Aquatech Heat Pump

We upgraded from instantaneous gas to make use of our under-utilised solar. For a family of 5 this unit is just coping after a week of use. Glad we went the larger unit. Due to having a tempering valve, there is noticeable pressure drop. There was a funny smell upon first use, but has gone away since. Even though the unit reports a temperature… Read more

below 40 deg C, there appears sufficient water for hot shower. This is anxiety inducing if your wife likes showering in lava. Also, existing kitchen sink is part of the tempering valve circuit which can be issue with oily dishes. Besides being very expensive and needing a dedicated power point, the unit is physically large in size. Time will only tell if this was the right choice for our situation, but the company is backing itself with an extra 2 years on warranty for writing this review.

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

We had our Aquatech X8 heat pump installed by Brightworks Solar, and the entire experience was seamless, efficient, and professionally managed from start to finish. Adrian was helpful and responsive throughout the process, and the installation team, Carlos and Nathan, did an outstanding job. They arrived on time, were careful, courteous and highly… Read more

professional, cleaned up thoroughly, and, after the electricians completed their work (which was also excellent), removed all packaging and rubbish. We couldn't speak more highly of the entire team. The Aquatech X8 looks great and operates very quietly. One of the standout features is the integrated timer and app, which allows us to schedule water heating to coincide with peak solar generation. This makes excellent use of our rooftop solar and helps keep our hot water costs to a minimum. The price is very competitive and with a solid warranty was the standout choice. Overall, we're extremely happy with both the Aquatech X8 and the quality of the installation. Based on our experience, we would happily recommend both the product and Brightworks Solar.

Excellent heat pump. This is now the second heat pump I’ve purchased from AquaTech. The first one lasted 13 years and I think it honestly paid for itself twice over in electricity savings in that period compared to an electric HWS. I would highly recommend. Show details

Happy with my Dynamic X8 heat pump from Aquatech. Purchased from Liam at HiTech Hotwater who was excellent and gave a competitive price. Installers were very punctual tidy and helped me set it up to my solar. The app is a bit average and disconnected when I installed a printer on my home wifi but no huge issues. Super-efficient and looks great as matches the house paint. Show details

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!

I have been very happy with the Aquatech Dynamic X8 heat pump hot water system. It operates quietly and is barely noticeable during normal operation, which is important in a residential setting. The system provides reliable hot water and has been performing well so far. The app offers basic functionality, allowing you to monitor and control the… Read more

system, although it is fairly simple and doesn't have advanced features.

Overall, it represents good value for money and I would recommend it to anyone looking for a quiet and efficient heat pump hot water system.

Summary - great pump, heats up quickly, no problems for 2-3 people normal usage in a 3 br double storey townhouse. If you are worried about running out, or have more people, consider getting a larger tank volume (this one is ~270L), or run the heat pump twice a day (easy to do, we run it once per day). Solar Quotes gave me Powrhouse as a heat… Read more

pump provider. They contacted me straight away and were very helpful in evaluating different options. Their quotes were excellent and they arranged installation VERY quickly. The installers arrived on time, were very professional and did an EXCELLENT job of installation. The unit was running within a few hours of them arriving and they removed the old system and cleaned up everything after them. The hot water was working later that night and the system has been great since. I put the mode to Hybrid+ which heats the water to 70 degC during the day when my solar is running and the it lasts 24 hours until the timer comes on again the next morning. **Update 9-Jun-2026** We have been using the unit for 1 month today and we have never had any issues with hot water not being available. Compared to our previous instantaneous gas hot water (which was about 4 years old), the heat pump actually has a higher hot water pressure at the taps, heats up quicker and is hotter, which I was pleasantly surprised with! We are 2 people in the house and we had a very tight space to fit the unit in, which is why we didn't choose the larger tank size model. We normally have 2 standard length showers each day (1 each). And use the hot water at our basins. The kitchen is the furthest point from the heat pump and so takes the longest time to heat up, which is where we use the hot water the most (after the showers) so the taps run for a bit before the water gets hot. This morning, for example, the Tuya monitoring app showed the tank temperature down to about 35 degC at 10am, which when I have the timer set for the heat pump to turn on. Even with the temp sensor reading 35 degC, the hot water is still as hot at the tap as other times of the day (the sensor is in the middle of the tank I believe). The heat pump turns on at 10am and generally takes about 45-60 minutes before the sensor reading start to increase. After that, it heats the water about 10 degC in 1 hour. Once it get to 60 degC, the compressor turns off and the element turns on and heats the tank to 70 degC (Hybrid+ mode) and it takes about 1hr 15min for it go from 60 degC to 70 degC before the element turns off. I did think it would be a good idea to add additional pipe insulation, to try and reduce the temperature loss over the day, so I add a BUNCH of insulation to the pipes, being careful to able to easily remove it to exposes the pressure relief valve and tempering valve (see the pictures). What I found after a couple of weeks, was the the additional insulation made NO DIFFERENCE at all to the heat loss - which really means that the as-installed condition is actually pretty good and it's not worth doing anything additional :) I added a graph of the Tuya app data, showing the water tank temp over day, with the last 30 days of data overlaid on each other. The thick RED line show yesterday's and today's data, which has been the lowest temp it has gotten to. We are normally 3 people in the house and the unit would cope fine with that running once per day I think, but if you are worried with 3/4 or more, you could always set the unit to run a second time in the evening to heat the tank up again and in only takes a couple of hours to do so.

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

I am happy with it. Good control of water heater with Tuya app and I programmed it to run it from 10-3:30 pm. Show details

Installation was quick, easy and professionally done. The system itself is neat, surprisingly quiet and a neat replacement of my old style off-peak electric heater. The Aquatech draws very little power and will be a nice match for my solar/battery system. The optional Wifi app installed easily and hooked up to the Aquatech on the first try. Being… Read more

a bit of a tech person I'm pleased at the level of information and customisation it provides. I'm a happy camper so far.

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.
