The unit is perfect. When it works.
Installed in October 2018, worked fine some of the time, until winter when it now works about 2 hours a day at lunchtime. Sometimes it works in one shower and not the other, or sometimes nowhere fat all for a few hours. Fine over summer. Now, I've had the installer out 3 times, then referred to Rinnai. So, no hot water for 3 days now, but apparently someone will come out in 2 days time so, yay. My family of 2 adults and 3 kids aren't needing a warm shower with day temperatures of between 10-16 degrees. 3 calls today to Rinnai, still waiting to hear back from the manager, 5 hours and counting....

too much wasted water
its called instant heat-its a B16- yet it doesn't get to 49 that its set at, not until its wasted 10 to 15 litres in my kitchen- and 20 to 25 litres, in my bathroom- so every day im wasting from 80 to 100 litres now, when on sustainability Victoria says we use an average of 60 litres per day-at a cost of 167 per year, per person, compared to $230 pa, with the bigger gas water unit, system, i got this- B16 to save- cause i was losing 40 litres a day with the big gas unit- now im losing close to a 100 litres a day, and I've got to wait ages, and...its not hot enough to even wash dishes, and I've got to watch cold, to warm water, go down the sink every time, it's very disturbing, and in my opinion, your company should be disclosing that wasted water information, and telling people it will cost more, not less, than a normal water unit because it wastes so much- even if i turn the hot water tap off for 30 seconds, it starts cold again, and wastes another 4,5 or 6 litres again, driving me crackers it is, think im just going to put my old hot water system back again, but to me its very close to false advertising, im pretty sure, confident, that's how a judge would see it too, but whether i could be bothered or not is another story, either way though, you should be telling the people buying them what their actually going to get, and how much waste "this so called instant hot water system wastes", not what you get, after the, "waste", your not talking about.

Poor customer service with Rinnai
Had an issue with faulty value on solar hot water unit which we only had for 15 months. Tried to call Rinnai to book technician to fix problem ASAP however was on hold for 30 mins and couldn't get through so had no choice to go with independent plumber. Still had faulty value available and a massive water bill because of this. As we didn't use Rinnai's technician, this apparently void the warranty. It is appalling Rinnai not prepared to compensate us nor contribute to the cost of the massive water bill. In future will not support Rinnai products.

Terrible temperature and flow
In the summer months it's OK but when it get cold the temperature at best the water is Luke warm and the flow is terrible.
I have had your Tech guy out charged me $190 to say it's not the unit it's the gas company flow from the street they came out said the gas Flow is fine .
I have had the plumber out 3 times thinking he could help he has seen what is happening but can't find anything .
This happened last winter we couldn't afford to call your tec guys again as her said it will cost again now winter here again and here we go again like warm shower again.
So frustrating wish I had money to buy a new brand.

Not hot enough
Our water has never been hot enough. Can wash hair on all hot and hold hand under hot water at kitchen sink. Kitchen sink is close to the unit. Have to boil a kettle for wash up water. How can the temperature be raised please?

Works great..until it doesn’t. No service from Rinnai
2 months before end of warranty our water heater dies. No shower, no washing, nothing. Still cannot get Rinnai to answer a phone. Plumber says it has corroded. Outdoor unit dead after Andre 3 years.Buying BOSCH next time.

Rinnai Touch C1 fault
So on Sat night for no reason the unit stopped working. Kept giving a C1 fault code which is not even listed in the Rinnai install manual or troubleshooting guide. Called Rinnai and operator was clueless. Took all my details at 8am Monday, but when I called back at 4.30pm Monday they hadn’t even logged the job and sent it to a plumber ffs. I found details of the C1 fault on this site and ended up fixing it myself. Remote control needed calibration wth. Fix your install and fault finding manual Rinnai and fix your service. Hopeless.

I have no hot water and can't get a service call.
I have called four times today and had two return calls "to see what I Wanted" and all I want to do is book a service Call! How hard is that?

