Ducted Gas Heating


Ducted gas heating is the most efficient way to heat your entire home. The main unit is located in the roof, which is then connected to ducts to provide heating to the rooms of your home.  Gas heating is also considered to be a more natural way of heating, reducing environmentally damaging emissions compared to other forms of heating.

Pairing ducted gas heating with evaporative cooling is one of the most energy efficient ways to warm your house in the winter and to cool it in the summer.

Who should use a ducted gas system?


A ducted gas system is great for anyone looking for a cost and energy-efficient way to heat their home, while also reducing their environmental impact. A ducted gas system is also an ideal solution if you already have an evaporative cooling system, and if you have the ceiling space required for for the unit.

What are the upfront and ongoing costs associated with running a ducted gas system?


The purchase and installation of a ducted gas system could cost anywhere from $3,500 - $7,500+, depending on the size of the unit, zoning requirements, and the configuration of your home.

Gas systems can be relatively cheap to run, costing anywhere from $350-$1,150/year, depending on usage and the size of your home.

Reducing the cost of running a ducted gas system


To reduce the cost of running a ducted gas system there are a number of things to consider.

Firstly, consider adding zones to your system. This allows you to pick and choose which rooms you want to target, without having to pay to heat the whole house.

Secondly, consider ceiling insulation. Insulation prevents heat from escaping through the roof in winter, and stops it from entering in summer. This means you could potentially buy a lower-powered unit and also save on energy bills, as your heater doesn’t have to work as hard.

Third, remember to keep everything closed! Open doors and windows allow heat to escape, which means your system will be working overtime to keep things at temperature. Even closing the curtains and blinds or adding a ‘door snake’ can make a big difference to heat retention.

Finally, consider adding solar. While the sun can be fairly scarce on those colder days, any bit of sunlight helps to offset the cost. And even if your heating costs are still quite high, solar can reduce your overall energy spend across the year.
