Using Whirlybirds and Solar Vents to Reduce Heat in Your Home

During the summertime in Australia, many of us will be looking for ways to keep our homes cool without breaking the bank. The temperatures inside the roof cavity can reach up to 70 degrees Celsius (158 degrees Fahrenheit) or higher. This can lead to a considerable increase in energy bills, as air conditioning units have to work harder to keep the house cool. Additionally, the increased heat can make the living spaces in the home uncomfortable, which can detract from the overall quality of life.

To combat this issue, many homeowners turn to whirlybirds or solar-powered extractor fans.  These devices effectively ventilate hot air out of the home and bring in cooler air from outside. By doing so, the temperature in the roof cavity can be significantly reduced, making living spaces more comfortable and reducing the need for air conditioning.

Using whirlybirds and solar vents is particularly beneficial in areas where electricity prices are high, as it can help homeowners save money on their energy bills. Furthermore, these devices don’t require any electricity to operate, meaning that they produce zero greenhouse gas emissions. This can help reduce carbon footprint and make the home more sustainable.

These devices work by ventilating hot air out of your home and bringing in cooler air from outside. In this blog post, we will discuss the benefits of using whirlybirds and solar vents, as well as how to install them in your home.

How to Install Whirlybirds and Solar Vents

Installing whirlybirds and solar vents in your home is a relatively simple task that can be completed by most DIY enthusiasts. To install a whirlybird, you will need to locate the position on your roof where the whirlybird will be most effective. This is usually the highest point on your roof, as hot air rises. You will then need to remove a section of the roof tiles or sheets, and install the whirlybird in its place.

Solar vents are similarly easy to install. They are typically mounted on the roof of your home, and can be connected to a solar panel or battery for power. Once installed, they will begin to ventilate hot air out of your home, and bring in cooler air from outside.

It’s important to note that while installing whirlybirds and solar vents can be done by most DIY enthusiasts, it’s always best to consult with a professional if you are unsure about any aspect of the installation process.


Whirlybirds and solar vents are a highly effective way to reduce heat in your home, while also saving money on your energy bills and reducing your carbon footprint. With a little DIY knowledge, you can easily install these devices yourself and enjoy the benefits of a cooler, more comfortable home. So why not give it a go and see how much you can save this summer?

Remember to always prioritize safety and consult with a professional if you have any concerns about the installation process. By using whirlybirds and solar vents in your home, you can improve your living environment, save money, and help to protect the planet.
