We have a very large stone fireplace in our living room, but lugging in large logs every time we want a fire was getting to be to much. Sooooo we put this wonderful log set into the fire box and it not only gives the look of a living fire, but with the flue closed we do not see most of the heat going up the chimney. Can't recommend enough for those who have gotten tired of bringing in the wood, starting the fire, cleaning the fire box and the starting all over  again. In addition, so much heat is lost going up the flue that you are really warming a room. Great alternative to a gas fire log set.
