Rinnai Infinity 16

Great unit well packed safety and secure No issue at all Show reply

Rinnai Infinity 16 Bad hot water system – It doesn't work as advertised. The hot water is not enyto have a shower. It's only last about 6 minutes and the rest is cold water running out. NOT HAPPY. It's totally crappy quality, DON'T BUY IT. It's not worth it. 1/2 a star if possible. Just get a Rheem hot water tank would be better and for sure will have enough hot water for shower. Nothing worst than having cold shower in winter in Melbourne.

Not Happy – 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.  Show details

Just reliable hot water every time! – 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.  Show details ·  1

B16 doesn’t work during winter – 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.  Show details

Fluctuating water temperature – We have had the Rinnai 16 for a number of years, has been ok but a little temperamental with water fluctuating in the taps. Taps can only run on hot or cold alone, otherwise as soon as the temperature is balanced the hot water will turn off. Recently our shower has started fluctuating from very hot to cold, I can see the wall control operation… Read more

light turning on and off.

Do you know what the problem would be?

Ps I did leave this question in the Q&A section however my question disappeared. Thanks

Very good – This water heater has been very good with no trouble at all the gas usage has been significantly less than the last continuous flow heater that this replaced we also splurged and had the controllers installed one general and one bathroom it is a real luxury to have a shower and not have to mix the hot water, we have a small house and while… Read more ·  1

showering if another hot or cold tap is turned on there is no difference in the shower temperature just a bit less flow

Not user friendly. Intermittent hot water – Had the 16 installed (no remote, no visible controls aside from the intake valves) approx a year ago, has been fine until now. All of a sudden I am not getting any hot water at all. It is just a couple of feet away from my kitchen and despite running the hot water tap for a minute or more, I get no hot water. I was told by the plumber at the… Read more

time of installation, that if I did have any trouble with the unit, to simply switch off the power supply then turn it back on again.

I tried this and it did not help. It has been 4 days now of no hot water. Prior to that it had gone out for 3 days, but then randomly worked again for 1 day.

There is no way that I can access inside the unit to check the pilot light as it is fully sealed and there is no panel to see any error codes.

I cannot recall which unit I had previously, but I wish I had the same one because at least then when the hot water did go out, all I had to do was go relight the pilot light and open the hot water tap to boot it up.

I am on a very low income and cannot afford for a plumber to come out, not to mention that it would be very embarrassing and frustrating if he/she arrived to investigate then the hot water was working fine at that moment, then stopped working again after he/she leaves.

It would be great if I could find some information online that is not in pdf form, on how to troubleshoot the problem. All the info I have found so far only refers to units with remote controls/ error codes.

Not happy – Bought a brand new house and moved in 4 weeks ago and the builder installed the 16 unit per the developer. The hot water seems to come through quicker in the shower but the basic vanity tap seems to take ages and wastes a lot of water. This is also the case in my kitchen - not happy as want instant hot water and no wastage of water.  Show details

Ok when weather is warm, doesn't work in the cold – Had two B16s installed during renovations, one for the bathroom and one for the ensuite. We get plenty of reliable hot water for a family of five people -but only for 8 months of the year. As soon the temperature starts to go below 12-15°c the continuous flow hws starts to struggle and alternates between just warm and freezing cold. I dont… Read more

live in Antarctica either... I think its fair to think my two hws should work in metro Adelaide during the cooler months?

Occasionally with just the correct amount of twizzling on the mixer tap you can find a sweet spot where the water flows at a reasonable temperature.

Also, when this is happening the exaust gets a sickly gas smell like it is running rich or not properly burning all of its gas.

Apart from that its great.

The Best – We installed an infinity 16 in our motorhome so it gets shaken and bashed as well as dust, salt air and very extreme heat and cold. It's still working like the day we installed it over 13 years ago. The deluxe controllers give is the power to save water as well when living on a water tank. Not to mention we have many children on board so… Read more ·  1

it's made our travel life so much more comfortable. We wouldn't recommend anything else and if it ever fails we'll be buying another Rinnai.

