How efficient is it for its size?

kWh per year. Bar: the middle 80% of 52 comparable 300โ€“399 L fridge without a separate freezer registrations. Dot: this model (below the median). Hover or tab to a mark for its value.

Cohort: every currently registered 300โ€“399 L fridge without a separate 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.
