aluminium cover to protect and secure both ends. No other problems for 18 years however so still happy with the unit. Lots of cheap hot water.

Brought Tank 11 years ago and the first stainless steel leaked brand new. After several phone calls and many months the tank was replaced. The… Read more

replacement tank got to just out its ten year warranty and it started leaking badly. Rusting my steel roof. I requested Rinnai if they would honour the warranty as the original tank was replaced as faulty new. They declined. I do not recommend these tanks. I have installed a Aquatech Heat pump system instead and very happy with their service.

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… Read more

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 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.

All it is up to you – I just tell what I experienced with Rinnai 315 litre WM (315 litre 30 Tube Stainless Steel electric boost) solar hot water system. It is up to you to… Read more

decide whether it good for you or not.

I got Rinnai 315 litre WM (315 litre 30 Tube Stainless Steel electric boost) solar hot water system installed in June 2017 and it looked good at start. Less than one year, two tubes were damaged and they got replace without any cost to me. After 5 years, it could be earlier, I found out the solar panel on the roof were wrecked. It seem the pumper had not been working for a while but there was no indication anywhere except climbing up to the roof and check.

Waiting an authorised plumber to come for around 10 days. Less than 10 minutes checking. Here is the official charge:

$225.01 Checked over Rinnai solar hot water . Found manifold is faulty possibly caused due to sensor wire being broken. Quote: to supply and install new manifold, tubes and sensor wire with conduit $2900 installed.

After several weeks later, (affected by COVID). the labour cost of the panel replacement:

Replaced manifold, 30tubes and sensor wire under warranty. Tested and all working well. $567.95 labour.

Just hope it would last for 10 years.

Here is the charge details:

Rinnai Solar Hotwater model SE315AM 36 Defective – After moving in to my newly built home on 5 April 2023 I have had continuous issues with this RINNAI Solar Hotwater system, builder Hudson Homes has… Read more

had plumbers back several times over the last 3 months and no one has been able to fix the issue as the parts sent each time don't work/ defective ( complete duds) .I have been told to just leave the Electric Booster Switch turn on, that means I am constantly using my own electricity to heat this Rinnai Solar Hotwater System model SE315AM 36 everyday which is very expensive as builder installed a demand feed metre on the property. I paid thousands of $ to have Solar Hotwater only to be paying a electricity company to heat defective solar system. No one wants to take responsibility for this and I am left without what I paid for( a decent working Hotwater system) This is affecting my physical,emotional and mental health.
