Fujitsu heat pumps / air conditioners for sale in Australia and New Zealand are transitioning to displaying the NEW Zoned Energy Rating Label (ZERL) The new label provides a seasonal efficiency rating for three distinct climate zones across Australia and New Zealand - HOT, AVERAGE and COLD.
OLD vs NEW Zoned Energy Rating Label for Fujitsu Heat Pumps / Air Conditioners
Understanding the difference between the old Energy Rating Label (ERL) and the NEW Zoned Energy Rating Label (ZERL).
The star rating on the old label measured how much cooling or heating output was achieved per unit of power. It related to the efficiency of the heat pump / air conditioner at a particular temperature but did not take into account consumer usage patterns in different locations of Australia and New Zealand to determine typical electricity use.
The star ratings on the new label reflect how the heat pump / air conditioner will perform over a range of temperatures and allows an annual electricity figure to be calculated (these are the blue and red ‘kWh per year’ figures on the ZERL).

Find out what size heat pump / air conditioner you need for your space. A family has a 3 bedroom home and would like to purchase a heat pump / air conditioning unit for their open plan living area. They sought advice online and have been advised by their retailer / installer that they would need a 7kW unit.
Figure out what zone you're in. The family live in Wellington, which is in the ‘COLD’ zone, so they refer to the star ratings and energy use in the black shaded ‘COLD’ zone to review the heat pumps / air conditioner’s performance. Please note the whole of New Zealand is in the 'COLD' zone.
Compare star ratings on heat pump / air conditioner performance in your zone. The family compares two heat pump / air conditioning units based on their energy efficient star ratings and energy use. They decide to purchase the top unit as it is more energy efficient and will consume less energy ultimately making it more efficient.
Work out how much it costs to run per year. The family determine that the cost to run this heat pump / air conditioner per year would be $271 based on an electricity tariff of $0.29 kW per hour.
Why the change?
To provide consumers with more information about expected energy use for Fujitsu heat pumps / air conditioners, based on where they live. The new label will assist consumers in evaluating the energy use of various heat pump / air conditioning products in order to help them save money on their energy bills.
The new labels provide estimated performance information about likely energy use by the heat pump / air conditioner over the course of the year.
Labels on ducted systems are voluntary, so not all products will have one.
Are the stars the same? Can I compare the stars on a product with the old label and another product with the new label? No, they are not the same. Due to the different methods of calculating the star ratings, you should not compare the star rating on the old label versus the new Zoned Energy Rating Labels.
The star ratings on the old label measured how much cooling or heating output was achieved per unit of power. It related to the efficiency of the heat pump / air conditioner at a particular temperature, but did not take into account consumer usage patterns or climate to determine typical electricity use.
How loud is that noise level on the label?
For comparison, here are some common sound power levels (in decibles)
30dBA: typical noise in a quiet home
50dBA: inside of a quiet car while driving
60dBA: having a typical conversation
75dBA: an operating vacuum cleaner
The noise levels on the label are measured with the heat pump / air conditioner running at full capacity in cooling mode. For much of the time a heat pump / air conditioner is running, its noise level will be lower than the level indicated on the label.
