Major fail - don’t buy
High pitched squealing noise from frost valves last 90 secs & goes off every few minutes, and runs all night (3 nights so far). You can not sleep with this product. If you happen to doze off it wakes you right back up again. Worst product I have ever had. Rinnai service centre told us Thursday they would call Friday and didn’t. They didn’t care we couldn’t sleep. They are now shut weekends so we can’t follow up until Monday. Hot water is very slow to run - that was just tolerable with water wastage issues. Now with this valve noise issue it is a major fail. Don’t buy!

Terrible noise when using hot water
We’ve had the solar unit in for 8 months and the sacrificial anode has been replaced 3 times in the tank to try and combat the build up of pressure in the tank. To date this has not fixed the issue. We were told that we weren’t using enough hot water, so what happens when you go away for the weekend? The copper water pipes have changed colour due to the excessive heat and plastic around the solar return pipe has melted.
It seems that not enough research and development has gone into this product and we a paying the price for it.

Unreliable product with a guarantee to fail multiple times
Having reliable Rinnai products in the past I thought I would fork out the money for the best efficient hot water system Rinnai offered. I purchased the Sunmaster with the evacuated tubes and instant gas booster. Boy was this a mistake..
The Bad - The system had issues from the day it was installed. Day 1- The first issue was the temperature sensor on the evacuated tube manifold was faulty. The sensor was indicating a high temperature all the time causing the circulating pump to run 24 hours a day. Day 35 - circulating pump started making...a whining noise so Rinnai replaced the pump. Day 89 - noticed the gas booster was running all the time. This would normally happen if there has been no sun for a few days however we have had sunny days for the past week. Discovered the pump to not be turning on during the day. The controller board was not turning on the circulating pump when the temperature sensor on the manifold reached a set temperature. Rinnai replaced controller board. 8 Months after install - another faulty temperature sensor on the evacuated tube causing the pump to run 24 hours a day. Approx 1 year 3 months after install - Gas booster running all the time again and no hot water in the tank. Another faulty controller. This time Rinnai replaced it with a completely different controller. 1 year 9 months - over pressure / temperature valve constantly flowing out scaling hot water..... The circulating pump was not turning off the the tank reached 70 degrees. Rinnai found the sensor in the tank to be faulty which they replaced. It's now been 2 years and 6 months and I'm dreading the day when it fails again. I have connected the instant gas booster to a remote switch so I can remotely turn on the booster if there is no hot water in the tank. This is the only way anyone can tell if the solar system is operational or not. Most people will have no idea their solar system is not operating as the gas or electric booster will completely mask these issues. Rinnai has a lot of quality issues with this system. The use of poor quality, not fit for purpose parts has ultimately lead to the multiple failures I have encountered. To date every component of the solar system has been replaced apart from the evacuated tubes. A thermal camera will quickly identify any issues there. The good- To be fair Rinnai has replaced all these items under warranty. My concern is once the warranty runs out will Rinnai come to the party? If you are reading this chances are you either have issues with your system and are looking for a solution or, you are in the market for a new efficient port quality solar hot water system or, you are Rinnai. I hope this review can assist you with repairing your system or, providing information to assist you into making a informed decision or, providing you with valuable product feedback. The issues I have encountered could be an isolated case however, reading other reviews I doubt this is the case. The review provided is factual and based on actual issues encountered and solutions to those issues.

We built a house and moved in November 2016 with this unit being installed brand new shortly after. Since then the Rinnai Sunmaster (Model: REU-VR1620WS-AK) has been in gradual decline. We first noticed the water starting to take longer and longer to heat up, then the water temperature started to decrease. Next we had an issue with an overflow valve which resulted in the constant flow of water. This was eventually fixed as it is a known fault but it took a couple of calls for them to acknowledge this and more wasted water which resulted in a ri...diculously high water bill. We then had to call Rinnai out again to get out another repair man to look at the issue with the water not heating up and the decline in temperature. By this stage the water was lukewarm and we had resorted to using a kettle for hot water. Turns out it was a problem with two filters that were dirty and needed to be replaced. The repairman said the unit is like a car and needs to be serviced regularly. So $225.00 later and now being advised that we need to have it serviced regularly with 2 people in the house and less than 4 years old...what a joke. We have had other HWS for years (one was over 10 years old) and never had to have it serviced. Stay clear of this model and Rinnai in general if this is their standard.

Still not working five years later
Five years on the unit still does not work and Rinnai seem to have their heads in the sand. The problem appears to be in the sensors, and the PCB. Don’t waste your money!!

Built new house in 2013 and installed rinnai evacuated tube solar hot water system, the system is 6.5 years old and the hot water cylinder has let go, it is leaking and has massive calcium build up inside, my plumber says don't worry warranty will cover, rinnai informs us it's not under warranty as older than 5 years, they basically said bad luck buy a new one, they have longer warrantys now, i got no where with them, they tried to blame our tank water which is not right, we previously lived 2 k's away in same street and had rheem cylinder in...stalled when we built, that lasted 14 years. Never rennai again, no support or help.photos of our 6.5 year old cylinder. People please use rheem or someone else, rennai is rubbish, they contacted 're my review today 2/3/20 and have said they can't help as 6.5 years is outside warranty and blamed our tank water which is a weak excuse, they don't help steer clear from rennai.

2 Units failed within 4.5 years each. Rinnai not interested. Do not recommend.
Failed after 4.5yrs. Rusted at outlet. Replaced under warranty at cost of >$400. Second unit rusted at inlet &failed 4.5yrs later. Rinnai contacted on 3 occasions but totally unhelpful - not interested. Not a water supply issue. Awful & expensive experience.

