Rooster's and Chickens

[Maggot]

Why would anybody design a methane vapor ventilation removal system? Just don't install it in the first place.

The chicken shit created the methane and it became overwhelming at times it was basically a pcd coated steel hood on one end of the building with an exhaust fan and an intake from the other side with a long sleeve about 120 ft long with holes in it that mixed the air near the ceiling called a sock made from nylon. like a make up air unit all it really did was mix the air from the top of the structure pushing the heat and methane down the side with the exhaust kicking on after about 10 min. It created positive pressure in the building so the methane was mixed better and not so concentrated. They noticed about 30% heat recovery from the system after a few years of use and the air was a better quality afterwards. its used quite a bit now in larger buildings just to mix the heat from the ceiling back down into the space.

Your mom may benefit from the same type of setup in your bathroom.
