3% more electricity than the median of 30 comparable 20 kW reverse cycle multi-split / vrf registrations (5,202 kWh a year) in the mixed zone. Uses less than 33% of them.

Across all 3,680 air conditioner registrations sold in Australia, it uses less than 16% (this compares very different sizes, so the cohort figure above is the useful one).
