Hi friends, we've got a 1350 sq ft manufactured home in asheville NC and we're wanting to install a fireplace. It gets the teens for about a week or two in the winter but otherwise hovers in the lower 30s. I'm trying to figure out which size fireplace is appropriate for our space. I know that they all come with a heating capacity range but I'm not sure how that relates to average winter temperatures, or heating up the corners of a home that have lots of twists and turns. We've been looking at the Vermont castings for a longer burn but open to anything though we're hoping to buy second hand (and would love glass windows). Would the Aspen c3 be big enough? Other suggestions?
