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. Indoor installation of the V65 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 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

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

 Features

• 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
