Gas Heating Spend per Year

The one number only you know. Add up the heating share of your winter gas bills — not cooking or hot water.

What Would You Replace It With?

Installed Cost after Rebate

Out of pocket after any VEU discount, not the list price. Type your own quote here and the selector above switches to "my own figure".

Electric Running Cost, as a Share of the Gas Figure

Reverse cycle moves heat rather than making it, so it lands near half. Nudge up if you are on a pricey electricity plan.

Heating Shifted into the 3-Hour Free Electricity Window

The Victorian Midday Power Saver's three free hours run 11am to 2pm from 1 October 2026, so only pre-warming and daytime heating can move. 10% is cautious. More information.

Disconnect Gas Entirely Removes the daily gas supply charge, about $ a year. Leave off if a gas cooktop or hot water stays.

Year by Year: The Numbers behind the Chart

Cumulative figures: everything spent on each path up to that year, the electric path starting with the install. The highlighted row is the year the lines cross. Estimate, not a quote.

What Sits behind These Numbers

Why Electric Running Costs Land near Half

A reverse-cycle system moves heat rather than making it: roughly four units of heat for every unit of electricity (a coefficient of performance around 4). A gas ducted unit turns about 80% of the gas you pay for into heat in the room. At Victorian retail rates that puts electric running costs at about half the gas figure. The slider lets you set anything from 30% to 80%.

The Free Three Hours

The Supply Charge Is the Quiet One

Every day you stay connected to gas you pay a daily supply charge, about $ a year, before you burn any gas. It only disappears when the meter is disconnected. If a gas cooktop or gas hot water stays, leave the toggle off and the charge stays in the gas column.

Installed Cost and the Rebate

What Is Not Counted Here

The same unit also cools in summer at no extra purchase cost, and no cooling running cost is charged to either line. The gas ducted unit you would have to replace anyway, typically $5,000 to $7,000, is not credited against the install either. If you would otherwise be buying separate cooling or replacing the gas unit, both would tend to improve the electric case beyond what the chart shows.
