11% less electricity than the median of 122 comparable 10 kW reverse cycle split system registrations (2,236 kWh a year) in the mixed zone. Uses less than 79% of them.
Across all 3,680 air conditioner registrations sold in Australia, it uses less than 50% (this compares very different sizes, so the cohort figure above is the useful one).
Annual kWh is the government label figure for a residential user in the mixed zone (Richmond NSW climate: Sydney, Melbourne, Adelaide, Perth). Mixed climate zone shown by default (Sydney, Melbourne, Adelaide, Perth); switch to cold or hot. Cost = kWh × 32c/kWh in AUD; change the price above to your tariff.
