- Energy rating (cooling)
- 2.5
- Heating: 2
- Annual electricity use
- 2,095 kWh
- 279 cooling + 1,816 heating
- Estimated running cost
- $691 / year
- $58 / month · $6,914 over 10 years
- Capacity
- 4.5 kW cooling
- 5 kW heating
3% 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 64% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 75% (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.
