I am running a Pacific Summit Classic wood stove to heat my 2500 sq ft home located in Southern Arizona in the Sky Islands (5200'). When the temperature gets below the mid 30's, no matter how much wood I burn, the stove cannot keep up with the cold air being drawn in around my windows and doors. Throughout the night, the temperature inside the house drops... Does anyone know what increase in efficiency I would see if I installed a direct air inlet from the outside (crawlspace) to my stove? Thanks in advance.
