A lot of good information. I have noticed during years of using a little a little cheif a problem with insufficient heat during cold weather even with the box on the unit for insulation. I finally realized that if (after the fish was sufficiently smokey) I let the chips turn to charcoal, then let them burn, that process releases a lot of heat. Now I save the charcoal from the early stages in a metal pan for heat during the finish. If you think this is to much hassle the oven or a microwave also works great,for finishing.
