Would not recommend
This is the second one we have purchased
It seems they only last for 10 years and they die so I guess if you purchase one be prepared to replace every 10 years
I didn’t think I would have to replace a hot water system so often
They say they last for 25 years but I would not believe it
I am going to try another brand
Plumber installed all new valves, pipes and new hot water system; no hot water came out, tested gas pressure and was all ok. Again, no hot water came out.
Called Rinnai and no support was given. Staff were rude and not helpful at all. We were left with no hot water.
Never buy Rinnai hot water systems, absolute garbage.
Loud whirring noise
Purchased to replace storage gas system. Last experience with instantaneous gas was with pilot light and burner in a small 2 bed unit which worked well.
First thing one has to do, is replace the mains gas line into the property to a larger size, otherwise it wont function properly. The problems a lot of reviewers experience in fluctuation of water temperature is a result of this. Rinnai should have this clearly stated on their website or retailers.

No Customer Service
Wow having read all these issues one thing really stands out..... customer service is non-existent just an automated response which does nothing to solve the issues or help the customer.
I'm not even going to bother adding my complaint.
I will just never buy a Rinnai product again.

Love the continuous flow of hot water
We had our Infinity only installed a couple of months ago after our previous hot water service stopped working. I have not had a continuous hot water service before however we decided to go for this type as with 4 of us in the house even when keeping showers short, there have been times we have run out of hot water. I am pleasantly surprised how effective it is and whilst it was explained to us that the hot water will take a few seconds longer to come through than what we had before, this has not been something significant and we don't notice ...it. We have only all showered close to the same time once since having this installed and I am pleased to say we all had hot water. One element that brought us over to this brand in comparison to another was the 25 year warranty offered.

Hi I have Rinnai infinity 26 (REU-V2626W(50)-AK), This system default temp 50 degree Celsius, I tried to decrease the temperature to 25 / 30 degree Celsius via dip switch. but I couldn't. The manual show only decrease 40 degree, can I decrease or not

Rinnai Life expectancy excellent
I installed a Rinnai Infinity 26 17 years ago.
Trouble free until today, Water leakage from corroded part.
Due to the age of unit it is cheaper to totally replacement of the unit at which I have gone with a Rinnai builder's series 26 60 degree unit with extended warranty for 15 years on heat exchanger and installation of 2 controllers to extend warranty to 5 years.
Later on down the track I will install a Rinnai Hi-Line solar system and install the outlet to the gas B26.
Rinnai are the Leading manufacturers in Hot Water Units gas or electric....Support Rinnai as most plumbing contractors do. Sincerely Peter Kothstein 0412984116
Terrible experience use cheap hosing that rusts
Does not cope always waiting ages for hot water.
Ribbed hosing rusted after only 5 years of use and started leaking like a sieve.
Plumber told me they have had many issues with this hose.
Annode had to be replaced after 2 years use.
They would not reimburse me to change the ribbed hosing to copper which is what it should have been in the first place.
We are pensioners and we cannot afford this additional cost.

Its a great hot water unit
so my previous Rinnai Infinitity 26 was installed in 2004 - we moved into this house in 2007 and the water heater failed a couple of days ago - so that's 16 years of trouble free use - my particular unit is the exterior model mounted outside on a southerly facing wall - with a single wired remote unit.
As Adelaide water is pretty "rough" this was a good innings from the unit. I decided to replace the old unit with a new one exactly the same - and a gas fitter exchanged the unit in under an hour using new fittings.
I am very ...happy with by hot water unit - but I see a lot of questions an poo r reviews. I'd just like to comment on what might be happening in those other reviewers situation. If you are used to a older hot water service - you know - a 135Litre tank - you might have to change how you use your hot water unit - normally with the older storage units the temperature the water is heated to is fixed and you get your desired water temperature and flow by mixing hot and cold water together by using a mixer tap. The advantage of an instant hot water service is that you can set the temperature it heats to and only heat the amount of water you need to the temperature you want.

Cold & cruddy
Model Rinnai B26 A2626WB-50-AK
This unit is COLD, 20 degree day & I just had an only hot water shower & did not get warm at all from my COLD supply of water. I will have to purchase a thermometer & see the actual temp from faucet but you can stand under all hot from this unit without even feeling mild discomfort. Installed sheltered area. Looking forward to developing a hatred of Rinnai over the warranty period...
2 questions posed - Copes well with high demand & extended usage
- Does have issues with fluctuation but may not be due to hot water system
Purchased in November 2019 for A$800.00.
Super efficient gas water heater, some lessons though
Replaced an old mains gas storage heater with an Rinnai Infinity 26 with controllers to set temp. Great news is my gas consumption fell 90% (not a typo).
Some lessons though.
Had to replace the mains gas line into the property to a larger size, ie less gas consumed but at a much higher rate.
Low flow taps/shower heads appear to confuse the heater (hence some poor reviews i guess), solution is to turn on hot tap much more seems to solve problem.
Have had the unit for almost two years, faultless and highly recommended.
However, given the cost of gas main replacement and gas retailers quarterly connection fee, it would have been more cheaper to go LPG option. QLD fee is almost $100 per quarter plus my $10 gas usage.

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.

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.
Purchased in February 2018.
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.
Questions & Answers
Every time we have a power outage, after the power is restored, it's really hard to get hot water working again. I have to play around with the wireless remote control and turn on taps for over 20 minutes before it manages to ignite again.
Once ignited, it works fine until the next power outage... What causes it to be so hard to start again?
Had identical problem ! I guess the transceiver trips out and needs to be reset. You really don't need the remote at all. Just disconnect the transceiver cable at the quick connect (where the wire from the unit connects to the cable from the transceiver). The unit defaults to 50 degC and is hot enough and what's more still works after any power outage, almost instantaneously!
Thanks for the question, we would recommend contacting our Technical Department to discuss this matter further. They can be reached on 1300 555 545 (option 3).
The plumber just fitted a rinnai 26B 50° The water comes out at 40° Can you tell me this is normal The plumber press couple of buttons inside of the machine to the settings 5 F and the temperature still same Just warm no hot
Perhaps your hot water pipes are not insulated and you are getting heat loss through the surfaces. There will always be a heat loss in any system although 10 degC (25% ) is a lot!
Ring Rinnai service.
PS what do you mean by 5 F ? and how did you measure the temperature?
Hi Joe, it sounds like the plumber has tried to make adjustments to the unit to combat the heat loss which can be done with the 50 degree models. He should be testing the temperature at the first bathroom to ensure you are getting true 50 degrees at the tap.
You can call our technical help desk who may be able to offer some advice, they are available on 1300 555 545 option 3,
I have just moved in ,have continuous flow gas hot water, run water for ages & no hot water, power is switched on, what is the problem?
Hi Ikg80, thanks for the question. There can be a number of reasons the unit is not producing hot water. We would recommend checking the power point is working by plugging in another appliance and checking that both the water and gas supply to the unit are switched on.
We have a technical help desk that can help on 1300 555 545 option 3.
