I just got one as my Christmas gift from DH. I have always wanted a fireplace, but it would have been crazy to install a gas FP, so we went with electric and I LOVE it! Ours is a pretty big one - I can get details on size for you if you want - and it throws a good amount of heat. The last couple of weeks have been so cold here and turning the fireplace on has really taken the dampness out of the living room. DH said he was really surprised by the heat that it gives off. And it really only costs us cents per hour to have it on. It has been great!
It also has an air purifier which is nice. We also got a flat screen TV for on the wall above the fireplace and I just love it all.
