I've got a stove in the basement. It seems like I've received a lot of advice that the cinder block would soak up heat like I wouldn't believe, and maybe that's so. The fact that the stove my stove room is blazing hot while the rest of the house could use a five degree lift leads me to suspect that my problem is moving the heat about, not loss to the concrete foundation. Am I correct? I'm trying to figure out where to aim my efforts first - installing floor grates? or insulating foundation walls?
