Heat pump vs gas heating in Melbourne

How efficient reverse-cycle heat pumps compare with gas heating on running costs for Melbourne homes — and why solar changes the maths.

Why heat pumps are cheaper to run

A reverse-cycle heat pump doesn't create heat — it moves it, delivering several units of heating for every unit of electricity it uses (a measure called COP). Modern units achieve a COP well above 3, meaning they're far more efficient than resistive electric heating and, for many Melbourne homes, cheaper to run than ducted gas — especially as gas prices rise and supply charges add up.

The solar factor

The real advantage appears when a heat pump runs on your own solar. Daytime heating and cooling powered by excess generation costs close to nothing, which gas can never match because it's a fuel you always pay for. Designing heating alongside solar — so loads line up with generation — is the core of our heat pump and air conditioning work.

Beyond running cost

  • One system, both jobs — a reverse-cycle heat pump heats in winter and cools in summer, replacing separate appliances.
  • Removing gas — going all-electric can let you drop the gas connection and its daily supply charge entirely.
  • Comfort and control — zoning and inverter control keep temperatures steady and efficient.
  • Winter performance — we select units rated for Melbourne winters, not just summer cooling.

Which is right for your home?

It depends on your existing setup, insulation and whether you have solar. For most Melbourne homes — particularly those adding or already running solar — an efficient heat pump is the lower-cost, lower-emissions choice over gas.

FAQ

Frequently asked questions

Is a heat pump cheaper to run than gas heating in Melbourne?

For many Melbourne homes, yes — a modern reverse-cycle heat pump delivers several units of heat per unit of electricity, and running it on solar makes daytime heating very cheap. We model your specific numbers before recommending anything.

Do heat pumps work in Melbourne winters?

Yes. Modern reverse-cycle units are designed for climates colder than Melbourne and maintain efficient output in winter. We select units rated for winter performance, not just summer cooling.

Should I replace my gas ducted heating with a heat pump?

Often it's worth it, especially combined with solar — running costs are typically well below ducted gas and you can remove the gas supply charge. We assess your home first and show you the comparison.
