I am in the market for a new stove but I'm not sure what I want. There is a waiting list for Harmon Stoves here in Schoharie County NY (as well as everywhere else or so I hear) so I won't be able to get one until early next year. First some background, We are currently in the process of buying a house, an 18 year old single story ranch in the mountains, 1500 sq. ft. The stove will be installed in the basement. The basement is about 1/3 finished and we may finish more. I have a 30 yr. old Godin that my father gave me that I will use for the for now until I can get a harmon along with electric baseboard that is in the house now, if we need it. I would like to get some feedback from sf-250 owners on burn times, how much coal does it hold and how much do you burn in a year and is this stove too much for my application? Does anyone think a Mark III is better for my house. The stove will be the primary source of heat for the house. Whatever feedback I could get to help me make my purchase would be muchly appreciated.
