Energy Efficient Heat Pump Design

The Dux Ecosmart 285L Heat Pump is designed to use heat from the surrounding air to heat water more efficiently than a standard electric storage water heater.

Heat pump technology works by absorbing free ambient heat energy from the air and transferring it into the stored water. This can help reduce energy use and running costs when the system is correctly selected, installed and used under suitable tariff and household conditions.

The 285L model is listed with a COP of 4.63, meaning it can produce more heat output than the electrical energy it consumes under the stated test conditions.

Smart Wi-Fi Control

The Dux Ecosmart 285L includes a Wi-Fi enabled touchscreen controller and can be controlled through the Smart Life app when connected to the internet.

The app and controller allow users to view system status, check stored water temperature, select operating modes, use boost functions, schedule heating times and help align operation with time-of-use tariffs or excess solar PV generation where suitable.

Australian Designed and Manufactured

The Dux Ecosmart heat pump range is designed and manufactured in Australia for Australian homes and conditions.

The 285L model uses R290 compressor technology, electronic expansion control valves, anti-corrosive coatings, UV stable polymers and fire retardant materials.
