This thing ROCKS!
Style: Propane
Size: 5.3 GPM
TLDR: This is now my favorite appliance in our entire house. Just buy it. I bought this to replace an ecotemp tankless hot water heater that leaked within a year of purchase. I was hesitant to spend an extra ~$200 on this unit, but I can honestly say it was worth it for sure. Showers: Incredible. This changed the way all of our showers work for the better. It's so effective that I can now balance my shower more on the "cold side" of the dial as opposed to turning it all the way to "hot" with my last hot water heater. This means that I have full cold water pressure at the same time as full hot water. This leads to a very high pressure, very satisfyingly steamy shower. Efficiency: In my case, this water heater will pay for itself in propane savings over a year. It's THAT good. Seriously, this thing uses less than half of the amount of propane on my last unit. Heat: It gets HOT. I called up Rinnai service to ask how to change the temperature from whatever the standard is to 140 degrees F. Customer support picked up immediately and was very knowledgeable. They walked me through it in less than 5 minutes and now I have HOT water for my dishes and laundry. Power: I can wash my car with steaming hot (140 dgF) water @ 60 PSI easily. The unit never chokes or gets cold. I can run a dual-head shower while running the dishwasher. Control: You can run a trickle of hot water with this unit. My last unit would only kick on if you had the hot water turned at least to half strength. This one has very fine controls, operating flawlessly at around .5 GPM.

Nice unit, no issues, easy install, just buy it
Style: Propane
Size: 5.3 GPM
Buy it. We have a much bigger rannai on primary residence and it is 12 years old and I've never serviced/flushed it as advised. We (2 teenagers me and wife) have had zero issues and the gals take lots of long showers, shave or whatever. Bought this one for a weekend tiny house/Park model RV/trailer. Much smaller capacity than my primary residence unit but happy to see it was the same quality, basic physical size and function . Just hook up 120v to unit for the ignighter, plumb in your gas and water lines and fire it up. Runs shower, kitchen faucet and bath faucet all on full hot with 115 deg water with no issue. Only have 3 fixtures so not sure how many more it could handle. Factory preset to 115 deg but changeable with dip switches to hotter or cooler. Came very securely packed. I installed service valves but will likely never service it. If I can get 12 plus years out of it without paying it any attention I'm happy. Doesn't come with a temperature controller but in 12 years we've only touched the one on my other unit when we moved it to paint the wall. We keep it set to 115 or maybe 120 default to be safe for any kids. That's too hot to hold your hand under anyway so never had a need to adjust. We have this unit plumbed to standard 20lb/30LB propane cylinders and it doesn't mind. Gained a free closet by replacing our tank unit with this one mounted on the outside wall instead of the inside wall.

Have had this up and running for almost a year. Have had no problems, works great. It’s outside and the lowest temperature it has seen is about 5 degrees. Worked great the whole time. No water pressure issues, and it gets hot very fast. 10/10 recommend

Don’t waste your money!
Style: Propane
Size: 5.3 GPM
Just used for a few months and stop working , give error. The board have inside can rust so easily or get damaged , this unit sold as outdoor but I don’t recommend this unit outside at all. Rinnai customer service doesn’t do anything ,they recommend ,I have to hired a technician to get fix the water heater. they don’t do exchange or nothing to help the customer , they want you go throw Amazon to resolve the problem. If you want a disposable water heater this is one. Good look!!

Impressive for it's size.
Style: Propane
Size: 5.3 GPM
Bought this to replace a Rinnai R85 that lasted 20 years with zero maintenance. Hope this one last even a fraction as long. Easy so set up. Just needed to change the maximum temp from 120 to 140 degrees. ***One word of advise....before you go to all the trouble to install these, connect the power and make sure it fires up. I bought this same unit from the big orange store and it was DOA. They took it back without issue, but I wasted a lot of time mounting and connecting plumbing/electric to it only to have to remove it.
