- Energy rating (cooling)
- 1.5
- Annual electricity use
- 187 kWh
- Estimated running cost
- $62 / year
- $5 / month · $617 over 10 years
- Capacity
- 2.3 kW cooling
13% less electricity than the median of 9 comparable 2.5 kW cooling only window / wall registrations (215 kWh a year) in the cold zone. Uses less than 56% of them.
Across all 3,612 air conditioner registrations sold in Australia, it uses less than 98% (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.
