- 9 kW heating
4% less electricity than the median of 125 comparable 8 kW reverse cycle split system registrations (1,834 kWh a year) in the mixed zone. Uses less than 65% of them.
Across all 3,680 air conditioner registrations sold in Australia, it uses less than 55% (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 mixed zone (Richmond NSW climate: Sydney, Melbourne, Adelaide, Perth). Mixed climate zone shown by default (Sydney, Melbourne, Adelaide, Perth); switch to cold or hot. Cost = kWh × 32c/kWh in AUD; 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 | $1,177 | $11,766 |
| Mixed zone | 1,762 | $564 | $5,638 |
| Hot zone | 1,971 | $631 | $6,307 |
At 32c/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.
