Rinnai RL94EN Pros and Cons

The Pros

The Rinnai RL94EN is an Outdoor Natural Gas tankless water heater that is capable of producing up to 9.4 Gallons per Minute which is great for larger homes. This particular model by Rinnai will let you use as many as 5 different plumbing fixtures all simultaneously which is incredible.

The Cons

While the Rinnai RL94EN is great for large homes, it may be more than is necessary for smaller or even mid-sized homes. If you do not need a tankless water heater that produces 9.4 GPM then there are more inexpensive alternatives that I would recommend looking into.


I have researched and read through many other reviews and there is nothing but positive feedback on the Rinnai RL94EN. This tankless water heater is Energy Star Certified and is 83% Thermal Efficiency. I would definitely recommend the Rinnai RL94EN to anyone needing 9.4 GPM water output.

Where to buy the Rinnai RL94EN

You can purchase the Rinnai RL94EN at various hardware stores or places online. Typically on tankless water heaters you will find that Amazon has the lowest prices. I would definitely check there first before you buy and sometimes you will have the option to buy used as well.
