- 1.5
- Heating: 1
- Annual electricity use
- 8,580 kWh
- 1,252 cooling + 7,328 heating
- Estimated running cost
- $2,831 / year
- $236 / month · $28,314 over 10 years
- Capacity
- 14.5 kW cooling
- 14.9 kW heating
27% more electricity than the median of 124 comparable 14 kW reverse cycle ducted split system registrations (6,763 kWh a year) in the cold zone. Uses less than 2% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 16% (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.