Great system – Fantastic Ihave a B16, not an infinity 16- not sure of the difference, but its always hot and the pressure is always there. Not had a problem with mine. Its actually hotter than the last heater which was a 20 year old Bosch, plumber recommend Rinnai, even though it was a bit more cost than the Bosch  Show details ·  1

2 stars for the hot shower! – Apparently, Rinnai used to market these hot water systems as instantaneous heat. We all know that's not true as it takes a while to push hot water through as the pipes are cold. So they changed it to continuous hot water which is true at full throttle. The minute you turn the tap off and then you want more hot water it is cold again. So, I… Read more

have tried running it at a slower rate but it goes cold because the flame does not ignite if not full throttle (this is feedback from Rinnai via my plumber.) Now I always have a sink of cold water as I like to rinse in hot water and have only one sink. I have had this unit for three months.

It is fine having a shower because water is always on full throttle.

Beware of Rinnai if you have problems. They did not even want to know what the problem was with the unit, as they only wanted to explain their warranty terms and service charges. The service pitch to begin is, basically, I only work here and am reading out to you warranty terms: If problem is not within the warranty, then it is a $195 call out fee with first 45 minutes. Then $35 for every 15 minutes after. If you need parts that are not within the warranty then you must pay on the spot. If you pay by credit card it's a 1% surcharge. Now if I had of called them out it would have cost me $195 plus the surcharge. You don't get to speak to a someone who has mechanical/electonic experience with these units to explain what is going on. Just a warranty pitch and service charges. Poor customer service as far as I am concerned.

I was lucky and have had a good plumber, who came out and dealt with this free of charge.

Love our new Rinnai Infinity 16! – After owning a Bosch hydro unit for 20+ years (amazingly reliable) it was time to get a new water heater because we were at most, getting only very warm (not hot water) and with winter on the way, we needed to act fast. We chose the Rinnai Infinity 16. We walked into Gas Works on a Monday, bought the unit (it came with the Universal Controller)… Read more ·  3

and it was installed (by plumber and electrician) the very next day. Love the controller... we set our preferred temperature and just turn on the hot water tap and we get continuous hot water at that temperature, with no need to turn on the cold water tap to fiddle around trying to get the right temp. Love it! Hopefully, it will prove to be reliable.

Its fantastic to have hot water running again after having a BOSCH unit that was utterly hopeless – Finally had the Infinity 16 installed and its been great. Had it about a month or so. Had to pay $87 for the quote and was told I would get that $87 back if I decided to buy the product. Cost $3249 which includes installation. Went with the Rinnai company who then contacted their plumber here in Perth WA. I didn't get the $87 back. The hot… Read more ·  4

water system takes maybe 10 seconds to heat up and stays hot no matter how long I have the shower on. The BOSCH units are to be avoided as they often turn off halfway into a shower and just designed to fail.

Anyway really thrilled with having hot showers again and able to wash the dishes without the need to have the kettle going to wash pans and stuff.

Know quite a few with the infinity 26 where they had one for months and never a problem. Get what you pay for in life.

No complaints from me.

Contact Rinnai to get their people out to do the quite and pay the $87.

Rinnai Total Rubbish – I have had electric water all my life and never had a problem. I changed to gas water because of a promotion and was told that the gas hot water is cheaper to run and the water temp is good. I have had the Rinnai hot just over two years and I'm am so not happy. The hot water takes so long to heat up and the temp fluctuates. I had rang Rinnai and… Read more

got me to reset the water unit and nothing happen. they told me it's $132 and then $33 after 15 minutes, what a joke. I'm going to have the unit ripped out and put an electric water back.

Read the scary stories, but the Rinnai 16 is great – Had an instantaneous unit for 35 years, then it died. Read all the negative stuff about all alternatives and was very nervous. I have a 3/8th inch long gas-pipe and gravity feed low-pressure tank water supply. The Rinnai 16 worked straight away, without a problem. It's even better than the old unit because it has a thermostat and no pilot light.… Read more ·  1

Always the same temperature that won't burn the grandkids, but is hot enough for the dishes. Cost $260 for the gas fitter/plumber. Couldn't be happier, as long as it lasts for quite a few years yet.

Extremely disappointing – We had this model installed in March 2015 to service our ensuite which is at the far end of the house from the electric system and it took too long for hot water to reach it. We find that it is marginally improved in the shower but little different in the basin, and for this slight improvement it was simply a waste of money. Contacting the ACTEWAGL shop did not prove helpful.

Smells of Gas and doesnt heat water and goes hot and cold – Terrible smell of gas gets pushed out.from.the vent. Doesnt feel hot enough to wash dishes not hot enough to remove grease and goes hot n cold all the time when showering. B16. Worst one put in government housing. Must be cheap. No pilot light to save gas money but how much power is used running it. False economy!
