A label showing climate zones

The new Zoned Energy Rating Label tells you which heat pumps/air conditioners will perform best in different climate zones of New Zealand and Australia.

The label includes how much electricity the unit will use per year for heating and cooling, and how loud the unit is when running.

When the Regulations come into force, portable air conditioners will need to display the Zoned Energy Rating Label.

What you need to know

Retailers and installers

Retailers must display the new label correctly.

Retailers and installers need to understand the changes and the new label to explain these to customers.

Details on the new regulations

You need to comply with the updated regulations when they come into force. We will give at least six months’ notice through our Efficient Products newsletter and gazette notification.

In the meantime you must either:

  • Comply with the current requirements
  • Voluntarily comply with the new requirements.

Performance calculations

Energy Rating Label Zoned Energy Rating Label
  • Star ratings for heating (or cooling) are based on the efficiency of the heat pump at one outside temperature of 7°c (35°c for cooling).
  • Star ratings and energy used for heating (or cooling) are based on the test information of the heat pump at two outside temperatures at 7°c and 2°c (35°c for cooling). Uses test information  to determine the heat pump’s performance (heat output, and efficiency) across a range of climate temperatures.
  • The calculation takes into account standby power, and assumes standby time of 6760 hours a year.
  • The calculation takes into account standby power, and time at standby is dependent on zone.
  • The calculation assumes that the heat pump is heating (or cooling) for 2000 hours a year, and does not take into account the climate the heat pump may be operating in.
  • Uses climate data (dependent on zone) to estimate the number of hours the heat pump will be on for heating (or cooling) across a range of climate temperatures.
