6% more electricity than the median of 110 comparable 6 kW reverse cycle split system registrations (2,728 kWh a year) in the cold zone. Uses less than 15% of them.

Across all 3,611 air conditioner registrations sold in Australia, it uses less than 63% (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 Γ— 33c/kWh in NZD; change the price above to your tariff.

Mixed zone 1,462$482$4,825
Hot zone 1,636$540$5,399

At 33c/kWh. Formula: cost = annual kWh Γ— price. The kWh figure is the label’s residential estimate for that zone; commercial-profile figures are in the specifications.

Heat pumps that use less electricity
