Westinghouse HSV187HWAE/HSV187HWAI is a 5.1 kW reverse cycle split system heat pump registered for sale in New Zealand under the trans-Tasman E3 energy rating scheme (registration AAC7553).
- Energy rating (cooling)
- 4.5
- Heating: 2.5
- Annual electricity use
- 2,062 kWh
- 230 cooling + 1,832 heating
- Estimated running cost
- $680 / year
- $57 / month · $6,805 over 10 years
- Capacity
- 5.1 kW cooling
- 6.1 kW heating
4% less electricity than the median of 236 comparable 5 kW reverse cycle split system registrations (2,154 kWh a year) in the cold zone. Uses less than 72% of them.
Across all 3,612 air conditioner registrations sold in Australia, it uses less than 76% (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.
