Westinghouse WSD27HWC-E / WSD27HWC-I is a 2.7 kW reverse cycle split system heat pump registered for sale in New Zealand under the trans-Tasman E3 energy rating scheme (registration AAC10139).
- Energy rating (cooling)
- 6.5
- Heating: 3
- Annual electricity use
- 1,015 kWh
- 90 cooling + 925 heating
- Estimated running cost
- $335 / year
- $28 / month · $3,350 over 10 years
- Capacity
- 2.7 kW cooling
- 3.3 kW heating
5% less electricity than the median of 177 comparable 2.5 kW reverse cycle split system registrations (1,073 kWh a year) in the cold zone. Uses less than 65% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 89% (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 WSD27HWC-E running cost by climate zone
| Climate zone | kWh / year | Per year | 10 years |
|---|---|---|---|
| Cold zone | 1,015 | $335 | $3,350 |
| Mixed zone | 498 | $164 | $1,643 |
| Hot zone | 461 | $152 | $1,521 |
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.
