All ducted gas heaters are supplied with an Energy Star rating label. These labels provide details of the amount of gas each unit will consume over a normal winter. It’s an indicative guide that outlines the running cost of the heater in terms of annual energy usage. The more efficient the heater the higher the star rating. The higher the star rating the more money you can potentially save on running costs. On average an increase of one star means energy savings of approximately 10 percent

* The running cost data used to determine these results is based on AS/NZS 5263.1.6:2020. This standard determines a house heat load of 0.2 Mega joules per hour per cubic meter of living area heated of 600 hours of operation (100 days at 6 hours per day). Savings are specifically based as a comparison with a three star ducted gas heater. Calculations for gas usage are based on the Average House Floor Area (with 2400mm ceiling) for new homes as published by the Australian Bureau of Statistics from a study commissioned by Commsec in 2013. The calculations were specifically based on the Annual Energy Consumption in accordance with the AGA Star ratings for Ducted Gas systems and using a gas cost of 1.6 cents per MJ/HR. Savings should be seen as a guide only as actual heating performance and therefore savings, may vary due to a number of factors including home construction and size, gas costs, heater usage, zoning and thermal insulation.
