Wish I had seen these reviews before I bought this lemon
We built our new house 5 years ago, the unit worked ok for the first winter (we shifted in late July, live in North Queensland and do not need hot showers in summer). Every winter since we do not get even warm water, have contacted Rinnai before and they told us to contact the company we bought unit from, have had them to look at item and they cannot get it to work any better, there are only two of us in the house so this unit should be able to keep up with our usage. We have not been able to have a WARM shower for 4 years I am fed up with it but cannot afford to buy a new unit.
Do Not Buy These Heaters.

HOTFLO 10 - Rubbish!!
Had nothing but trouble with this water heater, since installed by a Licensed Plumber. Had numerous callouts, and now the water is lukewarm at best. Tried everything. It's definitely not the water or gas pressure as both are excellent. New battery and still the same old problem. Call a technician and pay $300 just for a call out. Do not buy this product, it is absolute rubbish.

Do not buy this product
Bought this product to replace an old gas hot water system. My plumber took it out of the box and went to fit the regulator and the pipe sheared clean off. Both of us were stunned at how brittle the pipe was, it seemed porous.
We have been given a complete run around by Rinnai customer service and their hopeless Sydney Service provider D&N plumbing. We were told our case was a priority case to be actioned but I never received any call and have spent the entire day chasing them to get someone to come out to fix the faulty product. We received ...no call from D&N plumbing and they have just ignored our calls. We've had to continually call Rinnai to try to get this fixed but have been told to wait another 3 days as they will not pay the call out fee for D&N plumbing. I cannot stress enough how much we regret ever having the misfortune of dealing with them and this faulty, dangerous product. Save yourself the hassle and stay well clear. I wish I had seen their reviews prior to buying this product. Hopefully this review and the other ones will save someone the hassle of what we are going through.

No issues whatsoever, easy installation and solid hot water
I saw all the negative comments here and decided to let everyone know that my Rinnai electric HOTFLO 250L purchased July 2019 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.

Extremely Poor Product
After almost 20 years, the Dux Everhot had to be replaced. Was replaced with a Rinnai (plumber's choice) on 18/3/2018. Model No EHFA250536 Serial No 5008431 Date of Manufacture 10/10/2017. This worked for about 4 months then we were away for 4 months. About December 2018, we noticed some intermittent heating issues and replaced Mains Fuses thinking this was the issue as the hot water cylinder was supposed to be new. We were away again till end March 2019 and since then have had increasing problems, until now, we have no hot water at all. Have h...ad an independent electrician check all wiring and fuse box/switchboard but consensus is that the cylinder is at fault. Not surprisingly, the plumber has avoided our calls and messages, probably being aware that this product is sub-standard to say the least. The cylinder has had less than 8 months use, generally 1 person, sometimes 2 at the household. Have spoken to 2 other registered plumbers and they agree the cylinder is at fault and pointed us in the general direction of these reviews. Well, add another!! This is a terrible product and our after-sales service has been non-existent. We, however, are not prepared to stand by and let this go away and will be placing the matter in the hands of the ACCC. This product is known to be unreliable and faulty and there appears to be no after sales services or upholding of warranty. Buyer Beware!!! Do not install one of these cylinders!! They should have been recalled after the first set of bad reviews received. It is a very poor testament to the company that this product continued to be sold.

We had Rinnai Hotflow 250 installed 10 months ago. This week the heater element burnt out within the 1 year warranty period. Rinnai insists that their technician inspect and replace rather than the installer ( who came out to inspect 2 hours after phoning by the way ) Problem is they don't contact you and any attempts to phone them are met by a girl who "just takes messages" Meanwhile you and your family are without any hot water.due to a shoddy part which is supposed to last many years burning out within one. Your only alternative it seems is ...to pay for the replacement yourself which I suspect a lot of customers do. April 9th 2019 Update: Follow up on Warranty Useless The staff at Rinnai are inefficient, uncoordinated and incompetent. The installer and I gave them all the details 3 times in 2 days and in follow up calls they couldn't find any details. Wasted hours getting through on phone and waiting for callbacks that never came. Even got a recorded message asking if we were happy with their service and presuming I wouldn't need them again. What a joke.! After 3 days without hot water for my family and getting nowhere with Rinnai, the installer AC Plumbing came through and completed the work. We would have been weeks waiting for Rinnai to get its act together and I think any reasonable arbiter would agree I made the right decision. I cannot praise AC Plumbing, Strathpine highly enough bcs they did the work without charge and deserve to be compensated by Rinnai.

DEOSNT WORK 3 YEARS OLD TO THE DAY..
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..
Stay away from Rinnai, bad product, bad service
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.
It does the job well
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).
Not enough for 4 persons to shawer...
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.
What a dud
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.
seems to a common theme lack of hot water! now what do i do
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.
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.
Buyers be aware
Bought this system 13 months ago . Had very cool hot water on Thursday and then no hot water on the Friday rang the supplier who said it would be one of three things 1. Missed boost 2. Element faulty, or thermostat gone.. he advise that we could call a plumber or electrician either way we would have to get some one out. So $236.50 later and after getting it fixed over the weekend we then we rang rinnai to see about claiming it under warranty who now inform us that sorry you should have called us first. We explained that we called the supplie...r who installed it and he gave us a number for the electrician. Rinnai don't want anything to do with us now as we did not ring them first. What a take even the electrician told us the thermostat was faulty. You expect to get more than 13 months out of a brand new hot water system. Would never buy a rinnai product again . They brag about their customer service. That's a joke So if contempating on getting a new hot water service find out all about it before you buy. Customer service seems no longer to exist and your warranty is no longer worth the paper it is written on as they always have a way of getting out of it. What ever happened to the saying we stand behind our product now they run away from it . Ever stop to think these days you get better warranty and service for a toaster these days but nothing on the high end products . ,

Chinese made garbage.
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.

Nothing but trouble.
It was ok for the first 6 months or so but then started playing up. We would run out of hot water after hardly using any hot water. We would shower ourselves and the kids then go to work for the day, then come home in the evening to no hot water. This is a 400L system may I add. This problem was sporadic, occuring one day then everything would work fine for a few days, maybe a week before happening again. We were also noticing it was dumping alot of water onto the ground. We changed to Off Peak 2 (so water was heated twice a day) and still runn...ing out of hot water, despite not being home all day and not using it. The plumbers had no idea why it was doing this and tried a number of problem solving methods such as changing pressure valves and such, but nothing worked. We were informed if we wanted the Rinnai technician out to look at it and nothing was found to be wrong it would cost us around $200. It only came with a 12 month warranty (which for a product that is meant to last 10-15 years is ridiculous); and we were at the end of our warranty with a faulty HWS. Luckily for us the plumbing company we bought it from treated us well and replaced it with another brand of HWS. Probably partly because they were sick of hearing from us every fortnight complaining and asking them to come back to fix it.
This unit is supposed to be for off grid installation.
Installed less than 3 months ago.
We have our gravity feed tank 20 metres above the hot water service - I can shoot a 50mm stream of water more than 5 metres in the air from the pressure we have - however the hotflow barely puts out 30% of the pressure of the cold water line - which is identical. It is not designed for anything other than town pressure - a complete fail for its design.
Also - yes - you don't get hot water, you get warm water at best. We have a $200 caravan hws off ebay ...
Questions & Answers
We have no issue with hot water when it fires up!! Our issue is we have to remove front cover and light up with a lighter...battery ok and sparks but wont fire up without using the lighter.
Hi Axel,S, thanks for the question. We would recommend talking to our technical help desk on 1300 555 545 option 3.
Rennai Hotflow Hot water system was installed by a plumber in May 2013. It started dripping slowly a few months ago and now increased flowing continuously from top of the cylinder! I read that Cylinder has 10 year warranty/ 7 year labour and could you please advise me what is the next step! Thanks
Hi Jay, thanks for the question. Booking a service call so we can diagnose the issue with the unit would be the next step.
You can book the service call online here and you will be contacted by the technician to book an appointment:
The current warranty for the Hotflo unit is 7 or 10 years depending on the size of the tank and 3 years labour warranty. The warranty applicable for your unit will depend on the model number and date of manufacture and can be confirmed in the warranty booklet supplied with the heater or through our service line on 1300 555 545.
Thanks, it's model is HFE315 ?SSL? and S/N is EHF31500468
Could you please confirm if cylinder warranty is covered!
Yesterday I contacted 'Rams' plumbing Toowoomba(installer) and was advised to contact Rinnai with model/ Serial # (model is HFE315 ?SSL? and S/N is EHF31500468)
If you could confirm what is next step is? What I want is not calling a plumber/ technician who charges couple hundred dollars and and say 'you have to replace' the unit!
So appreciate very much if this unit (model is HFE315 ?SSL? and S/N is EHF31500468 )which was installed in May 2013 is covered!
I purchased a Rinnai 125 HOTFLO water heater less than 18 months ago and had it installed by a licensed plumber. Yesterday I noticed it is seeping water out of the cylinder bottom circumference seam and causing that seam and small nut to begin to rust. I have called Rinnai today and had to wait so long, then spoke to a technician, who said this definitely should not be happening, and the cylinder is still under warranty. He re-directed me back to the "bookings" switch, but I never got answered. I request that I am called back urgently, before this problem gets any worse. I had my previous water heater in the same spot for 15 years without anything like this happening. From above reviews it seems like this system has problems. Either way, I want Rinnai to fix this problem. It is definitely a product fault.
Hi Jan J,
Thanks for the question, you can make a booking through the Rinnai website here:
Alternatively if you can send us a private message with your contact details we can have one of the team contact you.
I have received the email and when I click on to the website https: the form does not eventuate, the page just continues to talk about conditions and costs. So I have then tried to get the form on CONTACT. This gives me the form, but when I try to enter my NAME etc. the form disappears! What is going on ? Please contact me again through my email and I will give my private phone number so your staff can contact me personally.
Hi Jan, can you please send a private message with your contact details as we do not have your email address.
