Westinghouse WWH22HWC is a 2.3 kW reverse cycle window / wall heat pump registered for sale in New Zealand under the trans-Tasman E3 energy rating scheme (registration AAC10113).
- Energy rating (cooling)
- 1.5
- Heating: 0.5
- Annual electricity use
- 1,311 kWh
- 187 cooling + 1,124 heating
- Estimated running cost
- $433 / year
- $36 / month · $4,326 over 10 years
- Capacity
- 2.3 kW cooling
- 2 kW heating
15% less electricity than the median of 21 comparable 2.5 kW reverse cycle window / wall registrations (1,546 kWh a year) in the cold zone. Uses less than 91% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 83% (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.
