Gas Heating vs Reverse Cycle: Which Is Cheaper to Run in Melbourne?
With rising energy costs, many homeowners across Melbourne and the Diamond Valley are asking the same question:
“Is gas heating or reverse-cycle air conditioning cheaper to run?”
Both systems are popular in Victorian homes, but running costs, efficiency, and long-term value can vary significantly depending on how your home is used. In this article, we compare gas ducted heating vs reverse-cycle heating to help you make the most cost-effective choice for your household.
What Is Gas Heating?
Gas heating (most commonly ducted gas heating) uses natural gas to heat air, which is then distributed through ducts and vents throughout the home either from the ceiling or floor vents.
Gas heating has traditionally been very popular in Melbourne homes due to its strong heating performance during cold winters.
Gas heating is best suited for:
- Whole-home heating only
- Homes already connected to natural gas
- Households that want fast, powerful heat
- Homes with existing ducted gas systems
What Is Reverse-Cycle Heating?
Reverse-cycle heating uses refrigerant that goes from the outdoor unit to the indoor unit. It is commonly delivered via split systems or ducted reverse-cycle air conditioning.
Reverse-cycle systems provides both heating and cooling, making them a versatile options for Melbourne’s changing climate.
Reverse-cycle heating is best suited for:
- Heating and cooling in one system
- Energy-efficient homes
- Homes with solar power
- Split system or ducted air conditioning installations
Gas Heating vs Reverse Cycle: Running Cost Comparison
Energy Efficiency
Gas Heating – Efficient at producing heat – Efficiency depends on the age and condition of the system – Older systems can be costly to run
Reverse-Cycle Heating – Extremely energy efficient – One of the most efficient electric heating options available
Running Costs in Melbourne Homes
Gas Heating – Gas prices in Victoria have increased in recent years – Higher running costs for whole-home heating – No cooling function (separate system required)
Reverse-Cycle Heating – Generally cheaper to run for most homes – Lower costs when heating only occupied rooms – Even more cost-effective when paired with solar power
Whole-Home vs Zoned Heating
Gas Heating – Often heats the entire home – Limited zoning in older systems – Can waste energy heating unused rooms
Reverse-Cycle Heating – Excellent zoning options – Ideal for heating specific rooms only – Better control over energy use
Installation and Upgrade Costs
Gas Heating – Lower replacement cost if ducting already exists – New installations can be expensive – Gas connections may not be available in all areas
Reverse-Cycle Heating – Higher upfront cost for ducted systems – Split systems allow staged installation – Long-term savings often outweigh initial cost
Which Is Cheaper to Run?
For most modern Melbourne homes, reverse-cycle heating is cheaper to run than gas heating, especially when: – You heat only occupied rooms – Your home is well insulated – You have solar power installed
Gas heating may still suit some homes, particularly those with existing systems and high heating demands, but rising gas prices are making reverse-cycle heating the more economical long-term option.
Our Recommendation
The cheapest heating option depends on: – Your home’s insulation and layout – How many rooms you heat regularly – Whether you already have gas or solar power – Your long-term energy goals
