Sleek contemporary addition to my room. I was concerned that a fireplace this size would make my room too hot. The room is located above an insulated garage. The room is about 250 square feet and has three windows. I purchased the 50 inche unit. The heat comes out the top of unit from a vent that is about 6 inches wide. It is relatively small. We have to preheat the room before we go to bed. It takes awhile to get there, but it does get the room to a very comfortable temperature. Our only compla3 is that we cannot use the heat without the lights. It essentially becomes a huge nightlight for our daughter - she doesnt mind that at all. The lights and decorative options are beautiful. The timer feature is wonderful. I would purchase it again.
