I was browswing the net and came across the following article regarding stove installations in basements: http://www.woodstove.com/pages/basement_install.html While my Woodstock Keystone is not installed in my basement, my house is a brick and block home with plaster applied directly to the interior block. Since my house was built in the 50s, there is no insulation either inside of, or in between the brick and block. While I understand stove installations in unfinished basements are generally not a good idea, I hadn't really considered my home to be like one giant basement. However, because my house is block instead of frame built, does this mean that the heat from my stove is leaving my house about the same as it would in an unfinished basement, as described in the article regarding the area of basement walls above the frost line? If so, I seriously need to begin putting up some stud walls with insulation.
