How ducted heating keeps you warm

Ducted heating uses a central system and network of ducts to distribute warm air throughout connected areas of your home. Depending on the system installed, heating can be powered by gas or electricity, giving households different ways to achieve comfortable whole-home heating.

What to weigh up with ducted heating

The right ducted heating system depends on more than the size of your home. Existing ductwork, zoning preferences and how much of the property you want to heat can all shape the setup.

Temperature Changes

How do you want to control each area

Consider whether you want the whole home heated at once or greater control over selected zones. The right setup can make day-to-day heating more flexible.

Your existing ductwork

If your home already has a ducted system, the condition and layout of the ducting should be assessed when replacing or upgrading the heating unit.
Planning

How much space do you need to heat

Home size, layout and the rooms you want heated influence the system requirements. Getting the setup right helps deliver comfortable heating where you need it.
