The Rinnai V65 is part of the HE Series, a non-condensing line of high efficiency tankless hot water heaters. The V65 is for residential use only. The V65 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. Outdoor installation does not require venting.  The V65e is for outdoor installation does not require venting. 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. 

It features 150,000 BTUs and hot water delivery with a flow rate that ranges from 0.26 - 6.5 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 a single bathroom. The V65 is optimized for simultaneous use of 2 - 3 fixtures at one time. So 2 people can shower and get ready to go out, while someone else is washing the dishes, 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 MC-91-2US controller is included with the water heater. The minimum temperature setting is 98° with a maximum of 160°F. The unit offers selectable maximum settings at 120°F or 140°F.

In a non-condensing tankless water heater, such as the V65, 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.

Compact design saves space

  • The V65 is designed to be able to be installed inconspicuously on any exterior wall or compact space, hiding your unit and freeing up valuable space in your home. Rinnai tankless water heaters are perfect for any home.

Energy-Efficient Promise

  • Tankless water heaters avoid the need to keep a large amount of reserve water heated at all times. This saves energy by only heating water when you need it, while an entirely electric ignition avoids the constantly wasted energy of a standing pilot light.

Continuous Water for Multiple Applications

  • Rinnai tankless water heaters provide an endless supply of hot water that remains uninterrupted, even when you're the last one in line for the shower.

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 .81
  • An excellent choice for smaller spaces. Fits in crawl spaces and attics without compromising output
  • Provides a reliable source of hot water to multiple fixtures simultaneously in any size home
  • CSA and AHRI Certified
  • Life of unit extended with enhanced scale detection technology which reduces the possibility of serious damage to the water heater
  • 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
  • Professional installation required

  • 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.
