Hello all, Let me start off by saying that I know very little about wood stoves, so I thought I'd turn to this forum for guidance. I just moved into a 576 square foot house with a wood stove. The wood stove is the only source of heat. Someone is offering me an airtight wood stove for free, and I wasn't sure if I should accept it or not. Here are some pictures of what I have currently have, as well as the airtight stove. The airtight stove is a Quadra Fire. Thanks for the help!
