1% more electricity than the median of 39 comparable 400โ€“499 L top-mount fridge freezer registrations (329 kWh a year). It uses less than 31% of them.

Uses 20% less than the maximum allowed for its size and type under the minimum energy performance standard (413 kWh a year MEPS level).

How efficient is it for its size?

kWh per year. Bar: the middle 80% of 39 comparable 400โ€“499 L top-mount fridge freezer registrations. Dot: this model (above the median). Hover or tab to a mark for its value.

Cohort: every currently registered 400โ€“499 L top-mount fridge freezer sold in New Zealand, counted once per registration. Star ratings already account for size through the GEMS adjusted-volume formula; this comparison is in raw kWh against models a buyer would actually consider instead.
