30 years ago I had an Earth stove and love that unit. I have not had that stove in 20 years. (long story) Over the last month or so I have been looking at Craigs List and Ebay for another Earth Stove to put in my pole barn. In the last week I found this site looking for information about the different models of Earth stoves. I believe I had a model 500 and it could put out the heat. ( just what I need for the barn) Well my ultimate plan is to try and sneek the stove into the house in the next year or two but after reading the storys on how much better the new ones are, I am starting to wonder. I could load that stove up twice a day and it would heat the house quite well but I had to clean the chimney every 3 weeks. Are the new ones that much better than the old? Do they burn as long and put out the same amount of heat without the same amount of creosote? Like I said I want to move this into the house eventually, so I wont be running it as hard in the house as out in in the barn. I am starting to get up in age where I don't know if I want to be climbing on the roof to be cleaning it out every 3 weeks. What is everybodys thoughts?
