The Rinnai RL94 is part of the HE+ Series, a non-condensing line of high efficiency tankless hot water heaters. The RL94 is for residential use but can also be used in commercial installations. The RL94 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 RL94 utilizes concentric 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 RL94e 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 199,000 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 RL94 is optimal for 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 MC-91-2US controller is included with the water heater as part of the front panel. 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 RL94, 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.

Indoor and Outdoor Installation is specific to the model chosen. RL94eN   and RL94eP are for outdoor installation and do not require venting while RL94iN and RL94iP are designed for indoor installation and venting are required. Certified for installation in Manufactured (Mobile) Homes.

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
• 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
