What is Gas Ducted Heating?

Gas ducted heating is a ducted system installed in your roof space or under your floor, depending on the space available. It uses gas to produce heat, which is distributed throughout your whole home through a series of ducts and vents.

Ducted gas heating is one of the most popular heating systems used in Melbourne.

Coldflow can help with a new or replacement ducted heater, as well as servicing and repairs for your existing heater.

Choosing Gas Ducted Heating as your Home Heating System

Gas ducted heating is an excellent option for Melbourne homes, especially through the colder months when temperatures drop sharply. The system uses natural gas to warm the air in the ducts, which then circulates through vents in each room.

One of its main advantages is efficiency. Gas is a highly efficient fuel source, so the system heats a home quickly and effectively, which can mean lower energy bills and a reduced carbon footprint compared with other heating options.

Gas Ducted Heating Benefits

Gas ducted heating is also flexible. Depending on your installation, you can control the temperature of each room individually, which increases comfort and reduces energy waste.

It is known for reliability and low maintenance. Once installed, the system needs minimal upkeep and can last for many years with proper care.

For Melbourne residents, gas ducted heating is a smart choice: cost-effective, efficient, and a reliable source of warmth through the colder months.

Frequently Asked Questions About Gas Ducted Heating

How does Gas Ducted Heating Work?

A ducted gas heating system is operated by passing cold air over a heat exchanger; the air is then warmed through gas combustion & then distributed and pushed throughout the home via a series of ducts, with connecting vents in the ceiling or floor.

Registers (also called grilles, outlets or vents), in the floor or ceiling, direct warm air into rooms. Heating outlets are best placed around the perimeter of the house, providing even heat distribution throughout your home.

What are the running costs with gas ducted heating?

Our recommended gas ducted heating manufacturer, Braemar, has the highest rating and the greatest reduction in running costs across gas ducted heating brands in Australia. Braemar carries energy star ratings of 3, 4, 5, 6, and a 7 star equivalent that is exclusive to Braemar. (The 7 star rating equivalent is based on the Australian Gas Association's results, calculated in accordance with the testing methodology in AS4556-2011.)

Using a Braemar gas ducted heater you can save on average $198 to $577 a year on running costs, depending on the unit installed.

Gas ducted heating also uses less electricity and produces substantially fewer greenhouse gases than traditional heating systems, so you save on running costs and gain a substantial environmental benefit at the same time.

With Braemar gas ducted heaters you can save on average 0.69 to 1.99 tonnes of CO2 emissions per year, and enjoy a comfortably warm home.

*Data is based on: • Gas price = 1.6 c/MJ • House Size – 241 m2 x 2.4 m ceiling height • Operation hours per year • 600 hrs(100 days at 6 hrs per day) – based on AS4556-2011.

We would have liked to be given the option whether to have the smelly chemicals sprayed in the split systems, as the smell lasted for over a week and we would have opted not to have that. Otherwise we are very happy with the overall service and communication from the technician.

I have always had very good service from Coldflow in the past and now at present and I would thoroughly recommend them to everyone who has airconditioning. As our house is relatively new at present, we are waiting to hear from the builders if our system is still under warranty, if it isnt we will certainly get back to you again.

All went well. I have had the heater on today and it is working as expected. The inside unit is very quiet and the outside section, which is just outside from where I sit, is unnoticeable. After having a listen outside I am convinced my neighbours will not hear any residual noise at all. The remote control is easy to use.
