frequently Asked Questions ("FAQ")

Q1: What is the difference between the RU, RUR and RUC series?
A1: Rinnai's RU series heaters such as the RU80e and RU90e are simply the outdoor versions of the RUC units.
The RUR series heaters such as the RUR98i and the RUR98e have a built-in recirculation pump. The RUC series heaters such as the RUC98i and the RUC80i do not have the recirc pump.

All of these heaters are condensing.
