The Rinnai RUR160 is part of the Sensei SE+ Series, a line of super high efficiency, Energy Star Qualified, tankless hot water heaters. The RUR160 is for residential and commercial use. The RUR160 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 time of purchase. Indoor installation of the RUR160 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 exhaust to go out. Outdoor installation does not require venting. This item, the RUR160i, is for indoor installation and requires venting.
The Rinnai Sensei Series with condensing technology offers built-in freeze protection down to -22°F on the indoor units. The unit features an integrated check valve located between the turbo fan 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.
It features 160,000 BTUs and hot water delivery with a flow rate that ranges from 0.26 - 8.0 GPM. The minimum GPMs is perfect for low demand uses such as shaving, where warm water is needed but not at a high rate! It is the ideal tankless solution for a home with 2 - 3 bathrooms. The RUR160 is optimal for simultaneous use of 2 - 5 fixtures at one time. So 2 people can shower and get ready to go out, while someone else is washing the dishes, and still have hot water to run a load of laundry or the dishwasher or both! Simultaneous fixture use is directly linked to the ground water temperature. Please refer to the chart in the photos above. The MC-91-2US controller is included with the water heater as part of the front panel. The default minimum temperature setting is 98° with a maximum of 120°F. The unit offers a maximum setting of 140°F with parameter adjustment. A parameter adjustment on the RUR160 unit can be made for greater hot water flow - up to 9 GPM - as well.
In a condensing tankless water heater, such as the RUR160, once you turn on the tap, cold water goes into tankless heater and the flame is activated. Water is pre-heated as it passes through the stainless steel heat exchanger then continues to be heated as it passes through the coils in the copper heat exchanger, exits the water heater, into your pipes and up to the fixture calling for the hot water. Depending on the amount of hot water called for, the flame adjusts accordingly to heat more or less water.
Benefits of a Tankless Hot Water Heater:
- Endless hot water - Heats water as it goes through the pipes, offering endless hot water for your home (or business)
- Hot water on demand - Once you turn the water on, hot water runs through your pipes and out the faucet! Virtually no time or water is wasted waiting for the water to heat up
- Highly Efficient - Gallon for gallon, you will spend less money heating your hot water. With a tankless system the water is heated on demand rather than sitting in a storage tank. A storage tank typically heats the water intermittently throughout the day and night not only when it is needed. This unit is Energy Star Qualified and features an Energy Factor of 0.96 (the closer to 1.0 the better)
- Long lasting - Unlike a storage tank in which the water sits in the tank all the time creating sediment and rust, a tankless water heater will last longer
- EZ Connect - Allows for connection of two units together
The RUR160 offers WiFi Technology (Control-R WiFi Module, included) for remote monitoring, management. Remote diagnostics and monitoring requires a monitoring dealer. Rinnai service providers can monitor the efficiency of your tankless water heater with WiFi monitoring as well as send you automatic maintenance alerts and possibly offer faster service. The Control-R WiFi Module attaches right to your Rinnai tankless water heater. Simply download the mobile app and you can control your hot water from anywhere in the home, as well as activate recirculation (if installed). The Control-R also allows for pairability and voice activation with Amazon Alexa.
The RUR160 includes Rinnai's ThermaCirc 360 Recirculation Technology. Recirculation technology allows you to set patterns that coincide with your hot water usage. The Dedicated Mode works in conjunction with a dedicated return line and the integrated pump recirculates water from the RUR160 through the return line and back to the heater. If a dedicated return line is not available, installing a thermal bypass valve at the fixture furthest from the RUR160 is possible for use in the Crossover Mode. The RU160 ships with isolation valves for easier maintenance and service. A Thermal Bypass Valve is included with this unit for use with the crossover recirculation mode. The MC-195T-US is a controller for recirculation (sold separately) and is not compatible with the Control-R WiFi controller.
With a tankless hot water heater, space is rarely an issue. A Rinnai RUR160 tankless heater takes up a little more space than a carry-on suitcase - 26.4"h x 18.5"w x 11.4"d. They are designed to be installed on a wall with the following clearances:
(0" from vent components)
|Bottom / Ground:||12"|
(minimum of 24" required for servicing)
The RUR160i offers flexible venting options for installation.
- Concentric or Schedule 40 PVC/CPVC
- Direct vent (Concentric and Twin Pipe)
- Non-Direct Vent (Room Air)
- Common Direct Vent (Direct Vent and Room Air)
- Maximum Equivalent Vent Lengths:
- Twin Pipe Vent Sizes and Lengths: 2"/ 65 Ft. or 3"/ 150 Ft.
- Concentric Vent Sizes and Lengths: 2" x 4"/ 65 Ft. or 3"x 5" / 150 Ft.
*Indoor and Outdoor Installation are specific to the model chosen. RUR160iP and RUR160iN are for outdoor installation and do not require venting while RUR160eP and RUR160eN are designed for indoor installation and venting is required. Both installation types are available in either Liquid Propane (P) or Natural Gas (N). Certified for installation in Manufactured (Mobile) Homes.
