The maths
Where $1,624 of your price disappears
Three separate VIC incentives stack on this unit when you're replacing a electric storage. We lodge every form — you never chase paperwork or wait on a cheque.

Running costs
About $1,234 a year back in your pocket
Based on a four-person Victorian household — roughly 4,500 kWh of water heating a year at 30c/kWh. At a COP of 4.38, this unit only needs about 1,027 kWh to do the same job. Run it on the timer through the middle of the day and most of that comes off your roof, not the grid.
Got rooftop solar?
Time the heat pump to soak up your daytime output
Every kWh you self-consume is worth 30c instead of the 3c feed-in you'd get for exporting it — that's the solar saving baked into the numbers below.

Aquatech DYNAMIC/X8
A no-fuss swap that just gets on with it
Engineered by Aquatech Solar Technologies in Australia, the X-series runs R290, a GMCC Toshiba rotary compressor and a Blue Diamond enamel tank with an impressed-current anode — so there's no anode rod to swap out down the track. Fits the footprint of an electric 400L
Five controller modes
- Eco
- 60°C set · 2.50 kW/cycle
- Standard
- 60°C set · 2.50 kW/cycle
- Hybrid
- 65°C set · 3.38 kW/cycle
- Hybrid+
- 70°C set · 4.30 kW/cycle
- Element
- 70°C set · 9.99 kW/cycle
Factory default. Heat pump only, element never fires — cheapest way to run it day to day.
Higher trigger temp so a cycle is more likely to land inside your solar or off-peak window.
Heat pump to 60°C, element lifts the last 5°C. One cycle a day covers a small-to-medium house.
Stores the most hot water in a single daytime run — the pick for solar homes with big usage.
Element only. A stopgap if the heat pump needs a service — pricey to run, so don't leave it there.
R290 natural refrigerant
Global warming potential of 3, next to nothing. No synthetic gas phase-down hanging over it down the track.
Wi-Fi controller & app
Tuya-based app on the LCD controller — set modes, timers and target temp from the couch or the pub.
Impressed current anode
Non-sacrificial anode powered by the unit, so there's no anode rod to replace every few years. Handles soft and hard water.
Straight electric swap
The X6 drops into an electric 250L footprint and the X8 into a 400L — usually no new slab, no re-plumbing gymnastics.
Built-in solar timers
Timer windows default to 9am–6pm so the unit heats on your rooftop solar instead of buying peak power.
1800 W standby element
If the compressor ever plays up, the element keeps hot water coming until a tech gets out to you.
Performance by air temperature (wet bulb)
| Air temp | COP | Capacity | L/hr | Full recovery |
|---|---|---|---|---|
| 0°C | 2.5 | 1500 W | 30 L | 8 hr 40 min |
| 7.5°C | 3.5 | 2125 W | 45 L | 5 hr 55 min |
| 15°C | 4.38 | 2950 W | 62 L | 4 hr 15 min |
| 20°C | 5.09 | 3450 W | 73 L | 3 hr 35 min |
Manufacturer figures for a 15°C to 55°C temperature rise. Melbourne sits around the 7.5–15°C wet bulb band most of the year.
