Electricity pricec/kWh

Energy rating (cooling): 4.5; Heating: 2.5
Annual electricity use: 2,137 kWh; 223 cooling + 1,914 heating
Estimated running cost: $705 / year; $59 / month · $7,052 over 10 years
Capacity: 5 kW cooling; 6 kW heating

1% less 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 54% of them.

Across all 3,612 air conditioner registrations sold in Australia, it uses less than 74% (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.
