9% less electricity than the median of 23 comparable 350โ€“499 L upright freezer registrations (339 kWh a year). It uses less than 74% of them. At 33c/kWh that is about $10 a year less than the median, $96 over 10 years.

Uses 44% less than the maximum allowed for its size and type under the minimum energy performance standard (554 kWh a year MEPS level).

How efficient is it for its size?

kWh per year. Bar: the middle 80% of 23 comparable 350โ€“499 L upright freezer registrations. Dot: this model (below the median). Hover or tab to a mark for its value.

Cohort: every currently registered 350โ€“499 L upright 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.
