We have a closet that we use for storing household cleaners, like pine sol, lysol, toilet bowl cleaners, drano etc. Immediately behind this closet is the central cinderblock chimney of the house, connected to our woodstove and furnace.

When we run the woodstove for any length of time, the whole stack gets very hot (and spreads heat evenly through the house). But inside that closet it gets very warm.

Question: right now the closet has a solid wood door that traps the heat - would it be better to install a louvered door to allow the heat (and possible fumes?) to escape? Or better to keep any possible fumes in the closet?
