Wondering what everyone’s opinion is on wind powered whirlybird and solar vents.

What area of vent for one fan? Interesting that there's no answer to this question on here or directly via the suppliers website. Inlet vent area will be critical to the performance of the fan and yet there's no info available????? Re: Whirly bird or solar roof ventilation 9Mar 30, 2019 7:17 pm I have a full length ridge vent.

Re: Whirly bird or solar roof ventilation 10Jan 08, 2020 6:00 am I had an extraction fan (non solar) in my old house and air was the best $400 I spent. I had the thermostat set to 28°. Whirly birds for me are counter productive as they work all year round. Hot air rises and shoot out those vents. In my opinion that’s the last thing I want in winter. I regularly drive past homes on cold days and see them spinning away on people’s roofs. I bet they probably have their air con going to warm the house. Why expel valuable free warm air in your roof when it could be there warming your home. Just my opinion.
