Climate zone

Electricity pricec/kWh

Energy rating (cooling): 3.5; Heating: 2
Annual electricity use: 2,208 kWh; 267 cooling + 1,941 heating
Estimated running cost: $729 / year; $61 / month · $7,286 over 10 years
Capacity: 5.2 kW cooling; 5.6 kW heating

3% more electricity than the median of 236 comparable 5 kW reverse cycle split system registrations (2,154 kWh a year) in the cold zone. Uses less than 41% of them.

Across all 3,611 air conditioner registrations sold in Australia, it uses less than 73% (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.

Gree running cost by climate zone
