Looking for an insert to heat at least my open concept 1st floor, which is about 2200 sqft. The fireplace is inland and in the "great" room which has about 14 foot vaulted ceiling but the rest of the level is 9 ft ceiling. Would a sirocco25 do the job or should I look for something bigger like a regency ci2700. I need overnight burns so I need a cat or hybrid stove
