Absolutely hate it!
Absolutely terrible HWS. Wastes ridiculous amounts of water to heat up, goes cold during showers several times per shower. Have to turn off cold and leave hot water to heat up during shower after already wasting water and time to heat up in first place. Deters the household from even wanting to shower regularly as it is not a relaxing experience whatsoever.
On and off since its gone in
The hot water takes ages to come through, I'm on bottled gas no flow restrictors anywhere. Been like this since it went in. Plumber not helpful at all. It sometimes works after been thumped on the outside of unit.
Purchased in November 2018 for $429.00.
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?
Purchased in August 2012.
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?
Purchased in November 2013.
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.
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".
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...
Awesome unit. Never had a problem
I’m a Plumber/Gas fitter & Rinnai water heaters are fantastic. I’ve been using an infinity 26 at my home since 2011. Never had a single issue. As for people saying they get hot/cold fluctuations, 90% of the time it’s because you have a flow restrictor in your shower head. Remove the flow restrictor and the water heater will operate correctly
Dangerous and expensive to run, and the warranty is not honoured
We had problems with this unit since we bought it.Especially on colder days the ignition starts several seconds after we turn the hot water tap on, leaving our backyard full of gas and at times it even comes inside our house. When we bought the unit Rinnai forwarded our details to their area agent Jordans Gas Centres to do the installation. They have been out several times to check the unit but could not find the problem. We called Rinnai today who diverted our call back to Jordan's Gas Centres. Despite that the unit being still under warranty and we had problems with it from the beginning, they want our credit card details for payment before they even send someone out to have a look.
All good then no spares
Had installed in brand new house. All good with hot water until one day not hot water. Checked unit and still igniting and couple of days of cold showers then hot again then cold again. Called local electricain who sought help from Rinnai. They explained a small part was the issue. Order put in for part to be later told that its a small part and dont sell spares and units are throw away and suggested buy new unit. Gobsmacked that a 3.5 yr unit is considered throw away....... unit eas hatd wired to power and no longer using gas or solar. Bill prices going up!!
The product is reliable, can change heat to how hot you want. Perfect for young children put it down to 40-41 for showering and I mostly put it to 55 for normal washing. Easy to use. Only complaint would be it does take a while to run hot in parts of the house that are further from the system. Great improvement on our old electric hot water Possibly would consider the enviro smart next time.
Great, has saved us heaps on our gas bill
I have a child with OCD who spends lots if time in the shower, I was worried about the cost increasing in our gas bills when changing to the Infinity 26 model. As well the reviews I read spoke about water and temperature fluctuations so we were concerned, however in the end we took a gamble and in our case it paid off. Our gas bills have been halved, we can now shower in two bathrooms at same time before we couldn't. We installed temperature controls in both bathrooms so we can all shower at our temperatures although if two people are showering...in different bathrooms the main controller sets the temperature, but to us that's ok. We haven't had any issues, the only thing we have to watch is the amount of water flow through our kitchen tap, its a 7.5 lpm per tap so we just turn it to full when using hot water. 6 months in two power bills later the unit is paying for itself.
Much better than I thought!
After reading a few reviews, I was a little worried about switching from a gas storage hot water system to the infinity. However, we have been very impressed! We knew that our pipes needed to be upgraded to larger ones, so we actually had the new unit installed prior to the old one dying, so we had time to switch. The pressure is fantastic- so much so that I can barely tell if another shower , or the washing machine/dishwasher, is being used when I'm having mine. We now also have much more wall space outside, as the infinity is contained in a small unit, rather than the huge tank we had previously. Our plumber who installed the unit is actually considering installing one at his house, as part of his renovations. Thanks Rinnai!

Questions & Answers
i have a problem were when i am in the shower the water is hot then goes cold no one home so no other taps on. i have to turn off then on to get the hot water back, any help?
We recommend contacting our Technical Department to discuss this matter further. They can be reached on
1300 555 545 (option 3).
We have a Rinnai Infinity 26 water heater. It is 11 years old. For the last year it has had a problem of not heating the water all the time. I can be having a shower & all of a sudden it will go cold. Sometimes if I turn the tap off, then on again, it will start to heat again. Do you have an answer as to why this may be happening? It’s in our holiday house, at the beach, so doesn’t get used constantly.
Thanks for the question Sue. It may be an issue with water flow through the unit which can be restricted by a few things. Checking the filter on the bottom of the unit for debris or build up, or in the shower head. Our technical team can advise how to clear the filter and are available on 1300 555 545 option 3.
We had our gas turned off in the recent fires when it was turned back on my continuous gas water is making a loud whistle noise Only when you turn on the hot water in the shower temperature 42 all the other taps are fine??
Thanks for the question Chris, our technical help desk have advised it may be an fault with a washer in the shower and have suggested replacing them to see if this rectifies the issue.
