Original unit was manufactured in 2006 and supposedly had a 10 year warranty on the heat exchanger and 5 years on the circuitry, electronics, and igniter. After the old unit began failing I called a Rinnai authorized serviceman who looked at the unit and originally told me the unit was improperly installed with out a condensation trap line. After a rather long phone call with Rinnai, he then reversed himself and said my unit was one of the units designed without a trap line and later units were redesigned with a condensation line. Note the small fitting coming out of the top of the RL94iN, this fitting was not on my old unit. So Rinnai admitted they designed a defective product, and later corrected. But my still valid warranty would not cover my old unit. I was told the warranty covers the heat exchanger for 10 years, and the circuit board and electronics for 5 years. I have included a picture to show the water damage (rust) as a result of the design defect. From my understanding the damaged part is the igniter and is not part of the heat exchanger according to Rinnai. Additionally, labor and any service charges are NOT covered by Rinnai on any of their water heaters, so I was out 70 dollars for the service call.
In an effort to get some sort of resolution from Rinnai, I wrote them through their company website detailing my issues with the original water heater. After a couple of weeks, they eventually responded with a generic "How a tankless water heater works" email that for all intents and purposes was cut and pasted from a sales brochure. Seriously?
Bottom line, don't expect any support from Rinnai if you decide to purchase one of these heaters. I had the distinct impression from my the Rinnai rep (to his credit he was professional and courteous) that Rinnai was going to do whatever was necessary to weasel out of any warranty coverage. If you do decide to purchase one of these units, be sure to account for the useless factory warranty from Rinnai.
2 Adjustable wrenches, Teflon tape, measuring tape, a whole lot of patience. And some experience with plumbing. And more tools.
And if you have to install a new gas line.. yeah good luck with that, you may need a plumber/ a whole lot of digging! and it will cost you a pretty penny, so I hope you saved up?
For me my water heater went out. My second water heater to go out. When this second one went out, the inner liner around the relief valve went bad. And so this pin hole leak grew.. and grew, and since I thought things were just fine.. well my utility room ended up getting pissed on by my old water heater. So I had heard of tankless water heaters and of Rinnai in particular, and its Japanese quality, and decided this time around I was going to try something different.
One of the big things you may forget about is the venting with this install, both the amount you need and the tools for the job.. One, depending on where you live and your buying this unit, you might get screwed vent wise. If your here on Amazon thinking about buying one, it means your probably slightly educated about new plumbing tech, and you don't have any local dealers.
The closest Rinnai dealers/service guys were like 50 miles away for me. So I decided to install this badgirl myself. Or try to. Or fail trying! I think failing while your running is the best.. because that momentum you build up before you fall face forward into failure.. thrilling and impactful!
Two mistakes I made when ordering this were:
1.I didn't think of a GREAT way to cut the venting material. (I was like I have a hacksaw, should be no problem, WRONG! it was tedious at best) you really need good solid clean cuts with the venting material, because of the airtight seals the gaskets form in the material.. Like if you don't have good clean cuts, the joining of the material will go from really annoying.. to use your imagination. )
Here's a solution! Also you can use this to cut drain pipe later on when you need to. Also it looks like there's a long lead up time to getting the actual product for some unknown reason so if your planning ahead, may want to just go ahead and bite the bullet. Why else do you have that prime account?
2.I ordered the outdoor vent termination kit right? well that's all well and good if I had an extremely short distance to go.. But I had a foot beyond that, and also needed some 45degree elbows. And vent extensions. Spoiler! (I could not buy the vent extensions locally! no one had any... so I end up ordering those off amazon as well!- - -but after I had my new tankless water heater and had installed it and so I had to cap my cold water supply line and take a cold a$$ bath because I couldn't vent my unit) FUN TIMES!
Anyways, my knee jerk reaction on this install. It's actually pretty straight forward. Rip out your old tank, plumb new lines in, make sure you got the correct adapters to hook up. make sure you don't reverse your lines, label stuff, take your time.. hook it all up and it throws a fault! So the little computer in this unit worked good. Correct that issue. And good to go!
It's quiet for the most part. 120 degrees Fahrenheit in the summer time is hot enough. I may tinker with this later. Depends. I did not install a recirculating set up, I just did a straight forward install, and so I do experience that "Sandwich effect" on the water, but I had that with my hot tank water heater, so its nothing new.
Works fairly quickly.
Also, this unit in particular came with the Rinnai Union/Drain Valves... I ended ordering a set of Union/Drain Valves .. so now I have extra, accidentally. Just a heads up.
If anything worth anything happens down the line. I'll give an update. Or if your reading this review five years down the line and want to know how this unit has held up, just send me a request. If I still live in the same house I'll try and reply. But not to technical questions.
Good luck if your doing a self install and not a plumber. I'm very grateful my unit function great right out of the box pretty much.
P.S. I wish plumbing were easier and more straightforward. Like plug and play. I have a feeling there's a whole industry here for future new housing if someone can make it happen.
Year Update + Change:
Well its paid for itself now. My gas bill has been continuously cheaper, even though I completely take advantage of the continuous hot water.
I'm really glad I bit the bullet & made this buy. I didn't know how it would work out at first, but as long as I don't overwhelm the unit, like washer filling with hot water , because washer is pulling a lot of hot water volume, while running hot water for the bath, its pretty freaking awesome!
Its honestly continues to work better than I could ever have hoped for & that's on a 1/2" instead of 3/3" line.
They now don't have a workbench to service it in a workshop. Called 3 other Rinnai dealers...Same issue. The best hey can offer is that I reinstall the unit myself, and call for service (paying the $200 travel fee). Right now I have a defective unit...With no support whatsoever from Rinnai.
This is a piece of crap, with lousy support.

After purchasing this I now save $45 a month on the rental cost. I hired a gasfitter to install it.
Quiet and efficient
