Westinghouse WSD36HWA-E/WSD36HWA-I Air Conditioner
Westinghouse WSD36HWA-E/WSD36HWA-I is a 3.6 kW reverse cycle split system air conditioner registered under Australia’s Energy Rating (GEMS) scheme (registration AAC7559).
- Energy rating (cooling)
- 5.5
- Heating: 3
- Annual electricity use
- 701 kWh
- 209 cooling + 492 heating
- Estimated running cost
- $224 / year
- $19 / month · $2,243 over 10 years
- Capacity
- 3.6 kW cooling
- 4.4 kW heating
1% less electricity than the median of 196 comparable 3.5 kW reverse cycle split system registrations (709 kWh a year) in the mixed zone. Uses less than 53% of them.
Across all 3,680 air conditioner registrations sold in Australia, it uses less than 85% (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 WSD36HWA-E running cost by climate zone
| Climate zone | kWh / year | Per year | 10 years |
|---|---|---|---|
| Cold zone | 1,411 | $452 | $4,515 |
| Mixed zone | 701 | $224 | $2,243 |
| Hot zone | 679 | $217 | $2,173 |
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.
