Ducted Gas Heating

Is Ducted Gas Heating The Best Solution For Your Home?

What is Ducted Gas Heating?

Ducted Gas Heating is a system designed to heat an entire home effectively by using one central gas heater. Connected to a series of ducts, the heater draws the cold air from inside the house through a Return Air Grille, heats it by passing it through its heat exchange, and then distributes the warm air out to each outlet through a chain of ducts. Vents (or outlets) are strategically placed to ensure all areas throughout the home are heated evenly. Adding zones to the heating system will allow the flexibility for the user to heat only the rooms which are being utilised. Due to its low running cost, Ducted Gas Heating is the most preferred option in Melbourne for whole home heating.

What Is Ducted Gas Heating

Why Choose Gas Ducted Heating?

Cost Effective

Gas Ducted Heating comes with a low supplied and installed cost when compared to ducted refrigeration options, making Gas Ducted heating a feasible option.

Low Operational Costs

Natural Gas is cheaper than Electricity in Australia, making these units much more cost effective. The main ongoing cost is the General Service which is recommended to be carried out at least every two years.


When installing a Ducted gas heating system, the heater and its ducts are concealed either in the roof space or under the floor with the outlets positioned to blend in with the ceiling or flooring.


Compared to the bigger Ducted Refrigeration units, heaters are much quieter. The main noise is the heater's fan and the air being drawn in through the Return Air Grille.

Zoning Options

Because Ducted heating uses one central heater to heat the entire house, most models come with zoning capability. This option allows the duct to the unused areas to be closed off from heating. This is similar to having portable gas heaters in every room, except you are using one unit.

Star Rating  

Each heater nowadays comes with Star-Ratings. This reflects the efficiency of the unit and illustrates the amount of Energy Consumption of the gas ducted heating system. Choosing a higher star rating raises the upfront cost but lowers the running cost, making a higher star heater a viable long-term investment.

What are the Running Costs of Gas Ducted Heating?

Gas Ducted Heating is the preferred option when it comes to heating an entire home, primarily due to its low annual running cost. Even the 3-Star ducted gas heating cost is more efficient than most other heating units such as electric heaters and heating using Split System Air Conditioning units. A higher efficient heater can further reduce the running costs by up to 30% per year.

According to Sustainability Victoria, it is estimated that heating an entire 170 square metre home will cost on average $970 per year. Zoning will dramatically reduce the cost by $240.

How Much Is Gas Ducted Heating?

Gas Ducted Heating Costs

Gas Ducted Heating prices generally varies anywhere between $3,050-$5,500 for a typical 3-bedroom house, depending on the capacity of the unit and its star-rating. Additional features such as zoning, extra outlets and controller upgrades all contribute to the actual ducted heating installation cost.

A final quote is unique to each home due to contributing factors such as the size and configuration of the house, the position of the heating unit and distance to each outlet, the access in the roof or under the floor, ceiling heights, window coverings.

Ducted Heating Maintenance Costs

Just like a car, central heating systems also requires ongoing service and maintenance costs. It is recommended that all ducted heating units be serviced once every two years, although, with the Carbon Monoxide threat, we highly recommend a service with a carbon monoxide test to be carried out every year before Winter.

With the average cost being around $240 per service, the amount spent is a tiny investment for the safety of your home.

Ducted Reverse Cycle Vs Ducted Gas Heating

Because Ducted Reverse Cycle Systems also cools, we can not compare apples with apples when putting it up against Gas Ducted Heating. A Gas Ducted Heater with Add-On Cooling, however, is comparable.

Both a Ducted Reverse Cycle Systems and Gas Ducted Heating with Add-on cooling will cost anywhere between $8,000-$15,000

This example is based on a Brivis 6-Star Heater with a 30kw capacity + 17kw Add-On Cooler compared to a Mitsubishi 17kw Ducted Reverse Cycle System

What Customers are Saying

“We had 2 split systems installed just over 2 years ago and have since had 2 service calls. We could not be happier with the service we have received from Plum. The servicemen have gone about their work with little fuss, explaining what they were doing and cleaning up after each unit was serviced. This morning Shiva was here, and he was very courteous as he was working. We have nothing but praise for Plum”

"Helpful and friendly team. We had to change the date and time of the install last minute and were greeted with a ‘no problems and happy to fit in with you’ attitude. The installers arrived on time. They were friendly and respectful. They were in and then out in no time and cleaned up after themselves. They even returned things they had moved back to their original spot. Very happy we went with Plum"
