I am new to this board so bear with me if I have not placed this in the right forum. I am currently finishing my basement and the current furnace that is installed in our house can't take the additional load of heating the basement. Replacing the furnace with a larger one is out of the question. With that being said, I am looking for some ideas/suggestions as to what path I should take. Our basement is about 800-1000 square feet and most of it is underground. The walls are insulated and it remains at at constant 60 degrees and a humidity level of around 47%(this is with the dehumidifier running). The other important information is that I live in upstate New York. Any help/suggestions would be much appreciated. Thanks in advance.
