I had roof insulation installed soon after my house was built. The deal included a whirlybird but for some reason there was a delay on this. Many phone calls later the whirlybird finally arrived, on a warm summers day. I was not at home at the time but two of my teenage sons were and they noticed a considerable drop in the temperature inside the house once the installation had taken place. So, in my opinion, they do work.

Have a look at Superflow ventilators $125.00

They have a simpler fan than the twister above

Just on a side note, I went for the whirly birds with the clear perspex vent to allow light into my ceiling, my theory was that the light within the roof would help keep vermon out and also assist me when i have to get into the roof space.

Now they have skylights that are self ventilating.

So the balance is- do you want a skylight that ventilates? Or a vent that lets in light?

What of the whirly birds with the driven fan blade.. i wonder if they work better.

Now consider the other finding the a signifucant PV array shades the roof and some have reported with significant impact on roof space temperatures..

Im with the thought the no ventilation is better in winter..
