Energy rating (cooling): 4; Heating: 2
Annual electricity use: 2,264 kWh; 245 cooling + 2,019 heating
Estimated running cost: $747 / year; $62 / month · $7,471 over 10 years
Capacity: 5 kW cooling; 5.8 kW heating

5% 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 31% of them.

Across all 3,611 air conditioner registrations sold in Australia, it uses less than 72% (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.
