Best Solar Water Heaters

Great product, very efficient only runs twice a day! Looks appealing and very easy to use interface~ Show details

So it’s been just over 2 years I’ve had the iStore 270l, it’s been excellent with no issues, I’m on the bayside in SEQ, this is my 4th post about the… Read more

unit, please see my other posts about the review of this model. I called out JR Gas & Water to replace the serviceable anode and PTR valve, the anode & PTR valve looked a little wear, perhaps I could of replaced it in another 6-12mths, water hardness is mid range here and shows with the wear on the anode & valve. All up about $450 service. Recommended you replace especially if water hardness in your area is mid to high range. Other than that the unit is running great with no issues.

Have had an Enviroheat 200L unit since 2021. Had no issues with reliability. The control panel is a bit dim and non-intuitive but rarely need to… Read more

use it. I have solar and run it during the day. Even with visitors it has never run cold. Would buy again.

Very loud, no connectivity, I would not recommend this to my worst enemy. I tried uploading a video of it. Just junk. Show details

Garbage on my roof – Don't go near them, instal a shonky system and then don't enable any contact, a complete scam. The system dumped all the solar heated water then… Read more

refilled the tank with peak electricity and somehow still managed to deliver only cold water for a $6k energy bill. CATASTROPHIC SCAMMERS SHOULD BE SHUT DOWN. I have a worthless heap of junk on my roof - maybe the problem could've been easily rectified - I can't afford another bill to find out. Endless phone calls and messages - I tried countless times for months, years. This was an expensive system. I would've had more hot water from a kettle. Even my skilled electrician couldn't get the junk to work. Tried a booster button and it still just dumped any warm water it heated with the peak electricity. It doesn't take much to answer a phone or a message on a website - THAT TELLS YOU EVERYTHING - THEY REALLY, TRULY DON'T GIVE A DAMM ONCE THEY HAVE YOUR MONEY.

10litres of water onto the ground every day. House foundations being damaged. Not just from condensation outlet but also from hot water outlet. When… Read more

I try to get some solution from envirosun the customer service man hung up on me as he said " I wasn't listening to him" It was very disrespectful how he spoke to me. This leaves me with no way to find if this much water loss is normal and how I am meant to redirect the water as the plumber didn't even mention this little fact. These systems are very noisy too if folk like peace. I would not recommend this product and definitely not this company.

Extremely pleased with the Thermal Ark 200 – I am extremely happy with my new hot water heat pump and the service they provided. Paul and his team were quick, friendly & done a very professional neat job. Also great support with any questions I had. I would recommend this company and product. Show details

I purchased a NeoPower ST-EL400L-O hot water system in 2018, and it has now started leaking after only 7 years. When I reached out for warranty… Read more

support, I was told the warranty was void because I hadn’t completed a 5-year service—something that was never disclosed or explained at the time of sale.

NeoPower refused to take any responsibility and offered no resolution. For a product marketed as long-lasting and reliable, this is extremely disappointing. Their warranty policy is vague and unfair, and customer service was dismissive and unhelpful.

I also visited the NeoPower website and found that all links and references to the warranty terms and conditions are not publicly accessible.

Would not recommend—look elsewhere if you want durability and support you can rely on.

Love Solahart 302L – Had the unit for few years. Solahart 492L. Just clean the panels every year that's it. Hot water all year round. Show details

Excellent system and warranty – Perfect for saving energy costs. My electricity bill dropped dramatically. Show details

18 years later – Got on the roof for an annual check and saw that both plastic ends had perished, breaking away from the metal exposing the insulation. I made a… Read more

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.

Efficient system and working well. I have used this type of system for over 13 years so was keen to replace my old one with the same system. Show details

Ordinary system. Promotes the benefits of solar, forget to tell you that outside that, the system decides when to use electric boost - which in our… Read more

case (at least in winter) seems to be around 7am and 7pm - the absolute peak power price - presumably more than offsetting all of the benefits of the solar. Just another maddening example of horrible Australian manufacturing dressed up as something else.

Limited operational lifetime of storage tank – We purchased a new 272MLV system in February 2016, comprising two 13103008 collectors and a RHEEM 270MDV36 tank. Today, there is water leaking from… Read more

the top of the tank. Our local Solahart dealer has inspected it and has written to us to say that it is "beyond repair" and needs to be replaced at a (quoted) cost - subject to the state of repair of other components to be determined at replacement.

It seems to me that a tank supplied with the system in February 2016 should last longer than 7 years before deteriorating to a state of beyond repair. The warranty period is 5 years.

I think it is fair to ask how soon are we going to have to again maintain our Solarhart solar hot system in a functional state?

