    Underperforming unit by posted specsWe had replaced our tank water heater twice already, and both times it was after a river was running through our garage out into the street. Got tired of that nonsense and decided to go tankless. Had already spent a great deal of time researching them thinking about upgrading when the time came. This unit appeared to have the ability to run our household easily based on provided specs. The truth of the matter is a little different. First off, yes it does come with a 120 max setting but you can circumvent this very easily by flipping a couple rocker switches (I think it was both number 6 switches, but you can find it in the manual) I turned ours up to 130. We have a 2000 sq ft house with two and a half bathrooms. We wash our clothes in cold water so that wasn’t an issue. Unit was installed and seemed to work well for a week. Then one day in the middle of a hot shower it went cold. ICE cold. Out of the shower into a towel and to the garage. Code 12, which returns as a flameout. Thought it to be a bit odd however a reset later the hot water returned as normal. I tried to see what the capacity of the unit was since it shows a 4 shower head capacity (not sure if that is showers or individual water sources) Either way, it can BARELY service two showers are the same time. Over the first few months, we have experienced multiple code 12 flame outs. The oddest part of this is that if my kids turn on their shower it will flame out and never get hot. I can reset the unit 100 times, and it will fail code 12 100 times. But I can reset the unit and send them to my shower and it will work without issue. I haven’t even bothered calling Rinnai because that shouldn’t be possible and I’m sure they’d blame something in the house or the installation or some other irrelevant nonsense as it shouldn’t be able to happen as it happens. Had the reviews shown this lower than spec output, I would have gotten a larger unit. However it would seem only those really happy with it had posted reviews prior to my purchase. After the date of my purchase I see a few other reviewers who had the same experience with underperformance. The next time I purchase one, I’ll likely pick a different brand.

    Decent but under deliversWe had our plumber install it about a month ago and wanted to get time to get used to it. We are a family of four and our current house is about 2000 sqft with two bathrooms, laundry, and dishwasher. So the good about it is it is a sleek design. Digital display is great. When it does heat up water it’s relatively quiet. When using a faucet continuously it seems to keep up with the water flow. Now for the bad. It advertises that can keep up to 4 faucets supplied with hot water, but when I put it to the test the most I got was three. Once I turned out a 4th faucet there was a steep drop off in temperature and then eventually it was nothing but cool water. I’m sure there’s very few times I would have four faucets running at the same time. But for households that want to do laundry and also run your dishwasher I’d be concerned. Normally there’s a lot of condensation in our washer so we know the water is hot but we did notice that that was not always the case. So we’ve had to learn to adapt to what we run and when. Personally I like my water a bit on the hotter side, this machine tops out at 120 which may be fine for most but if you’re like me then you may want to look elsewhere. If you’re living in a smaller space with a smaller household this may work, but I think somewhere down the line I will have to replace this with something that will better fit our lifestyle.

    Rinnai water heaterHad a Rinnai water heater for 20 years and the heat exchange box sprung a leak. I figure 20 years is good so bought another one. I’ve always loved the fact that you can control the max temp up to 140 degrees. This is a natural gas heater…on demand so the cost to run it is very low. You never run out of hot water.

  4. Amazon Customer

    Takes to long to get hot water to faucets furthest from the tank.hard to keep consistent water temp and it takes quite some time to get hot water to the far side of the house.

  5. Beverlee Larsson

    Love this tankless water heater.The only issue I have is it won’t heat my water as hot as I would like. It says it is at 120 degrees, but I feel like it should be able to get hotter. I like a very hot shower sometimes. Otherwise it does provide tons of hot water, without too long of a wait. I think it takes about 2 minutes for the hot water to get to the farthest shower in my house. Once it is hot, I haven’t been able to make it run out of hot water, yet. Love the streamlined unit, in my garage, too. It looks fantastic!

    Good value, I like is so farDid a self install with help from someone who has installed these before. Pretty easy, took some getting used to since the tank water heater gives you pretty quick hot water response. The tankless has to warm up a bit. We’ve taken multiple showers and run the dishwasher with no problem at this point. The 50 gallon tank that it replaced was 17 years old and didn’t give me any problems. Hoping for at least another 17 of worry free service from this

    The temperature will go above 120!For those that are complaining about the temperature of 120. There is a switch inside the unit that has to be flipped to allow the water temperature to be increased above 120. I run mine at 130 and found the you tube video on which switch to flip. It should also say in the owners manual or side of unit also. UPDATE: 2YEARS unit is still working well! I do an annual descale of the unit, no issues . Good reliable heat for my whole house..

    Works well…This is the 5th Rinnai unit I’ve installed. It works flawlessly as all the others have. The only issue with this install was the gas company had to come out and change the meter regulator. I didn’t have enough gas volume to support the water heater. After that all is fine.
