Westinghouse WSD73HWA-E/WSD73HWA-I Air Conditioner
Westinghouse WSD73HWA-E/WSD73HWA-I is a 7.3 kW reverse cycle split system air conditioner registered under Australia’s Energy Rating (GEMS) scheme (registration AAC7554).
- Energy rating (cooling)
- 3.5
- Heating: 3
- Annual electricity use
- 1,563 kWh
- 565 cooling + 998 heating
- Estimated running cost
- $500 / year
- $42 / month · $5,002 over 10 years
- Capacity
- 7.3 kW cooling
- 8.3 kW heating
2% less electricity than the median of 211 comparable 7 kW reverse cycle split system registrations (1,600 kWh a year) in the mixed zone. Uses less than 63% of them.
Across all 3,680 air conditioner registrations sold in Australia, it uses less than 62% (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.
Westinghouse WSD73HWA-E running cost by climate zone
| Climate zone | kWh / year | Per year | 10 years |
|---|---|---|---|
| Cold zone | 3,063 | $980 | $9,802 |
| Mixed zone | 1,563 | $500 | $5,002 |
| Hot zone | 1,808 | $579 | $5,786 |
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.
