Mitsubishi Heavy Industries SRK/DXK_20/06ZSA-W is a 2 kW reverse cycle split system heat pump registered for sale in New Zealand under the trans-Tasman E3 energy rating scheme (registration AAC8734).
- Energy rating (cooling)
- 4
- Heating: 3
- Annual electricity use
- 858 kWh
- 93 cooling + 765 heating
- Estimated running cost
- $283 / year
- $24 / month · $2,831 over 10 years
- Capacity
- 2 kW cooling
- 2.7 kW heating
4% more electricity than the median of 63 comparable 2 kW reverse cycle split system registrations (829 kWh a year) in the cold zone. Uses less than 43% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 91% (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.

| Hot zone | 452 | $149 | $1,492 |
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.
