Stove is new to me...just getting the hang of how it works and its "appetite". During the middle of winter, lets say 20 degrees... How much or how often do you have to keep feeding the stove to maintain a cozy temp(75 degrees)? I know there are variables...size of house, insulation, type of stove, on and on. Generally speaking are you in the stove every two hours? something like that? is this just the nature of the game?
