Gree GWH28AGEXH-K6DNA1A/O / GWH28AGEXH-K6DNA1A/I is a 8.5 kW reverse cycle split system heat pump registered for sale in New Zealand under the trans-Tasman E3 energy rating scheme (registration AAC8223).
- Energy rating (cooling)
- 4
- Heating: 2
- Annual electricity use
- 3,551 kWh
- 387 cooling + 3,164 heating
- Estimated running cost
- $1,172 / year
- $98 / month · $11,718 over 10 years
- Capacity
- 8.5 kW cooling
- 9 kW heating
2% less electricity than the median of 120 comparable 8 kW reverse cycle split system registrations (3,622 kWh a year) in the cold zone. Uses less than 64% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 53% (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.
