Since having the Rinnai Infinity 12 installed at my apartment including wireless controllers, I have had endless temperature controlled water that… Read more

never runs out or varies in temperature in the shower which I struggled with prior to installing the Rinnai. The wireless controller is easy to adjust temperature and responds very quickly. Overall super happy with the unit.

Upgraded to the larger unit – Have not had the best experience so far. (3 month old tank) Day two following tank installation, no hot water. The pilot light has gone out. Ok easy… Read more

to relight. A few days later, no hot water again. Plumber came back had a look adjusted something? And said should be all fine. Two days later no hot water. This continues to happen. Plumber contacts Rinnai on my behalf. Rinnai send different plumber out.what I think is the Main gas pressure regulator unit is replaced. A couple of days later no hot water again. happens at least twice more before Another visit, and I think they replaced the same part once more. Well this seems to have solved the pilot light issue. Unfortunately not the amount of water supplied. Plumber said this unit would provide same volume of hot water as the old unit it replaced due to improved heating technology.. 200+ litres an hour heating, @50l a shower you won't run out. (Family of 4) ok why not store less water if it can reheat much faster. Well, maybe that wasn't quite an accurate claim. Water runs out during third shower. Pretty disappointing. Not like you can just decide to go get a bigger one, not cheap throw away item. I don't know if the gas pressure was reduced to solve the pilot issue? As it takes a couple of hours to heat the tank water back up. Bit shy of 209l per hour as per product claims. Granted the water is nice and hot before it runs out. For family of four, this 135l tank does not seem to be up to the task.

Update Nov Rinnai offered replacement. I paid to upgrade size to 175 l..( The diff in price between the 2 sizes was more than if bought through retailer which was surprising) after two weeks of no further contact, I contacted Rinnai for update. Seems my case manager is MIA?? and a new person took over. Well she was very helpful. And I am not being sarcastic. After another couple of weeks [Name Removed] advised me there would be a delay. Appears the burner may have been less than perfect in these units. so there was going to be a delay in supply of tank with the new model burner. It's been a couple of weeks with the new tank all seems to be good. Upgrade rating to 4 stars as the larger tank is working as it should. As far as service goes, Rinnai were good at having the original unit serviced and offering to replace my original unit. Thanks [Name Removed] for cleaning up after the original case manager went MIA.

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.

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.
