Love our cozy fireplace! This is the best purchase of 2020 by far. The insert has options for heat or flame and two modes for each. It even has an option to use heat only or flame only. Extremely quiet. For the price I also found it was the most “real” looking. Also, loved the dimensions as it was much taller and more square to fit best in my chimney. Would purchase again! Oh, and I bought the 27” x 35”.
