- Energy rating (cooling)
- 3.5
- Heating: 3
- Annual electricity use
- 1,030 kWh
- 120 cooling + 910 heating
- Estimated running cost
- $340 / year

4% less electricity than the median of 177 comparable 2.5 kW reverse cycle split system registrations (1,073 kWh a year) in the cold zone. Uses less than 57% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 88% (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.
