Whirlybirds or Solar Exhaust Fans? Solar is the Answer!
DOMESTIC ROOF VENTILATION
Living in Brisbane and most of Queensland means that even in winter the days can be hot. On any given day roof temperatures can often reach temperatures of 70 degrees. This scorching roof temperature causes a real struggle when it comes to cooling your home without exuberant electricity costs. Although ceiling insulation does somewhat help it does not give you the comfort you need to live comfortable in the Queensland climate.
ROOF VENTILATION WITH EXHAUST FANS – THE KEY
The key to comfortable living in Brisbane and the rest of Queensland is effective roof ventilation. Adequate roof ventilation requires effective extraction fans or roof vents. People in Brisbane have for decades been installing whirlybirds as roof vents. If you are not sure what whirlybirds look like next time you are out about – there are whirlybirds on a very large part of the roofs around Brisbane. The question which more and more people ask themselves is:
ARE WHIRLYBIRDS ROOF VENTILATORS THE MOST EFFECTIVE WAY TO ENSURE GOOD ROOF VENTILATION?
Over the last few years solar roof ventilation has come from being fringe technology to main stream. Whilst solar roof ventilation has been around a long time things started changing throughout Australia, not least in Brisbane and Queensland when Solar Whiz was introduced in 2010. If you want to know more about Whirlybirds vs Solar Roof Ventilation – there is lively debate on forums like the ATA Alternative Technology Association and the Roof Ventilation Blog has articles about whirlybirds roof ventilators and roof ventilation in general as well as comparisons of solar exhaust fans vs wind driven roof ventilators.
SOLAR WHIZ EXHAUSTS FANS & ROOF VENTS
Solar Whiz exhaust fans not only extract the hot air out of your roof but also replace the hot air with fresh air from outside to create a natural airflow through the roof space.
WHIRLYBIRDS ROOF VENTILATORS – HOW DO THEY WORK?
Roof ventilation with whirlybirds roof ventilators requires the roof to heat up in order for the whirlybirds roof vents to start operating. We all know that hot air rises, but it also expands – in all directions. If you have roof vents in your roof space they will let warm air out. –It is the expansion of the air trapped in the roof space that makes whirlybirds spin.
On windy days the design of whirlybirds also helps them spin and therefore act as exhaust fans. However the flow rate on a whirlybird in comparison to a Solar Whiz is very low.
WHEN DOES THE SOLAR WHIZ ROOF VENT WORK?
Solar Whiz roof extraction fans start working the moment the there is enough light to start the fan motor which prevents the heat from building up in your roof space – and therefore from penetrating your ceiling and heating up your house.
If you already have a ducted Air Conditioning system you will notice a dramatic improvement in efficiency – when installing solar roof ventilation. And not only that – you will also find that you can reduce the running time of your A/C significantly after installing a Solar Whiz.
The Solar Whiz – More effective than 15 roof ventilation Whirlybirds
The Solar Whiz roof vent works like a super Whirly-Bird. The Solar Whiz comprises of a solar panel, powering a fan, which extracts the hot air out of your roof 15 times faster and more efficient than traditional whirlybirds.
Queensland is not short of sunshine, which is why solar roof ventilation is such an untapped resource. Solar Whiz cuts your cooling costs considerably by tapping into this natural resource.
