I am thinking about and planning ahead as to how I will heat my finished attic space. I have already had some heating and cooling guys come in and explain that based on my setup there is not a really good way to run ductwork to my attic. With that said, are there any safe options. The space is about 250 sq ft. It really is only a few degrees cooler than the main level, and I have added new insulation to the attic. I didn't want to use space heaters for safety reasons. Any other affordable options?
