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.

Thank you the review Mitch. Infinity 20 heating to 60 C has a maximum water flow rate of 11.5 litres per minute.
When the hot tap is initially opened the heater will allow all of the water to flow, w...
Read moreithin a second or two the heater will calculate what temperature is required and also adjust the water flow down to match the output.Sounds like I'm looking for a kitchen controller and a bathroom controller! Thanks!! (Thumbs UP!!!)
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.

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".

UPDATE- I spoke to Rinnai technical support who were quite helpful. I got enough information to go back a third time to the plumber. Seems ok now however will wait and see.
Thank you for your update Amanda. We are pleased to hear our Technical support were able to help you with the information required.

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?

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...
Read more 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.- Date Purchased
Thanks for the review Tony P, your plumber is correct pipe size and the length of pipe the water needs to travel to the outlet makes a big difference to the amount of water that needs to be expelled. ...

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.

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

Thanks for the review Crazykleetus, it's true that flow restriction is usually the biggest issue people face with these type of units. Removing the restriction or installing controllers fix most of these problems.

We just had this system installed to replace a gas storage system. It's working great so far: very hot water, on demand. The water stays nice and hot; you can set it higher than the recommended temperature at installation (45C I think?), and I thought I'd need to, but it's been hot enough for me -- even in the room furthest away. We don't have high demand (2 people) or run the unit for long (water-saving mentality!). Can't wait to get my next gas bill to see how much we're saving.

Thanks for the review CH1, there is a limit of 50 degrees for hot water deliver in bathroom areas which is a lot hotter than people realise. We are glad to hear the unit is working well for you.
This unit is a work horse, no problems, no issues, it was installed properly the first time and for the last 5 years it has just worked and worked; I would say, one really has to make sure the product is right for what you using and then I would advise to get a good tradesman to recommend and install the units. Good tradesman are getting harder to find so good luck with that.

Thanks for the review Alex, your advice is very true, getting the right unit for your needs is very important and the right tradesman to make sure the job is done right.

The unit, just after 12 months, started to fail to ignite. Turned the hot water on and off for half an hour or so before it worked. It has stopped again, several times, when not run for a day or two.. Its now stopped again and I can't get it to work. Can smell the gas turning on but its not igniting.
Cold weather and absents seems to upset it.
It really upsets me.

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.

After contacting Rinnai things went from bad to worse. They contacted Jordans (their agent) who sent out a technician. In the morning of his visit when the temperature was around 5 degrees Celsius the...
Read more amount of gas coming out when the unit started so excessive that it was coming inside our house. By the time the technician came out around midday, the temperature was around 25 degrees. Although gas was still coming out it was not as excessive as in the morning but still noticeable. The technician claimed that the unit was working properly and it was normal for the gas to come out, just like exhaust fume from a car. All I know that if my car ejected that much exhaust fume, it would not be roadworthy. From time to time we still get an unacceptable amount of gas coming out and our gas bill has skyrocketed. We would have been much better off staying with the old style off peak electric water heater. To rub salt in the wound, a month later we received a statement (the actual invoice never arrived) from Jordans for a $195.00 call out fee. We have been sending bot Rinnai and Jordans e-mails asking them to sort this out as it is a warranty matter since then and neither party is responding, and the overdue statements are still coming.I have an solar hot water system with an Rinnai solar 20 gas booster. I have had issues with it not getting hot enough. I have checked temps in the bathroom and kitchen which are struggling to get to 40deg's. I checked the temp at the closest tape which is in the laundry, it only gets to 45deg's. Is there some way I can increase temperature to 50deg's +??

Read moreroom to boost the temperature and this should have been completed at the commissioning stage of the installation. It allows for a true 50 degrees at the first bathroom tap. We would recommend asking the installing plumber to return and adjust the unit for you. If they have any issues they can contact our Technical Help Desk while on site to discuss.

Very happy with our Rinnai Infinity 16. Previously had a Bosch hydropowered which was very temperamental especially in the colder months. But not the infinity. Very reliable and consistent hot water. We did not purchase the temp controller, but did have a temp valve installed so we could have the unit preset at 60 degrees. Highly recomend this product.

Had a temp controlled (50 degree) Infinity 20 installed a few weeks ago. Using a pool thermometer the delivered to shower temp seems to be around 38-40 degrees (just tolerable in winter - saving on gas and water tho as not hot enough to hang around). Contacted plumber who advises unit cannot be adjusted and to ring Rinnai. I ring Rinnai technical support, who, after a 40 minute wait in the queue, could not have appeared to be any less interested and suggested I ring the plumber. On current experience stay away from this unit/supplier.

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.

We have had the B20 for about 2 years and have nothing but problems with it, having a shower and the hot water cutting out half way through, our plumber could not find a fault so Rinnai came out after insisting we pay a call out fee of $198.00, yes $198.00 CALL OUT FEE, they said it was our shower heads causing the problem but the same thing happens even when trying to fill the kitchen sink just to wash the dishes, piece of crap, ive clicked 1 star because there isn't a no star option

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...
Read more 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.- Date Purchased
After reading other reviews there seems to be a consensus that the B20 has an inherent problem with no hot water at all especially when cold weather sets in. I had the plumber who installed it check it, he said it was ok. I had gas company check gas flow and that was ok. Then today there was no water flow at all again. Not happy wouldn't recommend Rinnai.

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!

Thanks for the great review Karen, we are so pleased to hear the unit has been such a success. Correct installation makes all the difference and it's great to hear your plumber had done his homework regarding the pipework upgrade.
My B16 unit is only 5 years old, it works fine during summer but when the temperature drops and we turn the hot water on the pipes groan and there is no water pressure at all, after the sun comes up and the unit gets a little heat it’s all good again.
