Installation was smooth and the unit looks great. It’s still early to comment on long‑term efficiency, but so far I’m looking forward to seeing how it performs. Show details
Very good service from Green Logic Australia and the heat pump is running smoothly and quietly. It was very easy to connect the system to wifi and set up a running schedule to make the most of solar power. The water temp stayed high all night and the system only needed to turn the compressor on for about an hour this morning to get back to 60 degrees. Show details

Based on my research, this is the best value for money heat pump on the market for several reasons. - Impressed anode rather than sacrificial = less maintenance cost - Very quiet at 42 db at 1.68m - About $800 cheaper compared to comparable models like iStore - Good warranty , 5 years parts and labour. Make that 7 years if you do a review like… Read more
i'm doing now - Good Coefficient of Performance up to 5.0, iStore COP is 4 - Made in Australia, parts from china / globally sourced. - Blends in with the colour scheme of my garden. Some others like iStore would not blend in.
I went ahead with the aquatech and got pwerhouse to install it for me who gave me good service.
I've had the aquatech for about a month now and i'm impressed at how it retains heat very well even in the cold, how little electricity it uses and how it's able to handle 3 showers in a row on Wednesday nights after swimming.
The only real bad thing i can think of is the wifi connectivity. The connection is not very stable and you will often have problems connecting with your phone app to the heat pump to control the settings. Or often you turn on the app and it will give you the last log in's data rather than the current data and you need to reset the app to get the current data.
Once or twice, it has actually lost connection during the time it was scheduled to turn on and thus the heat pump didn't turn on at 10am as it was supposed to. To get around this, I've set two times for it to turn on 10am and 11am and two times for it to turn off 8pm and 9pm. In this way, if the first one fails, then the second time will hopefully kick in to save the day.
Overall, it's a very good pump and i'm loving the savings i'm getting from not having to pay for my old gas unit. Especially, now heading into the Winter!
The government rebates practically make it 50% off , so it's a great deal!

We are amazed at the small kWh this unit draws to reheat water. The Phone App monitor and controller works very well, and shows present water temperature. When combined with Amber electricity supplier, we can program our water heating at our discretion, not the electricity supplier! It a perfect partner to our 24 kWh battery. Fantastic unit, recommend it! Show details
We installed an Aquatech DYNAMIC/X8 via Same Day Hot Water Service (SDHWS) Melbourne on 05 May 2026. The unit works as it should be. I'm very happy with the unit. The price from SDHWS is the most competitive ($1400, standard installation, after rebate). The team (Shery and his team) did a fantastic job to install the unit. They followed all the… Read more
rules and compliance. They are friendly, patient to explain to you the process, and had removed all rubbish after the job. I would not hesitate to refer my friends to get the installation through them.
I can easily monitor the water temperature and control the unit remotely via the Tuya app. I can set up the time to turn on the unit whenever I need especially during the period when electricity is free or when there is plenty of solar power.
I barely can hear any noise when the unit is heating the water. It takes about 2.5 hours from 50C to 65C.
Aquatech provides up to 7 year warranty on parts and labor.
Overall, I highly recommend Aquatech DYNAMIC/X8 and the installer SDHWS in Melbourne.
Easy installation and great value for money, would highly recommend this product Show details
Have only had this system installed for one day but I am suprised that the water is so hot and through out the house as I had a solar hot water system with roof panels for 16 years and only got luke warm water near the unit.bathroom and it got colder the further it had to travel it is also so much quieter than i thought it would be and the app is… Read more
very i formative and helpful and works well to my suprise all in all an excellant choice of a heat pump
We have had the Aquatech Dynamic X8 heat pump for one week (installed in April 2026), replacing a 20+ year old thermal solar system. I like how I can set the heat pump start/stop timer, and in this cooler weather it is taking approximately 1.5 hours to heat the water to 60degC. (water inlet temperature 16degC, initial sensor temp. 52degC) The… Read more
noise when operating is noticeable but not loud. We are happy with our purchase as we now have a reliable supply of hot water.
I had to replace my 15 year old heat pump with a new one and after extensive research settled on the Aquatech Rapid X6. It is a bit smaller than my previous one but this also means I don't have to heat as much water that I very rarely use (I only ran out of hot water once with a lot of visitors in the house). Same Day Hot Water from Sydney got me… Read more
a short timeframe for the install and a very good price, also I can't praise their installer Daniel highly enough, very professional, courteous, gave me options if required and took the time to get it right. So far the heat pump works flawlessly and I like the control with the app to set the time of the heating cycle. I have a CL2 plan but took it off as I thought the controlled load would be only at night and the heat pump performs best during the day when it is warmer. I might change it back if the energy provider gives me more information when CL2 is in operation. Though the pump is not as quiet as I hoped it is manageable in my circumstances and can be stopped if required via the app.
Powrhouse installed the Aquatech Heat Pump Rapid X6 water heater in December 2025 at Doncaster, VIC 3108, and I’m extremely satisfied! It heats water quickly and maintains a consistent temperature throughout the day. The unit runs smoothly, which is a big plus, and it’s noticeably more energy-efficient than my previous system—my electricity bills… Read more
have gone down. The tank capacity is perfect for our household, providing plenty of hot water even during peak usage. Installation was smooth, and the controls are simple and intuitive. Overall, a reliable and high-quality hot water solution—highly recommend Powrhouse!
I had an Aquatech Rapid X6 heat pump installed on 20/02/2026, replacing my previous heat pump, which was only eight years old but had begun to show signs of internal rusting. The installation was excellent, organised by Tye from Same Day Hot Water Service in Melbourne, and I also received very good customer support from James at Aquatech’s Head… Read more
Office in Brisbane. It is, of course, too early to fully evaluate long term performance, but so far, the Aquatech Rapid X6 runs beautifully. I’m very happy with the hot water output as well as the low noise level of the unit. One of the key reasons I chose an Aquatech heat pump was the use of an impressed current anode to protect the tank, rather than relying solely on a sacrificial anode like many other brands. This means less maintenance and only a major service required every five years. So far, I’m very happy with the performance of the unit.
After deciding on the Dynamic X8, I contacted a couple of installers for quotations and found there was a significant price difference for the same product and I decided to go with Same Day Hot Water. My choice did not disappoint because Andrew from Same Day Hot Water did a fabulous job and even replaced a faulty power point at no additional… Read more
charge.
I’m very happy with the Aquatech Dynamic X8 heat pump so far, except for the app and Wi-Fi connection. I also found that the temperature and operation time setting procedures are not identical to those in the owner’s manual, which made it a bit frustrating to complete.
However, I didn’t bother connecting the pump to the app, as my phone already has too many apps.