The dealer's response has been to offer a 10 year warranty on the new tank for some extra $$

We would actually prefer to recover some of our original investment in the form of a warranty claim covering the part or whole cost of the replacement tank.

We would also like to have confidence that a tank designed for external application will not fail before providing a reasonable lifetime of operation.

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.

Soul destroyer product- Do not buy – The system came with the house package from MacDonald Jones Homes. Installed in near perfect conditions, no scaly water, not a corrosive area, 2… Read more

person water load but failed just after 5 years with solar controller green LED off, and red LED blinking. Electric booster was running and bills went through the roof. System is a Loline with panels on the roof, and tank on the ground. Suspect pump failure as I checked the thermal overload and power supply and all seems fine. Called Rheem call centre and absolute waste of time. They offered a technician to visit and assess the problem which will take 5 minutes on site, and 10 minutes drive each way, so a mere 30 minutes at a cost of $270. The best solar technicians in town have a callout fee (which includes 1 hr on site) for $100 and these guys charge $270 for 30 minutes without even fixing the issue. What audacity after selling me and countless others an absolute LEMON. The call centre then went on to say that after paying $270 for a quick 5 minute assessment of the problem, I will then be given a quote for the actual fix which I expect to cost 2.5 x market rate if they charge people 2.5 x market rate for a basic call out fee. So I told her that I will use the no.1 solar technician in town who charges $100 call out fee including 1 hour of work on site and any basic fixes (this is the standard nationwide anyway). I will not spend 2.5 x market cost on these soul destroying thieves who sell LEMONS that last only a few years in perfect service conditions that other products would last 20 years. At least have the decency to charge market rates for your call out fee rather than RIP OFF $270 for half the time/value compared to others. Thieves is an understatement. Once I fix through a local solar expert, I will gather full details on LEMON products DODGY parts and file a claim through the legal avenues, and also take this further through their complaints team and ombudsman. A product like this deserves a CLASS ACTION.

Hi to all definitely would not choose their hot water solar boost they are very poor quality system . I had one installed and one solar panel looks… Read more

brown and other black looks very bad for a brand new home. and have tried to get them to replace since February they have delayed me moving in by a month up until now .and have had two of these systems before and both had to be replaced one of them broke in frost and had running water on roof and other needed new electrical board which cost 900 dollars so if you have a choice I definitely would not choose that company

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.

4S136E ecosmart solar hot water system – We purchased this ecosmart ( Dux ) when there was a rebate being offered in 2012. I paid extra for the three panels and it basically provided hot… Read more

water for a family of five without need for the booster to be turned on at all unless it was a crappy winters week without much sun. Being in northern nsw there’s plenty of sun and it was a no brainer. However....... During the last five years I have put a frost valve in it every year because it leaks down the roof even in summer. All three panels have had condensation on the glass for about five years and I’m not game to disturb them in case they will all fall apart and I’ll have nothing which won’t be an issue now because the 415 litre tank has corroded and is leaking at the bottom. Our water supply is council and is tasteless and of very good quality. A new tank replacement is $3500 or a new system is $6500. With no rebate in place I’ll opt for a $1200 Rheem instant gas ( because Thermann are also made by Dux for Reece and if they can’t make a tank to last longer than 10 years their ability to make instant gas is also questionable ). So it’s cost me $6500 plus five frost valves @ $150 each for 10 years of “free” hot water. About $700 per year. Not what I’d call a good investment.

DO NOT BUY THIS UNIT!!!!! – This unit is only 2 years old and already having issues with it. Green light and red light flashing, knocking in the roof and rattle in tank when red… Read more

light is on. Avoid the Solar loline Water Heater 511161!!! Over $5000 might as well flushed my money down the toilet. Shame on you Rheem charging $200 call out fee!!!!

Only lasted for 2 years before it started costing me money for repairs – Had this 250DPM36 unit for just over 2 years. Was good until the pump which circulates the water from the hot water tank to the solar panel failed.… Read more

The pump only has a 1 year warranty, so it cost me $319 to replace the pump. There is no way I will be doing this every 2 years. If it happens again I will be considering an alternative.

UPDATE: Dux have been in contact with me. They have agreed to cover the 2nd pump under the tank warranty, if it fails again. I do still however have to outlay the $319 now. They did state that they have only been using this brand of pump (Grundfos) for about 2 years, so will be interesting to see how many more start failing.

I will never buy a Dux again – My Dux Sunpro 305 Solar Water Heater leaked (frost valve) on it's second, forth, sixth, eight & tenth year. Each time this happened it cost me $400… Read more

to fix, plus a large water bill. Dux was not interested in finding out why this was happening. All they cared about was if the unit was still under warranty, and were very rude. The system has just sprung a huge leak 1 month after replacing the frost valve for the 5th time.

I have had enough and are now replacing it with a different brand.
