Venting Hot Air Out Of A Metal Shed Any Ideas?

[Gazza2001au]

i need some help venting my shed i would like it to be vented out of the roof but i dont want one of those big bulky whirly bird things to sticking out the top of my shed but i really need the hot air from the sun hitting the roof vented i was looking at a little solar powered fan

heres the info

Solar Exhaust Vent Cat. 2598 BIAS Price $59.90

Exhausts up to 680 cubic feet per hour. Diameter 215mm.

do u think this fan will work for a 4.5 x 6.5 x 6 shed?

the grow chamber is already being vented out of the shed so this fan is only to cool down around the roof area of the shed

I can tell ya what not to use....one of those roof vents (the whirlies) unless your shed is surrounded by trees...

 

On my nightly cycle rides I can count the number of houses with sheds with weed in them...ie on a cold day their whirlies are going 1000 miles an hour while the ones on their house roofs arent...

 

If your only running a couple of lights Id use a whirlie but 8K watts setups really need other methods of ventilation

 

Try creating an artifical roof/ceiling inside your shed and sticking an extraction fan in that to push the air out......plant trees around your shed so the sun doesnt warm up the tin so much etc etc...

Oh yeh chuck some pink batts up on your new ceiling it helps a lot!

Never thought of that......... I think I better modify

my setup

Fossil its worse during winter as the rain kills the sourrounding smells and I can then smell it too...

 

BUT its really a case of those in the know...ie growers which are more likely to spot this...

im only using one 250hps that doesnt produce the heat its mainly the sun hitting the tin that really heats things up i was also thinking of those little whirly things on top of buses but ive been looking all over the net and cant seem to find any they are also found on utes with canopys and work vans do u think that solar power fan would be sufficient venting the hot air out?

also with those whirly things on the buses,utes,vans they have this circle thing on the inside that closes the hole great for winter ive been working on two buses that have these vent/fans the exhaust hole is about 80mm

does anyone know where i can get a vent online?

thanks

hey bro,

 

put some fibergalss insulation in the roof of the shed and the walls , im a builder by trade and would reccommend rockwool insulation by csr.

 

The differance will be huge!

 

cool in summer and warm in winter.

You can get thermal rated batts which are just as effective for heat insulation and are much cheaper than rockwool. I would only go to the expense of rockwool if sound insulation was important otherwise you are throwing away money for no good reason IMO.
