How does it work?

Evaporative cooling and gas ducted heating are two separate systems, but can both be placed under the same roof to provide heating and cooling. Please refer to the Gas Ducted Heating and Evaporative Cooling pages for more detailed information regarding each specific system.

Why have both systems?

The benefits of having both systems is that your house will have climate control year round (heating and cooling), without compromising on the quality of air coming into the house.

One Controller
You can have year round heating and cooling, typically using one controller –speak to our sales specialists for more details.

Energy Efficient

Evaporative coolers are one of the most efficient ways to cool your house as well as high rated (energy efficiency rating) gas heaters. With a combination of both, you are receiving the best heating and cooling option with the most value out of your investment.

Environmentally Friendly

Evaporative coolers do not contain any harmful refrigerants (unlike refrigerated air conditioning units), which means that the ozone layer is not harmed for the sake of your cooling needs. Some gas heaters are able to use natural gas which is a greener alternative to LPG.

How Does Gas Ducted Heating Work?

A ducted gas heating system is operated by drawing in air through a fan, and passed over to a heat exchanger to warm it. A return air vent (grille) recirculates air to the furnace, beginning the cycle again. The furnace (fueled by natural gas or LPG), which contains the heat exchanger, is usually installed in the roof space or just externally, but it can also be placed under the floor or even in internal cupboards if space is limited.

Ducting (which is connected to the heater/furnace) distributes the heated air throughout the home, and is usually hung/strapped within the ceiling space or under the floor.

Registers (also called ‘grille’, ‘outlets’ or ‘vents’), situated in the floor, ceiling, or sometimes the wall, 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.

How Does Evaporative Cooling Work?

Evaporative Cooling uses the natural cooling properties of water to lower the temperature of a room. A ducted cooling unit is installed on the roof and connected to a series of outlets placed throughout the home. The unit draws in fresh air from outside your house.

As the air passes through the filter pads (inside the roof unit), the air is cooled down and directed into every room in your house. The hotter the air, the better the cooling effect will be.

The entire volume of air within the house is refreshed every few minutes when using an Evaporative Cooler.

*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. House Heat load – 0.2 MJ/h/m3 – based on AS4556-2011 • Annual Energy Consumption (AEC) for different star rated heaters based on AS4556-2011. 3.0, 4.0, 5.0, 6.0 star rated ducted gas heating systems.

In comparison to traditional heating systems, gas ducted heating uses less electricity, and produces substantially less Greenhouse Gases. So not only will you save on running costs, but there is substantially greater environmental benefits for using gas ducted heating as well.

With Braemar gas ducted heaters you can save on average 0.69T – 1.99T of C02 emissions per year – while also enjoying a comfortable warm home.

What Are The Running Costs With Evaporative Cooling?

Our commended Evaporative Cooling manufacture Breezair has the highest rating and reduction of running costs across all Evaporative Cooling brands here in Australia. Breezair Evaporative Coolers are so efficient they cost less than one tenth of a standard ducted air conditioner to run.

You could enjoy a comfortable cool house during the summer and other hot days of the year for as little as $37 per year in eletricity costs*. When you do the math,that’s on average $346 per year of savings in electricity costs compared to a standard effciency ducted refrigerated systems

In comparison to traditional refrigerated airconditioning systems, evaporative cooling uses less electricity, has a lower peak energy usage, doesn’t produce CFCs or HFCs, and produces substainally less Greenhouse Gases. So not only will you save on running costs, but there is substainally greater environmental benefits for using evaporative cooling as well.

    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.
