Hello fireplace experts, I am building a new home and am looking for a direct vent fireplace for our family room. Our family room is about 20x20 with 15 feet ceilings. Mainly, I want the best looking fireplace and log set and slim profile. Am in California, so heating is not a priority. I have narrowed down my fireplace choice to these two models mainly because they are the slimmest 40" wide fireplaces that i have found: Mendota dxv42 or the Kozy heat thief river falls. i have not been able to see the Kozy heat in person as the showroom did not have it on display, but i like the specs on it because you can get the black enamel liner option instead of firebrick. Would love your input as to which you think would be better-- which would probably be less maintenance/have fewer problems, and which is best looking? thanks for any advice!
