How Does Ducted Gas Heating Work?

Scandia has been installing gas ducted heating in the Canberra region for over 25 years. Once considered a luxury gas ducted heating is by far the way the most common form of whole of home heating, chosen by Canberra residents.

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; and

• 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.

Installation Options

There are three options when installing ducted heating, you can install the heater in the roof, under the floor, or outside the house, with ducts in the ceiling or under the floor.

However the location of the heater largely depends on your homes construction, if your house is constructed on a concrete slab the heater will be installed in the roof with ceiling registers than can be either round or square. If your home sits on floor joists the heater can be located externally or under floor depending on the space available.
