I'm looking at replacing my aged wood stove with a more modern, efficient model. I'm interested in a free standing hearth mounted stove that will be used as a primary heat source during the winter. Long burn times are key, (we get up several times a night with our current machine), and a cooking surface is highly desirable. I've been looking at several Jotul models. I'm curious about the F55 Carrabessett and the F50 Rangeley. I'd prefer to avoid an ash drawer, so would lean towards the F55, but the cook top on the F50 is appealing. I've seen a couple of reviews of these, but would be interested in any input anyone might have. Thanks.
