9% more electricity than the median of 6 comparable 8 kW reverse cycle fixed registrations (3,740 kWh a year) in the cold zone. Uses less than 17% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 47% (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 cold zone (Canberra climate: Canberra, Hobart, Ballarat, alpine areas). All of New Zealand is the cold zone on the Zoned Energy Rating Label. Cost = kWh × 33c/kWh in NZD; change the price above to your tariff.
