This fireplace advertises that it can heat up to 150sqft, but after installing it, it is nowhere near 150sqft.  I have to be within 2ft of the vent in order to feel any heat at all, which makes this unit, at best, able to heat about 10sqft.  We had it on for hours, hoping that maybe it will *eventually* heats up, but it didn't change.  At least the lighting was nice, but that's a poor consolation prize for a fireplace.  I would have returned this unit if my general contractor hadn't thrown out the box.

I could not/would not recommend this to anyone who's looking for at least a functioning electric fireplace.
