About the same electricity as the median of 54 comparable 3.5 kW cooling only portable registrations (733 kWh a year) in the cold zone. Uses less than 35% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 92% (this compares very different sizes, so the cohort figure above is the useful one).
