Rinnai Solar Gas Boosters

Beware frost in Melbourne & how to repair/replace! – This came came installed on new two storey townhouse in Melbourne. It’s worked well for 7 years but it froze then exploded last week with subzero temps overnight, leaking water everywhere! I’ve had to divert it to instantaneous gas hot water (no tank) with an emergency roofing plumber. Unfortunately, there is limited property access so I’d need an… Read more

expensive crane to remove/replace because it weighs >100kg. Therefore, broken system will be staying on my roof indefinitely. Most (if not all) of these Rinnai 20 solar systems have broken for my neighbours. If you live in Melbourne, do your research into frost proof systems & how to replace and repair. Needing to pay a roofing plumber to inspect any issues is an added expense.

Awesome unit have had it in for 6 months now and it has not missed a beat ..!!! – Never run out of hot water which was always a problem with solar with the s26 no real issues on temp we have always got lots of hot water now, Show details ·  1

Nothing but trouble – House was built 2014 with a Rinnai solar hot water system, Easter 2017 the release Frost valve blew on solar panel, water was gushing out running down drain pipes, we didn't hear it on that side of the house until a neighbour called our attention to it, we called Rinnai Ph.no. only an answer service stating "they were closed for the Festive season… Read more

and leave a message" . We called out local plumber and he showed us how to turn off the hot system so we could flush the toilets. Rinnai fixed problem under warranty. next problem was about July 2018 when the Frost valve blew again this time also blowing the solar panel, this was replaced under warranty. Now! MON 18 Feb 2019 warm sunny weather Frost valve blew again, running all night, again alerted by neighbour, called Rinnai who sent plumber out he taped it off as informed by Rinnai because they were having so much problems with it. Plumber told us pressure pump wasn't working warranty outdated, paid $145.38. following FRI 23 Feb, hot water gushing out of boiler, plumbers out again, release valve wasn't working, out off warranty, $228. You can buy this valve for $52 less for trade, working on job was abt 30mins. Next day SAT 24th About 6pm NO HOT WATER just cold, just cold. Now have to go to sons house for showers, we are 75yrs, not able for this pressure or expense. We have got nowhere talking to Rinnai, I would NOT recommend putting in this system to anyone, it is unreliable, after service is not good. We kept getting told "These are all separate issues" that might be but it's all about the same Solar Hot Water System. It will be interesting to see what they say on Monday when we ring. Will post outcome.

Nightmare – Bought our place 2 yrs ago. Is now 5 yrs old. A month after purchase we heard water gushing but no idea where from. Never had solar before. Contacted previous owner who was also builder, who got the frost valve replaced (we were out when plumber came) Today the people behind us came around to say water was leaking from the panel again. Try getting… Read more

a plumber out at Easter to fix it. Water down the drain all for another frost valve. Yes we are near Melbourne but really. I am sure it is out of warranty now but how often does the same item need to be fixed.

Just seeking assistance for now – We had Rinnai solar 20 installed in the new home with sun master system. The trouble is if one is having a shower and someone opens another hot water tap or an outlet in side the house, the one in the shower gets cold water. I spoke to Rinnai and was told it should not happen and to get the plumber call them. The Plumber came roamed around the… Read more

house opening and shutting taps and spoke to Rinnai and left. The result is the same. No change. I have used Rinnai hot water units in Japan and they were world class. In my old house we had another brand hot water unit, served us for 10 years and never had this trouble.I thought of a better flow and agreed on Rinnai. but I regret thoroughly getting Rinnai installed now.

So I cannot promote Rinnai Products in Australia to anyone.

Never worked. Didn't honour warranty – I have a S26 Solar infinity system installed new by a builder in a new home in Melbourne in 2010. It never worked - water in gas line by a non-qualified plumber destroyed the unit. Rinnai did answer emergency line and sent a plumber out 18 hours after I called (Late Friday afternoon) - he didn't even want to come and tried to get me to wait until… Read more

Monday! I had to pay almost $800 for this emergency warranty service.

Rinnai "repaired" the gas boost has never worked right since - and they billed me to "repair" it. If it is windy, damp, cold, or humid - the gas boost will not ignite or stay lit. It sometimes take over 40 minutes of shutting the water off for 10 seconds (Rinnai's suggestion) and turning it back on until it stays hot.

Don’t buy from Rinnai if you want hot water.

3 visit by Rinnai less than 2.5 years 0ld. still not going – This is the worst product ever. My Rinnai Sunmaster 26 solar is less that 2.5 years old now but it had been visit over 3 times by Rinnai and still not going. never buy from rinnai again. they have custmer support from 9 to 5:30 mon-friday and their emergency line never answer the phone. i have left message 2 times and they never call me back.

too cold – I have a split solar water system with a gas booster. It says Rinnai 20 on the outside, whatever that means. It takes forever to get hot water out and when it comes out it's luke warm. It's never warm enough to do the dishes. Forutunately one of the bathrooms is 1 meter from the tank so water that goes there is hot enough to shower in. cold and expensive

Rinnai Solar 20 is terrible – We have Rinnai Solar 20 and hot water doesn't come out of the kitchen tap for ages...i use a container to collect the cold water until hot water comes out and i use that water for the garden. Just like Nomad40 says...the hot water isn't hot... i also can leave my hand under the running hot water and it isn't hot enough to wash my dishes...i… Read more

have to boil litres of water in the saucepan/kettle to do the dishes and the makes it an inefficient system...

we are the second people in our home and we don't have the warranty only the Rinnai handbook...we can't afford a plumber to come out...help??

Hot water takes a very long time to come through to the kitchen and the water isn't hot...have to boil water in saucepans/kettle

Terrible – Edwards roof mounted tank with electric boost is far better. Rinnai not worth the money. For the kitchen and laundry you need to have hot water when required. Nothing. The builder put it in and kept the rebate Wastes a lot of water getting the warm water. Being regulated heat in the shower the hot water shuts off for a few seconds while showering. When there is no sun the hot water is not hot. I can put my hands in it. Real hot on a hot day.
