Building a new home and want a large fireplace, but with a housing blower to provide heat for the house. It will be in a 1760 sq ft room with 19' high cathedral ceilings. Would really like a 50" wide opening to burn large logs in. Having trouble finding what I'm looking for. Wondering if I need to have one custom built. Have one in a manufactured home now, looking for the same idea, but larger scale. Don't want the add on blower I've seen for a zero clearance unit. An ideas?
