Westinghouse WSD27HWB-I/WSD27HWA-E Heat Pump
Westinghouse WSD27HWB-I/WSD27HWA-E is a 2.6 kW reverse cycle split system heat pump registered for sale in New Zealand under the trans-Tasman E3 energy rating scheme (registration AAC7557).
- Energy rating (cooling)
- 6.5
- Heating: 3
- Annual electricity use
- 1,093 kWh
- 90 cooling + 1,003 heating
- Estimated running cost
- $361 / year
- $30 / month · $3,607 over 10 years
- Capacity
- 2.6 kW cooling
- 3.5 kW heating
2% more electricity than the median of 178 comparable 2.5 kW reverse cycle split system registrations (1,074 kWh a year) in the cold zone. Uses less than 45% of them.
Across all 3,612 air conditioner registrations sold in Australia, it uses less than 87% (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 WSD27HWB-I running cost by climate zone
| Climate zone | kWh / year | Per year | 10 years |
|---|---|---|---|
| Cold zone | 1,093 | $361 | $3,607 |
| Mixed zone | 528 | $174 | $1,742 |
| Hot zone | 463 | $153 | $1,528 |
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.
