Benefits of CW3 Dual System

Delivers unrivalled efficiency

The ultimate in sustainable living.

The CW3 offers two options: either as a combined heating and cooling system or as a stand-alone hyper-efficient cooling only solution; both for home owners wanting next level energy-efficiency and superbly functional design. Using an indirect evaporative counter-flow heat exchange core to provide hyper-efficient cooling of outside air, the CW3 offers greatly reduced energy consumption compared to equivalent refrigerated systems and delivers 100% fresh air.

When it becomes paired with a gas heating unit located in the roof space, the CW3 Dual System is also able to deliver warm air through the same ducts and goes into the home via the same small vents in the ceiling – making the system much less visible and more cost effective to run.

The world's most advanced dual system

Heats and cools entire homes with temperatures comparable to reverse cycle.

Unmatched energy cost savings

Up to 60% reduction in energy costs compared to reverse cycle for total heating and cooling1.

Perfect balance of
air moisture

Operates effectively in
humid and dry climates, providing constant comfortable air.


Heating uses natural gas.
Cooling uses water and supplies 100% fresh air.


Whole of home. One set of ducts.
One set of ceiling vents. One controller.

365 days of comfort.

Cool your home effortlessly

The CW3 uses Micro-Core™ technology to deliver hyper-efficient cooling at incredibly low temperatures, comparable to reverse cycle systems. The outdoor unit is positioned on the roof, delivering cool air through ducts into the home via small vents in the ceiling. Warm air is expelled out of the home through a return air vent into the ceiling, and is released through the roof space, or, alternatively, windows and doors can be opened to release the warm air – it’s your choice. For cooling only, CW3 delivers up to 80% reduction in energy costs compared to ducted reverse cycle1.

The cooling system replaces the air inside your home with 100% fresh, healthy, filtered cool air 8 times an hour.

Micro-CoreTM heat exchange technology. The secret to hyper-efficient cooling.

  1. The outdoor unit is positioned on the roof, delivering cool, fresh air through ducts into the home via small vents in the ceiling.
  2. Warm air and any airborne particles are expelled out of the home through a return air vent into the ceiling, and is released to the atmosphere through the roof space, which means you can activate the system remotely while the house remains locked up.  Alternatively, windows and doors can be opened to release the warm air and particles – it’s your choice.
  3. The cooling system replaces the air inside your home with 100% fresh cool air up to 8 times an hour.
  4. Micro-Core™ cooling. Made up of the primary heat exchanger and secondary cooling stage to deliver cool temperatures equivalent or better than refrigerated reverse cycle at a fraction of the cost.

Harness the power of Safer-AirTM

Australians spend between 80 to 100% of their time indoors, either at work or at home2, which demonstrates how important Indoor Air Quality (IAQ) is. Exposure to poor air quality for extended periods can lead to severe health problems.

IAQ and ventilation is a high priority for buildings and work spaces under the building code, so it should also be taken seriously in the home environment, especially as it relates to the health and comfort of you and your family!

Heats your whole home

The CW3 Dual System heats your home quickly and efficiently with gas, providing instant cosy warmth. Ducted gas heating is the easiest, most comfortable way to heat your entire home, and is the ultimate in comfort, safety, reliability and energy efficiency. The gas heating indoor unit is positioned within the roof space. Warm air is delivered through the same ducts, and into the home via the same small vents in the ceiling as the cooling to make it a fully integrated system. A range of star efficiency options are available to choose from.

The future of home heating

Gas has a future, and that future is clean and green.

The answer is embracing the transition from natural gas to green hydrogen or renewable gas like biomethane. Using the infrastructure and appliances we already have, in a cleaner, greener way. This is a transition already under way in Australia.

Vogue Constructions (Canberra, ACT)

Andrew Boyne – Western Architecture Studio
(Perth, WA)

With increased extreme heat events in Perth, an air conditioning system was a necessary addition to  our low-energy house. The climate wizard is the perfect solution. We are able to keep indoor air temperatures around 23 degrees on 40+ days, while using no more energy than a TV, and because the unit doesn’t need to recirculate, we get this performance with only 100% fresh air, and even while keeping our windows open.

The assembly of the unit is ingenious. It can be broken down into components for easy service with only clips bands. Not a single screw needs to be removed.

We couldn’t be happier with the CW-3. It has made out house pleasant to live in and healthier to occupy. Combined with solar panels, we never have to worry about the financial or environmental costs of cooling the house. It is an amazing piece of technology.
