Why SolarKing roof exhaust fans are perfect for your Australian home.
SolarKing roof exhaust fans are proudly built in Australia and designed to tackle those harsh summer days when your roof space can soar past 70ºC – turning your home into a giant oven. But while your air conditioner works hard to cool the inside of your home, that relentless heat from above never lets up, forcing your system to run harder and longer.
That’s where a SolarKing roof exhaust fan makes the difference. As soon as your roof space hits 25ºC, the fan automatically switches on, extracting the trapped hot air, while drawing in cooler air from outside. With more than 20x the airflow of a standard whirlybird, it quickly reduces your roof space temperature and in turn, helps keep your whole home cooler.
So what’s this all mean?
Well, we’re glad you asked – it means your home stays cooler, which helps your air conditioner run more efficiently, with less strain and lower running costs. Also because SolarKing roof exhaust fans are completely solar powered, it won’t cost you a cent to operate – ever.
FAQs
We offer SolarKing roof exhaust fans as an optional add-on with all our air conditioning installation quotes. While the exact price can vary depending on installation requirements, for a standard Australian home you can expect installation to be around $650.00 when added alongside a new air conditioning system.
Absolutely – you don’t need to install an air conditioning system to benefit from a SolarKing roof exhaust fan. Many homeowners choose to install an exhaust fan on its own to help keep their roof space cooler and make their home more comfortable during summer.
Not at all. The SolarKing roof exhaust fan only activates when your roof space temperature reaches 25ºC or higher. This means it works to keep your roof space cooler in summer, but stays off during the cooler months – so it won’t remove the warmth in winter.
It’s a simple, smart and effective solution for Australia’s climate.
In most cases, the SolarKing roof exhaust fan can be installed in place of your existing whirlybird. Our installers simply remove the old unit and fit the SolarKing into the same opening, giving you a far more powerful and efficient solution with over 20x the airflow of a standard whirlybird.
If your whirlybird position isn’t ideal, we can also install the SolarKing roof exhaust fan in a new location to maximise its performance.
Yes and yes. The SolarKing roof exhaust fan is perfect for homes, sheds and garages. As long as the sun can power it, it’ll work to keep your space comfortable.
