The Rinnai RLX94iN is a Natural Gas, a tankless hot water heater that is part of the HE+ Series. It meets SCAQMD / California Standards for improved Ultra-Low NOx emissions (<20ppm). The HE+ Series is a non-condensing line of high efficiency tankless hot water heaters. The RLX94iN is for residential use but can also be used in commercial installations. The RLX94iN is available only for use with Natural Gas, for indoor installation. Indoor versus outdoor installation is not interchangeable and must be decided at the time of purchase. Indoor installation of the RLX94iN utilizes concentric venting. With concentric venting, one pipe allows for fresh outside air in, while the other allows for the exhaust to go out.

It features 192,000 BTUs and hot water delivery with a flow rate that ranges from 0.26 - 9.8 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 2-1/2 - 3 bathrooms. The RLX94iN is optimal for the simultaneous use of 3 - 5 fixtures at one time. So 2 people can shower and get ready to go out, while someone else is washing the dishes, plus a load of laundry and not fear running out of hot water. Simultaneous fixture use is directly linked to the groundwater temperature. Please refer to the chart in the photos above. The standard temperature range is 98° with a maximum of 120°F. The unit offers maximum settings at 140°F (185°F commercial with MCC-91-2 controller) with field adjusted switch settings.

In a non-condensing tankless water heater, such as the RLX94iN, once you turn on the tap, cold water goes into the tankless heater and the flame is activated. Water is 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.

The RLX94iN is for indoor installation and requires venting. It is only available for use with Natural Gas (N). Certified for installation in Manufactured (Mobile) Homes. Complies with South Coast Air Quality Management District 14 ng/J or 20 ppm NOx emission levels.

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


  • Energy Factor of .82 and Uniform Energy Factor of .80
  • Rinnai's proprietary Circ-Logic allows the user to pair the unit with an external pump to create scheduled recirculation to reduce the wait time for hot water during peak use times
  • Provides a reliable source of hot water to multiple fixtures simultaneously in any size home
  • Only uses energy when hot water is needed
  • Has a lock function for temperature settings. Prevents unwanted changes to settings
  • Complies with South Coast Air Quality Management District 14 ng/J or 20 ppm NOx emission levels
  • Compatible with Wi-Fi devices
  • Enhanced scale detection lessens the possibility of serious, long-term damage to the unit
  • Temperature lock function prevents accidental or unauthorized changes to water temperature
  • Leak detection shuts off water to the interior units to limit property damage

  • 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.
