2 Units failed within 4.5 years each. Rinnai not interested. Do not recommend.

published

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.

Purchased in March 2010.

Hot Sensor Lead

published

The Hot Sensor Lead (20m) 31002715 has deteriorated after 5 years from the heat of the collector panels.
The 20m lead that is supplied by Rinnai is not heat rated. This is Speaker cable and not suitable for Hot Temp Probes. Silicone coated wire should be for the first meter then speaker cable (fig 8) will be fine.
There is no information in installation manual regarding the specs that the hot temp probe requires. I would like this so i can purchase a non generic brand.

Rinnai Equinox Hot Water SS330H2EXT

published

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.

Purchased in August 2013 for $6,000.00.

Unreliable not fit for purpose

published

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.

Purchased in September 2015 for $4,918.00.

Don't Buy... Will not buy again. Pump Failure, Frost Valves Constantly leaking

published

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.

Purchased in April 2017.

Reported pump 3 times in last year - it still whines all night!!

published

I’ve reported that the pump on our Sunmaster 26 has been running all night 3 times since we moved into our new house 18 months ago. Rinnai tell me there’s nothing wrong when there clearly is. The pump whines all night. And you can hear it from our bedroom upstairs. It’s infuriating! Our guest room is downstairs on the adjoining wall and guests complain about the noise too. I do not recommend this system at all!!!!!!

I also fail to understand why the pump runs in the middle of the night. The electricity bill probably negates the benefit of having the panel in the first place.

Rinnai please take this seriously for once and do something about it!!

Not designed for the intended purpose - Split Solar Hot Water Pannel

published

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.

Terrible

published

Panel exploded first time with frost. Could not get through to Rinnai for 4 days as their phones ring out. Then Rinnai tell me it is my fault for calling an independent plumber and paid the plumber. I am very ill and could not wait nearly a week just to get through to Rinnai and ask them to send a plumber to bypass the solar panel. 3 months later am s waiting for a panel Rinnai. Have asked Rinnai to upgrade me to evac tubes but again they are not talking to me. Perhaps I am too polite to them. Do not buy Rinnai

Good system if installed properly

published

Hot water system works flawlessly once installation issue rectified. Temperature sensor wasn't installed properly and the pump ran all night. Once this was fixed it works great. Use very little gas boosting in summer. Always have hot water available.

After 9 years a record frost resulted in one of the panels leaking. I would have thought it's frost protected, so a plumber will have to come and check it. Hence only 4 stars. But overall, happy with the system.

Questions & Answers

Nick.Fasked

I have a Rinnai Sunmaster Flat Plate system installed in 1999.
What is the life expectancy of this system

3 answers
Rinnai
Rinnai A.Rinnai

Hi Nick.F,

Thanks for the question, in 1999 when your unit was installed Rinnai offered a 5 year warranty on the Sunmaster tank. However, Rinnai Australia are committed to continuous improvement and through innovation have enhanced the efficiency of the Sunmaster Flat Plate System which has sanctioned an extension of the warranty from 5 to 10 years on the Sunmaster tank.

If you are having trouble with your unit we would recommend booking a service call. Please refer to our website with the following link https://www.rinnai.com.au/support-resources/online-service-booking.

Thanks,
Rinnai Australia

That does not really answer my question!
The unit is currently working fine,what I am asking is how long would you expect the unit to last! Ie life expectancy.

Rinnai
Rinnai A.Rinnai

Hi Nick.F,

We cannot provide an exact age for life expectancy, due to a number of factors. Actual life can be impacted by water quality, usage and improper maintenance.

It is recommended that our customers regularly service their products to ensure optimal operation.

If you would like to organise a general service, please refer to our website with the following link:

Please let us know if there is anything else we can help you with.

Thanks,
Rinnai Australia

Good Morning, we had this unit installed in our new build by our plumber in July last year (2018). Our gas bill is astronimcal all year round, $700 after discount during winter and around $400 during summer when the Hydronic isnt running. Is this normal as the only other gas device we use during summer would be the cooktop two or three nights a week? We have noticed the instantaneous running a lot,even during summer.
