we have a wood stove downstairs and it has no fan and when we are serious our regular heat does not come on, it works that well...not that the upstairs is toasty, but we don't like it too warm anyway....

my question is....with a wood stove downstairs, can the upstairs fireplace (currently with a gas fireplace that works poorly) also have a wood insert?....does two fireplaces mean two chimneys?

Maybe somebody here can answer your question, cherry.

“..does two fireplaces mean two chimneys?”

Not if the fireplace upstairs is right over the one downstairs...then they would be sharing the same chimney. They would each have their own seperate flue liner “run” in that one chimney, though. Depending on the age of the house this set up of sharing the same chimney but seperate flue liners would have been done due to the building code...it’s safer, in other words. Enjoy.
