I'm sure this question has come up time and time again, but I am curious what folks thoughts are on the jotul combi-fire 4 ? I know what to check as far as cracks and t what issues may arise with the brick lining. My question is how safe for in home use as a secondary heater and though frowned upon my intention is to use it in a garage during the winter months while puttzing in the shop. There is no gas or flammables kept in the garage so we can skip that part of the code violation conversation. Garage is roughly 25x25 insulated and has an upper office space above which I plan to cut floor vents for to heat it some. The 4 that I have in mind is under $200 . My other option was a jotul 8 but then the cost jumps way up as well. any advice would be appreciated. thanks !
