ducted central heating with Brivis gas systems
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 your needs.

what is it?
Ducted central heating comprises a gas heating unit, which is connected to a series of outlets. Positioned strategically throughout your home, these outlets, or ducts, are installed within in the floor or ceiling. Installation of the heating unit depends on your home. If you 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 ductwork, which connects the outlets to the heating unit, is neatly tucked away out of sight.

how does it work?
The heating unit draws air from inside your house into a filtered return air grille. From here it then flows into the heater where it’s warmed, and then distributed to every room of your home via outlets, in the form of warm, gentle air.

It may surprise many Canberrans that ActewAGL says using the latest electric reverse-cycle heater in a three bedroom home for 10 hours a day throughout winter costs $460. This equates to about 50c per hour. The utility company says using natural gas ducted heating for 10 hours a day throughout winter would cost $874, or 95c an hour. Both these calculations assume that the heating runs for 50 per cent of the time.
