We love our new heat pump! We’re a family of two and we never run out of water, in fact it’s hotter and lasts longer than our gas system. Thank you Aquatech! Show details
The unit works really well. Always have hot water. It’s easy to set the timer on the unit itself (haven’t tried the wifi connection/app). You can hear it inside in the room (it’s installed next to a window) but it’s not too loud to be annoying. There were some scratches and dents after install - most probably the installers rather than the product but l’ll never know. Otherwise would have given 5 stars. Show details

It’s great. Not very noisy. Saves energy and no more gas bill. Love it!
Help to save energy and bill, happy with it! The installation went smooth, great job. Show details
It's been great. I am so grateful to this heat pump. And the helpline was very helpful too. Thank you Aquatech Team! Show details
Works well,looking forward to power savings,great service,looking forward to a hot shower
The Aquatech Rapid X6 has been great since installation at the start of June 2026, replacing an older gas hot water storage unit. Installation was smooth by Want a Heat Pump and the hot water has been running well with no issues. Currently running the settings as it was set up (to heat when it drops to 50), which sometimes means the unit runs in… Read more
the evening when we can just hear it. We will investigate the fan modes to see if this nose could be lowered further, but it's already a quiet motor in a city suburb. Household of 2, haven't run out of hot water at all, and the temperature has not fluctuated. Love the option to heat during free electricity or sunlight hours when we switch plans or have solar installed to help further our efficiency. Like the ability to control from the unit or via an app. As another review notes, sometimes rain gets in the side of the unit and can be seen but this hasn't caused any issues. Too early to comment on long term performance, but hoping this unit continues to run smoothly into the future!
Happy with the unit. Chose this one as it's able to be monitored and controlled with Tuya / Home Assistant, and has the powered anode for less maintenance (with an additional backup). Being the lowest cost heat pump in this capacity range is just a bonus, not the key criterion. Noise is acceptable out of the box, but I did change the settings to… Read more
reduce fan speed and now it's barely audible.
Some feedback for improvement: - WiFi is tricky to reset if you change network name or it failed to connect the first time. I'm sure their support would help if contacted, but this procedure should really be added to the manual. Someone posted a video via Whirlpool that showed how to do it. - My unit arrived with a small cosmetic dent where the power plug was pressed against the unit in shipping, the factory packaging design / QC may need a look. My installer handled this well, brought it to my attention proactively and offered to either arrange a replacement unit, or to knock a bit off the cost on the spot.
Installed by Hotwater.com.au. Great experience with them, good communication.
Easy to setup, low consumption and works really well with our smart home and solar storage systems. Show details
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
Easy installation and great value for money, would highly recommend this product Show details
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.
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
I've decided to choose Aquatech Rapid/X6 after comparing similar products on the market, based on the actual needs of my house. I like the metal cover of the appliance and the its use of a current anode. It should last longer than some competitors. Hot water system is an important appliance that we don't have to have it replaced and broken down… Read more
easily.
I'm not sure about the wirings being next to the compressor, because I saw some water inside. I am a little worried about the rain, because the appliance is placed outside. Hopefully it'll be fine, since it's supposed to be an outside appliance. Despite Aquatech has a good reputation, I had some trouble when I tried to register for the warranty. There wasn't a link in their website/manual, where I can go and register my appliance. I emailed them, but didn't have their reply. I tried to call them but had a little trouble calling their 1300 no. The system asked me to press either 1,2,3 for different services, but it said there was not such an option after selecting all of them. I've tried twice, but the system still said no such options except for 9-listen to the options again. The good thing was I was allowed to leave a message and their call centre rang me back pretty soon. They helped me with my questions and emailed me the links.
I would have given a 5 stars rating if the process was smoother. I will keep an eye on the machine and give a follow-up review later. Hopefully, it'll be a reliable and efficient heat pump that customers can trust. Hope my experience will help the company improve mire and the potential customers when it's time for them to choose a reliable heat pump hot water system.
I'm really happy with my Aquatech heat pump. It was installed in mid December 2025 by Powrhouse. It replaced an old style gas HWS which was on its last legs. The unit provides plenty of water for me and I've set it to heat daily at 12 noon to maximise my solar output. This way I'm getting practically free hot water. The unit is relatively… Read more
quiet although I can hear it running from an inside bedroom. This isn't an issue for me but could cause disturbance for light sleepers if you either have a baby or need to run overnight. I did a fair amount of research before deciding on this unit. So far it's exceeded my expectations and I would highly recommend the unit together with my installer Powrhouse

So far so good, only been in place a few hours. A… Read more
small leak has developed with the installation (attachment of a pipe) but that will was rectified very promptly. 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 (remember it is Summer). 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 during Summer). 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

Installed two months ago. I wasn’t sure if it would provide instant hot water like my previous gas system, but so far it’s been great — consistent hot water and even hotter than before (on standard mode). The only downside is the Tuya app — it’s… Read more
not very user-friendly. You really need to follow the manual step-by-step to connect it to Wi-Fi. After recently resetting my home Wi-Fi, I haven’t been able to reconnect the heat pump to the app, and I’m not sure how to fix it. Thankfully, adjusting the temperature and timers directly on the heat pump monitor is still easy to do.
It would be helpful to have a more detailed and comprehensive guide with recommended settings to optimize efficiency.
Follow-up · I’ve been using the unit for over a year now, and I haven’t experienced any issues with the system or Wi-Fi since my initial review. Noise has also not been an issue, as the unit is installed outside the house and is barely audible, even when running at night. Unfortunately, I can’t comment much on hot water recovery. However, for a small… Read more

In-depth reviews
Very pleased with my Aquatech Rapid X6 unit after a few months of usage, which was installed as an emergency after my old gas storage hot water died. With government rebates it ended up being cheaper to replace with an electric heat pump than with another gas unit. I had mine installed by Powrhouse in Melbourne as they provided the most… Read more
competitive quote. Thankfully their service was great too. My only criticism of the unit is that it runs much louder than the gas unit it replaced, but I suppose this is true of all electric heat pumps so it is not necessarily a criticism of the Rapid X6 unit itself. This is mitigated somewhat as I recently installed the Tuya app on my phone and now have the unit running on an automatic timer between 11am and 3pm daily, which provides adequate hot water to our 2-person household over 24 hours. Hopefully will have many years of trouble free usage, however if not the Aquatech warranty looks fairly decent compared to other brands. Will report back if I have any issues.

