I was looking at some houses and a few had those double sided fireplaces smack dab in the middle of the house. The perfect place to heat a whole house and get everything. However, it came to mind that I don't think I ever saw a double sided fireplace insert. Has anyone come across this? Is there a solution for this? If I face an insert one way, what what I do with the other side? As I am typing this, I imagine you would place 2 seperate fireplace inserts in there facing bth sides sharing the same flue???
