Westinghouse WSD70HWC-E / WSD70HWC-I Heat Pump
Westinghouse WSD70HWC-E / WSD70HWC-I is a 7 kW reverse cycle split system heat pump registered for sale in New Zealand under the trans-Tasman E3 energy rating scheme (registration AAC10141).
- Energy rating (cooling)
- 4
- Heating: 2
- Annual electricity use
- 2,984 kWh
- 349 cooling + 2,635 heating
- Estimated running cost
- $985 / year
- $82 / month · $9,847 over 10 years
- Capacity
- 7 kW cooling
- 7.7 kW heating
5% less electricity than the median of 203 comparable 7 kW reverse cycle split system registrations (3,143 kWh a year) in the cold zone. Uses less than 78% of them.
Across all 3,611 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 cold zone (Canberra climate: Canberra, Hobart, Ballarat, alpine areas). All of New Zealand is the cold zone on the Zoned Energy Rating Label. Cost = kWh × 33c/kWh in NZD; 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 | $985 | $9,847 |
| Mixed zone | 1,543 | $509 | $5,092 |
| Hot zone | 1,784 | $589 | $5,887 |
At 33c/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.
