Napoleon offers both traditional and contemporary vent free products. The Plazmafire models run at 20,000 BTUs, which is only half of the maximum amount of gas input allowed by code. These contemporary products are primarily designed to enhance the ambiance of the room without producing a significant amount of heat. The TORCH, for example, is a very aesthetically pleasing and eye catching design element that can be added to any room because it is only 6,000 BTU. It is not meant for supplemental heating.
Napoleon's vent free log sets burn much hotter and are designed for supplemental heating. These log sets are 40,000 BTU and are 99.9% efficient meaning they are effective in taking the chill off of a room. The vent free burners come with either log or river rock media and are available in 18", 24" and 30" sizes.