Worst service ever
My hot water woke up the neighborhood by making a high pitched whine / scream at 4 am. I used the pressure relief valve. The noise stopped. I let go and it returned. So i turned off the whole unit.
I ring rinnai. The first person will not accept my word that i have been in my house a bit over 12 months and the serial number first 4 digits of the serial number mean the unit was now over 2 years old. I needed the certificate of occupancy to show when i got the new house.
I rang back with certificate in hand. After 18 minutes on hold the woman sai...

Nothing but trouble
I purchased this system in September 2017. Since then I have had one tube failure and multiple problems with the pump and control system. The pump is supposed to circulate water from the storage tank through the roof evacuated tube collector when the water in the collector is warmer than the storage tank. Unfortunately the pump often runs all night cooling the hot water in the storage tank.
The controller has been replaced a number of times but the problem keeps recurring. Rinnai have been of no significant help other than in the early days of ...
Rinnai Equinox Hot Water SS330H2EXT
This is merely six years old and the tank is bulging and the external plastic has completely broken away. After 2 and a half weeks I cannot even get someone to look at it. Four calls to Rinnai "service" did not get thru. This company is extremely low on customer focus so we would not recommend anything with a Rinnai brand at all based on what happens when you call for help.

Unreliable not fit for purpose
My unit has now failed for the 9th time in 3 1/2 years. The problem seems to be in the design or manufacture of the pump control system. As a result at night the pumps moves the hot water from the tank and cools it down on the roof. Rinnai are totally unhelpful. The ad hoc solution has been to put a timer in the power supply to the pump so it cannot run at night. To make matters worse the problem is intermittent.

Don't Buy... Will not buy again. Pump Failure, Frost Valves Constantly leaking
18 Month old system was installed on new home and is on 3rd warranty call out. Frost valves leak & have been replaced twice, last set have not lasted 8 months. Pump failed tripping the circuit breaker shutting down all hot water supply in a drizzly cold Victorian evening in July and required our 6 month old daughter to be driven to friends house for several days for bathing until Rinnai sent out a technician to replace.
Requested support from Rinnai on full replacement system however pushed back onto technician suggesting they will provide a solution. Next step ACCC to request full replacement.

Worst product and very unfriendly customer service
It seems the company RINNAI has the policy of pushing their products hook and crook through the builders rather than delivering quality product that withstand changing weather conditions. More worse is their attitude on customer service. My solar hot water flat panel has burst this morning and despite several calls to 1300555545 the person is not registering the fault and does not provide reference number, simply saying that some would call me back. I am stuck now without hot water. It was a similar problem last year, ten days after booking...fault their personnel attended and said they have replaced one of the burst valves. If it is a quality product how does it become faulty in less than a year. If the company is doing thousands of installations in Melbourne suburbs as heard from their personnel why can't the company expand the service level at least during these worst weather events. Do not recommend RINNAI products to anyone.
- Sunmaster Flat Plate System
Not designed for the intended purpose - Split Solar Hot Water Pannel
Well our second Solar Hot water panel has now started leaking just out of the 7 years warrant by 5 months, the first one started leaking in 2015 and was replaced under warranty. Now just after 3 years the replacement panel is now leaking water from the inside again onto the roof.
The system is a Sunmaster by Rinnai with two solar hot water panels on the roof with the Rinnai continuous flow gas boost, the system is not designed for the intended purpose.
A very poor product that should last more than 3 years without fail, I have been quoted $930 for a replacement panel without any labour. This should be still covered under warranty.
Questions & Answers
Hi there. I have a sun master with a gas boost. Every time I go out to see if it’s working the it’s not even when the sun is at its best. I check the display and it says pump fail. The C hot temps say 13 degrees and the T hot temp is 130 degree. I rang your technical team and instructed me to turn the dial up a little due to water not moving through quick enough and boiling in the panel I did months ago and the problem constantly keeps happening. So I call the other day and was told that they know of the problem that it goes into fault when it shouldn’t and that someone has to come around and re program my unit. He put me through to service and they instruct me I have to pay for someone to come around to fix it due to it been over a year old. If you know of a problem then why hasn’t anyone contacted me or my plumber to fix it.
Hi Tim A,
Thank you for your question.
As mentioned by the Rinnai 1st Care team, to be able to assess the unit in question, Rinnai would need to attend site to diagnose the issue. They will then discuss with you what the next steps are and if required they can call our Field Support team from on site if they need further assistance.
The 1st Care team can be contacted on 1300 555 545 to arrange a booking.
Hi, I have a Rinnai Sunmaster. Recently, the solar panel started leaking. I had a plumber come out to help and he found that the solar pump had not been turned on since installation. Would not having the solar pump turned on result in the failure of the solar panel? Thanks, Anthony
Thanks for the question.
We would recommend contacting our Technical team on 1300 555 545 for further advice.
I’ve noticed no noise coming from the Rinnai Pump Assembly Model No. 39001747 for the Solar S26, previously there was a ‘ticking’ sound. Is this normal? Is there something I can check on to ensure the pump assembly is working correctly? Thanks
Thanks for the question, when the pump is operating it will make a whirring electrical sound. If there is no noise check the power point is turned on or open the PTR Valve to see if the tank is hot, if not the pump may be faulty.
Please contact our 1st care service on 1300 555 545 for a service booking.
