The fireplace was purchased as a replacement for a much older Dimplex model and comparatively it's a big improvement. Smaller footprint, better heating, more realistic flame, etc. Manufaxturier claims it will heat 1,000 square feet. I'm not sure how that claim is validated, but in our experience it's not accurate. Ours is in a 400ish square foot room (admitededly in a 75 year old house and with three exterior walls) and it does a passable job) Others have mention the Fahrenheit / Celsius issue on the display - we never did get it to convert, so we're living with it which is not a huge issue. Also, the remote and sensor are somewhat particular about their arrangemt to one another. Again. Not a huge deal but a small noticeable one. Overall it's probably all one can expect.
