Why Choose This System

Smart Technology, Real Savings

The Dux Ecosmart 285L uses R290 natural refrigerant and a patented dual wall heating coil to deliver up to 4× more hot water per dollar than a standard electric system. Designed and manufactured in Australia for larger families and new builds.

Cut Your Bill by Up to 71.6%

With a COP of 4.63, every $1 of electricity delivers over $4 of heating. Annual energy savings of up to 71.6% are based on Australian Government approved modelling using a medium load in Zone 3.

📱

Smart Life App Control

Monitor status, change operating modes, set timer schedules, and activate single-shot boost remotely via the Smart Life app. Settings are saved even in the event of a power outage.

🌡️

Backup Element for Low Temperatures

The 1800W backup electric element provides heating in very low ambient conditions and for single-shot boost applications, ensuring hot water is always available when the heat pump alone isn’t enough.

☀️

Solar Ready

Schedule multiple daily heating windows to align with your solar PV generation. The Smart Life app and built-in touch screen controller both allow timer programming to maximise self-consumption.
