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!
