Gree GWH28ATEXF-K6DNA1A/O / GWH28ATEXF-K6DNA4A/I is a 8.2 kW reverse cycle split system air conditioner registered under Australia’s Energy Rating (GEMS) scheme (registration AAC8258).
- Energy rating (cooling)
- 3.5
- Heating: 2.5
- Annual electricity use
- 1,784 kWh
- 675 cooling + 1,109 heating
- Estimated running cost
- $571 / year
- $48 / month · $5,709 over 10 years
- Capacity
- 8.2 kW cooling
- 9 kW heating
3% 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 61% 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 | 3,690 | $1,181 | $11,808 |
| Mixed zone | 1,784 | $571 | $5,709 |
| Hot zone | 2,033 | $651 | $6,506 |
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.