Not happy with Rinnai B20 unit.
Just recently moved into a new build with a Rinnai B20 50degC unit installed. This is my first experience with continuous flow hot water and I would say that the “B type” builders special units are not as good as a hot water storage unit and I wouldn’t recommend it over a storage type as the hot water temperature can’t be controlled effectively when showering as the minimum flow rate is too high to have a warm shower with a 9L/min shower head as the minimum flow rate on the B20 is 2.4L/min from what I have read which means nearly 1/3rd of the w...ater needs to be hot water which doesn’t work when you just want a warm shower in summer and not a hot shower. This means you effectively have to run the tap as straight hot to “pre-charge” the pipe in between with hot water and then turn it down to the temperature you want for a couple of minutes before the water in the pipe runs out and then swing it back to straight hot again to fill the hot water pipe again. Not my idea of an enjoyable shower. The standard infinity units are probably better as the minimum flow rate rate on these is only 1.5L/min from what I’ve read but it begs the question as to why weren’t the “B type” builders units fitted with the same flow rate switch as the standard infinity unit or is it just a marketing ploy to keep the standard units sales for end user purchases (where the sale is actually analysed and compared against other heating units) and sell “B type” units to project builders who only care about the price and where the end user usually has minimal to no input into the purchasing decision. If so Rinnai are actually doing themselves a big disservice as people will only associate the brand with being unreliable in any new build home where the builders units are fitted and when those people are looking to input into the decision (and they will in the future if they have had issues with their existing unit) they won’t be looking at Rinnai.
Very happy with our Unit, would definitely purchase another!
We purchased ours in 2012 and love our unit. I love being able to adjust the temperature and know my kids and visitors aren't going to get burnt . Great space saver also for the side of our house. We will definitely be looking to purchase another when we move into our new home next month.
i wish i would have purchased a rinnai infinity years before i did.
I purchased a rinnai infinity 26 lpg 60 (6) years ago it is and has been the best (in all respects) hot water system I have ever owned and I have owned a lot over (50) years.
I expect it will not last forever but there is not much that does.
It fired up perfectly the first time it was turned on and has been used a lot in (6) years and keeps on keeping on.
Cheap to run.
this happened to me too!
Finally got a service person to visit and the fan unit is faulty and has to be replaced. Is yours the brand new design with the dark grey contrast sides? Mine is. Service person says a few of these hard a faulty fan unit. Hopefully the replacement with fix it.
Excellent with one oddity....
Quick to fire up, lots of hot water (58-59 C). The only thing that puzzles me is the odd drop in pressure occasionally as it's firing up. Seems if the internal temperature is below some preset it restricts the flow for a moment until the temperature in the heat exchanger has a certain rise. Once warm (as in washing dishes and such) it really doesn't mess around. I'm pleased. Not excited... as it doesn't have as good a warranty as I had hoped, but the price was fair, the installation quick, and I can basically ignore it and know it's going to work.
Some days takes forever to warm up and doesn't get as hot as our pre-existing electric hotwater syst
Seems to always use excess water to warm up and never seems to stay at a constant temperature when on a lower flow rate. Often during a shower water seems to go completely cold and only way to set to a desired temperature again is to turn shower water off and then resetting the water flow of both hot and cold water, very annoying.
We bought rinnai infinity 26 ... everytime we use the hot water after turn the tap off, the unit whistler for 30 seconds ... very strange ! Never had this with my previous unit is. Is this normal because I ring the service people and they say it is the installer, got the installer out no problem with installation ( licences plumber ). We called back to rinnai with the plumber next to me and they couldn’t help us in any way ... is it normal or not ... I bought this unit as it was recommended but whistling Dixie is annoying ... the service team were rude and said $185 call out fee... if deemed installed wrong ... um it is not ... so I need help.
