Best Electric Hot Water Storage Systems

I wanted to replace my gas hot water system and chose the Aquatech Dynamic X8 and Powrhouse after reading ProductReviewer. Rob and Tayla from… Read more

Powrhouse responded to my queries promptly and answered all my questions. Their quote was very competitive, and it included foil insulation on all heated pipes as requested. The installer, Michael, turned up on time and completed the replacement and commissioning within a few hours. We are a four-person family, and the hot water output is plenty in this Victorian winter. Fan noise is not an issue, even though the heat pump is located close to our master bedroom window, as we have double-glazed windows. It has been about three weeks, and the system is humming along perfectly.

couldn't be happier with its performance. Energy Savings: It is extremely energy-efficient. We’ve noticed a visible drop in our electricity bills compared to our old system. Performance: The water stays consistently hot and recovers quickly, easily meeting all our daily household needs. Ease of Use: The display panel is intuitive and easy to operate. Build Quality: Very sturdy, quiet during operation, and reliable overall. Highly recommend this heat pump to anyone looking to upgrade to a more sustainable and cost-effective hot water system!

Very happy with the Haier 250L Heat Pump Water Heater. It provides plenty of hot water for our family of four, operates quietly, and is easy to use.… Read more

We've also noticed lower energy usage compared to our old electric system. A reliable and efficient upgrade that we'd definitely recommend.

I cannot really overstate just how poorly this product has performed since we purchased it around 3 years ago. Here in S.E Queensland, throughout… Read more

most of the year when its above 30deg it works ok. Not that you really need much hot water during those 6 months of the year. Around mid may every single year. Every morning I hear "There is no hot water again". Every night "There is no hot water again" From my wife and two young kids.

For all the emails and phone calls I have made to try and rectify the problem. The only attempt to do so was to send a plumber out to reset some thermostatic something or rather in the software which did nothing at all.

The only way I have to ensure there is any hot water, is to go out twice a day and make sure it is forced into the on position in either hybrid or hybrid 1 mode.

The 15 year old Saxon this unit replaced probably didnt even get looked at twice in 15 years. Yet here I am baby sitting this POS appliance twice every single day to ensure the missus and kids can have a hot shower when they want one.

All these pics are after the system has run all day long consuming between 6-10kw/h. Considering the old system used around 9kwh per day and we were told this new system would be around 2.5kwh.....

The company that did the installation did a stellar job I might add, Could not fault their workmanship and they tried to assist as much as they could when we started having issues. But Im not going to continue wasting their time trying to rectify an issue with the product itself. The only real option we have going forward is to move to an IStore or go back to a traditional HWS.

have long warranties.

We purchased thesystem with the 315 litre stainless steel tank, which had a longer warranty. We have been using the system for approx 2years, and have had no problems at all. The pump runs quietly and churns out lots of hot water.

We have a family of 5 using the system, and have never run out of hot water.

I recommend the system strongly. 5 STARS !

If I could give a zero I would!!! they don’t call back or even reply we have had the machine broken and won’t give us a day to repair ‍ not hot water… Read more

Absolute piece of junk lasted one year says 7 year warranty which is not worth anything as the company has gone bust do not buy or you will regret it Show details

You're Rolling the Dice Here – I've seen a lot of these units (very popular) and the design and layout is very good - simple and elegant. The problem is the manufacture quality,… Read more

which Rheem don't seem to manage well. On mine the welding on the heater flange is VERY poor, causing it to fail and leak just on the 7 year warranty (I don't think 7 years is awesome for a tank with wires connected to it - I've had gas ones that have done 4 times that). So it's not inherently terrible - if you get one that was made by the good welder it would be great, but how would you know?

Really happy with our Envirosun heat pump HP plus 200 L Supplied from URECO solar & Hot Water. The team there were great and really helpful. Have… Read more

definitely noticed a drop in the electricity usage. Don’t use the app, nor have I changed the original settings as everything is working great and waster is very hot

The Haier Heat Pump heat the water to 55 degrees with its compressor in a very effective way. It consumes much lesser energy than by my old water boiler. Besides, I can use its ECO mode to set the preferred time of operations. Good value for money! Show details

Great most of the time (but some quality control issues) – This heat pump water heater works well when it works but there are clearly quality control issues which affect the operation of the unit in the… Read more

Australian environment. This unit has failed twice - the first within the warranty period (a faulty seal and heating element) and the second just outside (but still covered by consumer law) being a faulty sensor.

The good news is the service department is responsive and they have a local plumber who can get to the unit quickly. But make sure you have those contact details handy. The first time this unit failed, it took three days for my plumber and the plumbing wholesaler to track down how to get repairs under way.

Note that my unit is now five years old. I hope that the current generation has addressed the quality issues.

