Hello baby bud

That exactly what im thinking of doing at the moment!! ive got a TT125 fan rigged up to Aqusitic ducting, pulling fresh air thought a vent in the top of my wall.

At the moment my 2 exhust fans are just going into the room where my tents are, if i shut the door, and go out, when i come back in the room if fucking hot mate !!!

thinking about cutting a hole in the wall ( back off chimney ) exhusting all hot air up the chimney.

ive spoke to my mate about this to great lenghts, an he tinks aslong as i board up the fire place, im fine.

because im in a flat other people might use there fires ( because of the hole i might carbon monoxide posioning ???) SCOUSE

Thats my only consene monixde posining, any 1 else think its a good idea ???

if other people are using the chimney, then that sounds dangerous. boarding up the chimney may not ne neccessary. just a load of semi inflated bin bags/trash bags wedged up there could do it.

Fortunately i have a vent already at the top of mine so would only need to hook up 2 ducting me thinks?

Am on the bottom flat, there is only 1 other person above me !

my understanding of phyisics ( not much ) is that if fans are blowing into the chimney, the hot air will rise, there fore taking any other air ( carbon monoxide ) up out of the roof ?????? so no carbon will come down to my level ? SCOUSE

and if's windy the air tends to be drawn up easier. But on hot, still day there might be a risk of stink coming down the fireplace

This i never thought of , so i should use the chimney vent for drawing air in & wall vent for extraction ? Or would i still get a problem?

Hi boys.
Each fire will have it's own chimney as gas appliances can't share a flue.
I would strongly advise agaist anyone using a chimney for extraction or intake unless u ensure there is no appliance attached to the flue/chimney. Also carry out a smoke test to make sure that the inner Walls which attach to the next chimney are in tack and not passing threw to urs as u could pull products from next doors fire into ur house.

But if you use expanding foam around your carbon filter for the chimney outtake, there would be no risk of pulling anything in???

If u can make for sure that the chimneys don't communicate with each other (smoke pellet in ur boarded up fireplace and run outside and see how many pots the smoke is coming out of - if only 1 pot is smoking then u know that it DOESN'T communicate with next doors chimney)
Hope that helps abit. If u need any more info then just pm me mate.