After researching many different heat pump hot water brands, I finally decided to go with the Aquatech Dynamic X8 and I’m very happy with my choice.

Service to install the system and the whole experience was great. The team was friendly, professional and very efficient. The installation was completed quickly and smoothly.
Overall, I’m very happy with both the product and the service and would happily recommend them to others looking for a reliable heat pump hot water system.
Ordered it from the company Gaschill on the 23/02 and had it installed the next day, very happy with how quick they are. The installers (Liam and Jack) were very professional and communicated well with me. The installation itself was smooth and afterwards left the area very neat and tidy. The unit looks great, very happy with it. Show details
Although I expect to receive an incentive (a warranty extension) for submitting a review, to Aquatech’s credit there are no restrictions on the content — whether positive, negative or neutral. I deliberately waited nearly three months after installation (2 December 2025) before writing this review to allow sufficient time to assess performance. … Read more
### Pros ###
* I paid $1,450 after all discounts and rebates, compared to the full price of $3,780, for supply and installation of a new unit. * The system replaced an 18-year-old gas heater that was still operating reliably. However, given its age, replacement was likely inevitable and could have required an urgent action without access to rebates. * I noticed improved water flow (stronger shower pressure), although a heat pump is not expected to affect pressure. This may be coincidental or related to pipe configuration. * Hot water appears to reach outlets faster than with the previous system. So far, usage has been during summer months; performance in colder weather remains to be seen. * Since gas is now used only for cooking, my gas consumption has dropped significantly. At present, the bill largely consists of the daily supply charge. * The most significant benefit is the ability to schedule heating during peak solar generation. I set the timer to operate between 10:00 am and 4:00 pm. Once the tank reaches 60°C, the unit stops automatically. Based on summer performance since early December, I believe the system has had negligible to no impact on my electricity costs. This is largely due to solar generation; I do not expect the same outcome during winter. * We went for a slightly larger than recommended water tank capacity (X8 instead of X6) and have not run out of hot water once. * Noise levels are very low. Even in a quiet house, the unit is not noticeable. * Timer settings can be configured directly on the unit, without requiring Wi-Fi or a mobile application.
### Cons ###
* Shortly after installation, I experienced an issue connecting to the unit via the Tuya mobile app. After contacting support, it was determined that the Wi-Fi controller was faulty. On the flip side, 1) the replacement process was straightforward — the new controller was mailed to me, no questions asked and 2) the replacement process requires no technician visit. * The mobile application itself is not particularly user-friendly and can be unreliable. * The installer provided the owner’s manual and Wi-Fi setup guide, but did not offer verbal instructions. While this may not be an issue for someone comfortable with technology, less tech-savvy or elderly users may find initial setup challenging.
Overall, I am extremely satisfied with the unit’s performance to date and would recommend it based on my experience so far.
The Best supplier ever ! Friendly and helpful. And Rob, the installer Hes so passionate, clean , tidy and detailed. So happy ! Thank you Show details
Powrhouse process was smooth right up to installation of our AquaTech Dynamic X8, installers were on time, efficient, friendly and experienced, clean up after all work done. Recommend AquaTech & Powrhouse anytime, in fact 2 of my neighbors were interested after witnessing the installation, told them to contact Rob of Powrhouse. Show details
I’m very happy with this heat pump system. I can’t commebt on the customer settings available as I am happy with the default settings. But I can attest to its affordability and price point. There are many cheap heat pumps in the market which are poorly made and there are several high end systems that are rather over engineered. Aquatech seems to have found the sweet spot in the middle. Highly recommended. Show details

