Hey guys i have my upstairs fireplace that i have not used yet. I would like to get doors here eventually. Ive heard stolls is good. and probably around 800 bucks.The install fairly easy on these ase well? I would like to use it. And someday maybe put the blazeking insert up there. but for now i would like to see if you guys think im loosing a lot of heat out up that chimney. i guess i probably am. but just dont know if its worth it to block it it off for the winter. i never have before but am considering covering it up this year.
