About the same electricity as the median of 146 comparable 12.5 kW reverse cycle ducted split system registrations (6,125 kWh a year) in the cold zone. Uses less than 50% of them.

Across all 3,611 air conditioner registrations sold in Australia, it uses less than 30% (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.

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

Same configuration and type, cooling capacity within 12% of 12.5 kW, at least 3% lower annual kWh in the cold zone.
