Rinnai RE180i High Efficiency Non-Condensing 8.5 GPM Tankless Hot Water Heater

It features 180,000 BTUs and hot water delivery with a flow rate that ranges from 0.13 - 8.5 GPM.  The minimum GPMs is ideal 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 two bathrooms.

The RE180i is optimal for simultaneous use of 3 - 4 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 ground water temperature. Please refer to the chart:

An integrated controller is included on the water heater.  The minimum temperature setting is 98° with a maximum of 140°F.  The unit provides maximum settings at 125°F with an option to increase to 140°F.

In a non-condensing tankless water heater, such as the RE180i, once you turn on the tap, cold water goes into 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.

• 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 features an Energy Factor of 0.82 (the closer to 1.0 the better)
• Ultra Low NOx - Complies with South Coast Air Quality Management District 14 ng/J or 20 ppm NOx Emission Levels
• 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