Installed the Aquatech X8 hot water heat pump in March. Initially set by installers on Standard settings, once I got to understand how it worked, I uppped the setting to Hybrid1. This means that a single daily heat cycle during the day when my solar… Read more
is producing is enough to provide more than enough hot water next morning for morning showers for everyone. The noise from the pump is hardly noticeable and it's using what I consider to be a negligible amount of power too. Powrhouse - my installers - were fantastic!! From initial contact through to ongoing discussions and questioning, to the final phase of quoting and installing, they were nothing short of exceptional. The onsite crew of plumbers and electrician were also top notch. Everything was done professionally, all work was performed efficiently, and everything was cleaned up and tidied up as they went. Much better than others I've had here recently for solar works. So far, I couldn't be happier with the new hot water heat pump and expecting to get years of efficient service from it. And I'm already seeing benefits in a lower gas bill having converted over from a gas storage hot water system. Highly recommend both Powrhouse and Aquatech.
Follow-up · In the couple of months of having the hot water heat pump, I am definitely pleased with my choice. Plenty of hot water and it must have pretty good insulation because it remains hot right through into the next morning. I only let it heat up during the day, utilising solar and/or battery power. I have seen a dramatic fall in my gas bill and no… Read more
Install was very professional by Powrhouse. Unit seems to do the job. Temp is quite consistent although I've found that the water temp does drop quite a bit overnight. Early days yet but time will tell. Show details
Follow-up · It’s been a couple months now since install. 1. Finding the hot water pressure considerably lower than our previous gas instant hot water unit? 2. Reheat takes a while and the water temp is no where as hot as gas! 3. Family of 3 need to reheat tank at least twice a day. 4. At this stage not sure I’ve made the right move away from gas?
So far so good, only been in place a few hours. A small leak has developed with the installation (attachment of a pipe) but that will was rectified… Read more
very promptly rectified. A shout out to Same Day Hot Water Service. It was a little louder than I expected but not too loud, definitely louder than a fridge. Looks good not that is important for a hot water system on the "dead" side of the house. The real test is how long the system lasts. I won't be able to comment on that for at least 10 years. It took 2 hours and 30 minutes before the system had completely heated the tank when the temperature outside was 23 degrees.
I have had the water heater now for two weeks. Plenty of hot water for a family of 3. I have left it on the standard heating plan. It starts heating a 10 am and the water is up to 60 degrees Celsius by 11:30 at the latest. The heater seems to have gotten a little quieter (or I have just become used to the noise) but between 10 and 12 in the morning it is not going to disturb anyone. The app is not great, but the system can be set at the heater. In all reality, do you really need an app for something as automatic as a water heater. You can check the temperature of the water on the app for peace of mind. I did this initially over the first week but after that it stops being novel and you forget about it. I have upgraded my rating to 5 stars now that it is in and going.
The company does offer a longer warranty if you post in this forum.
I will post again in 6 months (if I remember). Again, the real test is the longevity of the system which I can't comment on yet.
Follow-up · The water pressure is good. Power consumption is low, it uses about 0.7 kW for between an hour and an hour and a half (when a lot of hot water is used). I can see clearly when the heater goes on and off and how much power it consumes from my Solar Battery App. The heater works so well in conjunction with a solar battery system.
Follow-up · Now that it is getting a bit colder the heat pump runs a bit longer from 10:00 to 12:00 sometimes even 1:00 depending on the weather. Enough hot water for 2 people as it gets colder sometimes when there are three people at home the water is a little… Read more

