Climate zone

Electricity pricec/kWh

Energy rating (cooling): 3.5; Heating: 2
Annual electricity use: 2,782 kWh; 327 cooling + 2,455 heating
Estimated running cost: $918 / year; $77 / month · $9,181 over 10 years
Capacity: 6.3 kW cooling; 7.4 kW heating

2% 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 36% of them.

Across all 3,612 air conditioner registrations sold in Australia, it uses less than 65% (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.
