What is Gas Ducted Heating?

Gas Ducted Heating is a ducted heating system that is situated either in your roof or under your floor (depending on available space for the system). As the name suggests, it uses gas to produce heat which is then distributed through your home.

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’), situated in the floor or ceiling, direct warm air into rooms. Heating outlets are best placed around the perimeter of the house, to provide an even heat distribution throughout your home.

Why Choose Gas Ducted Heating?

Gas Ducted Heating is the most popular method of heating in Melbourne, as the efficiency of heat output is not dependent on the outside temperature (unlike Reverse Cycle Heating Systems).

Save on Gas Ducted Heating Running Costs With Zone Control
Zone Control or Zoning may also be introduced to further reduce the running costs of a Ducted Heating system, as it allows you to choose the areas/rooms of the house you wish heat or cool.

Add-On Cooling Available
With Gas Ducted Heating, there is the option to have Add-On Cooling installed. This will provide cool refrigerated air conditioning throughout the same vents that your Gas Ducted Heater uses, saving space & money, as your roof will only need 1 set of duct installed to provide both heating and cooling throughout your home.

What Our Customers Are Saying
  • we would recommend Cold Flow to anyone who is looking to replace their old ducted heating...
    Overall, we are very happy with our new ducted heating system. Our home is much warmer and it's a conformable, even temperature. Our sales consultant from Cold Flow was professional, friendly and helpful and he assisted us in finding the right system for our needs. On the day of installation, everything went smoothly. The technicians arrived on time and the job was completed in a timely manner. We did experience a small issue with electrical work, but this was sorted out for us quickly. We also recently had an issue that required us to call on the warranty area at Cold Flow and this experience overall was positive. In summary, we would recommend Cold Flow to anyone who is looking to replace their old ducted heating system, as we did, or install a new one.

  • Will recommend to anyone who is looking for a trustworthy company...
    Before the winter we decided to change the heating unit. They promptly send someone over to give us a quote. Alvin was very honest, explained in detail and recommend something suitable for us unlike other sales from other quote I get just trying to push for expensive unit to change over. The guys came and installed in very professional way. Even after installation I had a tiny query about the unit, they even send someone over just to help me solve the problem. They care about people's review which means they care about their business and how their guys perform. Will recommend to anyone who is looking for a trustworthy company.

  • I had a perfect experience when installed a ducted heating system with ColdFlow...
    I had a perfect experience when installed a ducted heating system with ColdFlow. The 5 stars I gave include: 1. Salesman was honest and truly helpful in guiding me to choose the right system. 2. Still him, he came to inspect and gave the best price I could find. 3. The woman organizing installation time was really kind to arrange the best time for us which was actually not convenient for them 4. The technicians came and wait 2 hours just only for our convenience. I deeply appreciated their patience and kindness. 5. The installation was completely professional: careful, timely, nice, neat and tidy after finish. What else could I request?!

  • Coldflow were able to work out my problems with heating and cooling...
    I am very pleased with Coldflow, after being mucked around by another provider that could not provide what i wanted. Coldflow were able to work out my problems with heating and cooling. Installed a new Braemar gas ducted heating, - and good thing it is all set up for summer (larger ducts etc.)- when i want to add the cooling. We had one minor mis communication when we got on site, but the their engineer sorted it out over the phone, so overall- no complaints, overall, very happy, thanks Mag

  • Highly recommended, will be calling them again close to summer to fix our cooling needs...
    Electric heaters were just not cutting it. High electricity bills not helping the family budget, we decided to go with gas ducted heating. Cold flow had a solid rep so we went with them and were not dissappointed. Punctual, efficient and very polite. Was able to negotiate a good price on the unit and installation which was another bonus. Highly recommended, will be calling them again close to summer to fix our cooling needs.
