I've been very happy with this unit. This is it's 3rd year of service. It will heat the 18x30 cathedral-ceiling room to where skivies are optional. lol My only gripe is that my vinyl siding is smoked a bit. The air must need adjusting. The flame, "logs", and "coals" look great though. It sat with a cement board face for over 2 years, with the rest of the addition complete, until I finally got off my arse and made the wood mantle just before this past Thanksgiving. The slab is bluestone. The rest is slate tile. The hammered face my wife chose cost almost as much as the fireplace ! It's all nice, but I like my new (to me) wood stove better. :coolsmile: I kinda wish I had one in this room.
