I have a mid 1970's vintage Earth Stove 100 series in my basement that I'm using to heat my entire house, and it does a good job. I'm trying to decide if upgrading to a newer stove would help me reduce the amount of wood I burn or not. Maybe better basement insulation and a smaller stove might be the better way to go. We usually keep the house at comfortable 76 to 78 degrees. I think the old Earth Stove is probably rated around 100,000 BTU. We only have to fill it up and run it hard on the coldest days. The rest of the time we toss in a log or two and have it set on medium. The house is 1200 square foot with R19 walls upstairs, an open stairway, and uninsulated concrete block basement walls with about 2 feet exposed above ground. I'm thinking maybe an Englander 30 or possibly a 13 if I insulated my basement. I also like the Pacific Summit or the Hearthstone soapstone stoves. Am I crazy for thinking of tossing this perfectly good old stove?
