I really like this fireplace. It is the same sizes as my TV and I am able to build a floor to ceiling decorative fireplace, framing both in. 

The other day my furnace went out, 25F outside. The fireplace was able to heat half my living room to comfortable temp. 

The one downside, the flames are not realistic. The follow the same pattern over and over. I think slowing the blue flames and added more to the outsides edges, would improve it a lot.
