We have a direct vent Natural gas fire place. It is not an insert. I do not recall the size but it is one of the small size fire places from one of the big box hardware stores. It was about $400.00 and includes a circulator fan. We bought it to take the chill out of our ground floor which includes the family room 1 bath, guest bedroom and laundry room. All are on a concrete slab. Our home is 2-1/2 stories and an open floor plan from family room to the up to the cathedral ceiling, which is roughly 25' to the peak. The lower level was basically unusable in the winter months it was always cold and damp as the heat would go straight up to the top of the house. The heater works well enough to heat the lower level but also the living room, kitchen and dining room areas.