Hate it. Makes me miss our tank water heater.
Have the B26. Since the 1st day it was installed, we've regretted it. Expected the lag, but it uses so much water before it goes hot. Sometimes there is just no hot water at all. Mostly early mornings we need to cross our fingers, but now its during the day and I can't get it on anywhere in the house. The plumber came out twice - nothing wrong. Because it is intermittent, it is a nightmare.
I seriously miss our old tank hot water system. This was supposed to be "the best there is".
Water is not hot and condensation on the solar panel
I have reported condensation issue on my solar panel and we had Rinnai technician came to fix this issue and they still can't fix this issue and going on with this issue for more than a month now. Why not get it replaced Rinnai? It is a brand new installed and within two weeks we noticed this condensation issue as well as water is not hot. I won't be happy till this solar panel is replaced since you already sent technician more than twice on the roof. Is this quality gone so bad?
Similar problem to Sarah
12 years ago I installed a Rinnai 32, we were putting in a new extension on the second floor and the plumber advised me to put in a 20mm pipe instead of a 15mm (standard pipe for hot water), for better flow. (Sarah said she had a 25mm pipe in one of the other reviews). We found that we had the same problem, it took ages for the hot water to come through, I consulted another plumber and he pointed out that the bigger the pipe, the more water sits in the pipe and goes cold when your not using the tap. We reduced the pipe back down to 15mm and it...made a massive difference. Since then I have fallen love my with my Rinnai, it never runs out, its efficient, it hardly takes up any room unlike my last tank and best of all it has never broken down. Sarah's problem is pipe size, try 15mm if possible. regards Tony.
I am starting to get temp fluctuating from hot to luke warm.I have removed the water saving discs in the shower heads. Also not getting hot water through to the vanity.The unit is approximately 8 yrs old and runs on bottled gas. Do these units require servicing at regular intervals.
Had new house built about 8 years ago and didn't stop to think about what sort of gas hot water system they would supply .The cheapskate builder supplied a Vulcan storage type ,was a bulky tank stuck on the side of the wall and even though i turned the heat control all the way up could only get lukewarm water from day one.
In the summer time wasn't too bad but in winter time not good at all .Decided to get the Rinnai 26 back in June from The Gas Works at Morphetvale ,the whole process was absolutely painless ,best tradies i have encountered i...
Questions & Answers
Rinnai 16 infinity is only delivering water at 30 degrees
Hi Steve L,
Thank you for getting in touch,
Please contact our Technical team on 1300 555 545 option 3 and they may be able to assist, alternatively, If a service call is required they can help organise this also.
Our rinnai infinity 24 gas hot water goes cold then hot then cold we wait nearly 15 mins to see if it’s going to heat but no what do you think the problem is
Your gas pipe needs updating. Its not large enough to handle instantaneous flow. I mentioned that in my post.
Rinnai should have this stated on their website. They don't because it would deter sales. Its not as simple as just changing over. Get a LPG unit. Would save you monthly gas service charges if you only use it for hot water.
Thanks for the question, there are a number of reasons for the symptoms you have stated. Our technical team can troubleshoot over the phone on 1300 555 545 option 3. They will need the model and serial number of the unit which can be found on the data plate on the left hand side of the unit.
How to fix a big noise when turn off a miser. I just installed a Rinnai infinity 26 hot water unit about 5 weeks ago.
You are probably talking about mixer , correct me if I am wrong. This is the same issue I am experiencing. It is a manufacturer fault and you can return the unit. Rinnai have not address this due to cost. They only deal with complaints. The noise especially during lockdown is unbearable. I have now switched to electric hot water, MicroHeat 3 phase. I have both installed. The noise from Rinnai is unbearable.
Mixer is a basin mixer tap (It is like a basin water tap). Sorry, I was describing a basin water tap unclear.
I just installed a Rinnai infinity 26 hot water unit about 5 weeks ago then when using it, I turned on a basin mixer tap was good but turned it off the noise was coming from outside of the wall. Do you know what wrong is it?
Thank you very much for your comments.
