A high efficiency heater will save energy and cost less to run. By choosing a system that is the right size for your home, you can avoid paying for energy you don't need.
Compare star ratings
Use the heater's energy rating label to compare the efficiency of different models. The heating efficiency is shown in the red band. The more stars, the more you will save on your heating costs.
Compare the annual energy consumption using the number in the energy consumption box. The lower the consumption number, the less energy you use and the more you save.
Buy to save in the long run
Select a heating system that is the right size for your needs and room sizes: space or room heaters for living areas, or ducted heating to warm more rooms at the same time.
When buying a gas space-heater or a gas ducted heating system make sure it has an energy rating of at least 4 stars.
Buy a unit with a thermostat and timer so that you can use your heating system efficiently.
