Rinnai Infinity Range

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.

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....

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.

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.

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?

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.

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 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?

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 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.

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.

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.

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".

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?
