Check the Energy Rating Label and compare the star rating and estimated annual energy use with similar-sized models. Choose an appliance that suits your household, because an oversized model can waste energy, and look for efficient settings such as eco cycles, heat-pump drying or inverter technology where relevant. Check standby power, operating costs and whether the appliance can be repaired, rather than judging by purchase price alone. For Australian product ratings and label requirements, see the official Energy Rating website and follow the manufacturer’s installation and maintenance instructions.
