Estimate how much your heating is costing you every year.
On this page
This page provides approximate annual running costs and greenhouse gas emissions for a range of types and sizes of heating options.
These should be used as a guide only. Actual energy costs will depend on:
The calculations are based on an average 2-star house in a Melbourne climate.To estimate the running cost for a cold climate, such as Ballarat, multiply these figures by 1.5. For a warm climate, such as Mildura, multiply these figures by 0.8.To estimate the running cost for a 5-star house in a Melbourne climate multiply these figures by 0.4. For a 6-Star house multiply these figures by 0.3.The calculations for slow combustion wood heaters only include greenhouse gas emissions. Wood heaters can also produce smoke pollution.
Read EPA’s advice on reducing wood smoke pollution.
How we calculated the energy costs
The figures in the tables above are approximate costs per year. They’re based on an average existing pre-2005 house in a Melbourne climate, heating to 20°C.
The calculations are based on an electricity tariff of 22.8c/kWh (peak) and 16.54/kWh (off peak). Natural gas tariffs are based on the standing offer of a major gas retailer using a typical "declining block" structure for a house with gas heating, water heating and cooking, which means the more gas that is used during each billing period (e.g. the larger the area being heated), the cheaper the unit cost of the gas.
Gas tariffs used for central heating are:
Gas tariffs used for room heating are:
The electricity and gas tariffs do not include any pay on time discount or any fixed supply charges.
10-year greenhouse gas emissions are based on the estimated emission coefficients of the different fuels over the next ten years:
Figures have been updated to reflect the gas price increases as of 1 Feb 2023. Prices of electricity and other fuels remain the same. We expect the electricity price to also rise in mid-2023. The 10-year emission coefficient for electricity has been updated (it has gone down a bit), based on the emission coefficient data released in 2022.
