Not been burning wood for very long(couple months). Been looking into buying a new stove to replace the older stove I bought last year. Our home is 2600 sqft. Fairly well insulated and I winterize the windows in the upstairs. Basement windows are all double pane insulated . Our stove is in the basement which is open to the upstairs . Our current stove is a reg. buck and it heats very well. Just can't any good burn times out of it( that's the only reason I have for replacing it). Been looking at osburn 2400 and englander nc30. Would like to hear from anyone who has one of these and similar sqft to heat. Thanks
