Didn't feel that this unit warms up the space.  You can feel the warms if you sit right in front of it within 1 meter. Once you go further or sit on the left or right side of the log - no warmth at all and doesn't warm up the room even a bit. Very disappointed. Also, the flames don't really look like real fire; the only good thing is the sound which is useless if the unit neither warms up the room nor looks like a real fire.  I had a high hope based on other reviews but unfortunately will be returning it.
