- 4
- Heating: 2
- Annual electricity use
- 3,307 kWh
- 382 cooling + 2,925 heating
- Estimated running cost
- $1,091 / year

- Capacity
- 8.5 kW cooling
- 8.7 kW heating
About the same electricity as the median of 22 comparable 8 kW reverse cycle fixed registrations (3,319 kWh a year) in the cold zone. Uses less than 50% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 57% (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.
