25% less electricity than the median of 42 comparable 50 kW reverse cycle multi-split / vrf registrations (27,808 kWh a year) in the cold zone. Uses less than 76% of them.

Across all 3,611 air conditioner registrations sold in Australia, it uses less than 6% (this compares very different sizes, so the cohort figure above is the useful one).
