CO2 From Appliances?

I know that this is a another dumb question but I need to know why.

I was on the net and saw a CO2 generator. Out of curiosity I looked at it. It was designed for green houses and was just a metal box that has burners in it.

These units produce 3 cubic feet per burner, per hour and they typically come with several of them.

I don't know much about CO2 reactors but they have controllers that limit the amount of gas that is injected into the water. I don't know how much CO2 is needed for these units.

Could you get CO2 from the pilot lights of appliances in the house?

I thing that I could just pull the exhaust from the housing unit with a high temp tube that goes to a normal one and finally into a standard air pump. The two issues that I see are that there might not be enough volume and the CO2 might come with so much regular air that the concentration would be too low. Carbon Monoxide is suppose to be less of an issue in a clean burning blue flame.

Is this just not worth the trouble?

I would very quickly go to the "not worth the trouble," considering CO2 is generally under $3 a pound and I can go for months (if not a full year) on a 5 lb bottle of CO2.

CO2 is a product of combustion, so yes your house hold pilot light is continuously producing it.

Not worth the trouble!

Thank for the context. 15 to 50 a year is not to much, once you pay for the hardward.

Now, what if you want to grow green water. Whould you need higher volume? Would it help in the speed and amount of growth? Finally, (and this is a seperate question) would adding CO2 reduce the chances of crashes?

I just refilled my 5# bottle, 13 months out of it and it cost a whopping 17 bucks.

That pretty much puts the number to it...