I had two Hydrotherm heat pumps that decided to turn tail up - fortunately just before the warranty period expired. One had been playing up for a while, the other just dropped its bundle (of water) overnight. When I first searched up the contact for Hydrotherm, I was very concerned to find out they are now Aquatech. Well, frankly, that turned out… Read more
to be very fortunate. I had dealt with Hydrotherm a couple of times during the life of my systems and they weren't that helpful. Enter Aquatech who were very responsive in trying to help with the first system's issue, walking me through troubleshooting on the phone. When it turned out both systems were faulty and not recovering, they arranged a plumber (Adam) to attend and replace both units. I wasn't expecting that - I would have been happy with a repair, but it turns out they knew better and didn't try to pretend otherwise, which is refreshing. I had a bit of an issue getting things organised in the short timeframe I had - I was unaware the plumber was having to factor in a replacement, not a repair, so I was a bit annoyed at what seemed like unnecessary delay - but it was all handled with urgency and excellence in the end. Super-impressed with Aquatech's service and Adam worked tirelessly to get it done on the day. Thank you - very appreciative of coming across a business with integrity and will be keeping this mind for any future HWS needs on other properties.
Installed two days ago so this is a short term review (we also had a good installer who did a great job)... - Aquatech are offering extended warrenty for reviews but the review is unaffected by this (The standard warranty is 5 years for parts, but with this offer, you'll receive an extended 7-year parts & Labour warranty.) - Produces good… Read more
consistent hot water as expected (for 4 people)
- The wifi took 15 minutes and a number of tries to get going which was a very minor pain (you need to be on a 2.5hz and the auto selecting of my wifi was confusing it. My mesh system had a setting for creating a second network for home automation with limited features and as soon as I turned that on it worked fine).
- aesthetically unobtrusive
- Apart from the very expensive units it is one of the quietest on the market. I am glad I paid a bit more for the quiet model because they do make a bit of noise (basically like a quiet air con). Still this is a major down side of heat pump technology so worth the $200 extra I paid.
- The app is OK Tuya and offers some good basic functionality that is easy to use and a lot more complex stuff that I have not explored. I easily set up a schedule to raise the temp on the heater once a week and then level it on a cooler setting.
We recently purchased this unit. And very happy with its performance. Nice unit. With long term excellent after sales support and warranty back up, I won't be surprise if this unit will outsell more expensive unit in the market. * User manual is almost perfect (8/10). The only downside is it missed the explanation how to tell the unit to… Read more
activate the WIFI so the phone can find it. Luckily Aquatech Support help phone line is responsive and helpful. HOW TO ACTIVATE: with screen on the unit unlocked, press the "power button" and the "up" button at the same time and hold them for 3 second to turn on the WIFI. Your phone with Tuya App already installed will then find it. * Heat retention is good (8/10). * Noise level is good (8/10). Installed around 2-3 meter from our bedroom window. Barely can be heard from our bedroom. * Heating performance is good (8.5/10). Approx 10 Celsius / hour using the compressor only. * iPhone App is basic but straight forward (7.5/10). Additional feature such as following will definitely improve it: 1. Data logging and Graph will help user to fine tune the unit. I am lucky I have Enphase Enlighten App to help us to fine tune this unit. Not to start too early or too late to heat up before the next day. To give us the most headroom for the available power from Solar Panel. 2. Custom Profile such as option to run the Compressor with the help of Heating Element to quicken the process. * WIFI Connection (10/10): the manual recommends to use 2.8GHz Channel, but we use 5Ghz knowing that our Router is nearby. Connection is stable. No issue. * Power Consumption (8.5/10): the unit consumes around 0.9kW when heating.

Top notch unit. Never runs out of hot water. Household of 2-4. Those that complain of app/wifi issues - that’s likely your own wifi/connectivity issues, not a product issue. App is excellent and you can set timers and customise hours of operation to make use of free electricity timeframes and/or solar and battery use. Not too noisy, similar to an outdoor split system air conditioner unit in terms of noise.
We have just installed Aquatech Dynamic X8. This review page was very helpful in helping us decide on a suitable heat pump. Aquatech representative was very helpful in communication.

really good decision.
The plumber (Adam Taylor) in Brisbane was very quick and did a great job. Highly recommended.
First ever heat pump installed at the home, in late April 2026. Working well. Water temperature not fluctuating. Can hear the pump from inside the house but not finding this too loud or distracting.
