It definitely can! If you spend most of some time in certain rooms of the house, you'll install a ceiling fan heater in each of these rooms to stay them warmer. which will allow you to show down the thermostat and not need to keep the entire house so warm. These fans are ready to heat an area that measures approximately 20' x 20' with a 10' ceiling. That's pretty good if you think that about it. That's bigger than most bedrooms or family rooms.
