Hello out there, this is my first post but I've been burning for about 3 years. My question is--while burning my pot belly, would I get more heat from it if the door is open or closed? That might seem like a silly question but here is my dilemma...yes the fire feels hotter when the door is open but that also means its consuming more oxygen compared to ithe door being closed...which means it'll burn through faster. On the other hand if the door is shut, that means a slower burn because of less oxygen to combust and it also means the door will heat up and radiate heat....so to recap, which gives off more heat, keeping the door open or closed? Thanks to all who reply.
