We bought the double-circulator of SEGULA specially for the winter. Our living room has a ceiling height of about 5 meters with a gallery and the rising warm air from our fireplace accumulates above. The gallery is then terribly hot and the housing cool down. Here, the double-circulator was used. He should push the warm air from our gallery back into the living space. The double-circulator masters this task already perfectly at level 1. The only slight downside is the volume, the level 1 is already clearly audible. If, however, radio / TV a little louder, it is ok.
