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 the 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 the exhaust to go out. Outdoor installation does not require 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 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.

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 groundwater temperature. Please refer to the chart in the photos above. The MC-91-2US controller 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.

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) for remote monitoring, management. Remote diagnostics and monitoring require 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 repairability 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

  • Researched and ordered my fireplace from US FIreplace Store. Pricing was a fair value however, the customer service was EXCELLENT! I had an issue with the direct vent venting. I called US Fireplace and the correct items were sent out the next day AND Janessa stayed on top of my return authorization and sent me the permissions and documents I needed to return the incorrect item and no cost to me, including return shipping. Overall, I am a very satisfied customer and my fireplace looks and operates flawlessly. I am glad that I selected US FIreplace to source my direct vent fireplace. Thank you for the great service.

  • I had placed an order, through Lowe's Home Improvement, for an Electric Firebox: Revillusion RBF42. Ordered 1st part of January. Was told I would have it in 3 weeks. When checking to see is it came in, was told it was delayed to 3/15. Was then told is was delayed until 4/25. Waited until 4/27 to check on it. Was then told it was now delayed until August. This firebox was going in a new Sun Room addition. I could not get my final inspection until the Firebox was installed. I went on line and googled for this same product. US Fireplace Store web site was given to me. This was on a Saturday. I call and reached a very nice man. Explain what I was look for. He checked and told me they had 30 of them in stock. I almost fell out of my chair. I clarified with him the product I was wanting. I ask how soon could I get it. He told me it would ship today. Again, was amazed. It arrived on the following Monday. What a pleasure and a relief working with US Fireplace Store and their employees. Exceed my expectations.

  • Great prices, quick delivery and fast hassle free services on the issue I encountered. I had purchased an electric fireplace unit that would not fit into the existing fireplace space. With one email I was able to get the wrong fireplace refunded and picked up at my home at no extra cost and the new one I purchased and delivered free of charge. Great company.
