Old Fisher - came with the house. Out of business some time ago. Can't find any info on it. Probably way down there on efficiency, but built like a tank. The two cast iron doors come off easily, and there's a screen that can pop in.
Works for us, though. Our only source of heat other than a few portable electrics that I hate to use, and one functional baseboard heater. Used only if somebody is sick and needs it warmer.
Fisher Grandma since 1980, forgot about the screen. Ex and I used to put it in, fire up the blender, throw a quilt on the floor and watch movies. Funny, we never saw the end of one:msp_wink:
