Westinghouse WSD70HWC-E / WSD70HWC-I Air Conditioner
Westinghouse WSD70HWC-E / WSD70HWC-I is a 7 kW reverse cycle split system air conditioner registered under Australia’s Energy Rating (GEMS) scheme (registration AAC10141).
- Energy rating (cooling)
- 3.5
- Heating: 2.5
- Annual electricity use
- 1,543 kWh
- 558 cooling + 985 heating
- Estimated running cost
- $494 / year
- $41 / month · $4,938 over 10 years
- Capacity
- 7 kW cooling
- 7.7 kW heating
4% 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 68% 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 WSD70HWC-E running cost by climate zone
| Climate zone | kWh / year | Per year | 10 years |
|---|---|---|---|
| Cold zone | 2,984 | $955 | $9,549 |
| Mixed zone | 1,543 | $494 | $4,938 |
| Hot zone | 1,784 | $571 | $5,709 |
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.
