- Energy rating (cooling)
- 3.5
- Heating: 2
- Annual electricity use
- 3,062 kWh
- 372 cooling + 2,690 heating
- Estimated running cost
- $1,010 / year
- $84 / month · $10,105 over 10 years
- Capacity
- 7.1 kW cooling
- 8 kW heating
3% less electricity than the median of 203 comparable 7 kW reverse cycle split system registrations (3,143 kWh a year) in the cold zone. Uses less than 65% of them.
Across all 3,612 air conditioner registrations sold in Australia, it uses less than 61% (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.
