I can’t say enough great things about this tankless water heater. We use it on our rv and have had zero issues. We’ve tried a few others and they didn’t last as long or held up as good as this one. It has awesome water temperature. We haven’t had any leaks, or any problems!

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.

Great water heater, easy install if you have plumbing and electrical knowledge. NOT plug n play nor does it have a plug in power cord. Must be wired to a switch.After install I got an error code 11 which is a problem with the propane. After some research I found that my regulator on my propane tank was 20 psi. Fortunately my regulator had a dial to adjust pressure down between 8 w.c and 13 w.c. and it fired up and works great. I'm replacing my adjustable regulator with a 2 stage 11 w.c regulator to avoid any future proplems. Hope this helps :)

We installed this on a shipping container Tiny Home. The pipe fittings were tight and well made. The installation confusion centers around the electrical connections. First, the rubber grommet where the power wires exits the unit obviously does not meet code fo an external application and the grey plastic fitting does not match any PVC thread size. Secondly, the wires themselves are only 20 gauge. These do not seem to meet any code out there however after much searching of the internet, it seems that even professional electricians just wire up to it. We connected 12 gauge wire with wire nuts inside the cabinet and called it a day. The electric connections are supposedly only used for the LED display and the spark that lights the flame so we assume that gauge internal wire is ok. As for the PVC connection, we saw varied approaches to try for a water tight connection and we came up with using a 1/2" Schedule 40 female threaded connector pvc glued into their plastic connector. This connects to Liquidtite connectors and from there using those connectors and pipe into the container. This is the best water tight installation we could come up with that meets code.Lastly, it functions perfectly and within 30 seconds the water is quite warm and within a minute quite hot. All in all a very good purchase and other than the electrical connection very easy to install.We would certainly recommend it to anyone considering a tankless heater.

This water heater replaced an inside tank. Not only did it allow me to free up space in the house, it works flawlessly. It's also very easy to flush when it's time. Highly recommend.

My unit did not work upon installation by a certified plumber. If you do not use a certified plumber for installation Rinnai will not even talk to you. You are on your own. It was coding a #19 which was said to be an unusual code. The plumber called Rinnai for assistance did some things got it working. The extra fussing cost $128 labor that I had to pay. 8 days later the unit stopped working. Called the same plumber. The service call and diagnostics was another $193 only to find out the unit is totally defective. Rinnai did send a replacement at no charge but I had to pay the installation charge at $384. Rinnai likes to have what is called a kit put on at installation. It is used to flush the heater as maintenance. This requires a pump vinegar bucket and hoses. You would need to purchase these things or have a plumber do it at a cost. This should be done at least 1 time each year. So the install price including the Kit and all other necessities was $656. Plus the extra labor charges for a grand total of $977. This does not include the price of the heater. This is my experience in Texas near Dallas. Nearly 2 thousand dollars for a water heater so far and the clock is still ticking.

Love the heater now that I turned it up to 140I probably shouldn’t have given 5 stars because there is little info on how to turn the heat up to 140 without a controller but you can you must change both menus to b
