New Energy Rating Labels For Heat Pumps

We have created a useful guide to help you understand and interpret the newly introduced Zoned Energy Rating Label (ZERL) for heat pumps by the Australian Government. This guide will provide information on what these labels offer, how to read them effectively, and provide some fundamental knowledge to assist you in selecting the most suitable and energy-efficient heat pump for your needs!


Energy Rating Labels have been in existence for more than three decades and enable you to assess and compare the energy efficiency and operational expenses of various household appliances prior to making a purchase.


Star ratings indicate the efficiency of a heat pump in heating or cooling mode compared to other heat pumps of similar size. A higher number of stars signifies greater efficiency in comparison to other models of the same size.

Heat pumps generally receive a star rating ranging from 1 to 6. However, as technology improves, so does energy efficiency. Our Avanti PLUSĀ® split system serves as a prime example of this advancement. It is exceptionally efficient and boasts industry-leading energy ratings. The 2.0kW model, in particular, holds a 7-star 'super efficiency' rating, which currently stands as the highest among heat pumps in New Zealand.

The updated heat pump label now offers additional details such as the variation in energy efficiency for different heat pump models. This includes their performance in both heating and cooling modes across three climate zones: hot, average, or cold. Furthermore, it provides estimates of the annual energy consumption for each model within these zones. This valuable information on climate zone performance allows homeowners to gauge the efficiency of a heat pump when considering its installation in their own residence.

Since most New Zealanders use heat pumps for heating more frequently than for cooling, it is recommended to consider the energy efficiency and annual energy consumption ratings in the 'Cold' zone for a more accurate indication of the heat pump's performance.
