Whirlybirds v Solar vents
Do whirlybirds work? Lucky for people who live in Perth, one of the windiest cities in the world they will work there best on a windy day! I’ve been installing roof vents for over 10 years and of course they remove the Heat. On a 35 degrees day when I walk onto a roof and cut a hole, well the amount of heat to come out is like a hair dryer working on full speed, so they will work but the question is now, what works better! The whirlybird? Or the solar vent?
Whirlybird Roof Vents
Advantages for the Whirlybirds
- The Whirlybird will work 24 hours a Day and the solar vent will only work 10 hours per day.
- The Edmonds Whirlybird comes with a 15 year warranty and solar vents only has a 5 year warranty.
- A Whirlybird will only cost you one quarter of the price as a solar vent.
- Whirlybirds don’t make any noise! Unless there 20 years old and need to be replaced.
- Whirlybirds come in a range of colours, solar vent only comes in Black.

Disadvantages with the whirlybirds
- Whirlybirds need wind to work better and remove more heat

Solar Powered Roofing Vents
Advantages for Solar Vents
- Solar vents take out 5 to 10 times more air then the whirlybird. (Eco solar vent)
- On the hottest days when there’s no wind! Full sun! The solar vent works 100%
- On flat roofs with no heat convection (heat rising) the solar vent will suck the heat out.
- Solar vents have a built in thermostat, so they turn off in winter. (keeps the Heat in)
- Solar vent is better value for money. Cost more but removes more heat.
- With the thermostat it uses the brushless motor less, will last twice as long (15 years)
- Solar vents will save you money on air conditioning cost
Disadvantages with the solar vent
- The solar vent will make a little bit of noise. If your listen you could hear it?
