I have a new addition to my home that is 400 sq ft. with cathedral ceiling and all windows (12) and two all glass doors-sort of sunroom style-but it faces North. The room open up to the rest of my home if I keep open the old patio single door--There is no heat source out there and a friend has offered me her Jotul Firelight wood stove (that's all I know about model of stove) as they moved and in their new home, it is not needed and has been in storage for many years.

After reading comments by others, i am wondering if I should pick it up from her as i don't want to be over powered by the heat and not able to use my new room. Any ideas??
