Who exhausts out of their house?

oh really???

Well-Known Member
So I'm venting out of my chimney. The questions are. . .

Will the heat from a 400hps make steam if it is vented into a cold environment?

will the exhaust cool before it hits the outside?

I don't want my neighbors to see steam venting from a chimney. Also the exhaust has to travel about 30-40 feet to exit the chimney.

do you really think the neighbors are gonna think ur growing weed cuz theres steam coming outta ur chimney?? i find that kinda funny..
 
It wont steam, even if its a non working chimney, in older houses Heating systems and water heaters usually are vented through the chimney.

I don't think steam from my chimney will mean "pot grown here" but I would like to have no trace. The house is old. It has a basement with a secret room equipt with hidden door. I run my exhaust between the wall into the chimney. The house doesn't have a fireplace. It did but they covered over it. No other pipes go to the chimney. They all are in different places. I used to live two houses down as a kid, and the neighbors (most) know me. I never used to smoke. So I would rather scrub the air and dump it between the floorboards than exhaust steam out of a non-working chimney.

. . .But if you guys say that no steam will be created I will let you know. Thanks

shouldnt be a problem but why not vent to the attic?

Just get a good carbon filter and spread the heat throughout the house. This is also very effective against FLIR... FLIR is utilized, by the man, to detect suspicious hot spots. If you spread the heat to every room of the house, it will look like any other house, and not raise any suspicions...

chimney is a great hot spot, it suppose to be, the other good thing out venting through the chimney is you shouldn't need a carbon filter, no noses 35, 40 feet in the air to smell it. I dry in my wood stove and it goes out the top

This would be fine, as long as you are complying to your state's laws regarding cultivation. I exhaust to my attic, and have the duct aimed directly at spinny vent on the roof. So, if a pig were to fly over with FLIR, I would have a very suspicious trail of heat exiting my house 24/7. But, since I have only 2 immature plants at the time, I am 10 plants under my state's limit. So, I am not worried about the heat trail. If you are going over the limit, then do not exhaust to your attic. Even if the heat is contained in the attic 24/7, it will show the pig using a FLIR, that you have a room in your house that is suspiciously hotter than the rest of your house.

Huh??? I suggested a carbon filter for the smell, beacuse I suggested spreading the exhaust throughout the house... FLIR should not be under-estimated in my opinion. But, to each his own... Happy growing!

Chimney exhaust is fine. People get nailed when they vent out of other areas of their home. Like their garage for example.

Chimney and dryer exhaust are about equally effective. Still though, I would use the spread method if I was going big. A good FLIR operator knows what "normal" chimney and dryer vents look like, and could conceivably mark your house for further FLIR investigation (ie: 24 hour surveillance) since nobody uses these 24/7... This is why I feel FLIR should never be under-estimated...

FLIR detects thermal hotspots. They cannot see UV light, meaning they can't see light radiating from a room through your shingles on your roof. They can only identify heat that is escaping from your home. They compare images from one year to the next, and if they identify some major changes, they may have concern. And just because heat is coming out of your chimney now, doesn't mean that it wasn't a working chimney for the past few years or cannot be used now. . I doubt you will even have any heat coming out during the winter after passing 35-40 feet of brick chimney. Do you have a fan pushing it out your chimney, or do you just let the hot air rise out naturally?

I wasn't thinking of the winter cooling factor...

I use a squirrel cage blower to push the air out.

Tapping into a chimney has to be done correctly to keep the draft correct. And can be a code violation in some areas.

(definetly get a CO alarm.)

What is a CO alarm is it a CO2 alarm?

And i'm exhausting a 400 watt hps via cooltube. What would be the code violation?

The exhaust is running directly into a port premade above the flue in the basement. The chimney is pulling the air up.
