Tim's Aquatech Solar Technologies Hot Water Heat Pumps Review & Verdict

Tim Johnston covers hot water heat pumps and air conditioning for SolarQuotes.

Aquatech heat pumps are among the best value heat pumps in the market. They are affordable, low maintenance, quiet, come with a strong warranty and have a long track record stretching back to 2011.

Aquatech Solar Technologies Hot Water Heat Pumps: Pros & Cons

  • Affordable, but good quality.
  • Comparatively quiet.
  • Solar friendly.
  • Mid-market leading warranty of up to 7 years on parts and labour
  • Low maintenance.
  • I receive mixed reviews about the app and wifi connectivity. Customers with a need for remote operation through an app should perhaps consider alternatives.

Company Information

The company doesn't reveal much about itself or the firm's history on its website. Aquatech operates under both the "Aquatech" and "Hydrotherm" brand. Aquatech heat pumps are manufactured in China.

Aquatech Heat Pump Systems

Aquatech offers all-in-one heat pump hot water systems, meaning the tank and pump are combined in a single unit. Aquatech systems are among the quieter models we have listed on the SolarQuotes heat pump comparison table (but not the quietest). 

All its systems are accompanied smart-home app, which can be used to monitor and control operations.

Aquatech has three units on the market. The RAPID/X6 with 225L of storage capacity, the DYNAMIC/X8 with 270L of capacity and the most recently launched model the Hydrotherm FUSION/X8 with 320L of capacity.

RAPID/X6

The RAPID/X6 boasts a 225L storage tank and is rated large load capable to Australian Standard AS/NZS 4234. Aquatech says it offers enough hot water capacity for a six-person home, but take that with a grain of salt - the Rapid X6 is ideal for a 1-3 person home. 

I have a RAPID/X6 installed in my place providing hot water for my family of four: my wife (who loves a long shower), our two young daughters (who share a bath together) and me (I'm pretty quick). We probably should have gone for the larger DYNAMIC/X8 but I wanted to be a guinea pig to see if the 225L of hot water would be enough. The verdict: it provides enough hot water in summer, but sometimes the last shower runs a little lukewarm in winter (this is due to the colder winter temperatures cooling the hot water quicker).

The RAPID/X6 has an annual Coefficient Of Performance (COP) rating of 4.15.

The RAPID/X6 offers multiple heating modes, integrated timers to optimise electricity tariffs or for use with your solar power system, and wifi connectivity for monitoring.

Aquatech claims the RAPID/X6 has twice the industry standard for thickness and coatings for the tank, a galvanised casing, a 900W Toshiba compressor, microchannel heat exchangers and electronic expansion valves.

Its dimensions are 1580mm x 620mm and it weighs 105 kilograms empty. The RAPID/X6 uses R290 refrigerant (propane), which has low global warming potential.

While the RAPID/X6 runs on a standard 10 Amp circuit and can be plugged into an outdoor power point; some jurisdictions require hard-wiring.

DYNAMIC/X8

The DYNAMIC/X8 has a 268 litre tank and is suitable for households of 3 to 5 people. Aquatech tout the DYNAMIC/X8 as the "perfect partner" for solar power systems as the heating cycle can be adjusted to once per day during the times of the highest solar output; usually 10am to 4pm. 

Like the X6, it uses R290 refrigerant (propane), has a heavy duty tank, galvanised casing and a Toshiba compressor; with a backup element (1800W) ensuring continuous supply of hot water. It has an annual Coefficient Of Performance rating of 4.20.

The X8 is slightly taller than the X6 with a height of 1810mm, and a diameter of 620mm. The Dynamic/X8 weighs 118 kg when empty.

HYDROTHERM FUSION/X8

Aquatech launched a larger model in late 2025, the Hydrotherm FUSION/X8. The FUSION/X8 comes with 320L of storage capacity and is suitable for families of 4 to 7 people. The FUSION/X8 is a big unit! It is 2.15m tall and requires 300mm clearance above the unit for servicing, so it is not a viable option for households with low eaves. The unit has a 650mm diameter which is larger than the other Aquatech models and most heat pumps which have a 600mm diameter, so it requires a larger slab (700mm x 700mm).

Similar to the RAPID/X6 and DYNAMIC/X8, the FUSION/X8 uses propane as the refrigerant, comes with a wifi app and a backup element (1600W), a galvanised casing and smart touch controller. The DYNAMIC/X8 weighs 146 kg when empty. The FUSION/X8 is rated an annual Coefficient of Performance of 5.0. It 

Warranty Details

Aquatech offers a comprehensive 5-year warranty on the unit and labour. Aquatech offers an extra two years if customers leave a review on ProductReview within 3 months of installation. The review can be either positive or negative, although it must be said this probably skews Aquatech's reviews to the positive as most people have a good experience in the first three months. Still, customers might like the extra 2 year warranty for simply leaving a review.

