Review: It’s a great product! I am really happy with ours! - We are a big family. 5 grown adults. The Hot Water Tank we had (A.O. Smith, 50 gallon) had come with the house. If I am not mistaken, it was from 2004. We knew it would need replacing at some point…we just prayed it wasn’t gonna die —but it did. During Tornado Season. We had a tornado tear through town, and yes, we had damage. We needed a new roof and a new fence. Two Deductibles, totaling $14K. We were not amused. 😒 However, now that it had failed, what do we do? Tankless Water Heaters have been around and it has had many iterations. Our son, did a deep dive on TWH, and he found two. Both Rinnai. Given the #of people living here who like to take long hot showers…and me, who likes to do laundry in the morning…the 11.1 gallon was an easy pick. Our son installed it. (It’s good to have a kid in the trades) He said he had to add a 90* PVC for ventilation, but the install was pretty straightforward. It is so quiet! Our son’s bedroom is right behind the back wall of the utility room and he never hears it. I hear it recirculating in our bathroom, which is easily 70’ from the TWH. The promptness of hot water flowing to our bathroom is amazing! I’m happy to say I am happy how well it works in the background. Once that 50 gal tank was removed, planning placement was obvious for us. It saved space to get the other monster (The Furnace) room to breathe. We paid $1770.00 — and I know a regular old water heater would have been cheaper to buy, but with all the bells and whistles this product has, I think we will get our money’s worth.
Review: Fantastic - It works as expected. The only issue is the rinnai central app. It does not work. The heater is fantastic. Non stop hot water for the whole house. It does make some noise que running, nothing major if it’s in the garage or outside. Definitely worth the money. They should make these standard across the board. It will not take that much space. As for durability they offer a great warranty when installing. Would do it it again 10/10

### ⭐⭐⭐⭐⭐ Worth the money - unlimited hot water and hassle free!
*by G***O on November 3, 2025*

Wonderful replacement for our electric water heater. Our electric water heater sprang a leak so we decided to spend the bucks and go tankless. We had a propane tank already. Installation was straight forward and doable as a DIY project if you know something about plumbing. This water heater is very economical to operate, is saving us money on electric, and it gives us unlimited hot water. More than enough to run a washing machine, dishwasher, and shower simultaneously! Wish I would have made these change sooner. Now planning to put the same model in a mountain home.
