What is Ducted Heating?
Ducted central heating comprises a central heating unit, which is connected to a series of outlets. Positioned strategically throughout your home, these outlets, or ducts, are installed either in the floor or ceiling. Positioning of the heating unit depends on your house. If your house is built on a concrete slab, the unit is installed in the roof. If it has space underneath or a very low roof line, the unit is installed outside or under the floor. The duct work, which connects the outlets to the heating unit, is neatly tucked away out of sight.
Stop before you shop
Heating is a long term investment so before you even begin looking at heating systems, there are a few things you should consider. For instance, how will future lifestyle changes affect your heating needs? Think ahead, and purchase a system that fulfills your current needs as well as your future ones. And keep in mind that a good heating system increases the value of your home. The money you spend now is sure to pay off later. Finally, determine how many rooms you want to heat at any given time. Figure this out, and you’re half way to finding the heating system that’s right for you.
Whole house heating
With ducted heating you don’t have to walk out of a warm room into a cold one. You can be watching TV while the kids are in bed and everyone stays warm.
Gas Ducted central heating is the most efficient way to heat your entire house. You can save up to $300* per year in operating costs to heat your entire home using a high efficiency gas ducted heater compared to using gas space heaters.
A household using electrical appliances for heating produces three times** more greenhouse gas emissions than a household using ducted gas appliances.

Move to a warm zone
Ducted central heating offers heating flexibility through zoning. Zoning enables you to divide your home into sections so living areas can be heated during the day and sleeping areas at night, or whatever suits you. Zoning is not only practical but economical. It can reduce your gas bill by up to $200 pa. in a typical home. So don’t forget to ask about zoning when you speak to your dealer.
Why ducted gas heating?
In most areas, electricity costs are rising faster than gas, so natural gas heating offers a cost-effective alternative. Plus it’s kinder to the environment, as it produces fewer greenhouse gas emissions than most other forms of heating.
- Australian Gas Association research found that gas ducted central heating produced just one third of the emissions of heating produced by black coal-generated electricity. (Source: Assessment of Greenhouse Gas Emissions from Natural Gas, Australian Gas Association, 2000).
- When it gets really cold outside, reverse cycle systems lose efficiency, while Brivis ducted gas systems keep your home as warm as you want it – no matter how cold it gets outdoors!
- Ducted gas heating provides instant warmth that won’t dry out your eyes.
- Ducted gas heating heats your whole home – delivering lovely warm air through unobtrusive vents in the ceiling or floor.
- You get fingertip control – increasing or decreasing the temperature to suit you and your family.
The higher the star rating, the more efficient the heater. Ratings measure what percentage of gas used in the heating process is converted into heat. The higher the rating, the closer to 100% of the gas is being converted into heat.
How does ducted gas heating work?
A ducted gas heating system includes a number of essential components:
- The heater itself
- Insulated ducts that carry air from and to the heater
- Vents (also known as grilles or registers) that spread air into individual rooms and return air to the heater &
- A thermostat.
- Gas heaters work by passing cold air over a heat exchanger, which is warmed by gas combustion.
- The warmed air is then pushed through ducts into the home via a series of vents in the ceiling or floor.
- A thermostat is installed in the main living area. This senses the air temperature inside the home and sends a signal to the heater to cycle on, or off, to maintain the desired temperature.
- The products of combustion are all discharged safely outside the home, via a flue.