If you own an Aquatech heat pump system, we'd welcome your review!

Early days but it appears better built and needs to run less than the previous system.

The Aquatech Dynamic X8 unit itself seems very flexible with the different timer options to take take advantage of solar power and off peak electricity rates which I really like. I was also surprised at how quite the unit is. The wifi connected unit also allows me to see what the water temperature is from my phone, which enabled me to easily tweak the timers to minimise heating cost but provide sufficient hot water when we need it

Though capacity should be theoretically be sufficient for a 3 person household, I need to use the hybrid mode (that boosts the temperature by 5 degrees with a resistive heater once the heat pump gets up to temperature) or the hot water in the morning is not enough for a shower. Pump is not too loud, but does run for 4-5 hours each morning. Overall satisfied with what I got for the price.

It is of course too early but . System is 270L we have 2 adults and 6 year in the morning water is not hot enough and some days just warm . That was not expected but heating time is only set to be once a day . Also labour warrant is only 2 years compared to many other 5 years hence the 3 star rating

Solar Run installed my heatpump sysyem (268l aquatec Dynamic/X8) quite efficiently. Electricians and plumbing staff worked hand in hand and got the job done in a breeze. Dilan Wijesinghe and team at Solar Run are a professional group I'll recommend to anyone.

The hot water system uses a wifi system in the Tuya network. The smart features won't work unless it can communicate to the Tuya servers (timers should still work). It occasionally drops off the wifi and needs a power cycle at the power point. The hws heat-pump 'heater' mode can't be activated when the water temp is between 55 and 60... It can only be turned on when it's below 55 degrees C, and it will automatically turn off at 60degC. This means if you heat it to 60 in the morning using solar, you can't 'top-it-up' to 60 in the mid afternoon if the temps aren't below 55.

Installed 2.5 years ago no issues at all, connected to solar panels means free hot water, only issues are connecting to app. Had to ring aquatech to reprogram settings on unit, not app. Unit came with very little drain hose, I had to purchase a drain hose myself I think it should have been supplied by installer. Discharge water should not be left to go under concrete slab. Unit is very quiet when running and good quality components. Toshiba compressor and impressed current anode means very little maintenance required.
Plenty of hot water, good pressure.
Had system installed 2.5 years does a great job at heating water, app is not easy to understand. Better instructions in manual would be helpful, had good help from aquateh setting WiFi. I'm using solar panels to run unit. I should recover installation cost very soon , I have no gas at home this alone saves $250 per year just on service charges. I now have installed a home battery my electrify cost are almost zero for the last 18 months. Did not come with long drain hose, not good
I have chosen this model due to its low noise levels and contained cost. It did not diasappoint: it is very silent and barely noticeable when on. It recharges in less than 1h with solar power. Installation was straightforward in 2 h. I am very happy with its performance and its warranty which I got extended to 7years with a Product Review post.
DYNAMIC/X8
Simply excellent in all aspects - quieter than we expected and similar to air conditioning noise levels. Excellent installation by Greenlogic who also supported us with solar and batteries.
Recharges in 2 hours in spring summer
LED controls easy to use, and only ever used on solar so no power charges
All good, but the App to operate it proved difficult to get working
I had an Aquatech Rapid X6 installed in December 2025. Very happy with the hot water and the noise level of the unit. Whilst I can hear it when operating in the closest bedroom, I have no issue with this. Great addition to go with my solar electricity.
The setting of temperatures and timing are poorly designed and non intuitive, nothing the supplier can do about that the manufacturer needs to remember that the “average joe/joan” doesn’t interact with this stuff every day, otherwise the recommended supplier provided excellent backup and the installation was very neat and timely.

Affordable. Very cheap to run. Acceptably quiet. Easily monitored and controlled with a phone app.
Installed Fusion X8 but so far hasn't been able to get it to talk to WIFI
Easily programmable and quiet operation
So far it's been great. Had a few initial issues with not having enough hot water as I worked out the timer and scheduler, according to our usage patterns. Never had any issues with the app. There is some noise from the unit but it's similar or quieter than the reverse cycle ducted 13kW system I have.

So great that I'm one step closer to getting off gas.
Installed Aquatech Rapid X6. Hot water is just about borderline sufficient for a 3 person household (in future I would go for a bigger tank). I use it in 'Hybrid' mode that heats the water up an additional 5 degrees with a resistive element after the heat pump gets the water to 60 degrees. Pump is not too loud, but noise is continuous during the 4-5 hours it takes to heat up,
The system does what it is designed to do so on that front it is excellent. The company I bought from was POWRHOUSE. The company owner went out of his way to accommodate me, the customer, and I am incredibly impressed.
There was a slight hiccup with the installation and the company owner went the extra mile to make sure this was rectified. The contractor also made sure the job was completed to our satisfaction.
Our overall experience was a company that takes pride in its customer service which is a breath of fresh air.
