2% less electricity than the median of 32 comparable 25 kW reverse cycle multi-split / vrf registrations (13,318 kWh a year) in the cold zone. Uses less than 53% of them.

Across all 3,612 air conditioner registrations sold in Australia, it uses less than 10% (this compares very different sizes, so the cohort figure above is the useful one).
