Thank you Rinnai very happy with the service of the technician that came out and fixed the problem, was the anode that was incorrectly installed from the start by builder plumber? So happy now thank you so much

I saw all the negative comments here and decided to let everyone know that my Rinnai electric HOTFLO 250L purchased July 2022 is wonderful, good narrow dimensions, made in Australia, Victoria new factory - I did my research. I'm guessing that other customers were ether in minority and/or unlucky and/or products were made in China and all called a plumber instead of calling Rinnai direct and let them guide them through the process. Got good price, $729 delivered and then I organised best installation option - don't let plumbers rip you off please.

our 3 year old Rinnai Instantaneous 10 has stopped working.. called Rinnai and they were hopless.. so much for their "troubleshooting".. they said to call a plumber.. no help at all..Junk product..
Have had a plumber around and he cant work out whats wrong... Aint a cheap excersise.... Said to call Rinnai.. I explained that we did and they said to call a plumber, he had a chuckle at my expence...
No mention from them of warranty?????
stay away from this rubbish product..

Agreed this is very bad service, my tank is rusted I believe, as hot water came out yellowish. When I called them they will not be able to advise whether my tank is still under warranty or not, even I have provided the receipt, model and serial number. They told me to book the technician for $195.00 and they will let me know if it is still under warranty or not.
All I want to know is what is the warranty period for my tank and the storage cylinder of my tank, no you will need to pay $195.00 for that answer. Sad sad sad, I don;t know how Rinnai's customer services be so bad beyond word can be describe.

This is the only hot water heater I have ever needed to buy. The previous one died of old age in mid-winter. I went up a size, from 80L to 125L, mainly for family visits, not because I need the extra capacity every day.
Being without hot water for almost a week (the old one carked it on a freezing Friday night and the supplier with the best price in my regional area didn't have this model in stock) has made me really appreciate reliable hot water.
Running costs are fine for the size. Installation was straightforward. Overall, the whole process cost less than I feared, and less than the Harvey Norman supply and fit package.
No issues at all - it does precisely what it's supposed to, at least at this stage (seven weeks).

I installed a new Rinnai 315L single element unit 2 months ago. from that day, still now we run out of hot water every afternoon. 4 of us in my house. we don't use hot water to wash clothes. when I called their customer service. they asked me to give the credit card detail first to send a technician. very bad customer service. pls don't buy Rinnai product.

Purchased product hotflo 170l, only had it for 18 months, and it leaks and pilot light turns off..,DO NOT CALL Rinnai customer support....you will be charged excessive fees for someone to come out and not fix the problem and still pay the call out fee of $200 and be told that the leak is condensation, turn a pilot light on, which the should have been able to advise over the phone. Avoid at all costs...this customer service report is current as August 2018. I had a rheem for over 15 years and no issue...these leak after 18 months...save your money and do not buy.

We had the Hotflo 10installed in March 2015 and by November 2016 it was subject to a warranty claim, no hot water at all. Subsequent to that claim the system worked until early 2018 at which point it started to play up, no warm at all or lukewarm. We spent a fortune thinking it was batteries. Our water flow is from a large rainwater tank delivered by an excellent pump so pressure is not the issue. At time the system just went on strike. It stopped all together last month for a few days, so I decided against repairs, and have replaced it with a Bosch system, same flow rate and with the added bonus of not requiring any power for ignition, it’s a hydro system. I still have the old Rinnai unit if you guys want to have a look.

right ive just had a house built and been in only 5 month. now my Rinnai 315lt hot water is not hot enough even though its set to 70 degrees. we have to use max hot water at the tap and are still feeling cold as this weather goes cooler.
ok rannai who do I call? the builder of the home? the plumber or you? im not paying a cent either way it goes as ive paid more than the system is worth with the builders markup. no such product should be faulty in such a short time.
ill await reply so I don't get shafted with the you should have contacted us response.
thank you

After only two years of use in a single person household I've just paid $372. to replace the element & thermostat. Oh, & 2 rusted bolts. I'm assured the parts are better quality than the original but betting the manufacturers won't accept responsibility for supplying sub standard parts. Reading other reviews it seems
pointless contacting Rinnai who would say I should have contacted them first. Wonder how long that would have taken to get hot water back on.

Another product made in China and as usual---- garbage.
It was a simple matter of swapping the old unit out, connect the supply and the inlet/outlet pipes.
Yes, extremely simply until the water was turned on and filled the tank all four tapered threads leaked. How long have we humans been making threaded devices, unfortunately the Chinese can't get it right. Checked the threads with a thread gauge and they weren't even close.
If you want to waste time fixing a brand new product then buy Rinnai http://www.rinnai.com.au/

Good price and service.
I had trouble with a Rheem product and didn't want another.
Was delivered at a better price than others without delivery.
Was easy to install and is performing well.

From the day it was installed the water was just warm..Ive had 4 gas plumbers out & the ATCO gas supply guy out(who advised to remove the green tempering gauge which cools the water to the Govt advised temp)..He even changed the regulator at the gas meter, increased the gas press..so with all this done, its still just warm, & the warranties just out..the bathrooms are nearby,but nothing brings the temp up...the ATCO guy said hes seen 4 other complaints with this new model....avoid at ALL costs...go to solar with elec booster & solar PV panels

I have had my Rinnai Hotflo for about two years now ....unknown to me it had been slowly leaking water into to the element box at the base of the cylinder and the floor boards under the Hotflo were soaking wet ...if the element had not blown the whole thing could have gone through the floor boards and what more disturbing is the nice guy who came around to fix it told me this is a common problem with these heaters ...I ask my self why are they not fixing the problem on the factory floor where they make them .....I checked where they are making them and behold it was CHINA ??!! well enough said ...my suggestion is ...Don't buy one ....
