I LOVE this fireplace. My bedroom (despite MANY efforts) is somehow always a good 10-15 degrees colder than the rest of the house, so I bought this hoping it would take the chill out of the air. 
I installed it in a wooden mantle that I had previously installed on very old brick, and it adds such a wonderful and cosy ambiance to the room. It also manages to make the room almost too warm if I put it on a high temperature, which is something I didn't think was possible in there. With the sleep timer.. it has completely changed my bedroom for the better, and now I want them in every room
