## Customer Reviews

### ⭐⭐⭐⭐⭐ Rinnai for the win
*by  on Reviewed in the United States May 10, 2026*

My 11 year Rinnai water heater died, so I had to purchase a new one. This one has been a fantastic replacement! My plumber was able to quickly install it in just a couple of hours and was able to adjust it to propane vs. natural gas within the heater.The price I paid for it here was cheaper than what I would have paid through my local Rinnai dealership.It has worked well, and has been easy to adjust the temp, if needed. It is nice to have hot water again.I would definitely recommend the Rinnai brand, if you are seeking a tankless water heater.

### ⭐⭐⭐⭐⭐ Professional installation is recommended.
*by  on Reviewed in the United States August 9, 2026*

This thing works great. High quality.

### ⭐⭐⭐⭐⭐ Saves money over regular water heaters
*by  on Reviewed in the United States June 22, 2026*

Its been a year now so I can honestly say this water heater was worth every penny I paid for it. It works very well, provides more than enough hot water and saves me a bunch of money over my previous hot water heater.
