The Rinnai RU160e 8.0 GPM Sensei+ Condensing Tankless Hot Water Heater is part of the Sensei SE+ Series, a line of super-high efficiency, Energy Star Qualified, tankless hot water heaters. TheĀ RU160 is for residential and commercial use. TheĀ RU160 is available in either Natural Gas or Liquid Propane and must be purchased for indoor or outdoor use*.
Indoor versus outdoor installation is not interchangeable and must be decided at the time of purchase.Ā Indoor installation of theĀ RU160 offers both concentric and PVC/CPVC venting. The dual venting option on the top of the unit allows for maximum installation flexibility - one concentric vent or two PVC/CPVC/PP pipes can be used for venting. With concentric venting, one pipe allows for fresh outside air in, while the other allows for the exhaust to go out. Outdoor installation does not require venting.Ā This item, the RU160e, is for outdoor installation and does not require venting.Ā
Because of extreme temperatures and exposed water lines, outdoor/exterior installation is not recommended in locations from Virginia and north. Also, keep this in mind in mountainous regions of the country where extreme temperatures may also exist.
The Rinnai Sensei Series with condensing technology offers built-in freeze protection down to -22Ā°F on indoor units. The unit features an integrated check valve located between the turbofan and the combustion chamber to prevent cold air from entering the venting system and backflow of exhaust in common vent applications. The Fiber Mesh Premix Burner helps to provide even flame distribution for optimal performance for any demand.