We had the Aquatech Rapid X6 210L Heat Pump Hot Water System installed in March/April 2026, replacing our ageing Rheem solar hot water system at our four-bedroom home in the North Richmond, NSW area. Our household consists of two adults, with family and friends visiting regularly, so our hot water demand varies. Since installation, the system has… Read more
consistently delivered reliable, plentiful hot water without any interruptions.
The Richmond Hawkesbury region experiences a wide range of temperatures, from cold winter mornings to fresh springs and very hot summers, and the Aquatech Rapid X6 has handled these seasonal changes exceptionally well. It has proven to be well suited to the local climate and has continued to perform efficiently regardless of the weather.
One of the biggest improvements we’ve noticed is the reliability. We no longer have to think about whether there will be enough hot water available, and the system quietly gets on with the job day after day.
Installation was straightforward, where the technician worked closely with the electrician in replacing our previous solar system with the heat pump was a seamless process. We were looking for an energy-efficient, dependable solution, and this system has met our expectations.
After several months of use, we’re very pleased with the Aquatech Rapid X6. For anyone considering a heat pump hot water system—particularly in Western Sydney or areas with similar climate conditions—we would confidently recommend it based on our experience.
Pros:
Reliable and consistent hot water supply Performs well through various seasons and temperatures Suitable for a four-bedroom home with variable household demand Energy-efficient replacement for an older solar hot water system Hassle-free operation since installation Overall, we’re very satisfied with our purchase and would happily recommend the Aquatech Rapid X6 210L Heat Pump Hot Water System to others looking for an efficient and dependable hot water solution.
Note: Product was purchased the Hot H2o (the hot water specialist)
We recently replaced our old electric hot water system with two Aquatech Rapid X6 heat pump units installed in series, and so far we couldn’t be happier. With a family of four and fairly high hot-water usage, I was initially concerned that moving to a heat pump system might mean running out of hot water, particularly with showers in the morning… Read more
and again at night. Having two units working together has given us plenty of hot water and a great amount of capacity and backup.
The system has been running really well since installation. The units are quiet, efficient and seem to recover quickly, and being able to schedule them around our electricity tariff and solar makes the setup even more attractive.
So far, we’re very happy with the performance and the quality of the system. It’s also reassuring knowing that if one unit ever needs attention, we still have the second unit available.
Very happy with the Aquatech X6 system so far and would definitely recommend it to anyone considering moving from a conventional electric hot water system to a heat pump.

Aquatech Rapid X6 installed a couple of months ago to replace instantaneous gas. We have solar so works well with it. So far so good, no issues. The brand is well priced and seem to be reliable too. Show details
The installation went well, despite heavy rain at one point. It fitted where the old gas heater had been, and a new electric line installed. Worked fine when switched on. I had a bit of trouble setting up the timer but was talked through the process by Powrhouse, who installed it (and a friend was also talked through this process by Aquatech, for… Read more
a different install, very helpful follow up). I've had it heating my water for almost four months now, and it's very efficient. The Victorian rebates made it a very attractive deal. I've yet to find out how well it will cope when I have guests staying, but so far it's been excellent. The water temperature is consistent and good.
Works well. Makes the same amount of noise as a small reverse cycle air conditioner. We upgraded from old storage heater and did not realise heat pumps make noise so you will have to allow for this if near a window. Show details
Negative reviews
* If you have solar, these cost nothing to run. Very efficient. * There are only three of us and if someone washes their hair we run out of water - nothing like the claim of up to 6 people. * It's far noisier than claimed (58dB vs claimed 42dB). You could not have one next to your neighbour's house, especially if it's heating at night. * I've… Read more
emailed customer support twice with questions and no response. Shocking! I was trying to change the timer and pressed the wrong button and could not change back and couldn't get assistance. Very frustrating. * The Tuya integration was easy but not 100% reliable.
Heats to a good temperature but water very inconsistent, goes from hot to cold a lot during the shower. Hard to regulate. Yet to see if it improves our energy bill Show details
We have been using the hws for 7 weeks. The unit is only servicing 2 people. So far the unit is fulfilling expectations. The water is hot and quickly available at the tap. It runs for 2.5 to 3 hrs to recover, starting at 9:0 am. On one cold morning… Read more
the unit frosted up and went into the defrost mode. Typical of heat pump and air conditioner units. My electricity bill is not due until August, so can’t comment on economy of unit. The installation process was very efficient and quick. Aquatech took care of the whole process and we only had to pay the balance. The installation was also very efficiently handled, all done in 2 hrs. Overall from beginning to end everything ran very smoothly. We were impressed.
Follow-up · The noise level is the same as the fan noise of a split air conditioner except it is outside. Not really a problem. It has performed faultlessly. Quarterly electricity bill $260. The unit runs for 2/2.5 hrs to recharge. When we get 3 hrs of electricity each day we will get hot water for free. You can adjust the timer to suit the free period.
