Has anyone heard about a solar attic/roof fan?

[Katymac]

'cos it might be a way to cool my conservatory

Will ask my dh. He knows about all this stuff.

Please do Pierre

I would appreciate

Nope, you need a swamp cooler for your conservatory. Solar Attic Fans are to cool down the hot air that accumulates in your attic, their big and run using solar power. We're going to have one installed here in the house (we're in Colorado and it's constantly 100 in the attic 38 c.

Swamp coolers use water and a fan and push chilled water around, very cheap to run and very very effective. Combined with blinds I would say that would work. Oh and they're called evaporative coolers incase the UK's not heard of swamp coolers.

They are awfully big Alipiggie - and they certainly can't be fitted into a wall (which is my big hope)

Don't they sell small ones, they do over here? Solar attic fans are big too, but maybe they have something similar for conservatories, don't know. You could always get just a simple roof fan - b&q sell them, with light attached, that would have the same effect and it's much smaller.

My conservatory is a lean-to so no ceiling fans

I wanted a solar fan so it didn't cost me anything

Maybe something like this would be okay, designe for boats, but perhaps could be adapted for your conservatory. see this

That would take 4 hours for a single air change

I'd need about 2 air changes an hour which would be 8 of those

Oh poo

Thanks for the idea tho'

I was thinking about this gable end fan?

here

Solartube /solarstar are great some of the best. They're very very effective, for our huge attic we should only need one large one. I guess for me it would be how big is it. But what a great idea you had. Can you source one easily enough??

That company has a branch in this country

I was hoping it would remove "superhot" air and encourage a draft?

have you heard about his one, found it whilst googling don't know what it would be like though

I am a bit worried about turning it off in the winter (I need all the warm air I can get then)

I'll ask my h about the attic fan and how it works he's back from trip today, but will post as soon as I can. AS for the other thing it looks as though it helps retain heat in the winter. Umm quandry isn't it. Let me look into it some more and I'll post soon Katymac promise.

this looks good but so expensive

I'd need about 88 linear metres of it at nearly £15 a metre
