Aquatech Heat Pump Hot Water Systems

Aquatech Solar Technologies (ABN 68 136 584 328) engineers the X-series here in Australia and has been shifting them through the Victorian trade for years. The line-up is deliberately simple: RAPID/X6 at 225L, DYNAMIC/X8 at 268L and the bigger FUSION/X8 at 320L.

The clever bit is the footprint. The X6 drops straight into the space an electric 250L used to sit in, and the X8 into an old 400L — so on most swaps there's no new slab, no shifting pipework halfway down the side of the house, and the sparky's job stays a 10-amp single-phase hook-up.

Underneath it's proper gear: R290 natural refrigerant, a GMCC Toshiba rotary compressor, a microchannel aluminium heat exchanger and a Blue Diamond vitreous-enamel carbon steel tank. The anode is non-sacrificial impressed current, so unlike most tanks there's no anode rod to pull and replace every few years — handy in both soft and hard water areas.

Control is through an LCD panel with Wi-Fi and the Tuya app, running five modes — Eco, Standard, Hybrid, Hybrid+ and Element — plus built-in timers that default to a 9am–6pm window so the unit heats on your rooftop solar instead of peak grid power.
