    • It’s a great product! I am really happy with ours!
Style: RXP199iN - 11.1 GPM - With Pump
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. ... show more

    • Worth the money - unlimited hot water and hassle free!
Style: RXP199iN - 11.1 GPM - With Pump
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. ... show more

I bought this a number of months ago to replace an ailing Bosch FX240 that's about 20 years old. I finally got to a point of replacing the old one. I did have to run a 2 inch PVC to the side of the house for the exhaust and transitioned one of my old stacks into an fresh air intake. This Heater just works so much better and seems like I have more control over the water temperature now at the faucet. I'm very pleased with this unit. ... show more

    • Hot water fast!
Style: RXP160iN - 9 GPM - With Pump
I got this with the recirculating back through the cold line. That’s a great feature. Replaced a non condensing heater so had to replace all the exhaust pipes with plastic due to the corrosive exhaust. Easy install since everything else was right there. It remembers usage patterns pretty well, so there’s always hot water within 5 seconds for my morning shower. If you take a one off shower, you may have to wait. One downside of using the cold water for recycle is that it takes a bit to actually get cold water out of the faucet you do the cross over at. We did the bathroom so not the end of the world. My downgrade on rating is on the noise level. We have this in an attic and either the air blower or the recirculating pump has a deep hum that vibrated the whole wall down to our ground floor. I put some sound damping washers on the mounting bolts, which have made it bearable, but you can still hear it every once in a while. Oh! Almost forgot, if you set the recycle to always be ready, it will go on and off through the night, so keep that in mind. Honestly if we had a garage to put this in instead of the attic I’d give it 5 stars. ... show more

    • Fantastic Water Heater
Style: RXP160iN - 9 GPM - With Pump
Review Image by Carlos Parra Carlos Parra
High quality build and tech design. Installation is straight forward thanks to the excellent, detailed instruction manual*. Nonetheless, pre-planning mounting location, materials, electrical service outlet if not already available, is strongly advised. To really maximize energy efficiency, the On Demand BLE Bluetooth button accessory is recommended vs the auto cycle which I found to be cycling every 10mins vs. 28mins as defined by the temperature setting. It was to the point that even the cold water taps were warm, so a lot of wasted energy. Instead, we bought the BLE button accessory ($32) to activate the water recirculation 5 min cycle while getting ready to shower; we turn on shower and with 15 seconds, hot water is flowing saving lots of water and energy!! We are thrilled by knowing we will be saving tons of water and energy year over year. * My only critique is the installation manual is limited in explaining some of the non-critical setup parameter features when configuring the unit for initial operation and does not make clear what you need to set up the Bluetooth on demand operation. I had to call their tech support to figure out the cost effective BLE button option ($32) for on demand set up. Also the app is very limited for the customer personal use features unless you buy a wifi module accessory to allow some remote features set up (more complex installation, $200+). Overall minor quips. The unit is of high build quality and sophisticated technology design that provides hot water efficiently and saves water due to the On Demand recirc feature!! Love it! ... show more
