Gas Heating

Gas heating systems can be fuelled by either natural gas or propane with simple modifications accounting for the different characteristics of each. We refer to both fuels as simply "gas".

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.

Why gas heating?

In most areas, electricity costs are rising faster than gas, so natural gas heating offers a cost-effective alternative.

Natural gas is also 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 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.
