- Energy rating (cooling)
- 3.5
- Heating: 2
- Annual electricity use
- 3,677 kWh
- 410 cooling + 3,267 heating
- Estimated running cost
- $1,213 / year
- $101 / month · $12,134 over 10 years
- Capacity
- 8.2 kW cooling
- 9 kW heating
2% more electricity than the median of 120 comparable 8 kW reverse cycle split system registrations (3,622 kWh a year) in the cold zone. Uses less than 43% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 51% (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.
Gree running cost by climate zone
| Climate zone | kWh / year | Per year | 10 years |
|---|---|---|---|
| Cold zone | 3,677 | $1,213 | $12,134 |
| Mixed zone | 1,762 | $581 | $5,815 |
| Hot zone | 1,971 | $650 | $6,504 |
At 33c/kWh. Formula: cost = annual kWh × price. The kWh figure is the label’s residential estimate for that zone; commercial-profile figures are in the specifications.
