How it works

Whirlyvent Roof Mounted mechanical ventilation

Like traditional attic fans, the Whirlyvent solar roof exhaust fan removes hot, stagnant air from your roof space and allows your air conditioner to more efficiently cool the house. What makes our solar fan even better is that it requires no public electricity, that means not only are the attic fan's operational costs zero but your installation works are easier. Our solar fans blend seamlessly into your roofline and are extremely quiet, if it wasn't for the energy savings, you might forget they are there.

With summer just around the corner, most people are looking for options to cool their home. Roof ventilation has always been a popular option but what products are best for my home and how do I know it will help?

Firstly, roof ventilation should not be considered for only cooling your home, its most important feature is creating a healthy roof cavity. By having roof ventilation, not only do you cool your roof cavity, but you also remove moisture that causes most roof cavity issues, such as ceiling mould, wood rot and a habitable living space for all your creepy crawlies.

Will roof ventilation work on my home?

The simple answer is YES. The process of roof ventilation is all about how much hot air is trapped inside your roof cavity and how quickly you can exchange with cool air from outside the home. Every home has an element of "trapped" hot air. Remember it will also help with all those moisture issues above.

How much will it cool my home and how many do I need?

While the air outside your home may be 30 degrees, your roof cavity can reach up to 50-60 degrees. By removing this hot air, you can have a dramatic effect on the temperature inside your home.

There are a lot of different variables when ventilating your roof cavity, which is why manufacturers struggle to provide how much their product will lower the temperature of your home. The more hot air trapped in your roof, the more difference roof ventilation will make on your home.

The third and final question is "which product should I choose?"

The third and final question is “which product should I choose?”

  1. Effectiveness – exchanging the hot air within your roof cavity with air from outside is the most important element. This makes the airflow of your roof ventilator most important. So do I choose a wind vent or solar powered mechanical vent?
    1. Most mechanical ventilation will typically extract more air than 15 standard wind vents.
    2. Mechanical ventilation will still operate on hot days when there is no wind.
  2. Life span – with many imports entering Australia, longevity is becoming more of an issue. While many manufacturers offer long warranties, many also have exclusions on motors. Make sure you look at the warranty across the whole products particularly on the motors. The difference is usually in the type of motor. Brush motors usually require the brushes replaced every couple of years. Brushless motors will tend to last longer often receiving a longer warranty period.
  3. Aesthetic – how will our solar power roof ventilation blend in with your roof.

    How the product looks on a roof will vary from person to person, especially if it’s on the front side of the home. The value of roof ventilation should be assessed on the amount of airflow, longevity of the product and the price.

Installation options

  1. Whirlyvent cools the roof space by installing eave vents around the house, the roof fan creates a cross flow of air at the desired air changes which reduces the temperature of the house.
  2. Whirlyvent cools the room directly by installing ducting down to the room from the roof fan. This creates a cross flow of air in the room at the desired air changes which reduces the temperature of the room directly.
  3. Whirlyvent cools several rooms directly by installing multiple ducting’s down to the rooms from the roof fan. This creates a cross flow of air in the room at the desired air changes which reduces the temperature of the room directly.
