Rinnai R75LSE Pros and Cons

The Pros

The Rinnai R75LSE is an Outdoor Natural Gas tankless water heater that is capable of producing up to 7.5 Gallons per Minute which is great for mid-sized homes. This particular model is is Energy Star Certified and is also certified for manufactured homes.

The Cons

While the Rinnai R75LSE is great for small or mid-sized homes, it is not ideal for larger homes. If you have a larger home or a high need of continuous hot water flow then I would recommend going with a slightly larger tankless water heater than the Rinnai R75LSE.


Any reviews and feedback I have gathered for the Rinnai R75LSE have been extremely positive. People like how simple this unit is to install and of course also like the price. I would recommend the Rinnai R75LSE to anyone with a small to mid-sized home.
