Understanding The New Zoned Energy Rating Labels for Heat Pumps
With the Australian Government having announced a new Zoned Energy Rating Label (ZERL) for heat pumps we’ve put together a handy guide on what these new labels offer, how to read them, as well as covering some basics to help you choose the best and most efficient heat pump for you!
What are energy rating labels?
Energy Rating Labels (in one form or another) have been around for over 30 years and allow you to compare the energy efficiency and running costs of different household appliances before purchasing.
What Is The Star Rating?
The star ratings refer to how efficient a heat pump is in heating or cooling mode relative to other models of the same size. More stars means more efficient when compared to other models of the same size.
Most heat pumps are given between 1 and 6 stars however as technology gets better, as does the energy efficiency! A perfect example of this is our super efficient Avanti PLUS® split system – which boasts industry leading energy ratings, including the 2.0kW model which currently has a 7-star ‘super efficiency’ rating – the highest of any heat pump in New Zealand! Learn more about the Avanti PLUS® in our ‘Product in Focus’ blog post.
What information do the new zoned ENERGY rating labels provide?
- How much cooling and heating power a heat pump can provide
- How efficient a heat pump is depending on where you live
- How much electricity a heat pump will use, depending on where you live
- How much noise the indoor and outdoor unit produce
The new heat pump label provides more information including the difference in energy efficiency of each model of heat pump, in heating and cooling mode across three climate zones – hot, average or cold as well as estimated annual energy consumption of each model within these three zones. This climate zone performance information helps you get a better understanding of how efficient a heat pump would be when installed in your own home.
How do i read the new star energy label?
The below graphic helps you understand each different section of the label.
Given most New Zealanders would use a heat pump’s heating function more often than the cooling function and because heat pumps have different energy ratings for heating and cooling, you should refer to the ‘Cold’ zone for a closer indication of the heat pump’s energy efficiency and annual energy consumption.
how do i decide which size unit I need?
You can refer to our handy split system room sizing chart for a guide on which side might be best for your space however we also recommend speaking to an authorised installer to get a proper quote. Visit our Request a Quote page, leave your details and we’ll get an authorised installer to get in touch!
