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.

24 Years trouble free operation
Infinity 20 installed in 1996 replacing an inefficient solar system. Heavy use family home with two bathrooms and it has performed wonderfully during all this time. Had it serviced after about 5 years and was told not to bother again unless there was a problem and there have been none until today. Cost of the unit and installation was approx 30% of a replacement solar system and running costs have been cheaper than the electric boosted old solar unit. Flow rate to two showers at one time is a little reduced but still satisfactory although one shower is perfect achieving water temperatures in excess of my tolerance levels if required !! Cannot rate the unit to highly.

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.
WOW I Love it!
Had it now for 5 days and it is great.I had a 20 liter before but chose a 16 liter this time and no difference.After shopping around I found this Rinnai to be best value and it looks like a sport's car compared to other brands.The guy at the shop said they never have a problem with customers who buy these.This unit was just a bit more expensive than other's but I found it to be a bargain for what it is.I have it set on 40 degrees on the controller so I never have to turn on the cold water tap as it is hot enough and no risk of Scolding which is...a worry to Me.It look's really nice and performs very well.I found a plumber for $350 to install that took him 40 minutes,easy money but other's were as high as $900 so be care full who You get to install as they are rip off's.

Have to disconnect the remote if your power goes off
When your power goes off we have to reset the new controller and turn it back on otherwise the heater will not turn on. This is a pain as sometimes you don't know when the power goes off in the middle of the night and then comes back on so when you go and have a shower in the morning there is no hot water. As we have 2 bathrooms we have the controller in a central part of the house so we have to get out the shower and go turn the unit back on total pain... So spoke to service and the only fix is to disconnect the controller on the main unit... What's the point!!! Very disappointed and there is not fix to the problem. Our older unit would turn itself on when the power came back on not this new one you have to manually turn it on.

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.

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

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.
Hot and Cold
Our B20 unit is 16 months old and it is satisfactory in all respects except for our shower. In a 3 or 4 minute shower it runs cold 2 or 3 times. The instruction book says to increase the hot water flow but it is already at near its maximum. It is very frustrating as out old tank system never caused a problem in 16 years.

Do not get any system like this
Point 1: this system will not provide unlimited hot water, unless you use a high flow shower head. Using the ones they claim are compatible (see point 2) will result in hot water cutting in and out, giving you a hot-then-freezing-cold-then-hot-then-freezing-cold-etc shower that makes you want to tear the pipe out of the wall and beat the hell out of the salesperson who told you how great this system is.
I know, salespeople lying to secure a sale... what a shock..
I'd like to know when all salespeople will be legally responsible for b...

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.

Exceptional hot water unit
I have read a few reviews regarding instantaneous hot water units – I truly feel that everyone needs to understand how an instantaneous unit operates. I would recommend that you get a plumber to inspect the plumbing (pipe size) installed around your house – this due diligence will ensure that you do not end up getting an unsuitable unit installed.
Due to some error code, a Heat Pump will constantly cause the unit to fail, and the energy bill will take a massive hit. A unit that includes a tank will deteriorate as it builds up sediments over t...

Our unit has been running flawlessly for the past 5 years. I installed controllers next to our showers + kitchen and the kids love having easy control of their shower temp. Energy efficient - Gas bill is nice and low - although installation was high (thick copper gas pipes).
Temperature fluctuation is minor when say the washing machine and/or dishwasher kicks in while you're showering, but it's still warm enough and it very rarely happens. On the flip side, you don't run out of hot water (except during a power outage)!
In all, no regrets and would install again.

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.
