- Capacity
- 4.8 kW cooling
4% less electricity than the median of 20 comparable 5 kW cooling only split system registrations (250 kWh a year) in the cold zone. Uses less than 65% of them.
Across all 3,611 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.
