Westinghouse WSD27HWC-E / WSD27HWC-I is a 2.7 kW reverse cycle split system air conditioner registered under Australia’s Energy Rating (GEMS) scheme (registration AAC10139).
- Energy rating (cooling)
- 6
- Heating: 3.5
- Annual electricity use
- 498 kWh
- 143 cooling + 355 heating
- Estimated running cost
- $159 / year
- $13 / month · $1,594 over 10 years
- Capacity
- 2.7 kW cooling
- 3.3 kW heating
8% 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 66% 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 WSD27HWC-E running cost by climate zone
| Climate zone | kWh / year | Per year | 10 years |
|---|---|---|---|
| Cold zone | 1,015 | $325 | $3,248 |
| Mixed zone | 498 | $159 | $1,594 |
| Hot zone | 461 | $148 | $1,475 |
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.
