I really like my electric fireplace. It gives the room such a warm ambience. I like that the colors can be changed as well as the height. The blower on the heater works well but at the time I can’t provide a true assessment of how well it heats as we just moved in, the room is an open plan and we don’t currently have window treatments or furniture in that room. However, I can say that we can definitely feel the heat blowing. My guess is that when the window treatments are in, it might feel a lot warmer. That aside it is aesthetically pleasing and I am very happy with it. 
Note: because of the wattage pull we had a dedicated outlet put in such that we can keep it on, with everything else during the day, without tripping circuits.
