Westinghouse WSD27HWB-I/WSD27HWA-E is a 2.6 kW reverse cycle split system air conditioner registered under Australia’s Energy Rating (GEMS) scheme (registration AAC7557).
- Energy rating (cooling)
- 6
- Heating: 3
- Annual electricity use
- 528 kWh
- 142 cooling + 386 heating
- Estimated running cost
- $169 / year
- $14 / month · $1,690 over 10 years
- Capacity
- 2.6 kW cooling
- 3.5 kW heating
3% less electricity than the median of 192 comparable 2.5 kW reverse cycle split system registrations (544 kWh a year) in the mixed zone. Uses less than 56% of them.
Across all 3,681 air conditioner registrations sold in Australia, it uses less than 93% (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 WSD27HWB-I running cost by climate zone
| Climate zone | kWh / year | Per year | 10 years |
|---|---|---|---|
| Cold zone | 1,093 | $350 | $3,498 |
| Mixed zone | 528 | $169 | $1,690 |
| Hot zone | 463 | $148 | $1,482 |
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.
