59% less electricity than the median of 42 comparable 50 kW reverse cycle multi-split / vrf registrations (13,803 kWh a year) in the mixed zone. Uses less than 88% of them.

Across all 3,680 air conditioner registrations sold in Australia, it uses less than 15% (this compares very different sizes, so the cohort figure above is the useful one).

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.
