3.9 kW cooling

10% more electricity than the median of 8 comparable 3.5 kW cooling only window / wall registrations (275 kWh a year) in the cold zone. Uses less than 38% of them.

Across all 3,611 air conditioner registrations sold in Australia, it uses less than 97% (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 457$151$1,508
Hot zone 1,363$450$4,498

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
