Best Electric Hot Water Storage Systems

We decided to switch to a water pump after seeking advice from our plumber to replace our broken existing system. The Aquatech Dynamic X8 was… Read more

recommended by several installers. We went for the 268L which is plenty for our 2 person household plus the occasional visitors. The wifi set up was quick and the app is very easy to navigate and use. We also called the Aquatech helpline with a question and they were very helpful.

Very happy with the EvoHeat heat pump system, performs efficiently and provides plenty of hot water for our house. Really like the timer control functions for managing our energy use through a solar/battery system Show details

We've just installed a 200ltr Haier Monoblock water heater and our daily electricity bill dropped from $21 to $14.30 overnight. Not only is it super… Read more

efficient it looks fantastic and would make the people at SpaceX jealous! We have 4 people in the house including two teenage girls who like to take long showers and it handled them both without a problem - and in the middle of a Tassie winter!

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.

32 years gas water system. I heard so many negative feedback about electric hot water. I am glad I took the chance. The heat pump runs smoothly and provides plenty of hot water constantly. It saves me a lot of money. It cost 31cents per day on average. The noise is same as running aircon. It’s sitting outside, so I don’t really hear the noise. The app is great. You can see the water tank capacity and the current temperature. Highly recommended Emerald.

Tidy quiet efficient unit : I purchased the EVO 150-E. . Delighted Show details

I don't think I could ever get excited about a heat pump :). Aether HP270 did not disappoint, unit looks sleek, very straightforward to use with the… Read more

app, and works well with consistent water temp that was set (although a bit early on from install so obviously working perfectly atm, but will defo come back if anything out of ordinary will come out). What's fab is we are now able to control and monitor heating and usage which is a game changer to save up on expensive bills :) We also observed that it retained the temp whilst very cold Melb winter nights. So glad we stumbled on previous reviews that helped us decide which product to use!

Beautiful modern unit, minimal noise, works well! Very happy with purchase. Show details

Very rude and unprofessional installer. If need to retain your brand reputation please change the installer and hire better ones. Damage the vents while installing Show details

A very disappointing experience with these hot water heaters. New build, first one lasted just over 12 months. A lot of hassling with the service… Read more

department and several weeks of delays before a new unit was installed under warranty. I had asked for my money back instead, but that apparently was not possible. Twelve months on (almost to the week) and the second unit has failed and requires replacing. My understanding is the the WWK series are discontinued and being replaced by the SPH-0 series. I asked if I could pay to have the new series installed but was told that was not possible and so now here we are waiting for a week without hot water for a discontinued hot water unit that will most likely fail again. I would never recommend Stiebel Eltron, the poor quality of the system is just one aspect, but a company culture that is not customer focussed is the real nail in the coffin.

This is an amazing heat pump hot water system. Full 320ltr capacity is more than enough for the family of 4. Efficient system and light on back pocket.

four, we run four showers back-to-back in the afternoon. Never run out of hot water. Also, our unit is very quiet and haven't noticed any temperature fluctuation. Thank you

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?

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

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

New hot water system installed 02/09/2025 and is going great so far with no issues. Recommended by plumber who has been amazing. Show details

Called customer service early in morning to request service call. They referred issue to service department to book call, however after 3 hours I had… Read more

still not heard anything from them. After a follow-up call to customer service they contacted service department to determine when service could be be arranged and was told the service could be arranged tomorrow. This was totally unacceptable as our system was not delivering hot water and no-one would be home tomorrow. Most Hot Water Service companies guarantee same day service, not to mention that Ecogenica required a $230 call out fee + GST and parts ! Needless to say I contacted a local service company and had a technician arrive within 1 hour. Very poor customer service from Ecogenica , no recommendations from me.

We are completely off grid, and this system has been brilliant so far! December marks two years in our new house, and despite my partner’s best… Read more

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.

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.

My Rheem hot water system is only 4 years old and has already stopped working. I chose Rheem because of its long-standing reputation for quality and… Read more

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.

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.
