3% less electricity than the median of 18 comparable 12.5 kW reverse cycle multi-split / vrf registrations (2,835 kWh a year) in the mixed zone. Uses less than 50% of them.

Across all 3,681 air conditioner registrations sold in Australia, it uses less than 39% (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 Γ— 32c/kWh in AUD; change the price above to your tariff.
