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 2-star house in a Melbourne climate, heating to 20°C all day on:
The calculations are based on an electricity tariff of 22.8c/kWh (peak) and 16.54/kWh (off peak). Gas tariffs are based on a declining block structure, which means the unit cost of gas decreases as gas use (or area being heated) increases.
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.
Greenhouse gas emissions are based on:
