Central Heating vs Ducted Heating: What’s the Difference?

When discussing home heating, the terms central heating and ducted heating are often used interchangeably. While related, they aren’t exactly the same, and understanding the difference can help you choose the best option for your home.

How Each System Works

Central heating is a broad term that covers any system where heat is generated in one location and then distributed throughout the home. This can include ducted systems or other less common types, such as hydronic heating. A ducted heating system specifically refers to a setup where warm air is produced by a central unit (often gas) and delivered to each room via ducts.

Comparison Table

Feature	Central Heating	Ducted Heating
Definition	Any system heating from one central source	Uses a central unit to heat air and distribute it via ducts
Common Types	Ducted heating, hydronic heating (new builds only)	Gas ducted heating, electric ducted heating
Installation	Hydronic requires pipes in walls/floors and is difficult to retrofit; ducted air can be added to many existing homes	Ductwork installed in ceiling or underfloor; can be retrofitted in many homes
Energy Source	Gas or electricity depending on system	Mainly natural gas or LPG (some electric options)
Running Costs	Varies by system type; hydronic generally higher install cost	Efficient for whole-home heating, especially with gas
Best Suited For	Hydronic for new builds; ducted systems for most existing homes	Homes with or able to install ductwork

Installation Differences

Hydronic central heating can only realistically be installed during construction due to the need for in-floor or in-wall pipework. Retrofitting it is costly and disruptive. Ducted heating, however, can often be fitted to existing homes with ceiling or underfloor space, making it a more flexible option for upgrades.

Running Costs

Gas ducted heating is generally the most cost-effective whole-home option in Melbourne, particularly for larger homes. Hydronic systems can deliver a comfortable, consistent heat but come with higher upfront installation costs and are impractical to add to an existing property.

Suitability for Different Homes

If your home already has ductwork or the space to install it, ducted heating is usually the easiest and most affordable choice. Central heating in the hydronic form is best suited to new builds or major renovations.