Excellent water heater!!! – Hot water anytime, no noise at all, highly recommended for families. Show details

efforts, we have never run out of hot water yet! Our solar system consists of 42 panels and 2 lithium batteries, and even on dreary old days it keeps up with the system well. My hair super light blond hair showed some copper deposits from the water, so I contacted Reece about that. They put me in contact with their water specialist who called me straight away, asked all the right questions and came up with a great plan for me straight away. Super happy with the service and the system!

anode. I called the Rinnai service line as the tank is under warranty. Unfortunately the warranty is worthless. The customer service from Rinnai is absolutely terrible, they have zero interest in helping, nothing but massive charges to even have someone come out to inspect. Buyer beware.

reliability, but unfortunately that has not been my experience.

After looking into the issue, I have found that many other customers have reported premature component failures as well. A hot water system is a significant investment, and I would expect it to last far longer than four years before experiencing major problems.

Rheem has built its brand on quality, but based on my experience, the product has fallen well short of those expectations. I hope Rheem takes these concerns seriously and improves the reliability of its products moving forward.

Update 10/06/2026:

I contacted your Customer Service team last Friday regarding my hot water system issue. During the conversation, I was advised that the call-out fee for a Rheem service technician would be approximately $300, which did not include any further investigation, labour, or replacement parts. As my hot water system is only four years old and only the cylinder remains under warranty, I would have been required to cover these additional costs myself. Unfortunately, this was beyond my budget, and I had no option but to decline the service.

As a result, I engaged a local plumber who was able to restore the hot water system and get it operating again. However, he was unable to identify the underlying cause of the fault, explaining that his investigation was limited to the scope of his expertise and the information available at the time.

In the meantime, I have also raised my concerns through ProductReview. Unfortunately, the outcome remains unchanged: the costs associated with having the unit investigated by Rheem are significant, cannot be determined in advance, and ultimately fall entirely on the customer. It appears that Rheem accepts no responsibility beyond the two-year warranty period for the components most likely to fail.

The hot water system is only four years old, and the need for a detailed investigation to determine the cause of the failure raises serious concerns about its reliability. A reasonable consumer would expect a quality hot water system to provide many more years of dependable service before experiencing a significant fault of this nature.

It is therefore extremely disappointing that a product marketed as a quality, reliable system has failed so prematurely, while the customer is left to bear the cost and uncertainty of diagnosing the problem. My experience has left me with very little confidence in the durability of Rheem products or in the level of support provided once the initial warranty period has expired.

Had this smart system installed almost 2yrs now. App has worked flawlessly for us (Rural using Starlink 3). I initially set this to an hour in the… Read more

morning to heat and an hour in the evening before we normally have showers. Rest of the day we dont need hot water do it dosnt need to work.

Found out after 6months of use that it draws 3kw an hour in the antibacterial cycle once a week if settings are below 62 degrees celcius to prevent salmonella etc. Ok, fair enough we are on tank water so that is not a bad thing. Bad thing was it almost always tended to start thus cycle for up to 3hrs using 3kw an hour during peak time at night. We have a 15kw solar setup initially making on average 80kw a day, but with no way to run this antibacterial setting during the day when we are making 13+ kw an hour was not saving us cash. Instead it almost always started at the peak hour time.

Read about the non negotiable setting time bypass if we set the heater temp up to 65C, that it wont run the antibacterial cycle weekly. But it still does run the cycle monthly.

Fair enough, but it is still running this cycle anywhere from late afternoon to middle of the night. Now we have had a 50kwh battery installed this means the thermann is robbing us of around 9kw of battery 95 percent of the time when the sun has gone out with no way to control this.

This has irked me now to write this, as we are now trying to live off grid. With winter innthe bush a heater is necessary using quite abit of battery. One EV car & cooking etc at night runs the battery fairly low as it is, let alone a hotwater heater with a mind of its own robbing us of that extra 9kw of battery leaving us with bugger all to warm the house up in the frosty mornings.

So does this heater work? YES

Is this heater app adjustable? YES

Does this heater allow you to run that all important antibacterial cycle when the sun is in full bloom? NO.

Bad design from something as simple as an app option to do this.

I still cant figure out why it only runs this cycle mostly after the sun has gone out. If there is a powercut, the thermann will be the first thing to be switched off at the meter box as we dont need something stealing our power when we need it most without our permission.

Thermann fix this flaw please, and i’ll give you the 5 stars. Otherwise we wont be going with another one with such a bad energy wasting flaw you cannot control.

Please avoid Quantum energy heat pumps - Bought the 270L hot water heat pump in June 2022 to replace a really old solar system. It was working well… Read more

for 3.5 years (until Jan 2026) when the compressor failed. Email Quantum and was received with their standard reply: 2 year warranty on electrical and compressor part, 5 year on tank. The challenged reply remained unanswered (terrible service). Just had the compressor changed for half the price of a new hot water heat pump system. I hope I won't regret this decision. One advice: stay away from Quantum Energy. Even the plumber who installed it said he has now learned the lesson with this company.
